What is a tower crane?

What is a tower crane? – Tower cranes are widely used for lifting operations in the construction industry. Tower cranes are a common fixture at any major construction site. They are pretty hard to miss… they often rise hundreds of feet into the air and can reach out just as far. The construction crew uses the tower crane to lift steel, concrete, large tools – like acetylene torches and generators, and a wide variety of other building materials.

What are tower cranes used for?

The operating characteristics of a tower crane are largely determined by its type of mounting, type of tower and type of jib.

Static tower crane

A tower crane with a static base only occupies a limited area but is able to cover, from its fixed position, all points at which loads are to be handled within the maximum slewing radius. They can be set at varying heights up to their maximum free-standing height. They can also be extended beyond this limit by tying the crane back to the supporting structure.

Rail mounted tower crane

Rail-mounted tower cranes have a larger area of coverage as they can travel along their tracks carrying their rated loads. However, the height requirement should not exceed the free-standing height as recommended by the manufacturer.

On the other hand, the crane service would be disrupted whenever work must be done on or near the track. The advantage of mobile tower cranes lies in great inward reach without the long jib which would normally be required to reach over the top of the structure.

Self erecting crane

Generally, truck-mounted tower cranes are completely self-contained and can be driven along roads. They are generally capable of comparatively rapid erection and dismantling. They are however generally unable to travel in their fully erected state and cannot handle loads while traveling.

Crawling tower crane

Crawler-mounted tower cranes are required to be transported on a low-loader or towed on special road axles when traveling on public roads. Inside the workplace, some can travel over a firm, flat, level ground carrying loads up to a specified proportion of their rated loads.

They are also able to travel in a partially erected state but without load over unprepared ground provided it is within certain limits of level and compaction.

Tower crane jib

A horizontal trolley jib usually has a smaller minimum operating radius than the equivalent luffing jib and is thus able to handle loads closer to the tower of the crane. For a given height of the tower, however, a greater height of lift is available with a luffing jib, and the jib can be raised or lowered to clear obstacles. One advantage of a fixed luff jib is that its extra height at the jib head enables it to clear objects that would obstruct a horizontal trolley jib. The advantage of a rear-pivoted luffing jib is that it has a smaller minimum hook radius than an ordinary luffing jib.

Articulated jib crane

For articulated jibs, some designs are not required to weather vane. In this case, the crane is made to withstand storm winds with the jib drawn into minimum radius; there is then no need for a 360° obstruction-free slewing path. One type of this crane has a hinged jib arranged so that the outer portion remains horizontal. As the jib is folded, the outer portion rises, giving increased height and the ability to pass over obstructions.

What type of crane do I need?

The selection of a crane for any job should be made only after a thorough examination of all the factors involved. In general, it is good practice to select a machine that has a working margin in respect of the load capacity and other anticipated requirements.

The crane should have a permanent durable plate bearing the manufacturer’s name, machine model, serial number, year of manufacture and weight of the unit for identification purposes.

Every major structural, electrical and mechanical component of the machine should have a permanent durable plate or a clear indication bearing the manufacturers’ name, machine model number, serial number, year of an original sale by the manufacturer and weight of the unit.

Besides, identification numbers should be clearly marked on all basic removable components and attachments of the machine (such as counterweights, etc.) to show that they belong to that machine. It is important that these components should be used only on that machine or identical models or equipment for which they were specifically intended by the manufacturer.

How is a tower crane built?

Tower cranes are mainly fixed on construction sites. Construction sites use tower cranes from large tools such as lift steel, concrete, acetylene torch and generators, and a variety of other building materials. Tower cranes are mainly used to transport and lift capacity from one place to another.

What wind speed Do cranes stop working?

A common “rule of thumb” is considering stopping the crane if the wind speed reaches 20 mph. Project managers and Appointed persons should reconsider lifts if the wind speed increases dangerously, even before it reaches 20 mph.

Tower Crane Equipment

A tower crane is a construction machine designed to load and unload different materials. This load is distributed through the use of a hook that remains suspended thanks to the use of a cable.

Self Erecting mobile Tower Cranes

Self-erecting tower cranes have long been commonplace in Europe. Their versatility and reliability have made them a mainstay on the European Jobsite. That same versatility and reliability are now practical for the Canadian market. Roblin Crane Services can provide you with self-erecting cranes for all your lifting needs.

Tower Crane Hand Signals

Tower Crane Hand Signals: Cranes have been in operation for more than 2,000 years, having been invented by the ancient Greeks. Today, there are a wide variety of cranes found at construction sites, such as truck-mounted cranes, rough terrain cranes and crawler cranes equipped with tracks.

