20t Double Girder Overhead Cranes

Product Description

Double girder overhead crane is composed of bridge frame, trolley, cart operating mechanism and electric equipment and is applicable for the workshops, freight yards and warehouses in stations, ports and mining enterprises, hoisting, transporting and loading all kinds of materials in the fixed spans.
According different environments and purposses, the crane can derives many models such as low speed, explosion proof, insulation, electromagnetic, bucket grab, double trolleys and dual purposes, and triplicate purposes
Our company manufactures all kinds of double girder electric overhead traveling crane with a hoisting capacity of 5-500/80t and a span of 10.5m-35.5m.

1. The quality of the main girder decides use age and use cost of the crane. "shengqi" consummately adopt European most advanced design and manufacture craft of the main girder. Mail girder wear well , not only let user ease use, but also low maintenance cost.
 
2. The up camber curve of main girder adopt optimize 4 times curve, ensure traveling have no upgrade resistance when full loading. Overcome the disfigurement of traveling motor overload traveling and trolley slide traveling.
 
3. End carriage is box girder, and the connection between end carriage and main girder adopt high strength bolt, in order to transport conveniently.
 
4. Optimize structure design, bearing layout reasonable , bear horizontal force, improve use age of the bearing.
 
5. The connections of every mechanical part are gears, in order to achieve simple installation and convenient maintenance. The drive wheel group and driven wheel group are all supported on crescent bearing box , convenient for disassembly and adjust.  How to make an inquiry to us?
