Power Dolly

Our power dollies have a drive system capable of limited slip on the rear axle. This means that if one wheel is in slippery conditions, then the drive will engage the other wheel on the axle and continue forward movement of the dolly and load. The engagement of the limited slip is automatic. The point at which the limited slip activates can be adjusted by changing the orifice size on the drive. It is not necessary to set a switch. When the limited slip is not required, then the drive runs without engaging. The limited slip feature allows for easier steering than with posi-traction.

All Holland Power Dollies feature a safety holding valve that automatically closes if a drive hose breaks. This action takes place faster than the operator can react manually and prevents a run-away condition. The manifold also has a pressure relief valve on the case drain to protect the case seals of the hydraulic motor. The relief valve will prevent accidental case over pressurization and costly down time.

Benefits:

• Handle larger loads with a smaller footprint
• Walk along while controlling the transport system
• Safest – Holding Valve Protection prevents run-away equipment
• Easily change from hydraulically driven to a faster freewheel mode
