Underhung Crane Solutions

What Are Underhung/Under Running Cranes?

Underhung cranes come with either a single girder or double girder bridge design. The single girder is more cost effective, but the double girder can handle longer spans and higher capacities.

These bridge girders have end trucks that are attached to ends that mount to the bottom flange of the runway rails, whereas Top Riding Cranes ride on top of the runway rail. A control panel is used to drive the end truck (and bridge) down the runway. 

A Trolley containing a hoist is mounted to the bridge which will contain the hook and lifting device. A variety of different hoists are available to accomodate any lifting application. Single girder bridgers typically have an underhung trolley whereas double girder bridges typically have a top running trolley. 

Underhung cranes are best suited for facilities that don’t have the clear height to allow for a top riding crane and in most cases, the underhung crane is supported from the existing facilities roof or ceiling structure. We also offer options for free standing versions, but support columns would be required.
