Introduction bridge crane rules

bridge gantry crane operating procedures which specific? This issue is also an issue of concern, today I look for everyone to read.
Bridge crane operating procedures are:
A metal structure and working mechanism of the appearance of the situation to normal.
(2) The safety devices and the indicating instrument complete and intact.
3. The gear box, hydraulic oil tank compliance.
4 main parts of the connecting bolt without loosening; various transmission parts no oil leakage.
5 and the pulley rope wear wear around compliance.
6 overhead gantry crane  operation must be certified personnel passed the examinations.
7 before transmission, remote control handle on the zero position. Emergency stop button in the stop position.
8.JOB, should be no-load operation, testing whether the normal operation of the working body, with or without noise and abnormal sound, agencies brake and safety protection devices are effective only after confirmation normal operation.
9 lifting weights, the weight of the total weight must not exceed the rated load of the crane from the weight requirement. Must strictly abide by lifting "do not hang ten" requirements.
10 should be based on lifting heavy objects and site conditions, select the appropriate operating speed, the controller should operate from the stop point (zero) start, followed by progressively increasing the speed, the more non-stop operation. Running direction of the transformation, the controller should handle pull to zero, wait until the motor stops and then turn the other direction, the direction of rotation shall not directly transform a sudden shifting or braking.
11 In the hook lifting,hoist crane lifting trolley carts running or walking in front to limit device should be slow amble to the stop position, and should limit device to maintain a certain distance (hook not less than 1m). As a non-limiting device used to stop operation of the control switch.
12 heavy lifting, non-free fall. Place heavy objects, can be used in place institutional or slow to make use of brakes slow decline.
Heavy lifting for horizontal moves, should be higher than 0.5m above the obstacles it spans.
13 operation, when power outages or voltage drops, should immediately pull the controller to zero, and cut off the power. If there is a hook to hang heavy objects should be slightly loose repeated use brakes a little tight, so that the weight slowly ground down to safe areas.
14 After the operation, the road open to the parking position, the operating handle back to zero, press the power button, the remote control back to the office for safekeeping.
