Bridge crane

In a rectangular field and over the job, and more for workshops, warehouses, open yard loading and unloading goods, etc., the beam cranes, bridge cranes, gantry cranes, crane cable, carrying bridges.
(1) girder cranes: girder Shipbuilding gantry cranes including single girder crane and double girder bridge crane single girder overhead crane bridge girders using a combination of multi-word section steel and steel or steel type. Often lifting trolley hoists, electric hoist or hoist lifting mechanism as part assembled. Press the bridge is divided into two kinds of support and hanging. The former car beam bridge crane along the orbit; the latter along the suspension bridge truss crane plant in orbit. Single girder overhead crane sub-manual, electric two kinds. Manual single girder overhead crane operating speeds lower bodies, from the weight of too small, but little of their own quality, ease of production, low cost, suitable for carrying small amounts without power after, do not ask for speed and productivity occasions. Manual single girder overhead traveling cranes with manual monorail car as the car is running, hand pull gourd as a lifting mechanism, bridge girder by girder and end components. Girder generally use a single beam, side beam is formed by bending steel or steel plate welded. Electric single girder overhead crane operating speeds, higher productivity than the manual, since the weight as well. Electric single girder overhead crane from the bridge, traveling mechanism, hoist and electrical equipment and other components.

(2) overhead crane:
Bridge crane bridge is a bridge crane runs on an elevated track, also known as Crane. Bridge crane lay on both sides of the bridge along the elevated track running lengthwise, lifting the car along the track laid on the bridge sideways, forming a rectangular scope of work, you can take full advantage of the space below the bridge lifting materials, not hampered by ground equipment. Bridge crane can be characterized so hang on hooks or other devices extract heavy lifting in space to achieve vertical or horizontal transport. Bridge crane include: lifting mechanism, large car run institutions. With the action of these organizations rely on, can in a certain weight lifting and handling cubic space. Overhead cranes, gantry cranes, crane, metallurgical bridge cranes, cranes, etc. are examples of such cable. Bridge single girder gantry craneis widely used in indoor and outdoor warehouses, factories, docks and other places open storage yard. Bridge crane bridge crane can be divided into ordinary, simple beam bridge crane bridge crane and metallurgical dedicated three. Ordinary general by lifting trolley bridge crane, bridge run institutions, bridge metal structures. Lifting trolley lifting mechanism also consists of 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, so that the rope around the roll or from roll down to lift heavy objects. Small frame is the bracket and install the hoisting mechanism and trolley run institutions and other parts of the frame, usually welded structures.
