Hydraulic Excavator Safety Manual

To ensure safety, follow the basic rules

The knowledge, experience, and ability of the operator are the most important factors in the safe operation of the machine. it is therefore important that the operator has read and understood the instruction and has been trained.

Excavator operator qualified

The driving and operation of hydraulic excavators must be entrusted to specialize and trained operators in perfect psychophysical conditions. The operator must be aware of all hazards and safety measures associated with the operation of the excavator. The operator must therefore be authorized, trained, and sufficiently skilled to do so.

Familiarise yourself with the instructions and warnings

This manual and the plates and stickers on the machine give the information required for operating it safely and properly. The user must familiarise himself with this information; failure to do so may result in serious accidents. Do not leave anything to chance if you have failed to understand it. Your dealer is always pleased to give you any supplementary information you require. If you lose or damage the manual, the plates, or stickers, contact your dealer for new copies.

Health and safety

Take special care of your mental and physical health and note that the operator of a complicated machine should be physically fit. Never operate the machine under the influence of alcohol, medicines, or drugs of any kind.

Snug fit work clothes

Your work clothing must be snug, without lose sleeves, rings or other jewelry, as they may become trapped in moving parts. Before operating the excavator, clean all grease and mud off your boots. Always wear the necessary clothes and accessories, including helmet, safety gloves, visible clothing, safety boots, and ear defenders

Check your excavator

Before starting work, walk around and check the excavator and make sure that there are no persons or obstacles in the work area.

Never take anything for granted

Today, as you start work, do not assume that everything is OK, only because it was all OK yesterday evening. Before starting, carefully check the excavator for signs of wear and defects.

Make a work plan

Before starting work, carefully inspect the work area. If there are any obstacles or hazards, notify all affected persons of their presence. Avoid overlooking anything that may cause an accident. Prepare a work plan and procedures and inform your colleagues accordingly.

Be careful of public utility lines and pipes

Before starting work, inspect the work area. identify all gas, service, sewer, overhead, and underground electrical lines, and any other obstacles and hazards. The worksite supervisor is responsible for marking the locations of all underground utility lines to prevent accidents. If necessary, ask for the said lines to be closed or transferred.

Work area

ALWAYS, before starting work, carefully inspect the work area and identify any hazards. Do not operate the machine close to a drop.
Given that the machine is not designed for use in explosive atmospheres, NEVER operate it inside a tunnel or explosive area to prevent the risk of explosion. The machine is not roadworthy and must be used only on the worksite; if necessary, it must be moved to other areas by truck

Keep your eyes open

Keep your eyes open before and during your work and especially when you slew the tools in crowded areas. In more complicated situations, we recommend using an assistant who can supervise the area and give signals; pay attention to his signals before operating the excavator.

Maintain good ventilation

Do not use the machine for indoor works. Take all precautions to vent exhaust gas externally before starting the engine if working in a hole in the ground, tunnel, or trench. In such a place, the air tends to stagnate.

Breathing exhaust gas is very dangerous. Note that exhaust gases are fatally poisonous. In case of excavations or earthworks involving noxious substances, the user must take all the necessary safety measures.

The use of excavators for lifting operations, particularly on construction sites, has become more common over the last few years. Excavators and backhoes are designed for rapid earth moving and are not designed for lifting operations as their principal function.

Excavator Lifting Capacity Chart

When it comes to moving heavy material quickly and efficiently, you need hydraulic horsepower, the type of ground-breaking power the excavator can deliver.

But did you know that one of the most frequent jobs performed by excavators is lifting?

On a typical job site, excavators may be used to lift, move and place a range of materials. Learning to lift safely is critical for anyone who owns or operates an excavator. Let’s begin with the basics.

How to read excavator lifting charts?

The versatility of hydraulic excavators is virtually unmatched in the world of construction equipment.

Whether it is compact, mid-range or large hydraulic excavators, these machines are ideal for lifting, moving and placing a wide range of materials.

As a result, it is important that hydraulic excavator operators are trained to properly lift loads or materials.

Excavator Lifting Capacity Chart

Learn the basics

The rated lifting capacity of any hydraulic excavator is determined by two factors: the hydraulic lifting capacity and the tipping load.

Hydraulic lift capacity is the point where the excavator is limited by its hydraulic power to lift a load. Tipping load is the point where the excavator begins to tilt or lift off the ground when lifting a load.

Manufacturers test according to standards to determine how much weight the excavator operator can lift and turn at various heights and distances from the machine’s centerline.

Based on these tests, manufacturers develop lift capacity or load rating tables, which are provided in the machine’s operation and maintenance manual or in the cab area for the operator’s reference.

How to calculate lifting capacity of a excavator?

Find your excavator configuration.

