Columbia hoisting systems
Hammerhead Trolleys
A light trolley that rides the beam while a base-mounted Columbia hoist stays put. Two-part reeving through the trolley and load block doubles the hoist’s capacity, and the hook height doesn’t change as the trolley travels.
Why a hammerhead instead of an overhead hoist
The hoist is base-mounted off the beam, so the trolley carries only its own light weight. That leaves more of the beam’s rating for the load: a higher net hook load than a conventional overhead hoist on the same beam.
Because the hoist never moves, there is no electrical festooning to run along the beam and the controls don’t have to follow the load. The wire rope is reeved through the trolley and load block, which doubles the hoist’s capacity, and moving the trolley doesn’t raise or lower the hook.
The compact frame gives more hook height, which matters in low-headroom areas, and low-friction bearings make the trolley easy to move.
How the system works
- Base-mounted Columbia hoist stays fixed
- Rope runs out along the beam to the trolley
- Down through the load block and back up to the trolley: two parts of line
- Trolley travels by hand chain or power drive
- Hook height stays the same anywhere along the beam
