TYPES OF CRANE

OVERHEAD TRAVELLING CRANES (OHTC)

This type of crane runs on an elevated runway system along the length of a chosen area and provides three axes of hook motion. They are generally offered in a single girder or double girder design – double girder cranes give the advantage of providing more height of lift when headroom is tight and generally used for longer span cranes. Both single and double girder bridge designs are provided with great flexibility in allowing the hook to be positioned very precisely and for loads to be placed very gently.

GOLIATH CRANES (GANTRY CRANES)

This type of crane is quite similar to the Overhead Travelling Crane except that it runs on a track at floor level. The bridge (which carries the hoist and trolley) is supported by a pair of rigid steel legs which, in turn, are carried by a pair of end trucks along the floor-level runway. The Goliath Crane provides the same performance characteristics that an Overhead Travelling Crane offers. It is also possible to have one side of the bridge supported on a runway system making it a Semi-Goliath Crane.

 

MONORAIL (RUNWAY)

This type of overhead lifting system is quite specialized and very effective when properly designed into the factory layout. Only two directions of hook travel are afforded by the monorail: up/down and along the axis of the monorail beam. It is not recommended (and quite dangerous) to push the load out from under the centerline of the monorail beam. The key phrase here is "when properly designed into the factory layout" since monorail systems, by their nature, are most often integrated into continuous production systems for material transport; e.g., hot metal operations in a foundry, paint booths, etc. Monorail cranes are available as straight line runways or with junctions and bends and can be fitted with electric chain hoists to suit your application.
