Chunhua Cranes share with you what should be noted for safe use of overhead cranes?
1. The driving must be in a normal state, especially the safety devices, such as the braking mechanism, sound and light, signals, interlocking devices, etc. must be sensitive and intact.
2. When the work is terminated, the crane must be parked on the parking line and the hook must be raised in place. No heavy objects should be hung on the hook. Put all the controllers and joysticks to the zero position, pull off the power switch, and lock the cab door.
3. Bridge cranes must be equipped with reliable and sensitive safety devices. Generally equipped with buffers, limiters (stroke limiters, lifting limiters), lifting limiters, windproof rail clamps and so on.
4. During the work, the operator should concentrate on the work, and then idling before lifting, and then lifting. If the lifting object is found to be 100 ~ 150mms off the ground, it should be re-bound if it is not tightly bound. A signal bell should be issued before driving; hanging objects must not be passed over the head. When the crane is running, it is strictly forbidden to repair, inspect, refuel, and test the machine parts. If any fault is found during operation, it must be stopped immediately.
5. The shell of all live parts of the crane should be reliably grounded to avoid accidental electric shock to the operator. When the trolley track is not welded on the main beam, welding grounding should also be adopted, and the step-down transformer should be grounded on the low voltage side according to regulations.
6. Bridge cranes must not be hoisted under the following conditions;
(1) Unmanned command or command signal is incorrect.
(2) Defective driving equipment or failure of safety devices.
(3) Overload lifting or equipment quality is unclear.
(4) A person stands on or under the lifting object, and hooks the person with a crane.
(5) The light is dim and the vision is unclear.
(6) The hoisting object has sharp edges or diagonals, and no safety measures have been taken.
