Product Description

 

Product Description

When heavy loads and wide spans are required, the overhead cranes show their strength. They consist of two torsion-free box girders. This makes them especially suitable for lifting and transporting loads over 50T and for span of more than 35m. 
Overhead cranes are available with load capacities up to 50T and with spans up to 35 m. Articulated end carriage joints ensure positive contact of all four wheels with
the track. The range of fixing arrangements allows the appropriate integration of double girder travelling cranes into new buildings as well as into existing buildings.
Just aswith all other types ofdoublegirder travelling cranes, the profiles of the main girder are optimally produced using computers so that maximum performance with a minimum of dead-weight can be achieved. An advantage that has financial benefits.

 

Use scope

1. Light duty cranes for repair shops, light assembly operations, service buildings, light warehouses, where service requirements are infrequent. 
2. Medium duty cranes for machine shops and general industrial use both indoor and outdoor application. 
3. Extra heavy duty cranes for steel mills and other heavy machine shops, steel warehouses, heavy fabrication shops, paper mills etc. With magnet and bucket
operation for scrap yards, fertilizer plants & induction furnace. 
4. Extra heavy duty cranes for steel mills and other heavy engineering purposes. Cranes designed for hot metal application on request.
