Technical specifications

Structural members

Turntable and frame are made of fine grainec high strength steel, with anti-torsion large cross-section frame structure, have heavy load-bearing capacity.

Boom

I basic boom and 3-telescoping sections, quadrilateral cross section welding structure. Single-cylinder plus ropes telescoping mechanism is for synchronous telescoping.

6 pulleys on boom head are standard. Boom length: 10.9m ~ 34.5m.

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 equipped with all-weather and large arc glass, which has a wide vision, as well as spacious and comfortable due to ergonomic inner design.

Equipped with air conditioner.

Engine

QSB6.7-C 190-30, in line six-cylinder water- cooled compression ignition diesel engine, manufactured by DCEC, rated power 142kW/ 2200rpm, max. torque 931Nm / 1400rpm, offroad U.S. EPA Tier 3/EU Stage IIIA emission standards.

Fuel tank capacity : Approx. 300L

Safety devices

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 fixed displacement pump driven by

 engine is used for controlling the movements of crane.

Oil tank capacity: Approx. 700L.

Counter weight

Total weight is 5t, fixed counterweight,

Operating mode

Hydraulic controlled pilot operation system is

equipped with two levers controlling the main movements of the crane.

Electrical system

DC 24 V, two batteries in series.

Gearbox

6WG160, automatic transmission imported

from ZF Germany, with 6 forward and 3 reverse gears available.

Hook

501 hook block, 25t hook block,41 hook block are standard.

Axles

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

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.

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.

Jib

2-section,lattice and box welding structure, with0° , 15° and 30° jib offset angles available.

Jib length:9.5m ~ 16m.

Tires

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

Tire specifications :23.5 R 25.

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.

Steering

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

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

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 axle, hydraulic-released independent disc brake.
