RT55E 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.
0-130 ft/min, no load, 4th layer,
0-130 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
frame are made of fine grained
high strength steel, with anti-torsion large cross-section frame structure, have heavy load-bearing 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: 10.3m ~ 38.2m.
4 outriggers, H-shaped arrangement, which are controlled by hydraulic valves and cylinders that are controlled by electric signals and located at both sides of chassis frame. 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.
QSB6.7, in line six-cylinder water-cooled compression ignition diesel engine, manufactured by Cummins, US, rated power 149kW/2100rpm, max. torque 740Nm / 1500rpm, off-road U.S. EPATier 3/EU Stage IIIA emission standards.
Fuel tank capacity : Approx. 300L
Hydraulic balance valve, hydraulic relief
valve, hydraulic double-way valve and LMI.
Lowering limiter is equipped in winch to prevent rope over-releasing. Anti-two block is fitted on the boom head to prevent rope overwinding.
The constant power variable displacement
pump is used fbr controlling the movements of crane.
Oil tank capacity: Approx. 720L.
Total weight is 6t, fixed counterweight,
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, automatic transmission imported from ZF Germany, with 6 forward and 3 reverse gears available.
551 hook blockare standard.
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 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.
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 available. Jib length: 9m 〜17m.
Full hydraulic multi-mode steering: front axle independent steering, tight turning radius steering, crab walk steering and rear axle independent steering are available.
Equipped in the cab, forimprovingcomfortable 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 the front axles, hydraulic-released independent disc brake.
25t hook block,4t hook block.
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.
Differential locks of front and rear axles
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
Single-row four-point ball contact slewing
ring, driven by a hydraulic motor, with built- in planetary gear reducer and constant closed brake equipped. 360° continuous rotation is available.
