Technical description 2.1 Boom frame and pedant plate The is lattice structure made by imported high strength steel pipe, and the pedant plate by imported high strength steel plate. length : 20~83m adjustable added section length: 3m 6m 9m fixed jib 12~30m: fixed jib length fixed jib adjustable added length:6m Max. length of + fixed jib: 71+30m tower jib tower jib length:27~51m tower jib adjustable added jib section length Max. length of + tower jib:59+51m 2.2 Mechanism Main & auxiliary hoisting mechanism It includes axial inner plunger hydraulic motor, balance valve, reducer, normally-closed brake, clutch, wire rope, etc.. It can be controlled separately. Wire rope is the special anti-torsion wire rope imported from German. When there is four layers wire rope on the roller, Max. single wire rope speed of the hoisting main winch and auxiliary winch reach 48m/min. Main & auxiliary mechanism is double speed type and has two lifting speeds, which can increase working efficiency. Derricking mechanism It includes axial inner plunger hydraulic motor, balance valve, reducer, normally-closed brake, clutch, wire rope, etc.. It can be controlled separately. Wire rope is the special anti-torsion wire rope imported from German. Derricking mechanism has ratchet self lock protection mechanism which can prevent derricking winch hook from sliding because of long time parking. When there are four layers wire rope on the roller, Max. single wire rope speed of the derricking winch reaches 48m/min. Slewing mechanism It includes axial inner plunger hydraulic motor, gear reducer, slewing brake valve, brake, pinion and slewing ring, etc., and it drives the slewing ring to realize full slewing - 5 -

6 through the pinion, also realize the slewing function of the superstructure. It adopts sliding control which ensures small impact and stability during brake starting. It adopts outer mesh slewing ring with three column rollers and slewing reducer which have strong bearing capacity and high accuracy, thus can ensure stable, accurate slewing. It can realize 0~1.39r/min stepless speed adjustment. It can be locked by two mechanical lock devices in front of the slewing table. Travelling mechanism It adopts double motor, double reducer type. Hydraulic motors and travelling reducer are all imported. The travelling of two tracks are controlled by two sets of control levers. The travelling mechanism can realize straight line travelling, single side steering, differential steering, steering in the same place, travelling with load, etc, which have high mobility and flexibility. travelling speed:0.6~0.98km/h gradeability:30% track tension: control by hydraulic jack, it is rapid, convenient and reliable. Mast jack mechanism It includes mast, mast jack cylinder and auxiliary hydraulic system, etc.. When assembling or disassembling( or change work site ), let the mast 90 with the horizontal position to connect pendant plate, assemble frame, track assy and the counterweight. Operator s cab rotation and pitch mechanism The operator s cab can rotate 90 from the side to the front and is fixed by the position pin to decrease width of the whole vehicle and is convenient for transportation. The pitch of the operator s cab is controlled by the cylinder. When the lifting height is high, the operator s cab can be pitched 20 upward which is convenient for transportation. Counterweight and its self assembling & disassembling mechanism It includes the counterweight bottom plate, the counterweight, the counterweight jack cylinder, bearing chain and fixed pin cylinder. The counterweight can be assembled / disassembled by the crane itself, thus can increase utility of the crane and decrease installation danger. Outrigger jack and track self assembling & disassembling mechanism It includes chassis outrigger, outrigger cylinder, outrigger valve, track power pin, etc.. The outrigger jack mechanism is the main bearing mechanism. The track self assembling mechanism lifts the track assy by mast and mast jack mechanism, and connects the frame and track assy by power pin. It can assemble / disassemble the - 6 -

7 track assy without auxiliary lifting equipment, which can increase working efficiency and decrease labor intensity. The power pin can avoid danger by manual control. 2.3 System Hydraulic system It includes main pump, control valve, hydraulic motor, hydraulic oil tank, cooler, etc.. It adopts world advanced pump control system, main parts, e.g., pump, motor, control circuit and main circuit valve, are imported from German, which are with high efficiency, energy saving, high reliability and long lifetime. Main hydraulic pump: double variable plunger pump with serials gear pump, driven by the engine Auxiliary mechanism oil source : gear pump Main control valve: pilot electro-hydraulic control valve Main circuit control way: variable main pump + main change valve are all controlled by the lever. Hydraulic oil tank capacity:700l Cooler: AL radiator, with electric drive fan Electric system 24v DC, negative ground, two 195 AH batteries The whole vehicle electric mainly includes power, engine starting, engine extinguishing, indicator, alarm, illumination, fan, wiper, horn, lifting height limit, hydraulic oil cooling fan, digital monitor, PLC controller, engine pre-heat device, safety device, etc., which ensure safe working and good working environment for the crane. The whole vehicle adopts CAN bus that can connect engine, PLC controller and digital display together effectively, and also has trouble detection and automatic diagnosis function. Power system Original imported VOLVO electronic injection diesel engine with CAN bus interface Rated output power: 256kw,2100r/min Max. output torque: 1750Nm,1200r/min Displacement standard: U.S. EPA Tier 2 and EU Stage II Fuel tank adopts 700l oil tank to ensure enough working time for the engine. Concentration display system 10.4 inch big screen LCD monitor with several language monitor can display all kinds of working condition signals collected by PLC controller, includes engine rotation speed, water temperature, fuel pressure, hydraulic pump pressure, pressure of main motors, working condition of main machine, etc.. The monitor can control the - 7 -

8 working condition in real time, the system can send yellow warning or red warning when abnormal condition occurs during operation. Central lubrication system Adopt German imported central lubrication system that is convenient for the maintenance and can decrease worn of the parts. 2.4 Safety device Moment limiter It includes torque monitor and digital LCD monitor. When single lifting torque reaches 90% of rated torque, the buzzer sounds. The operation of the crane stops automatically when the torque reaches the rated value to prevent the crawler crane from accident because of overloading during construction, which can ensure normal and safe operation of the crane. Following data can be displayed in the digital LCD monitor. torque ratio elevation angle length working radius actual hook load permissible lifting load Max. permissible lifting height wind speed at the top of the frame Overflow valve in the hydraulic system It can prevent abnormal high pressure in the circuit to avoid damage of the hydraulic oil pump and the motor, also can prevent the system from overloading condition. Wire rope overwinding & overlowering protection device height limit device angle indicator working limit position warning protection system whole vehicle horizontal sensor Hook lock device Derricking winch ratchet lock mechanism wind meter 2.5 Operator s cab The operator cab adopts full steel structure with toughened glass on four sides; top glass and front window glass have two layers. Inside, there are right ante-vanna, adjustable seats, wiper, electric control lever, moment monitor, digital display, all kinds of switch auxiliary remote control box assy, air conditioner, fan, illuminator, radio cassette ( CD player, mps player, vehicle DVD for option ), cigarette igniter, - 8 -

9 extinguisher, etc.. The operator s cab is with wide vision and big space. 2.6 Hook All are fitted with rotation hook and hook lock device. 200t main hook ( option ): with 8 pulleys 130t hook: with 4 pulleys 65t hook: with 2 pulleys 30t hook: with 2 pulleys 16t hook: with 1 pulley - 9 -
