Bridge Crane Components
The Bridge – The bridge is made up of either a single girder or a double girder (depending on the requirements and configuration) and also a set of end trucks at either end. The bridge spans across the width of your bay and this travelling section is considered to be the main structure of your crane.
End Trucks – Bridge crane end trucks are positioned on both sides of the span and this is where the bridge wheel assemblies are housed, thus allowing the whole crane to travel along the complete length of the bay. The wheel assemblies in the bridge end trucks travel along rails which are mounted to the runway beams.
Girder(s) – The crane girder or girders are connected to the end trucks and they are the structure in which the trolley is supported. Girders are the large horizontal boxes or beams and they are considered to be a principal element of the crane.
Trolley Hoist – This component is made up of the hoist and also the frame of the trolley. In dual hoist applications, two hoists can either be mounted to a single trolley frame or two trolley frames can be manufactured each with an individual hoist.
Trolley – The bridge crane trolley rides across the span of the bridge; along the girder or girders and it also carriers the hoist.
Hoist – The hoist has one main feature and that is to lift and lower the desired load. The hoist is fixed to the trolley frame and can use either a hook and/or custom lifting attachment to carry the load. You can get one of 2 types of hoists; either a Munck electric wire rope hoist or an electric chain hoist. The wire rope hoists manufactured by Munck are dependable, durable, and are designed for years of long term usage. Chain hoists on the other hand are designed for lower capacity operations and are ideal for light duty requirements or new projects where price is a strong factor when selecting the proper lifting equipment.
