Eliminate Problems Related To Torque!
- Hydraulically operated mechanical spotter arm may be attached between the device body and the pile lead.
- Electronic position sensors on the spotter arm measure angular relationships between the pile lead and the spotter arm.
- Position sensors on a boom box on the boom may also be used.
When the pile lead is swung, information from the sensors may be used by an electronic control system to automatically maintain the pile lead in a desirable position, limiting torque induced in the boom. The boom box position sensors may be used to counter-steer the spotter arm to further limit torque.
