Double Truss Single Bridge Cranes

Main Girder :- Bigger cross section of of industrial bridge fabricated from less quantity of steel resulting in an economical design. Lightweight double girder bridge with additional support to reduce stress on building supports. Maximum lift with lower head room. Easy maintenance. Bigger cross-section for stability and low vibrations in girder. Cross Travel Drive :-The motor driven trolley perfectly coupled with hoist increases the speed and efficiency of the load handling. Protective steel plate frame extend beyond wheels for the end contact. Wheels have contoured tread for smooth movement over standard tapered or wide flange flat beams. The traverse gear reducer has are provided with output pinion meshing with machine cut wheel gears.Long Travel Drive :- The double girder cranes are made from a combination of solid shafts and floating shafts connected by universal couplings and supported on pedestals blocks. This arrangement is driven by crane duty foot mounted motor transmitting torque to heavy duty shaft mounted gear box, which transmits torque to output pinion that meshes with machine cut wheel gears. The special rail sweep and crab frames removes the object left on the track. Rubbers Buffers are also provided with end-carriages & crab in the industrial double girder cranes. A special Soft Start Unit coupled to the LT drive provide exceptional control over the speed of the motor along with smooth start.
