Hook Centering

Centering improves safety, prevents damage

Side pulling puts added stress on ropes and other crane components and sets the stage for hazardous load swing. But the Konecranes Hook Centering feature automatically eliminates side pull of loads and this dangerous scenario, helping to prevent equipment damage and harm to employees.

Hook Centering is based on measurement of the rope angle. If the angle exceeds a preset value when the hoist starts to lift a load, Hook Centering activates.

Once turned on, protection is constant

Side pull occurs when a hoist lifts a load that is not placed directly underneath it. Side pull causes extra stress on different crane components such as the wire rope, rope guide and drum. It can also cause uncontrollable movements of the load, which is a safety hazard for the surrounding area.

The crane operator turns on Hook Centering with the selector switch on the radio controller. After that, the feature is always on in every lifting situation.

Once the hook or lifting device has been connected to the load, the crane operator starts the lifting operation. If side pull is detected, Hook Centering activates.

Lift delayed until load centered

While the crane operator continues with the hoist-up command, the crane automatically positions its trolley and bridge over the load.

At the same time, movement upwards is limited. When the crane and load are vertically aligned, lifting continues normally.

Hook Centering means improved operational safety, faster load cycle times, ease of operation and less wear and tear on crane components.
