Left-hand steering wheel is adjustable for height and inclination.

2.8 Hydraulic system

Variable displacement pump connected to engine through transmission and PTO provides hydraulic power for lifting operation.

Manual multi-way change valve controlling the moving directions of outrigger beams and jacks can be operated on each side of the vehicle. The change valve adding a pressure valve efficiently prevents the piston rods of horizontal cylinder bending.Speeders equipped on outrigger jacks (double-way hydraulic valve on 5th jack) not only prevent retracting of the piston rods of jack cylinder during lifting operation, but also improve the speed for outrigger extending/retracting.

2.9 Hydraulic outriggers

4 hydraulic outriggers can be hydraulically operated. There is a control console on each side of the carrier respectively. Levels for leveling the vehicle are available. The outrigger floats are stowed under the jacks. Outriggers are designed to raise the vehicle for operations in all kinds of working condition.

5th outrigger jack: located under the front of the vehicle frame for 360º operation of the boom.

2.10 Electrical equipment

24V DC, negative ground, 2 batteries. Lighting device comprises of front headlamp, fog light and reversing light etc., complied to the relative regulations in China National Standard.

2.11 Tool

A set of maintenance tool is available.

3. Crane Superstructure

3.1 Slewing mechanism

The roller Slewing Bearing as connection of the carrier and the crane superstructure can rotate 360º continuously. The roller bed is sealed to resist water and dust.

3.2 Turntable

Designed and manufactured by XCMG, equivalent stress and tapered cross-section box-type structure, made of high-tension steel.

3.3 Hydraulic system

The vehicle power is transferred by hydraulic system of combination 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.

Superstructure hydraulic system adopts pilot electro hydraulic proportional control and has function of load-feedback. The main control valve is advanced load sensitive type proportional multi-way change valve.

The pressure difference between pump outlet pressure and load pressure can change variable pump inclination of oil distributor through load feedback port, thus changing the flow of the pump. With the control of constant power variable displacement pump, the pressure and flow of the pump can be adjusted well by load feedback, thus greatly increasing control performance and energy-save effect. The pilot control valve uses an imported electro hydraulic proportional valve. The moving angle of its handle is directly proportional to the input current, so does the movement of the main control valve element. Thus the whole machine has good fine motion control.

Hydraulic oil tank capacity: approx. 600 L

3.4Control

Conventional control is carried out by 2 self-centering 4-way joysticks in the carrier cab. All movements of the crane are controlled by pilot control through hydraulic pump and proportional valve, stepless speed variation is available.

3.5 Main winch

Main winch is controlled by open oil circuit. Variable-displacement motor, compact and high performance professionally made planetary gear reducer with wet brake, drum with special rope groove and rotation resistance wire rope are available.

Wire rope diameter: 20mm

Wire rope length: approx.185m

Max. single line speed: approx. 130m/min.

3.7 Auxiliary winch:

Auxiliary winch is controlled by open oil circuit. Variable-displacement motor, compact and high performance professionally made planetary gear reducer with wet brake, drum with special rope groove and rotation resistance wire rope are available.

Wire rope diameter: 18mm

Wire rope length: approx.125m

Max. single line speed: approx. 108m/min.

3.8 Elevating system

Boom elevation is driven by one differential cylinder with a balancing valve.

Elevating angle: -2º~ 78º

Elevating time: approx.60s..
