Lashing eye with indication of a pulling force Towing hook without indication of a pulling force

The indicated values are valid only when the pulling forces are applied in the middle axis of the hooks or of the eyes.

Caution! Take care to never exceed the maximum possible pulling force. Going across the allowed pulling force could cause the destruction of the hooks or eyes, of their welding joints and / or of the surrounding undercarriage structure ! When towing another machine or emergency towing the excavator, only employ proven towing and pulling devices presenting a sufficient rated traction force considering the pulling forces which may arise during the towing operation. Danger! Never allow anyone to stand near the cable when the excavator is towed! There is a danger of injury due to a torn rope. Start travelling with care so to tension the steel cables and other lashing devices slowly and progressively. Applying the tension too brutally to a sagging cable can cause the cable to rupture. During the whole towing operation keep the steel cable tensioned and free of kinks.

Emergency towing of the excavator The machine may only be towed in exceptional circumstances, eg. in order to move the machine away from a dangerous place for repair. The admissible traction force of the hooks 3 and lashing eyes installed to the undercarriage is in general insufficient to permit the emergency towing of the machine.
