Overhead Crane Safe Work Procedure

Overhead Crane Safe Work Procedure

What happens when there are structural defects in an overhead crane?

Overhead Crane Safe Work Procedure

Safety operating procedure overhead crane: What overhead crane operators always need to keep in mind is that they are responsible for the safety of other people. This is why they must be trained and authorized before they start using the crane.

Part of their training includes knowing what the crane’s characteristics are. What is the overhead crane capable of doing and what are its limitations?

So you will need to know how much weight you can lift and anything over that is dangerous. You should also familiarize yourself with the area in which you will be operating the overhead crane.

Another thing you need to familiarize yourself with is the proper terminology. There are no complicated terms to memorize here. But you should know what all the parts are called and what their function is so when it comes to maintenance and repairs; you know what you are doing.

Overhead crane operation safety rules

What are the hazards in crane lifting?

The three most common hazards involving overhead cranes include electrical hazards, overloading, and materials falling or slipping from overhead hoists.

How often do overhead cranes need to be inspected?

All active cranes must be inspected once a year at the minimum.

However, depending on the crane’s usage, additional inspections will be required. Crane inspections fall under two general categories based on the intervals between inspections.

Overhead crane safety tips

For the safety and productivity of your employees and the workplace, it is vitally important to know that the lifting equipment is in good working order before putting it into service.

  • Before use, make sure that the lift is suitable for the planned lifting task.
  • Confirm that you have the proper travel, elevation, and capacity.
  • Visually and physically inspect the lift before use.
  • Check for damage, wear, and proper operation of all functions.
  • Confirm the weight of the load.
  • Check the capacity of all equipment, including accessories, rope, and slings.
  • Do not exceed these capacities.
  • Select the proper sling for each lift.
  • Inspect slings and other rigging accessories before use to see if they are worn or stretched.
  • Do not use damaged or defective slings.
  • Use softeners on sharp corners.
  • Do not splice broken slings.

Overhead crane operation safety

When communicating with a crane operator, use clear and agreed signals. Except for the stop signal, the crane operator must follow the instructions of only one person: a designated flagger.

When using a wired or remote control, the operator must familiarize himself with all its functions before lifting the load.

  • Warn everyone in the load lifting area before starting the lift.
  • Make sure the path of the load is clear of people and obstructions.
  • Do not lift loads on anyone.
  • Center the crane hoist over the load before lifting to prevent the load from swinging.
  • Slide the sling fully onto the lifting hook.
  • Make sure the safety latch is closed.
  • Do not load the hook tip or hammer a sling into place.
  • Secure unused slings. Do not drag slings or leave loose materials on a lifting load.
  • Avoid trapping fingers when slack is removed from a crane hook or cable.
  • Get away before the lift begins.
  • Move the load and controls smoothly.
  • Minimize load swing.

Overhead crane operating procedures

These protocols are a standard part of maintenance and crane operation programs.

Walk-in front of the load while traveling and warn people to stay away. Use a slogan to prevent rotation or other uncontrolled movements. Raise the load only enough to clear objects. Do not ride on the hook or load.

  • Place loads on the lock, never directly on a sling.
  • Do not pull or push loads from under the hoist.
  • Do not leave the load or crane unattended while the load is suspended.
  • When crane operation must be restricted by other personnel, use lockout and tagout procedures.
  • Store floor slings in a clean, dry place on hooks or racks.
  • Do not leave slings, accessories, or locks lying on the ground.

Crane Load Test Procedure

Test loads should not be more than 125 percent of the rated load unless the manufacturer recommends otherwise. Hooks, hoist chains, and wire ropes must be checked daily, but heavy or severe load tests should be inspected semi-annually or quarterly.

These test reports will be filed where they are available to designated personnel.

When it comes to safety at your facility, you can’t afford to bypass any part of the equipment inspection and maintenance process, and that includes testing the equipment before you start using it in your operations.

What is a Crane Load Test?

During load tests, we will intentionally overload the overhead cranes to evaluate their condition. You should be able to safely lift and move the load through regular motions.

How do you use an overhead crane safely?

Center the crane directly over the load before hoisting to avoid swinging the load.

what standard is used for load testing cranes?

All new overhead and gantry cranes constructed and installed on or after 1971, shall meet the design specifications of the American National Standard Safety Code for Overhead and Gantry Cranes, ANSI B30.

Electric Overhead Crane

These cranes are electrically operated by a control pendant, radio, or infrared remote pendant, or from an operator cabin attached to the crane.

EOT Crane stands for Electric Overhead traveling cranes. This is the most commonly preferred EOT crane that is usually used in load lifting and shifting.

They have parallel runways and the gap is spanned by a traveling bridge. The hoist is mounted on this bridge. These cranes can be operated electrically.

What does an electric overhead crane do?

To move extremely heavy or bulky loads through the overhead space in a facility, instead of through aisles or on the floor, an electric overhead crane, also called an industrial crane, crane, or an overhead traveling crane is a machine that lifts, lowers, and moves a load horizontally.

Types of electric overhead crane

There are various types of overhead cranes with many being highly specialized, but the great majority of installations fall into one of three categories:

  • Top running single girder bridge cranes
  • Top running double girder bridge cranes
  • Under-running single girder bridge cranes.

Single girder cranes

The crane consists of a single bridge girder supported on two end trucks. It has a trolley hoist mechanism that runs on the bottom flange of the bridge girder.

Double Girder Bridge Cranes

The crane consists of two bridge girders supported on two end trucks. The trolley runs on rails on the top of the bridge girders.

Gantry Cranes

These cranes are essentially the same as the regular overhead cranes except that the bridge for carrying the trolley or trolleys is rigidly supported on two or more legs running on fixed rails or other runways. These “legs” eliminate the supporting runway and column system and connect to end trucks which run on a rail either embedded in or laid on top of, the floor.

Monorail Crane

For some applications such as production assembly line or service line, only a trolley hoist is required. The hoisting mechanism is similar to a single girder crane with the difference that the crane doesn’t have a movable bridge and the hoisting trolley runs on a fixed girder. Monorail beams are usually I-beams (tapered beam flanges).

Overhead Crane Electrical Components

Rewiring the electrical parts within a crane or hoist presents an opportunity to modernize your equipment to improve performance on a budget.

Overhauling your drive, interrupt, and switch systems can power your equipment at a fraction of the cost of buying new machinery.

Traveling cranes require circuit breakers, transformers, variable frequency drives, and surge suppressors, among many other components.

All electrical components for cranes meet industry standards set by the Crane Manufacturers Association of America (CMAA), formerly known as the Electric Overhead Crane Institute (EOCI).

Overhead crane power supply

Reliable and dynamic cable management is one of the greatest challenges in modern crane technology. While the components must be modular, they should also be consistently easy to install, low maintenance, and cost-effective.

Engineers often turn to two power supply variants to try and meet these demands: festoons and energy chains. ­

Which solution is best for your crane application? Read this tech talk and get a full understanding of the differences between the two technologies.

This section regulates voltage, cabling, design, and construction of pendant controls to protect lifting equipment operators and other personnel from electrical shock.

These specifications support OSHA, which lays out employers’ responsibilities to provide employees a workplace that minimizes the risk of arc-flash and other electrical hazards
