Bridge crane safety issues that should be considered

   bridge crane  is Hengjia in workshops, warehouses and open dumps on top of various objects to lifting machinery and equipment, often called a "crane" or "traffic." It is the mechanical industry, metallurgical industry and chemical industry's most widely used as a crane. In modern industrial enterprises, is the mechanization and automation of production processes, reduce heavy manual labor, increase production efficiency is one of the important equipment, the use of  overhead bridge crane  should note the following safety precautions:
    1 vehicle must be in normal condition, especially safety devices, such as brake mechanism, sound and light, signals, interlocking devices and so must be sensitive intact.
     (2) work process operator to concentrate, before lifting idling, then lifting, hanging objects from the ground 100 ~ 150mms lifting objects found tied up is not tight, should be re-tied. Driving should be preceded by a signal bell; hanging objects from a person's head can not be crossed, crane motion, the non-repair, inspection, refueling and wipe the parts, found fault in the operation must immediately stop.
     3 Working termination, should the crane parked in the parking line, the hook rose bit, not on the hook hanging heavy objects. All the controllers, joysticks into the zero position, and pull off the power switch, lock the cab door.
     4 crane must be reliable and sensitive safety devices installed. Generally equipped with buffers and stopper (stroke limiter, from the ceiling positioner), lifting limiter, wind rail clamp clamp.
     5 cranes all live parts of the shell, should be grounded to avoid electric shock accidents operator. Trolley track is not welded to the main beam, we should take the welding ground, reducing the transformer should be required in the low pressure side of the ground.
     6 crane lifting in the following circumstances shall not be;
     (A) no command or command signal is not correct.
     (2) Driving device is defective or malfunctioning safety device.
     (3) the quality of equipment overload lifting or unclear.
     (4) people standing lifting objects or lifting objects, using the crane hook lifting people.
     (5) a dark, blurred vision.
