High Speed Extension
The High Speed Extension is a standard feature on PALFINGER loader cranes. Also referred to as Return Oil Utilization, this feature is a regenerative hydraulic circuit for the extension booms. It speeds up the boom extend and retract functions by up to 30%.
Single Link
The knuckle joint significantly improves the crane’s motion geometry.
