RT120U Rough Terrain Crane
1、Specialized energy-saving hydraulic system.
2、Due to powerful power configuration, specific off-road tires and all-wheel drive, the crane can easily handle various tough terrains.
3、The crane is designed by conforming with the safety standards of Europe, North America and China, for optimal active protection.
4、Developed jointly by Chinese and German engineers, with advanced design concept.
5、Accumulation of experience in boom crane design for 70 years.
6、Top class modern plate machining center, and first class NC machining center.
Made of high strength fine grained steel, welded torsion-resistant frame type construction with large cross-section, high load-bearing capacity.
1 base boom and 4 telescoping boom 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:40.67ft ~ 157.44ft
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.
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.
QSL, in line six-cylinder water-cooled compression ignition diesel engine, manufactured by Cummins, US, rated power is 300bhp/2100rpm, max. torque is 1010ft lb/1300 ~ 1500rpm, offroad U.S. EPA Tier 3/EU Stage IIIA emission standards.
Fuel tank capacity： Approx. 79.2gal.
Hydraulic balanced valve, hydraulic relief valve,
hydraulic double-way valve. Lowering limiter is equipped in winch to prevent rope overreleasing. Anti-two block is fitted on the boom head to prevent rope over-winding.
The constant power variable displacement pump is used for controlling the movements of crane.
Oil tank capacity: Approx. 330gaL
Self-assembly counterweight is 396831b. Four combinations of 01bx 132281b、264551b and 396831b are available.
Electric controlled pilot operation system is equipped with two electric proportional control levers controlling the main movements of the crane.
DC 24 V, two batteries in series.
6WG260, German ZF automatic transmission.
77.16USt hook block, 4 sheaves, single hook.
German KESSLER axles with great load bearing capacity. Both front and rear axles are drive axles for steering.
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.
Auxiliary which system
Driven by hydraulic motor, with built-in
planetary gear reducer, constant-closed brake and anti-coiling wire rope equipped.
4 tires, each axle is equipped with single tire, load bearing capacity is great.
Tire specifications: 33.25 R29.
2-section,lattice and box welding structure,
with three jib offset angles of 0° , 20° and 40° available.
Full hydraulic electro-proportional multimode steering: front axle independent steering mode, tight-turning radius mode, crab walk mode and rear axle independent steering mode.
Equipped in the cab, for improving comfortable performance.
Service brake: double-circuit full-hydraulic disc brake, acting on all wheels. Selfbraking 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.
120USt hook block, 8 sheaves, double hook. 27.56t hook block, 2 sheaves, single hook. 7.72USt hook block, single hook.
Main winch system
Driven by hydraulic motor, with built-in planetary gear reducer, constant-closed brake and anti-coiling wire rope equipped.
It has features of high speed with a light load and low speed with a heavy load.
An electric pump automatically delivers lubricant to pivots and so on, improving maintenance convenience and lubrication
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° .
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
