RT55U 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.
0-426.6 ft/min, no load, 4th layer,
0-426.6 ft/min, no load, 4th layer
Approx. 70s for boom elevation from -1.5° to 80°
Approx. 140s for boom extension from 10.3m to 38.2m
Turntable and frame are made of fine grained high strength steel, with anti-torsion large cross-section frame structure, has heavy loadbearing capacity.
Ibasic boom and 4-telescoping sections, quadrilateral cross section welding structure. Double-cylinder plus ropes telescoping mechanism is for synchronous plus sequential telescoping. 6 pulleys on boom head are standard. Boom length:33.8ft ~ 1253ft.
4 outriggers, H-shaped arrangement, which are controlled by electrical and hydraulic and located at both sides of chassis frame. Front and rear towing brackets are available.
Integrated design, appearance is simple and artistic, equipped with all-weather and large arc glass, which has a wide vision, as well as spacious and comfortable due to ergonomic inner design.
QSB6.7, in line six-cylinder water-cooled compression ignition diesel engine, manufactured by Cummins, US, offload U.S. EPA Tier 3/EU Stage IIIA emission standards,rated power 200bhp/21 OOrpm, max. torque 5461b.ft / 1500rpm, or off-road U.S. EPA Tier 4rEU Stage IV emission standards,rated power 200bhp/2200rpm, max. torque 6861b.ft / 1500rpm.
Fuel tank capacity : Approx. 79.2gal
Hydraulic balance valve, Hydraulic relief valve, Hydraulic double-way valve, LMI., Lowering limiter avoids wire rope overreleasing. Anti-two block at boom head avoids wire rope over-winding.
The constant variable displacement pump is connected to the transmission through PTO fbr controlling the movements of crane. Oil tank capacity: Approx.190gal.
Total weight is 13227.6b, fixed counterweight
Electric proportional controlled operation system is equipped with two electric proportional control the main movements of crane.
DC 24 volts is in series with two 12-voltbattery packs.
6WG260, automatic transmission imported from ZF Germany, with 6 forward and 3 reverse gears available.
90t hook block, seven sheaves, double hook.
Exclusive axles imported from KESSLER Germany, with both front axle and rear axle for driving and steering.
Front axle is connected with frame rigidly, swing rigidly lockable hydraulic suspension is used for rear axle. Road shock is buffered and travel smoothness is improved when driving on roads, the rear suspension cylinder may be locked to rigid state so as to meet the requirement fbr travel with a load suspended.
Auxiliary which system
Driven by hydraulic motor through planetary gear reducer and with built-in constant closed brake, equipped with anti-winding wire rope.
4 tires, each axle is equipped with single tire, large bearing capacity. Tire specifications:23.5 R 25.
2-section,lattice and box welding structure, with 0° , 20° and 40° jib offset angles avai- lable.Jib length:29.5fr ~ 55.8ft.
Electro-proportional hydraulic multi-mode steering: front axle independent steering, small turning radius steering, crab walk steering and rear axle independent steering are available.
Equipped in the cab, for improving comfortable performance.
Service brake: double-circuit hydraulic disc brake, acting on all wheels. Automatically braking function works when the pressure in braking system is too low.
Parking brake: spring-loaded brake, acting on front axles, hydraulic-released independent disc brake.
28USt hook block, three sheaves, single hook. 4.4USt hook block, the max. parts of line are 1, single hook.
Main winch system
Driven by hydraulic motor through planetarygear reducer and with built-in constant closed brake, equipped with anti-winding wire rope, having features of high speed with light load and low speed with heavy load.
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.
Single-row four-point ball contact slewing ring, driven by hydraulic motor through planetary gear reducer and with built-in constant closed brake, for 360 ° continuous rotation.