The lift chart on your excavator provides information that will keep you safe and get the job done right. At the top of the graph, you will find information indicating the configuration of the machine. For a compact excavator, this can include boom length, stick length, standard bucket weight, and quick coupler weight, if standard. The published lifting capacities assume the excavator is on a flat, level work surface.

Determine the height of the lift point.

Next, look at the left column on the lift chart to determine the lift point height, the distance from the ground to the bucket pivot pin, not from the ground to the object you are lifting.

When measuring the height of the lifting point, consider how high you will need to lift the item, including the height of the item itself, the length of the lifting device, and how high you want to position the item.

Find the elevation radius.

Now determine the elevation radius from the center line of the pivot point. This distance is shown in the top row of the elevation table.

Are you lifting on the front of the excavator or on the side?

If you are using an excavator with a dozer blade, determine if it will be in the raised position to allow travel or in the low position to optimize stability.

Calculate your lifting capacity.

Now you can find the cell in the elevation graph where the elevation point height and the elevation radius intersect. This number is the lifting capacity of the excavator. If there is no number listed, the excavator has no lifting capacity and lifting should not be attempted.

Generally speaking, as your lift radius increases, the lift capacity will decrease. Also, the side lift is generally more limited than the lift from the front of the excavator.

Operating manual for excavator

It is important to know how to read and understand the lifting table of an excavator, the tables for compact excavators contain information that indicates the standard configuration of the machine.

Operators must be aware of lifting considerations resulting from additional attachments or attachment variations, as these alternative items can reduce the effective lifting capacity of a machine.

For example, the weight of slings, any auxiliary lifting devices, and the difference in weight of any attachment heavier than the standard configuration must be subtracted from the rated lifting capacity to determine the correct net lifting capacity.

There may be multiple lift tables for a large or mid-range excavator, depending on the combinations of boom length, stick length, bucket size, counterweight size, and shoe width.

Operators should pay particular attention to whether the weight of the bucket is incorporated into the lift table.

This varies by manufacturer and can affect the operator’s ability to accurately determine the lift because the bucket in use may not match the weight of the bucket used for the lift table.

Importance of site clearance

Local excavating contractors: what is site clearing in construction?

Clearing the construction site: Prior to construction, an excavating service will be taking steps to have existing structures knocked down and old foundations dug up. Also, any trees on the property will have to be cut down, and the roots will have to be removed. And finally, the ground will have to be made level.

Digging foundations

Local excavating contractors: digging footings for single storey extension

Digging the foundation: After reviewing the building plans, an excavating service will begin excavating the ground, allowing for foundation forms to be put in place. It should be noted that this process also includes ensuring that the foundation is poured in accordance with the building plans.

Grading and excavating contractor

What other ways are grading and excavating used for?

Along with leveling and preparing the land for foundation pouring grading and excavating are used for other purposes as well:

  • Site Clearing
  • House Pads
  • Land Leveling
  • Ditches
  • Basement Excavation
  • Foundation Excavation
  • Erosion Control
  • Dirt & Rock Excavation
  • Driveway & Road Installation

What factors determine the costs of having an area graded or excavated?

There are many factors that go into determining the cost of grading or an excavating project. You need considers these factors:

  • Size of the Property
  • The Density of the Land
  • Erosion Control
  • Quality of the Soil
  • Heavy Equipment that Will be Required
  • Existing Site Properties Fill
  • Dirt, Slope, Cut and Fill
  • Existing Rocks, Trees, and Bushes on the Property

If you are beginning a project whether it is commercial or residential having a quality contractor is essential for success. Every building project begins with clearing the land and preparing it before a foundation can even be poured. If this is not done correctly it can result in drainage issues, erosion, and more. Why not start with a professional? Beginning a project correctly with those who have knowledge and expertise will save you money in the long run.

Why Do You Need Excavating Contractors?

Excavation contractors own a number of responsibilities than just moving around the dirt. They prepare the site, perform grading and trenching as well as other tasks associated with soil. Therefore, you must know why you need an excavating contractor.

Just after the survey of the land, lot or a typical residential area, the excavation contractor comes to conduct the compaction tests of the soil.

This is to ensure that the soil is removed to the depth, so a new foundation could be established. The contractor does the testing with equipment if required. To match the grading done in surveying, the contractor ensures that the excavation requirements are met. It is critical as the grade level is precise.

Excavation contractor starts to work on the new foundations; meanwhile, the stem wall and footers are poured by the foundation contractor. Being the sub-contractor of the large project, excavation contractors are business owners.

They work under the general contractor, who manages their schedule, bids, and payments. However, you can contact the excavation contractors for your house works; like digging the pool. This only includes a specific job and not the entire project.

What are excavating contractors?

What is an excavating contractor?

An excavating contractor is someone who can operate a heavy piece of construction equipment called a grader and hold a CDL license. A grader is a heavy piece of equipment that can smooth and flatten the surface of the soil for roads, foundations of homes, and other building projects.

