1. 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
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 960 steel plates improve the lifting
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
