Overhead crane operation safety rules and safety technology

 1-ringing from the car. From the car to a smooth, steady levels of acceleration.
 2, first class hanging objects, should the goods hanging from the ground 0.5m, then down, in order to test the reliability of the brake, then normal operation.
 3, prohibits overload operation, the estimation is unclear or near the rated load of the goods available two files try hanging. Two hanging file can not afford, and then not use direct lifting high gear. 4, prohibiting oblique hanging, stayed.
5, lifting goods, prevention of sudden lifting, when the rope nearly straightened (taut), to adjust the size of the car's position while lifting one side, to prevent oblique hanging. Similarly, the landing should look at what manner, in order to ensure a smooth cargo.
6 to prohibit lifting buried in the ground, the condensation in the device relative to the ground and the vehicle cargo collusion.
7, hoist gantry crane  operation, to prevent the hook or other lifting a greater swing. Such drivers should be proficient in the "steady hook technology." "Steady hook technology" is that when the hook travel pendulum swing back when the most significant yet, the trolley (cart) to hook swing tour with the most significant step in the direction to offset hook swing back, giving the hook stable.
8, cranes lifting goods banned from the person's head over, lifting goods prohibited to stand on. Lifting should follow the specified channel, more than 0.5m above the ground objects, but not higher than 1.5m.
9, the driver in the job following shall send a signal (-ringing):
(A) lifting, falling cargo, starting size car;
(2) cranes from blurred at passed, to a continuous-ringing;
(3) Cranes in the same layer or another layer close to the cross inside another crane;
(4) when lifting cargo close to personnel;
(5) In other emergency situations
10 cranes in the normal operation of the process, prohibit the use of emergency switches, limit switches, and other means to fight against car parking.
11 cranes in operation prohibition overhaul.
12, prohibit cargo cranes hanging in the air long-term stay. Crane hanging goods, persons linked to prohibit drivers and leave work.bridge gantry crane 13, loading and unloading of container or other cargo should pay attention to:
(1) check whether the packaging is solid and strong lifting symbols
(2) linked to withdraw all personnel before lifting carriage
(3) handling a large plate or cutting edge of the workpiece, use special clamps or special tools. Wire rope lifting and hanging objects must be in the rope between the pad to the pad material.
14, a significant drop in voltage or in the case of electricity ruin, you must disconnect the main switch, pull all the controllers to zero.
15, a sudden failure of the brake lifting mechanism emergency measures. When found defective brakes,Steel crane a warning signal is issued at the same time, playing against car, pull the lift controller to the appropriate grade, repeated use of this means to size car to a safe location, and then lower cargo.
If the brakes fail while lifting mechanism did not work, immediately turn off the cab master switch, the brake solenoid power, brake brake.
16, open operation, when the wind is greater than six or more, you should stop the operation.
