Down with the OLD, Up with the NEW

 

 

 

The Challenge:

Remove two old 10 Ton Top running double girder cranes and replace them with two new 10 ton top running single girder cranes.

 

 

 

 

 

 

Special Considerations:

  • The New single girder cranes needed to have the same amount of lift as the old double girder cranes
  • New cranes could not have any painted surfaces that could chip or flake (Note: clean room environment)
  • Precise hook spotting required for accurate hood positioning

 

Our Team Approach:

  • Our team, armed with existing building dimensions, designed a stooled up single girder crane with a close headroom hoist to meet the lift requirements.
  • The hook and lower block of the hoist were disassembled, sand blasted, and reassembled.  The running surfaces on the bridge beam were kept bare metal.
  • A four light state of the art hook positioning system was installed on the hoist to indicate the exact lifting point

Result:
The old cranes were removed and the new cranes installed with little to no interference to the customer production time.
