Technical specifications

Structural members

Turntable and

frame are made of fine grained

high strength steel, with anti-torsion large cross-section frame structure, have heavy load-bearing capacity.

Boom

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.

Outriggers

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.

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.

Engine

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

Safetydevices

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.

Hydraulic system

The constant power variable displacement

pump is used fbr controlling the movements of crane.

Oil tank capacity: Approx. 720L.

Counterweight

Total weight is 6t, fixed counterweight,

Operating mode

Electric controlled pilot operation system is

equipped with two electric proportional

control levers controlling the main movements of the crane.

Electrical system

DC 24 V, two batteries in series.

Gearbox

6WG260, automatic transmission imported from ZF Germany, with 6 forward and 3 reverse gears available.

Hook

551 hook blockare standard.

Axles

Exclusive axles imported from KESSLER Germany, with both front axle and rear axle for driving and steering.

Additional equipment

Suspensions

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.

Tires

4 tires, each axle is equipped with single tire, large bearing capacity.

Tire specifications :23.5 R 25.

Jib

2-section,lattice and box welding structure,

with 0° , 20° and 40° jib offset angles available. Jib length: 9m 〜17m.

Steering

Full hydraulic multi-mode steering: front axle independent steering, tight turning radius steering, crab walk steering and rear axle independent steering are available.

Air conditioner

Equipped in the cab, forimprovingcomfortable performance.

Brakes

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.

Hook

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

drive wheels.

Slewing system

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.