What is grading and excavating?

To further understand what a grading contractor is you need to understand more about the process of grading and excavating. Grading and excavating is the process of preparing the land for building. This can be done by smoothing out the soil, flattening an area, building an area up, or sloping it to a certain degree that is needed.

What is grading in construction?

Grading is the leveling of a given area in preparation for pouring foundations of homes or businesses. Grading is not a DIY project that just anyone can undertake themselves. That is why legally to run a piece of the heavy equipment you are required to have a special CDL license. Professional contractors will also have the expertise to determine what angle your slope will need to be when leveling so water will run away from the buildings you are constructing.
However, grading cannot happen until your building site has been cleared of any obstructions.

What is excavating in construction?

In contrast to grading excavating is about digging up and moving earth with equipment. After trees and undergrowth have been cut down and removed from a property the area may still have obstructions that need to be removed. These can be large stumps, boulders, other large rocks, or any other organic material that is in the way.

Backhoe Bucket Attachment

The backhoe is the main tool of the backhoe loader. It’s used to dig up hard, compact material, usually earth, or to lift heavy loads, such as a sewer box. It can lift this material and drop it in a pile to the side of the hole. Basically, the backhoe is a big, extremely powerful version of your arm or finger.

Amphibious Excavator

Amphibious Excavator – swamp excavator: Amphibious transporters have been specially designed to work in swamp areas and river deltas. Transporters consist of an undercarriage and an upper structure with cabin, engine, and platform.

The machine can be custom-made to suit your needs. The structure is also inter-changeable. Transporters are multi-functional and can be used for a wide range of purposes. This includes:

  • Passenger transport
  • Equipment transport e.g. drilling platforms
  • Dumper for ground transport
  • Possible to convert to the amphibious excavator

The undercarriage of transporters is the same as that of amphibious excavators. The transporter has a lot of traction and is able to extract itself from riverbeds, while pontoons have sufficient buoyancy and low ground compression.

Amphibious Excavator
Amphibious Excavator – swamp excavator

Floating excavator

Amphibious excavators are easy to transport. The advantage of excavators with an adjustable undercarriage is that they can be transported in one go. Pontoons can be extended and retracted.

Watering machines weighing more than 15 tonnes are no longer adjustable. This choice was made to reinforce the platforms and pontoons used on heavier machines. After all, they do not need to be retracted.

Despite the fixed undercarriage, transport is more efficient than with adjustable undercarriages. Higher class adjustable excavators exceed transport dimensions. This means a special permit must be requested, which unnecessarily delays transport and makes it expensive. Amphibious excavators can be assembled and dismantled within one and a half hours.

Machines of 20 tonnes or more are almost always used on large projects. This almost entirely eliminates the advantages of adjustable undercarriages.

Amphibious transporter: The upper structure can be transported separately from the undercarriage. Assembly and disassembly can be realized within an hour. The machine also complies with transport norms when it comes to height, width and length.

Some industrial uses of Amphibious Excavator

Dredging often is focused on maintaining or increasing the depth of navigation channels, anchorages, or berthing areas to ensure the safe passage of boats and ships. Vessels require a certain amount of water in order to float and not touch the bottom. This water depth continues to increase over time as larger and larger ships are deployed. Since massive ships carry the bulk of the goods imported into the country, dredging plays a vital role in the nation’s economy.

Amphibious Excavator
Amphibious Excavator – swamp excavator

Dredging process

Waterways come in different forms and some are just impossible for the conventional excavators to work on. Amphibious excavators are specifically designed to take on such harsh environments up to 2-meter water depth. Amphibious excavators can be equipped with a hydraulic dredging pump that can pump silt from the waterway floor over a long discharge distance of up to 500 meters.

Deep excavations and tunneling in soft ground

Amphibious excavators are best suited to work in the interiors where soft grounds are often encountered. The excavators are equipped with floats that prevent them from been bogged down in the peat soils. Lumber clearing within soft grounds can be achieved with amphibious excavators.

Shoreline construction

With increasing weather changes and often unpredictable floods, amphibious excavators are often used to build up the shorelines for flood prevention. Levees along the riverways can be easily built using pontoon excavators.

Riverbed deepening

River deltas often require constant de-silting & deepening. Marsh buggies are suitably designed to carry out such river deepening work. Rivers mouth require scheduled deepening as if they are neglected, flooding happens.

Landscaping services

Increasingly, swamp excavators are employed for landscaping areas that are near riverways and shorelines. The amphibious excavators have to be used because conventional excavators can easily slip & sink into the soft ground and get immobilized.

Highway construction

Highways do traverse different types of ground conditions. In construction, and where there is a waterlogged & swampy land area, the amphibious excavator can be easily deployed to work on the soft ground. It is also used to dig up tree stumps that if left underground.

