A bridge crane runs on an elevated runway system along the length of a factory and provides three axis of hook motion (X, Y, and Z). The hoist moves the load up and down, the trolley moves the load right and left, and the bridge of the crane moves the load forward and backward. Both single and double girder overhead traveling bridge crane designs allow very precise hook positioning and gentle load placement. Double girder cranes typically provide better hook height, but single girder cranes offer other advantages depending on your application.
Advantages Of A Bridge Crane:
- greatest flexibility for hook coverage and control over the load
- fewest number of physical obstructions on your factory floor
Types Of Bridge Cranes
1. Top Running Bridge Crane:
By incorporating a pair of single flange wheels, the bridge crane can ride directly on top of our runway beam, without using a costly crane rail. A top runner, as opposed to a top running bridge crane can provide substantial savings in eliminating the need for both purchase and installation of the crane rail. Top runner cranes are just as durable and long lasting; they are built to the same CMAA Class D heavy duty standards for decades of use.
2. Underhung Bridge Crane:
The end trucks of the underhead bridge crane ride on the bottom flange of the runway beam. Typically, an underhung runway is suspended from the roof of the building and is available only on lighter capacities, usually 10 tons or less.
