QY65K Truck Crane

الوصف

The vehicle is driven by hydraulic system of open type variable displacement and constant displacement. The main winch system with variable displacement pump and motor has constant power and can get lower speed with heavy load, higher speed with light load. The hydraulic valve block of integrated and modular design with imported pipe connectors, less of hydraulic pressure, high efficiency and good reliability. 2. Main and auxiliary winches, both with planetary reducers arranged in drum, compact structure and good arrangement and high efficiency, can be operated independently. 3. Slewing mechanism, with planetary gear reducer and instant closed brake, slant tooth three-row rolling slewing bearing driven by motor, has the function of controllable free-slide and smooth inching with buffer valves equipped in hydraulic system. 4. Equipped with perfect safety devices: automatic moment limiter (AML), height limiter, rope-end limiter, outrigger inserted pins and level gauge. Illuminators facility night operations. 5. Boom of round angle hexagonal cross-section optimized and imported WELDOX **0 steel plates improve the lifting capacity greatly. 6. Electro-hydraulic proportional control for superstructure makes operation comfortable and convenient and better inching control function. 7. Spacious and bright cabs for driver and operator equipped with adjustable seats, comfortable for operation, heater and air conditioner are for option. 8. Lower center of gravity, good stability and maneuverability, faster travel speed, suitable for rapid work-side transfer.
