Accident of a EOT Crane can be a fatal damage to the life of a individual, hence due care should be taken while designing, manufacturing, installation and operation and maintenance of EOT Cranes. A lapse at either end can be Fatal.

This paper is towards the care to be taken during operation of EOT Cranes
- Perform pre-operational checks at the beginning of every shift.
Check wire ropes for damage.Make sure that the upper limit switch is working. The upper limit switch is a safety device designed to prevent the bottom block from contacting the upper structure. If the switch is faulty, the bottom block could damage the hoist and cause the load to fall freely.Move the crane without load in either direction in long travel , cross travel, and hoisting notice any abnormal sound if any.
(for details refer to the operation and maintenance manual)
- Center the lifting attachment over the load. With unusually shaped loads, you may have to start lifting slowly, see how the load settles, lower it back down, and adjust accordingly. It is not uncommon to course-correct several times when lifting irregular loads. Keep in mind that the extra effort is worth it; centering the load is critical for preventing the load from swinging.
- Ensure that the rigging is sufficient for the load. All rigging is tagged with its designated lifting capacities at specific configurations. Make sure that rigging can handle the load—neglecting this step is one of the most common lifting mistakes that operators make. Additionally, be sure to use softeners on slings when lifting loads with sharp edges. This keeps loads from breaking or damaging the slings.
