Operating procedures
Before work
a. Before taking over the single beam bridge crane with a cab, the driver should inspect the hook, wire rope, safety device and other components according to the requirements of the inspection card. If any abnormal situation is found, it should be eliminated.
b. The single beam bridge crane operated on the ground should be inspected by a dedicated person per shift according to the requirements of the inspection card. Any abnormal situations found should be eliminated.
c. The operator must confirm that there is no one on the platform or track before closing the main power supply. When a lock or notice board is added to the power circuit breaker, the original relevant person should remove it before closing the main power supply.
at work
a. When lifting a heavy object for the first time in each shift (or when the load reaches its maximum weight), the object should be lowered again after being lifted 0.5 meters above the ground, and the brake performance should be checked to confirm reliability before proceeding with normal operations.
b. Strictly implement the "Ten No Hanging" system:
① The command signal is unclear or chaotic, and the command is not suspended;
② Do not lift when exceeding the rated lifting capacity;
③ Unreasonable use of lifting equipment or failure to securely hang objects;
④ If there are people or other floating objects on the suspended object, do not lift it;
⑤ Failure to lift due to malfunction of the brake or other braking safety devices;
⑥ When lifting heavy objects directly for processing, do not lift them;
⑦ Slant pulling and hanging without lifting;
⑧ Explosive objects are not suspended;
⑨ Objects buried underground should not be pulled or suspended;
⑩ Objects with sharp edges and corners, not suspended without padding;
c. If any abnormality is found, immediately shut down the machine, cut off the power supply, check the cause and promptly eliminate it.
After work
a. Raise the hook to a certain height, park the cart at the designated position, and place the controller handle in the "zero" position; Pull down the knife switch and cut off the power supply.
b. Perform daily maintenance and upkeep.
c. Do a good job in handover work.
Select
Firstly, it complies with the relevant regulations of GB/T14406-1993 and GB5905-86 for general gantry cranes. Generally, the lifting capacity is below 50t, the span is within 35m, and there are no special usage requirements. It is recommended to use a single beam bridge crane. If the width of the door legs is required to be large, the working speed is high, or heavy and long items are frequently lifted, it is advisable to choose a double beam gantry crane.