The basic components of mobile cranes include a movable boom attached to a platform. The boom can be raised or lowered, as well as rotated to move a load horizontally. There are also cranes with telescoping booms. A spool with steel cables extends to the end of the boom and attaches to the load. A powerful motor provides the force to move the boom and raise or lower the load.

Most cranes also have heavy counterweights to help offset the weight of the load. Many cranes have outriggers to increase stability and help ensure that they remain level during operation.

Tower Crane Hand Signals

Crane operator hand signals

Using standard hand signals is the most widely used manner of signaling a crane operator. A hand signal chart can usually be found on the side of the crane or it should be conspicuously posted in the vicinity of where hoisting operations are being conducted.

Under the current OSHA crane standard there are only select instances when a signalperson is not required and for all those other times; having a top-flight signalperson should be a priority.

Every successful lifting operation is the result of planning and teamwork. The definition of teamwork is “a united effort by all to achieve the ultimate goal”. All lifting operations must be undertaken by a trained and competent team using a safe system of work established prior to the start of any lifting operation.

You as the tower crane operator play a vital role in the team and the aim of this guide is to give you essential practical advice to help you carry out this role successfully.

Should you have any doubts or questions regarding the information you must take this up with your employer before proceeding with lifting operations.

Hand signals in crane operation

Hand signals for tower crane:

Tower cranes are also widely used. The jibs on most tower cranes are secured in a horizontal position and rotate on their pedestal.

The load can be raised or lowered, and travel horizontally along the length of the jibs.

Tower Crane Limitations:

It is important to be aware of crane limitations, such as their load limits. The further the load is moved from the center of the crane, the less weight the crane can lift. For example, extending a telescopic boom reduces its lifting capacity. Also, lowering the boom decreases the crane’s load limit, because the load moves further away from the crane.

When a crane picks a load, the boom often deflects downwards. This is called boom deflection. This can present two hazards. It lowers the cranes lifting capacity by causing the load to be further from the crane. It can also cause the load to swing as it lifts off.

Crane Hand Signals:

Standardized hand signals are commonly used by the crane signal person. The signal person is the only one who should give signals to the operator. The only exception is if other personnel see a hazard, they can use the emergency stop signal. When the signal person gives directions to the operator, they must be from the operator’s perspective.

Tower crane voice signals

As with hand signals, voice communication between the signal person and the operator should be continuously maintained during crane movements. Directions should be given from the direct perspective of the operator.

Each voice signal must contain the following three elements, given in the following order: function (such as hoist, boom, etc.), direction; distance and/or speed; function, stop command. The operator, signal person and lift director (if there is one), must be able to effectively communicate in the language used.

Tower Crane Hand Signals

Tower crane radio signals

Voice Signal Communication

In situations where hand signals are not appropriate, voice signals are an option. Portable radios are often used. They should be tested before crane operations begin and they should use a dedicated channel. The crane operator must use a hands-free device. Verbal signals should be short and clear. They should include three key elements, spoken in this order:

  • The function and direction
  • The distance and/or speed
  • Function stop

The function names should be the same as the hand signals described earlier. Here are some examples of proper voice signals:

  • Boom up. Slowly. Slowly. Boom stop.
  • Lower load. 10 feet. 5 feet. 2 feet. Lower stop.

The function, such as Boom, Lower, Swing and Travel are spoken first, followed by the direction or speed. The signal to stop always has the function first, followed by a stop.

Construction site hand signals –

Non-standard and New Signals:

A situation may arise where standard signals don’t communicate all the information the operator needs lift. In that case, a new, non-standard signal may be used, as long as it is clearly understood by the operator, signal person and lift director.

General Safety Considerations:

An overview of basic safety precautions is described.

  • Typical PPE will likely include hard hats, safety glasses, gloves, high visibility vests, and work boots.
  • Before the lift begins, check that the load hook is centered over the load and that the rigging gear is properly set. Also, check that the load stays centered during the lift.
  • Watch for power lines to be sure the boom or load doesn’t get too close.
  • Watch the boom deflection closely to make sure it doesn’t exceed the load radius.
  • Make sure other personnel stay out of the crane operating area and always keep yourself and others from under a suspended load.
  • The rotation of the cab and counterweights presents a hazard. Stay well away from its rotation zone.
  • Avoid using your hands to control a load. Use a tag line so you can stay a safe distance from the load.
  • When an operator is moving a load horizontally, it may swing if the boom stops suddenly. Stay well away from swinging loads.
  • Also, pay close attention to weather conditions.
  • Lightning and strong side winds can produce serious hazards.
  • The steel boom can act as a lightning rod and the wind pushing on the load and boom can make cranes unstable.