Oil exploration

As mankind’s dependency on fossil oil increases, finding more of the black gold requires the search in remote areas that often required special machines. Amphibious excavators have found use in the transporting of men and equipment into these areas. The benefits of pontoon fixed excavators is that they are very mobile.

Pontoon excavator

Ponton excavator or amphibious excavator is a type of excavator that can perform dredging while afloat in shallow water. An amphibious excavator is better adapted for removing silty clay, clearing silted trenches, swampland operation, and shallow water operation than traditional barge-mounted dredgers.

The amphibious excavator can walk or work in water because the chassis crawler floats on sealed pontoons. It may swing or even roll over when excavating with no support underneath. It moves using a dual-body boat form buoyancy tank. A reducer drives the crawler chain, allowing free and smooth movement. Its upper structure is a modified excavator that allows 360° full rotation and hydraulic operation.

Amphibious undercarriage

The machines have been developed to operate in poor load-bearing areas. The undercarriage is designed and built to have maximum buoyancy and low ground pressure. The low ground pressure ensures that the surface will have limited damage.

Other than that the amphibious excavator can be built with a new or used upper structure of choice. It is also possible to purchase only the undercarriage (this consists of two pontoons and a mounting frame).

All machines are durable, safe and have proven reliability. The amphibious excavators are efficient and they have a strong construction. The undercarriage is made of Cor-Ten steel and the bottom plates and wears strips are made of Hardox. Critical parts of the machine are protected to make sure they can’t get damaged by the use of the machine.

The upper structure is placed at the center of the machine. This has as an advantage that the machine has a working range of 360 degrees and that the machine can be customized and equipped with extra options such as an extra fuel tank. Equipped with heavy-duty travel motors the undercarriage has a high tractive force.

Amphibious excavators can be used on land as well as on water. This means it is possible to easily cross swamps, moats, lakes and other waterways.

Pontoon mounted excavator

The amphibious excavators can be equipped with additional pontoons. The pontoons provide extra stability and buoyancy of the amphibious excavator. By adding pontoons to the machine it is possible to work in water with a depth between 4-6 meters.

The additional pontoons are built to fit the model of the undercarriage of choice. The pontoons are extra long, high and wide for extra buoyancy.

The spud poles measure 20 x 20 – 30 x 30 cm and because of their strong robust appearance the spud poles make sure that the machine is stable and can use more force while working. The spud poles are designed to go through the pontoon instead of being mounted on the back. This makes the entire structure of the machine and the pontoons stronger.

The pontoons are built with integrated steps to have easy acces to the cabin. The steps and deck of the additional pontoons are covered with an anti-skid surface. The coupling system is easy in use and due to several locks

What is hydraulic excavator?

what is the difference between an excavator and an amphibious excavator?

Excavators are heavyweight construction equipment whose house is outfitted with a cab, a boom, a dipper, and a bucket. The house is a rotating platform that rests upon an undercarriage with a track system. An operator controls the apparatus from the cab. A boom is connected to the house and has a stick attached to the end known as a dipper, providing adequate digging force to pull the bucket through the earth. Buckets come in a host of sizes and shapes to perform a variety of functions.

Many other attachments are available to be used with the excavator to employ in various applications, such as cutting, crushing, or boring, for example.

Hydraulic dredging equipment

Amphibious excavators are a type of excavator designed to be used for dredging in shallow water. They are better equipped with their pontoon undercarriages for operation in swamp/wetlands operations that traditional barge-mounted dredgers are ill-equipped to handle. Barge-mounted dredgers are better suited for deeper fresh waterways.

Amphibious excavators are engineered to have the most stable undercarriages constructed from the most reliable, state-of-the-art components available. Each undercarriage is fabricated to the specifications of the attached equipment to supply the lowest ground pressure, the best maneuverability, and the highest degree of buoyancy possible.

Amphibious Excavator

What is dredging?

Dredging is the removal of sediments and debris from the bottom of lakes, rivers, harbors, and other water bodies. It is a routine necessity in waterways around the world because sedimentation—the natural process of sand and silt washing downstream—gradually fills channels and harbors.

What are the benefits of dredging?

The advantages of dredging are: Widening and Deepening: Dredging can be a critical process for the commercial shipping industry. Removing sediment can maintain the appropriate width and depth for enabling the safe, unobstructed passage of cargo vessels carrying oil, raw materials, and other essential commodities.

How is dredging harmful?

Sediment can smother seagrasses, which are the key food source of dugongs and sea turtles, and damage corals. Some activists want to dredge to be banned completely, blaming it for releasing toxic chemicals, increasing water turbidity and littering harmful metals throughout the food chain.

Why dredging is needed at the port?

In the shipping industry, dredging is generally carried out to increase the channel or port depth for ensuring proper bottom clearance, to improve navigation and sometimes also for reclamation purposes (to reclaim material and use it later on land or in port development).
