2,General bridge crane
The smaller traveler of Model QD bridge crane is a kind of hoisting and winding device composed of motor, gearbox, brake, wind drum etc. The production cost is much higher so that we suggest to use it in case heavier goods are to be hoisted or it needs to be used frequently. Especially it has a double braking advantage for steel industry. Waterproof equipment should be prepared in case of open air operation. It has 3 operation methods as room control (open type and close type), ground control and remote control.

1,Electric single-girder suspension crane
Model LD electric single girder crane is composed of 4 parts which are main girder, end girder, electric hoist and electronic control. Main girder is made of welding-connected U beam and I beam. Traveling mechanism of the larger traveler adopts 3-in-1 traveling mechanism which is of simple structure, easy installation, operation and maintenance, of lower production cost, and used for hoisting and transmitting general goods. There are three common operation methods which are ground control, remote control and room control.
