The Liftco Side Pull Preventer is a cost-effective safety device for cranes and hoists.
If the unit detects any angular deflection in the lift chain or rope that might indicate that the load has become snagged or trapped, it cuts power to both the lifting and travel circuits.
The unit can be fitted to any multi-fall crane or hoist, either on fixed or moving rope. It is very compact and is normally fitted above the moving range of the bottom block, and so does not interfere with the range of the lift.
After the unit has been tripped, it is reset simply by lowering the hook or moving the crane directly over the load.