Hand signal for crane operation and their meaning

High Wind Conditions and Taking the Tower Crane Out of Service:

It is important that you monitor the wind speed constantly using the anemometer display in the cab. This will give you early warning of rising wind speeds and enable you to take action to take the tower crane out of service and descend the tower whilst it is still safe to do so. If the wind is gusting around the limiting wind speed it may be appropriate, following consultation with your supervisor, to remain in the cab whilst establishing if the wind speed is rising or falling.

Crane safety hand signals

Crane safety hand signals: You should report the wind speed to your supervisor on-site on a regular basis. Where the wind speed is rising this will allow the site plenty of opportunities to plan concrete deliveries etc, before the crane has to be taken out of service.

The anemometer or other windspeed indicators must be included in the daily pre-use checks.

Putting the crane in the out-of-service condition generally includes ensuring that the jib is free to “weather vane” when out of service so that the minimum wind area is presented to the prevailing wind.

On luffing jib tower cranes it is also important that the jib is left at the correct out of service radius (specified by the crane manufacturer, which is not always the minimum radius. This will ensure that there is sufficient wind area to enable the crane to “weather vane”.

When taking the crane out of service on multi crane sites you must ensure that the crane in free slew will not enter the area of other cranes that are still operating.

Tower cranes must not be left out of service with a load on the hook and the hook must always be fully raised.

Tower Crane Hand Signals

Where can crane operator hand signals be found?

A hand signal chart can usually be found on the side of the crane or it should be conspicuously posted in the vicinity of where hoisting operations are being conducted.

Who can give signals to the crane operator?

During crane operation, only one person can give signals, unless it’s for an emergency stop – then anyone on the job site can give the signal. Once the qualified signal person is identified, the signal person and the crane operator must identify each other prior to giving any signals.

Who can give an emergency stop signal to a crane operator?

Anyone who becomes aware of a safety problem must alert the operator or signal person by giving the stop or emergency stop signal.

Anti collision system for cranes

After a year-long market study, it has been seen that most of the tower cranes do not have anti-collision systems. Even the Safe Load Indicator (SLI) is not installed. Some tower cranes have safe load indicators but are unable to link with the anti-collision systems.

Multiple monitors/displays in the operator’s cabin also confuse the operator and lead to accidents. Frequent power failure at construction sites adds problems like improper shutdown, data corruption, non-detection of radio signals, restart, etc.

Tower Crane anti collision System
Tower Crane anti collision System

Anti collision device for cranes

After studying all these problems, an anti-collision system has been developed with built-in SLI and wind velocity control that gives tremendous safety for any make/model tower cranes.

These anti-collision devices (ACD) come with a ground monitoring system through which one can monitor the functions of all tower cranes as well as upload data changes (like height increasing, protect some zones, etc) without stopping the cranes.

A single display shows the anti-collision functions, as well as the SLI, functions like load, radius, hook height, slewing angle and wind velocity to the operator without any confusion. This system integrates with the tower crane panels and will take care of the cut-off, alarm and display automatically without changing any OEM set-up.

This system is developed with a microprocessor, with battery backup so any power failure at the site does not affect the functioning. The communications are made through radio controls with non-licensed frequencies.

Working principle of anti-collision device

The Anti Crane Collision Switch is designed to avoid the collision of two adjacent cranes in the same bay running on the same rails. This system, when installed on the two adjacent cranes, will avoid the collision of two cranes. The system works on the principle of retro-reflective infrared waves. It consists of an emitter and sensor module and a special reflector.

The emitter emits the infrared waves in the direction of the reflector. The reflector reflects these infrared waves back to the sensor. The sensor senses the presence of these reflected infrared waves and activates an alarm signal and stops/reduces the speed of the crane. Thus if the two cranes are away from each other then the reflected waves will not reach the sensor and the crane operate normally.

The distance between the reflector and the sensor to detect the presence of infrared waves can be adjusted with the help of the potentiometer provided on the system. The maximum distances between the two crane to generate the alarm signal can be a maximum of 10 meters. The anti-collision system is specially designed for the Crane application and is suitable for continuous duty.

Anti Collision and zone protection device can be easily installed with any make or model tower crane. The same device can also be used as a safe load indicator.

This system provides a clear visual position to the crane operator about all the installed cranes, structures, towers, and even trees as programmed around it by which the collision/accidents will be avoided.

