Double girder Overhead crane for hydropower plant
Double girder overhead crane is widely-used hoisting machinery at present. It mainly consists of 4 parts, bridge frame(two main girders and two end beams), crane traveling mechanism, trolley with frame and electrical parts. The major supporting frame of the crane is the bridge frame composed by main girder of box shape, end beam, walkway, rail and operating cabinet. Trolley is located on it, trolley is a rigid frame welded by steel plate. Main hoisting mechanism, auxiliary hoisting mechanism and trolley operating mechanism are on the trolley. Crane operating mechanism is equipped on both sides of the bridge frame end beam. The electrical parts are mainly located on the walkway of crane and the operation cabin, and the power is connected to main switch of the crane with special purpose sliding wire.
Structure of Double girder overhead crane
Trolley and Crane Traveling Mechanism
Trolley and crane operating mechanism are composed of motors, reducers, couplings, brake and wheel set, etc. The wheel runs in two directions driven by reducers and couplings under driving moment generated by motors, trolley and bridge frame can achieve lifting back and forth from place to place.
Hoisting mechanism is composed of motors, reducers, drum set, wire rope and lifting hook, etc. The lifting hook goes up and down under driving moment generated by motor; the heavy object goes up and down with the hook.
Double girder overhead crane lifting mechanism can be with two trolleys, double trolley generally used for lifting special materials, its structure is safe and reliable, with strong practicability.
Crane trolley consists of one or two sets (main and auxiliary) hoisting mechanism, trolley traveling mechanism and trolley frame, etc.
The overhead crane systems are designed to meet the varied and demanding requirements of workstations and power house that need up to 200 ton of lifting capacity. They can be ceiling-mounted or freestanding, single or double girder bridges. This overhead crane, with its enclosed steel profile, is robust and strong.
Our crane are designed to accommodate a wide variety of application requirements for workstation and power house. The enclosed track profiles can be effectively cover work areas and can adapt as your production needs change.
the overhead crane is a auxiliary equipment for the turbine generator installation & maintenance in power house, the overhead crane capacity is designed according to the maximum parts of generator, and the crane span design according to the power house width.
if you want to buy this overhead crane, you need to confirm the weight of your equipment, and the width of power house.
