Technical specifications | |||||
Structural members | Made of high strength fine grained steel, welded torsion-resistant frame type construction with large cross-section, high load-bearing capacity. | Boom | I basic boom and 4-telescoping sections, quadrilateral cross section welding structure. Double-cylinder plus ropes telescoping mechanism is for synchronous plus sequential telescoping. 8 pulleys on boom head are standard. Boom length: 12.4m ~ 48m. | ||
Outriggers | 4 outriggers, H-shape arranged, which are located at both sides of chassis frame, controlled by hydraulic valves and the cylinders are controlled by electric signals. Front and rear towing eyes are available. | Jib | 2-section,lattice and box welding structure, with three jib off set angles of 0° ,20° and 40° available. Jib length: 11.7m 〜20.6m. | ||
Engine | QSL, in line six-cylinder water-cooled compression ignition diesel engine, manufactured by Cummins, US, rated power is 224 kW/2100rpm, max. torque is 1369Nm/ 1300〜1500rpm, offroad U.S. EPATier 3/EU Stage IIIA emission standards. Fuel tank capacity： Approx. 300L. | Operator's cab | Integrated design, appearance is simple and artistic. It is all-weather and equipped with large arc glass, which has a wide vision, as well as spacious and comfortable due to ergonomic inner design. Equipped with air conditioner. | ||
Hydraulic system | The constant power variable displacement pump is used for controlling the movements of crane. Oil tank capacity: Approx. 1250L. | Safety devices | Hydraulic balance valve, hydraulic relief valve, hydraulic double-way valve and LML Lowering limiter is equipped in winch to prevent rope over-releasing. Anti-two block is fitted on the boom head to prevent rope over winding. | ||
Operating mode | Electric controlled pilot operation system is equipped with two electric proportional control levers controlling the main movements of the crane. | Counter weight | Total weight is 5t, fixed counterweight, | ||
Transmission | 6WG260, German ZF automatic transmission. | Electrical system | DC 24 V, two batteries in series. | ||
Axles | German KESSLER axles with great load bearing capacity. Both front and rear axles are drive axles for steering. | Hook block | 70t hook block,4 sheaves,single hook | ||
Suspensions | Front axle is rigidly connected to the frame. The rear axle is attached to the swing-type hydraulic suspension, which may be rigidly locked. During highway driving operation, shock absorption function is activated, which buffers the road shock. When driving with a suspended load, rear suspension cylinder is locked to rigid state to meet operation requirements. | Additional equipment | |||
Tires | 4 tires, each axle is equipped with single tire, load bearing capacity is great. Tire specifications: 33.25 R29. | Air conditioner | Equipped in the cab, for improving comfortable performance. | ||
Steering | Full hydraulic electro-proportional multi mode steering: front axle independent steering mode, tight-turning radius mode, crab walk mode and rear axle independent steering mode. | Hook block | 120t hook block,8 sheaves,double hook. 25t hook block,2sheaves,single hook.7thook block,single hook. | ||
Brakes | Service brake: double-circuit full-hydraulic disc brake, acting on all wheels. Self braking works in case the pressure in the braking system becomes too low. Parking brake: spring-loaded, hydraulic- released independent disc brake, acting on the front axle. | Differential locks | With these differential locks fitted, pass ability may be improved in case of slipping when driving on difficult roads or single-side tires slipping due to partly suspended drive wheels. | ||
Main winch system | Driven by a hydraulic motor, with build-in planetary gear reducer, constant closed brake and rotation resistant wire rope equipped, having features of high speed with light load and low speed with heavy load. | Auxiliary which system | Driven by a hydraulic motor, with build-in planetary gear reducer, constant closed brake and anti-coiling wire rope equipped. | ||
Slewing system | Single-row, four-point contact-ball slewing bearing, driven by hydraulic motor, with built- in planetary gear reducer and constant-closed brake equipped, and may continuously slew 360° . | Product parts list is as mentioned above, please refer to the product quotation for specific parts. | |||
