Frame

Designed and manufactured by XCMG; Full- covered walking platform, made of high-strength steel

Outrigger

4 outriggers, H-typed arrangement, lateral swing movement and jacks are controlled hydraulically. A check valve is fitted at each outrigger oil cylinder, and each jack is fitted with a double-way hydraulic valve for ensuring operation safety. There are two auxiliary jacks for helping self-mounting of front outrigger beams.

There is an electrical control station installed at each side of chassis. Luminous level gauge, illuminating lamp and acceleration button are equipped on each control station.

Outrigger span: Longitudinal x lateral (fully- extended) 5.23m x 6.16m

Dimension of outrigger float (p340mm

Outrigger reaction force at max. lifting capacity...31t

Hydraulic system

Exclusive matching throttle with compensation afterwards and load-sensitive technology results in the higher stability of the lowest system flow, more reasonable system rigidity, more outstanding fine control and smoothness. With double-pump confluence of hoisting, elevating and telescoping, the working speed of main and auxiliary winch can reach 135m/min, which improves the efficiency greatly. The distribution of flow in actuators is more optimized when conducting compound movements and the working efficiency is more outstanding.

Operator's cab

Ergonomic cab design, with swing-out doors, safety glass, sun visor, adjustable seatsand protective rails equipped. Fan is standard and air-conditioner is optional.

Brakes

Double circuit, air braking, drum brake.Service brake: double-circuit air pressure brake, acting on all wheels.

Parking brake: spring energy brake, acting on wheels of 2-3 axles.Auxiliary brake: engine retarded brake, engine exhaust brake, safe and reliable, which prolongs the service life of brake friction disc.Auxiliary brake: engine retarded brake, engine exhaust brake, safe and reliable, which prolongs the service Life of brake friction disc.

Safety devices

Hydraulic counterbalance valve;

Hydraulic relief valve; Double-way hydraulic valve;LMI; Spring return system of control levers;Lowering limiter for preventing wire rope from over-releasing;Anti-two block at boom head for preventing wire rope from over-winding.

Steering

Mechanical steering system with hydraulic boost.

Fixed counterweight

Total weight of 3.2t.

Driver's Cab

Equipped with four-point connecting structure, the new full driver's cab of steel has open car doors on both sides. The main drivers can adjust height automatically. With double seats, the passenger's seats can be used as simple sleeper for temporary rest of drivers. Safe glass with electric lift contributes to good heat-proof effect. Automatically adjustable rearview mirror is safe and convenient The steering wheel can adjust the height and angle, which is suitable for operators of different heights.

LCD, bus control, centralized information

show; and the layout of center console

with new combination is safe and

reasonable which adopts arc design and represents humanization. Fixed wiring harness connector save the space of driver's cab with fixed plug-in components. Integrated central distribution box enhances the reliability

of electric system in driver's cab. The

application of PLC control system

improves the stability of chassis electric

 and die efficiency of error self-diagnosis.

It is equipped with Standard  CD player

and air-conditioner both for cooling and

heating.
