Description of Overhead Travelling Crane


Overhead cranes come in all different sizes, shapes, and capacities and selecting the right type of overhead crane is essential to streamlining your production processes. There is no “one size fits all” approach to identifying the right type of crane for your business’ lifting needs, so the following need to be taken into consideration when choosing a crane for your facility:


Motion of the crane structure

Weight and type of material / load

Location of the crane—indoors or outdoors

Required capacity

How often the crane will be used

Length or span of the crane


Technical parameter of Overhead Travelling Crane

Part of the structural performance design of Overhead Traveling Cranes


Bridge – A load-bearing beam that runs the width of the building. This is the primary structural component that connects the runways and moves the hoist forward and backward using a trolley.


A bridge can be comprised of one or two beams—more often referred to as a single girder or double girder design. Girders can be made of rolled steel or can be fabricated by welding the beams into a steel box design.


Runway – What the bridge crane travels on to move the crane up and down the bays. These are typically part of the building structure, as beams, and there are two (2) per overhead bridge crane system.


Runway rail or tracks – Rail supported by the runway on which the crane travels. Top-running cranes typically run on ASCE/railroad rails. Gantry cranes can also utilize a rail or track system installed in the floor to move the bridge back and forth.



Installation And Maintenance of Overhead Traveling Cranes

Eot crane installation


The eot crane installation should be carried out in strict accordance with the rules and order of the specification. Besides, we have a professional technical team with several engineers to provide the equipment installation guide service and training. For different types of cranes, they have different installation methods, so before installation, workers should understand the structure, parameters, and installation site of the crane. During the installation, they should be careful and wear helmet and belt seat for safety. The installation work should be done under professional guidance.


Eot crane maintenance

Eot crane maintenance is indispensable in daily work for that the crane failure may directly affect the safety of workers and the equipment. A routine maintenance for hook, wire rope, reducer, brakes and other components should be done, especially the hood is the most frequently used device in the crane operation, and it bears all the loads. Once the hook gets damaged or broken, it may cause a serious accident. Therefore, the maintenance staff must be careful during inspection and solve the problems in time.
