Cranes are essential in industries and working environments. The automobile, construction, and shipbuilding sectors are the industries that employ them the most. They’re used to lifting heavy objects and materials that are impossible to move by hand. They facilitate work and increase productivity. 

Cranes come in a variety of shapes and sizes, and they are employed for a variety of tasks. They are used by industries to meet their specific needs. Each crane is designed with its own set of functions to satisfy the needs of its users. The EOT cranes, also known as Electric Overhead Traveling Cranes, are one of the most common and popular types of cranes.

Configuration of EOT Cranes:

Under Running

The ceiling structure supports the running cranes. Cranes operate on the girders’ bottom fittings. One of the advantages of the underrunning layout is that the trolley dimensions are relatively tiny, allowing the maximum width and height of the structure to be utilized. We can protect the crane track with the existing ceiling frame.

Top Running

A girder is the structure’s main reinforcement support beam. It provides support for the smaller beams. On the top of the runway beam is a fixed rail or track system. The capacity range is not limited to the top running arrangement. It can manage both little and large loads.

How does EOT Works?

Crane capacity:

Before operating any crane, you should be aware of its load capacity. Any loads that exceed the crane’s stated load capacity should not be raised. Examine the hoist brake pedal, and if they are unable to retain the load, slowly lower the load, immediately report the problem, and do not run the hoist until repairs are completed.

Daily Check:

Before operating the crane, a daily inspection of the machine is required, and it should not be operated if any portion requires repair or maintenance. Move the crane in all directions to make sure it’s moving smoothly. Keep your ears open for strange noises, and you’ll be able to replace worn parts in no time.

No loose parts:

Make sure there are no loose parts or components. Before lifting your load, be sure there are no loose components or accessories. The hoisting ropes and sling should be slack-free, and the material should be securely fastened in the saddle of the hook.

Shut the crane completely:

You must be familiar with all of the crane’s controls, including how to stop it in a crisis. This can be done on a regular basis by turning on an Emergency switch, which must be within reach and in good condition. The function of controls should be clearly labeled.

Be prepared at the time of emergency:

Operators and site workers must understand what to do in the event of a mechanical, electrical, or power outage. In the event of an emergency, procedures for retrieving an operator from a cabin should be followed. Fire extinguishers must be carried in every cabin.

When you’re done with your operation, make sure to turn off all of the controls before leaving the operator’s cabin. Also, double-check that you’ve eliminated everything. Also, ensure that the load hanging from the crane’s hooks has been removed, that all hooks have been hoisted to a mid-position, and that the crane has been placed at a specific location.

Safety Tips for Using EOT Cranes:

 

  1. Make sure the crane is appropriate for the intended hoisting task before using it. Ascertain that it has adequate travel, lift, and capacity.
  2. Check the load weight before loading. All equipment and components, including the hardware, rope, and slings, should be inspected for capacity.
  3. Select the appropriate sling for each lift. Check the slings and other rigging hardware for wear, stretch, and other damage before installing them. Do not use slings that have been damaged. Soften sharp corners with softeners.
  4. Ensure that clear agreement indicator are conveyed while interacting with a crane operator. When using a remote controller or a wired connection, the worker should become familiar with all of its features.

Before lifting the load, the operator should become familiar with all of the functions of the remote controller or connected.

  1. Before starting the lift, issue a warning to all workers and other people in the load lift area. Ensure that the load’s path is clear of people and obstacles. Lifting loads over people is not a good idea. To avoid swaying the load, place the crane hoist in the middle of the load before lifting.
  2. Make sure you’re utilizing sling legs that haven’t been used before. On a load being lifted, do not leave loose materials or drag slings.
  3. During transportation, walk ahead of the load and warn people to stay away from the crane. To avoid rotation or other uncontrolled movements, use a tagline or quote. Elevate the load only to the point where it is necessary to remove objects. Riding on the cargo or hook is not a good idea.

Conclusion:

Electric rooftop traveling crane is abbreviated as EOT crane. The most frequent crane for lifting and transferring heavy loads is this one. These cranes are driven by electricity and are controlled by a control pendant, a radio/IR remote pendant, or an operator cabin that is attached to the crane. 

These cranes are capable of lifting both heavy and small loads. Because it comprises a parallel runway connected to a traveling bridge, it is also known as bridge cranes.
