Our Crab Hoist solutions are suitable for manufacturing plants, steel industries, engineering units, fabrication facilities, foundries, warehouses, automobile industries, power plants, heavy machinery manufacturing, and other industrial material-handling applications.
What Is a Crab Hoist?
A Crab Hoist is a crane hoisting and trolley arrangement designed to lift, lower, and move loads horizontally across the crane bridge.
The term “crab” commonly refers to the trolley assembly carrying the hoisting mechanism. The crab travels along the crane girders, while the crane bridge itself travels longitudinally along the runway.
This creates three primary crane movements:
- Hoisting: Vertical lifting and lowering of the load
- Cross Travel: Movement of the crab/trolley across the bridge
- Long Travel: Movement of the complete crane bridge along the runway
This arrangement is particularly useful for heavy-duty overhead cranes where precise positioning and substantial lifting capacity are required.
How Does a Crab Hoist Work?
A Crab Hoist operates through coordinated mechanical and electrical systems.
1. Hoisting Mechanism
The electric hoisting mechanism raises and lowers the load using a wire rope, drum, hook block, and associated components.
2. Crab/Trolley Travel
The crab travels along the crane bridge using powered wheels and a suitable travel drive.
3. Crane Bridge Travel
The complete crane bridge moves along runway rails using the crane long-travel mechanism.
4. Load Positioning
The combination of hoisting, cross travel, and long travel enables operators to position loads within the crane's designated working area.
A typical movement sequence can be represented as:
Hoist
Vertical Movement
Crab
Cross Travel
Crane Bridge
Long Travel
