What matters should be paid attention to when operating a single beam crane?
Crane driving check before startup:
Check whether there are any abnormalities in various parts of Crane driving, especially the connection of the main beam.
Check the wheel, there should be no cracks, indentation and wear exceeding the limit. When the depth of the above-mentioned defect exceeds 3mm, it should be replaced immediately.
When the wire rope breaks up to 19 wires in a lay length, and the surface of the wire rope is obviously worn, it should be replaced immediately.
Pay attention to the steps:
Test run: Under no-load conditions, turn on the power supply, start and check all operating mechanisms, control systems and safety devices, check and adjust the Electric hoist brakes, all should be sensitive, accurate, safe and reliable before use.
After finishing the work, move the Electric hoist and the operation button dial to a safe position, and then cut off the power supply.
Precautions for single-beam crane operation:
Do not exceed the lifting capacity specified by Crane driving.
It is not allowed to hold down the control buttons that turn the Electric hoist in both directions at the same time.
When lifting the workpiece, the operator should keep a distance of more than 1 meter from the workpiece.
There should be no one and no obstacles in front of the lifting. When the operator is walking with the car, he should pay attention to prevent it from falling over.
Don't pull the control cable too tightly, and keep the button plate free.
Do not lift or drag heavy objects at an angle.
The limiter is a protection device and should not be used as a switch. It is strictly forbidden to operate without rope guide or stopper, and the sensitivity of rope guide (stopper) and limit switch should be checked frequently.
The key of the power switch box is managed by a designated person. Electric hoist must be regularly maintained, inspected and lubricated by a dedicated person to avoid accidents.
When the brake does not work, adjust the tightness of the electric brake spring.
When the Electric hoist is not working, it is not allowed to hang heavy objects to avoid permanent deformation of the parts.
