Top running overhead travelling crane designs

Top running crane is very flexible and versatile, which can be used to handle lifts with small and large capacity.

With no limiting capacity, the top running crane can be used to handle lifts with small capacities to very large capacities. Top running cranes consist a rail installed on top of each runway, with wheels move on the rail, rather than on the bottom flange of the runway beam. Supported by the building structure or runway support columns, or sister columns, top running overhead travelling crane are the first option for moving extremely heavy loads.

Overhead travelling under running crane / Underhung crane

Under running crane, also called under hung cranes, are used for lighter service and lower capacity applications, usually supported by ceiling or roof structures.

Due to the crane wheels are supported by the bottom flange of the overhead travelling crane runway beams, functioned as the crane rail, the under running crane is also called under hung cranes. This type of overhead travelling cranes can maximize the utilization of the floor space of your facility, because under running cranes are supported by the ceiling trusses or the roof structure.

With the utilization of an existing support structure (if adequate), or run on a newly-engineered support structure, the under running cranes may lower the cost of crane.
