Technical specifications

Frame

Turntable and frame are made of fine grainec high strength steel, with anti-torsion large cross-section frame structure, has heavy loadbearing 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.

7 pulleys on boom head are standard.

Boom length:37.1ft ~ 141.7ft.

Outriggers

4 outriggers, H-shaped arrangement, which are controlled by electrical and hydraulic and located at both sides of chassis frame.

Operator's cab

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.

Engine

QSL, in line six-cylinder water-cooled compression ignition diesel engine, manufactured by Cummins, US, rated power 260bhp/21 00rpm, max. torque 7281b.ft/ 1500rpm, off-road U.S. EPA Tier 3/EU Stage IIIA emission standards,or off-road U.S. EPA Tier 4f7EU Stage IV emission standards.

Fuel tank capacity : Approx. 79.2gaL

Safetydevices

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 overwinding.

Hydraulic system

The constant variable displacement pump is connected to the transmission through PTO for controlling the movements of crane.

Oil tank capacity: Approx. 239.6gal.

Counterweight

Total weight is 19841.41b.3 counterweight combinations of 01b, 12125.3 lb and 19841.41b are available.

Operating mode

Electric proportional controlled operation system is equipped with two electric proportional control the main movements of crane.

Electrical system

DC 24 volts is in series with two 12-volt battery packs.

Gearbox

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

Additional equipment

Axles

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

Auxiliary which system

Driven by hydraulic motor through planetary gear reducer and with built-in constant closed brake, equipped with anti-winding wire rope.

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 for travel with a load suspended.

Jib

2-section,lattice and box welding structure, with 0° , 20° and 40° jib offset angles avai- lable.Jib length:31.2ft ~ 57.4ft.

Tires

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

Tirespecifications:29.5R29.

Air conditioner

Equipped in the cab, for improving comfortable performance.

Steering

Electro-proportional hydraulic multi-mode steering: front axle independent steering, small turning radius steering, crab walk steering and rear axle independent steering are available.

Hook

77USt hook block.

5.5USt hook block.

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 front axles, hydraulic-released independent disc brake.

Differential locks of front and rear axles

With these differential locks fitted, pass ability may be improved in case of slippingwhen 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-inplanetary 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.

Product parts list is as mentioned above, please refer to the product quotation for specific parts.

Slewing system

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.
