Detailed Product Description
Double Girder Overhead Crane With Electric Wire Rope Hoist For Repair Workshop / Warehouse For Indoor /
Outdoor
Description:
Double girder overhead industrial crane is characterized by strong bearing, big span, and overall stability with
various models, but their quality is better compared with single girder gantry crane with the same capacity. They
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 as with
all other types of double girder 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.
Double girder overhead crane with hoist are widely used in the following applications:
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.
