An under running crane, also known as an underhung crane or underhung bridge crane, is a type of overhead crane that operates on an elevated runway system. Unlike a top running crane where the bridge girder is supported on top of the runway beams, an under running crane's bridge girder is supported from below by the runway beams.

Single girder EOT (Electric Overhead Traveling) cranes are widely used in various industries and applications. Some of the key application fields of single girder EOT crane manufacturers include:

The double-girder bridge crane has superior performance, compact structure, light weight, reliability and operation, and can meet various working conditions.

The parts of bridge cranes that need lubrication and commonly used lubricants are described in the following sections.

Port gantry cranes are essential equipment in the efficient operation of seaports worldwide. These large gantry cranes are designed to handle the heavy lifting and movement of cargo between ships and docks.

Construction gantry cranes are indispensable in large-scale construction projects, where heavy materials and equipment need to be lifted and positioned with precision.
