Operation specification for electric double girder bridge crane

Yuantai Crane is mainly engaged in the design of single-beam cranes, double-beam cranes, gantry cranes, metallurgical cranes, crane leasing, grab cranes, frequency conversion cranes, explosion-proof series cranes, chain oil scrapers, foam scrapers, and electric hoists. Manufacturing, installation, repair and renovation, and maintenance.

The engineer summarized the operating specifications of the electric Double beam bridge crane as follows:

(1) Check the brakes, hooks, wire ropes, safety devices and other components according to the requirements of the spot check card. If abnormal phenomena are found, they should be eliminated.

(2) When the power circuit breaker is locked or there is a notice board, the main power supply can be turned on only after the original person concerned removes it.

(3) When hoisting a heavy object for the first time in each shift (or when the load reaches the maximum weight), the weight should be lowered after the height of 0.5 meters from the ground, and the brake performance should be checked. After the reliability is /confirm/ied, the normal operation should be carried out. operation.

(4) During the operation, the operator should ring the bell and alarm for the following operations according to regulations.

(5) Operation should be carried out in accordance with the unified command signal.

(6) When there is a sudden power failure during work, all controller handles should be placed in the "zero" position, and the crane should be checked for normal operation before restarting work.

(7) In the normal operation of the crane and the trolley, it is strictly forbidden to turn on the reverse brake to stop; when changing the movement direction of the crane and the trolley, the handle must be placed in the "zero" position, and the mechanism can be driven in the reverse direction after the mechanism is completely stopped. .

(8) For cranes with two hooks, when the main and auxiliary hooks are switched and the height of the two hooks is close, the main and auxiliary hooks must be operated separately to prevent the two hooks from colliding.

(9) It is not allowed to stop using the limit position limiter, and it is strictly forbidden to adjust the lifting mechanism brake under load.

(10) If an abnormality is found, stop the machine immediately, check the cause and eliminate it in time.
