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:

1. The New single girder cranes needed to have the same amount of lift as the old double girder cranes

2. New cranes could not have any painted surfaces that could chip or flake (Note: clean room environment)

3. Precise hook spotting required for accurate hood positioning

Our Team Approach:

1. Our team, armed with existing building dimensions, designed a stooled up single girder crane with a close headroom hoist to meet the lift requirements.

2. 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.

3. 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.
