Main parts introduction of chassis |
1. | Frame Designed and manufactured by XCMG, the frame is made of high strength steel with fully covered walking surface and anti-torsion box-typed structure. |
2. | Outriggers Four outriggers, arranged in H-shape are hydraulically controlled by control levers. There are two outrigger control stations located at each side of the chassis, and there are two level gauges on each control station. The outrigger movements can be simultaneously or separately controlled on either side of the chassis. A 5th jack is equipped. There is a double-way hydraulic valve fitted in each jack cylinder. Outrigger float diameter: φ400 mm Reaction force of outrigger at maximum lifting capacity: 356KN |
3. | Engine SC9DF290.1Q6, in-line, 6-cylinder, water cooled, electric control diesel engine is made by Shanghai Diesel Engine, with rated power of 214kW/2200 rpm and maximum torque of 1270Nm/1200~1500 rpm. Maximum reference torque: 1557N.m; Compliant with China VI emission standard; Fuel tank capacity: 360 L AdBlue/DEF tank capacity: 35 L. |
4. | Motor (Plug-in version) TZ238XSXG60A Weiteli permanent magnet synchronous motor Motor power: 60/110 kW; Motor torque: 380/800 N·m; External power supply voltage (AC): 380 V. |
5. | Transmission 9-speed FAST Transmission with synchronizer; mechanical control. |
6. | Axles High strength axles; 2nd and 3rd axles are for driving. |
7. | Suspension Front suspension: longitudinal leaf spring balanced suspension, with cylindrical shock absorber. Rear suspension: rubber suspension, light dead weight and maintenance-free. |
8. | Tires 10 tires and 1 spare tire. Single tire installed on the front axle, double-tire installed on the middle and rear axles. Tire specifications: 315/80R22.5 (axle 1). 12R22.5 (axles 2 and 3) |
9. | Steering Mechanically steering mechanism with a hydraulic booster. |
10. | Braking system Service brake: dual-circuit air pressure brake acting on all wheels. Parking brake: spring-applied brake, acting on wheels of axles 2-3. Auxiliary brake: engine exhaust brake. |
11. | Driver's cab Full-dimension driver's cab, 2-man design. It is equipped with adjustable seats, steering wheel, safety glass, 3 wipers, electrically operated door window lifters, glove box and air conditioning. |
12. | Electrical system 24V DC, two sets of 12V battery in series. Generator: 28 V-70 A. |
Main parts of superstructure |
1. | Structure Designed and manufactured by XCMG, made of high strength steel. |
2. | Hydraulic system Constant gear pump driven by chassis engine, used for hoisting, luffing and telescoping operations. Load-sensing proportional directional valve with impact resistance valve and cavitation-proof valve integrated; air-cooled hydraulic oil cooler. Tank capacity: 600 L |
3. | Control system Pilot hydraulic control is used for controlling the superstructure. All crane movements are controlled by hydraulic pump and proportional valve through two control levers at left and right sides. |
4. | Winch system Drum with Lebus grooves, driven by a hydraulic motor, with build-in planetary gear reducer, constant closed brake and counterbalance valve. Wire rope has a rope head, which is directly installed in pouch socket. Time for replacing wire rope is shortened, the replacement is easy and fast. The main winch and auxiliary winch can be independently operated. |
