characteristics of the work.

The crane is in a range of vertical and horizontal movement of goods hoisting machinery, and the intermittent movement of the crane operation cycle characteristics of the work.
Which category has several cranes
The crane is in a range of vertical and horizontal movement of goods hoisting machinery, and the intermittent movement of the crane operation cycle characteristics of the work. By Application: General cranes, construction cranes, metallurgical cranes, railway cranes, port cranes, shipbuilding cranes, deck cranes. By tectonic Category: bridge type cranes, jib type cranes, rotary crane, non-rotating cranes, stationary cranes, crane operation, operation of cranes and rail and non-rail line. Common Model: electric single and double girder, single girder, double girder gantry, cantilever, electric single girder suspension, single and double girder grab, explosion-proof single, double girder, metallurgy single, double girder, scissor pallet truck gantry cranes, manual single beam, suspension, bridge machine, etc.result of improper operation of the driver, and some circuitry accident was due to a fault in itself caused.
Therefore, the relevant electrical components and electrical specifications alignments is particularly important if the quality of the product itself does not pass, it is easy to cause a failure to form a safety hazard.
How Jigging quality guaranteed products? Or to look for national testing. The relevant specifications is also very important, and if there are no standard or develop is not clear, if there is a problem and can not be repaired, we should make this as brief as possible, and a number of senior electrician advantage.
