Main and Aux. Load Hoist Mechanism
Pump and motor: energy-efficient, combination of winch balance valve and anti-hook sliding technology, lifting or lowering the load steadily; Winch brake adopts wet type and spring loaded fin type normally engaged brake, spring force braking, oil pressure released; Main and aux. load hoist winches adopt piston motor of fixed displacement to drive planetary reducer.
Boom Hoist Mechanism
Double acting single piston rod hydraulic cylinder, fitted with safety balance valve, luffing angle: -2°~78°, adopting deadweight luffing system to reduce the energy consumption and improve the steadiness of luffing operation.
