Crane designs: Overhead crane, Eot overhead travelling crane , Bridge crane

13 Sep, 2018

As one of the top electric overhead travelling crane manufacturers and suppliers, Dongqi Crane offers different types of eot overhead cranes, crane hoists, and related crane parts, etc. Dongqi Crane offers general material handling eot cranes, and custom industrial cranes with unique crane designs which goes well with your lifting requirements, working application, and crane purchasing budget.

Main overhead crane designs

Generally, bridge cranes mainly has the following overhead crane designs, including single girder crane design, double girder crane design, top running design and underhung design, etc. The various custom crane designs are based on the main crane designs.

Single girder overhead crane

A single girder bridge crane is usually designed for the lifts under 20 tons, span less than 31.5m, or the requirement for crane services classification is under A7 and A8.

The overhead bridge consists of one girder beam supported on each side by an end truck. The electric trolley and hoist commonly run on the bottom flange of the bridge, often called single girder underhung overhead crane. The single girder underhung crane is less expensive because of the following reasons:

  • Only one beam girder is needed to move the trolley and hoist
  • Lower cost in freight.
  • Easy installation
  • Hoist and trolley design is easier than those of double girder bridge overhead crane.

Double girder bridge overhead crane

When the lifts is more than 20 ton or the span is more than 31.5m, or the crane duty cycle is A7 and A8, the double girder bridge overhead crane will be the first choice.

Two girder beams makes up the bridge, supported by an end truck or carriage on each side, with the electric trolley and hoist running on the rails, installed on the top of both bridge girders.

  • Double girder cranes are recommended for heavier-duty applications, where lifts is more than 20 ton or the span is more than 31.5m, or the crane duty cycle is A7 and A8.
  • Double girder crane is selected when crane needs to be custom designed, in terms of walk ways, driver’s cabs, magnet cable reels, and others.
  • What more, double girder crane offers more lifting height with the top running design.

Top running overhead crane vs. Underhung overhead crane

What a top running crane or under running crane is should be understand when you want to know the clear differences between bridge cranes.

  • On a top running crane, the beam bridge runs on rails along the top of the runway beams.
  • On an under running crane, or underhung crane, the beam bridges are supported by the bottom of the runway beams and the crane wheels run along the bottom of the lower beam flange.

Top running crane

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

Top running crane - Type of overhead crane

With no limiting capacity, the top running overhead crane can be used to handle lifts with small capacities to very large capacities. Top running bridge 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 crane are the first option for moving extremely heavy loads.

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.

Under running or under hung crane - Overhead crane type

Under running or under hung crane - Overhead crane type

Due to the crane wheels are supported by the bottom flange of the overhead crane runway beams, functioned as the crane rail, the under running crane is also called under hung cranes. This type of overhead 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.

Features of underhung cranes

  • Designed for lighter service / lower capacity applications.
  • Maximize utilization of the building’s width and height when supported by roof or ceiling structures.
  • Hook height is less than top running design because the bridge of overhead crane and electric hoist hang underneath runways.
