Features of top running bridge overhead crane

  • A top running bridge crane is the overhead crane placed the end trucks or track system on the top of the runway beam, making the bridge and hoist run along on the top of runway system. top running cranes can be configured in a single girder crane or double girder overhead crane design. A single girder bridge crane generally installs an underhung electric trolley and hoist, while a double girder crane design usually uses a top running electric hoist trolley and hoist.
  • Top running bridge cranes have unlimited capacity. Top running overhead cranes can transfer small capacity loads or very large capacity loads, with capacities of 0.25 ton to 500 tons. Usually, the overhead top running crane are supported by the supporting structure or runway support columns which can stand the extremely heavy loads.
  • Due to the crane trolley or hoist riding to the top of runway design, this types of overhead crane can added lift height for facility with limited headroom. A top running double girder bridge crane provides the greatest lifting height because the electric hoist and trolley run on top of the two bridges or girders.
  • Top running overhead crane offers higher lifting height, double girder top running overhead crane offers the greatest lifting height
  • Top running overhead crane offers higher capacity, and wider span for suspended load factor is ruled out which makes the overhead crane installation and maintenance in the future much easier and less time-consuming than an underhung crane.
  • However, on the other hand, the track or rail system of the top running overhead crane needs more inspections on alignment than an under running overhead crane does through its working life. But do not worry, the crane service and alignment is easy to conduct and requires little downtime than an under running crane.

Top running bridge cranes are the most effective lifting solution as you have the best coverage within your facility. Offered in both single, double and box girder designs, there are enough options to suit your application.
Top running overhead bridge cranes are designed to travel on top of a runway system that is either supported by engineered columns or building columns.
Double girder designs typically provide you a better hook height than single girder designs as the hoist is mounted on top of the bridge rather than underneath.

Types of top running bridge crane

Top running bridge crane is generally grouped in single girder, double girder, box girder top running bridge cranes, which are selected according to your application conditions. Top running overhead bridge cranes are designed to travel on top of a runway system that is either supported by engineered columns or building columns. Double girder designs typically provide you a better hook height than single girder designs as the hoist is mounted on top of the bridge rather than underneath.