The system includes a high-performance microprocessor, Software, wireless radio communication system and sensors to deliver accurate communication, data analysis, control, braking and data storage features. Touch Screen Monitor makes the installation and site setup simple.

It should come as no surprise to anyone in this industry that the second most common type of serious tower-crane incident reported in the last decade relates to contact with overhead power lines.

Unwanted contacts – between two cranes or between tower cranes and power lines.

While none of these reported incidents resulted in injury or death, several caused temporary power outages for thousands of nearby businesses and homes, many resulted in lost time or materials and damage to costly machinery, and all had the potential for serious injury, death, or catastrophic equipment failure.

As per the regulatory requirement, tower cranes and ancillary equipment involved in the incidents all had to be inspected, repaired if necessary and re-certified for use.

This statistic has helped guide the crane inspection team in developing its three-year Tower Crane Strategy, one element of which is a focus on raising awareness of the value of digital zoning and anti-collision devices.

Slew-limiting technologies have advanced steadily over the last 20 years. Sensors, interfaces and the software used to analyze the data have become very reliable, making the benefits for safe and efficient operation indisputable.

what causes collision?

The collision of tower cranes may occur when two or more cranes over-sail with each other, any crane over-sail to the site’s boundary or to a prohibited zone. An example of a collision is the crane’s hoisting hook block & cable collides with the main jib.

High rise crane operator salary

The skyline of any city will likely include at least a few tower cranes, which are among the largest pieces of equipment used in building projects. Construction companies use tower cranes to lift heavy materials such as steel and concrete.

Just as cranes tower over building sites, the salaries of the people who run them tower over those of other construction workers.

Some high rise crane operators and related trades in New York City make upwards of $500,000 a year in pay, overtime, and benefits, according to the Real Estate Board of New York, which represents the construction industry.

But the real reason New York crane operators and other operating engineers earn such big salaries is overtime and benefits. A relief crane operator working 56 hours of overtime per week for 52 weeks will earn $335,000 in overtime and $160,000 in overtime benefits at the World Trade Center. As a worker’s salaries go up, so do the amounts employers must kick in for annuities and pensions.

Work rules in New York at the World Trade Center require that every crane operator be accompanied by a relief crane operator and an oiler a person that starts up the crane for the entire time a crane is operating.

High rise crane operator wages – Tower Crane operator training

Tower crane operators are specialists in the construction industry who operate a specific piece of heavy machinery that lifts, transports and moves construction equipment and materials all over their construction site.

These materials are needed to build concrete foundations, floors, walls, decks, roofs and other parts of high-rise buildings and other multistory structures.

Tower crane operators must adhere to established load limits for their crane, control crane movement as instructed by their supervisors or signalers, and understand specific hand signals and/or instructions given to them via radio.

They must also be able to operate crane using remote controls or remote consoles, as well as ensure their cranes are regularly inspected to promote safe use.

Tower crane operator pay

Tower Crane operator jobs:

Other tasks performed by tower crane operators include ensuring that their cranes meet industry standards, are thoroughly inspected on a regular basis and have load capacities that are properly rated by the equipment manufacturers or qualified engineers.

Tower crane engineers must be familiar with rated load capacities that are marked on each side of the crane; for cranes that have more than one hoist, they must follow individual load ratings.

Because their job involves heavy equipment, tower crane operators must follow all safety standards closely and pay close attention to detail. Their work hours vary depending on the weather, but they generally work during daylight hours and based on deadlines.

Tower crane operator course

Most employers require that tower crane operators have completed relevant trade school training and possess commensurate work experience. Many employers require that their operators possess the National Commission for the Certification of Crane Operators (NCCCO) tower crane certification. Possessing an Occupational Safety and Health Administration (OSHA) 10-hour training program may be beneficial. Tower crane operators must be able to complete the physical requirements of their position, which include stooping, crouching, bending and using manual dexterity to operate controls.

Tower crane certification requirements

Construction, freight handling and other types of industry require the use of cranes for heavy lifting. Tower cranes, used on heavy construction sites and for freight at major ports, are among the most challenging to operate. Many states require licensing or certification for tower operators, and their salaries are among the highest in the trade.

The Bureau of Labor Statistics estimates that demand for crane and tower operators will increase by 16 percent between 2010 and 2020, roughly equal to the rate for all occupations. However, demand will be much higher in some sectors. As the economy continues to recover from the 2008 downturn, demand for operators in construction should increase by 31 percent, while freight handling in ports will create job growth at a rate of 26 percent. According to California’s Labor Market Information site, only about 10 percent of crane operators are licensed for towers, but employment prospects should be good given that both high-growth niches rely heavily on towers operators.
