Beam crane selection

Over a rectangular space in its operations, and more for workshops, warehouses, open yard loading and unloading goods, etc., a beam cranes,  bridge crane  , gantry cranes, Cranes, carrying bridges.
① crane beam: beam cranes including single girder overhead cranes and double girder overhead crane
Single girder overhead crane bridge girder to use more of the word steel or steel type with steel composite section. Lifting trolley often chain hoist, electric hoist or hoist as lifting mechanism parts assembly.
Press the tray support and hanging two. The former car beam bridge crane along the orbit; latter along the suspension bridge  Steel crane  under roof in the plant orbit. Single girder overhead crane of manual, electric two kinds. Manual single girder overhead crane agencies working speed is low, since the weight is also smaller, but their quality is small, easy to organize production, low cost, when used without the power handling of small, less demanding on the speed and productivity occasions. Manual single girder overhead crane with manual monorail running as car, hand pull hoist as lifting mechanism, the bridge from the main beam and end beam components. Girder generally use a single beam, side beam is formed by bending steel or steel plate welded into.
Electric single girder overhead crane working speed, high productivity compared to manual, from the weight as well. Electric single girder overhead crane from the bridge, traveling mechanism, electric hoist and electrical equipment and other components.
② bridge crane:
overhead bridge crane is the bridge in orbit a bridge crane, also known as the crane. Bridge crane bridge laying on both sides along the elevated tracks run vertically, lifting trolley along the track on the bridge laying sideways to form a rectangle scope of work, you can take advantage of the space under the bridge lifting materials, not hampered by ground equipment.
Bridge crane is widely used in indoor and outdoor warehouses, factories, docks and open storage yard, etc.. Bridge crane bridge crane can be divided into ordinary, simple beam bridge crane bridge crane and metallurgical dedicated three.
General overhead cranes generally lifting trolley bridge operating agencies, bridge metal structures. Lifting trolley and the hoisting mechanism, trolley run institutions and small frame of three parts.
Lifting mechanism includes a motor, brake, reducer, drum and pulley. Motor through reducer, driving drum rotation,gantry crane so that the wire rope around the drum or from a roll down to lift heavy loads. Small frame and mounting bracket is lifting mechanism and trolley run institutions and other parts of the rack, usually welded structure.
