Note the use of the yuantai bridge crane

Was hung above the bridge cranes are workshops, warehouses and open dumps, used a variety of objects lifting machinery and equipment, commonly called "crane" or "travel." It is the mechanical industry, metallurgical industry and the chemical industry's most widely used as a lifting machinery. In modern industrial enterprises, is the mechanization and automation of production processes, reduce the heavy manual labor, improve production efficiency one of the key equipment, the use of overhead cranes should note the following safety precautions:
1. The driving must be in a normal state, especially safety devices, such as the brake mechanism, sound and light signals, interlock and so must be sensitive intact.
2. The work process operator to concentrate, before lifting to idle, then lifting, hanging objects from the ground 100 ~ 150mms lifting objects found tied up when not tight, should be re-tied. Driving should be preceded by a signal bell; hanging objects may not be crossed from the person's head, starting when the crane is strictly prohibited repair, inspection, refueling and wipe the parts, found fault must immediately stop running.
3. Working termination, should the crane stopped at the stop line, the hook raised position, can not hang heavy on the hook. All the controllers, joysticks into the zero position, and pull off the power switch, lock the cab door.
The bridge crane to be fitted with a reliable and sensitive safety devices. General features buffer and stopper (stroke limiter, positioner from the ceiling), lifting limiter, wind clip rail clamp.
5. All the live parts of the single girder overhead crane housing should be grounded to avoid electric shock accident occurred operator. Trolley track is not in the main beam welding, welding should be taken to ground the transformer should be required to drop in the low pressure side of the ground.
6. The bridge crane lifting in the following cases shall not:
(1) no command or command signal is not correct.
(2) The driving device is defective or safety device failure.
(3) overload or lifting device quality unclear.
(4) people standing on the lift or lower lifting objects with a crane hook hanging people.
(5) a dark, blurred vision.
(6) lifting objects have sharp edges or the oblique oblique mention, did not take security measures.
