Press the tray-bearing and suspended two. The former car beam electric hoist manufacturers along the orbit; the latter at the plant along the suspension bridge truss crane orbit. Single girder overhead crane sub-manual, electric two kinds. Manual single-girder overhead crane operating speeds lower bodies, since the weight is small, but the quality of their small, easy production, low cost, suitable for small amounts without power after handling, less demanding on the speed and productivity occasions. overhead bridge cranes with manual monorail car as the car is running, hand pull gourd as a lifting mechanism, the bridge from the main beam and end beam components. Main beam generally use single beam, side beam is formed by bending steel or steel welded
