● |
|
Jib |
One-section lattice structure. Three offset angles of 0°, 15° and 30° are available. It is stowed along the side of the boom. Jib length: 9.0 m. |
● |
|
Frame |
Made of high strength fine grained steel, welded torsion-resistant frame type construction with large cross-section, high load-bearing capacity. |
● |
|
Outrigger |
4 outriggers, H-shaped arrangement, which are controlled by electrical and hydraulic and located at both sides of chassis frame. |
● |
|
Engine |
QSB6.7-C220-30,with rated power of 164kW/2200r/ min, max. torque of 949N.m /1500/r/min, manufactured by DF Cummins, in line six-cylinder water- cooled compression ignition diesel engine, off-road EU Stage IIIA emission standard compliant Fuel tank capacity：Approx. 305 L. |
● |
|
Gearbox |
6WG210, automatic transmission from ZF Germany, with 6 forward and 3 reverse gears. |
● |
|
Axles |
Both front and rear axles are for driving and steering, and the axles have features of great load bearing capacity. |
● |
|
Suspension |
Front axle is rigidly connected with frame; rear axle is equipped with swing hydraulic suspensions, which have cushioning function 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, increasing operation stability. |
● |
|
Tires |

● |
|
Steering |
Front axle independent steering, tight turning radius steering, crab walk steering and rear axle independent steering modes are available. |
● |
|
Brakes |
Service brake: double-circuit hydraulic disc brake, acting on all wheels. Alarm are available when the pressure in braking systemis too low. Parking brake: spring-loaded brake, acting on front axles, hydraulic- released independent disc brake. |
● |
|
Hydraulic system |
A dual-variable displacement pump, used for hoisting, elevating and telescoping operations, and a gear pump, used for slewing, outrigger, steering and braking operations; a load sensitive proportional multi-way change valve is used as main valve; an independent hydraulic oil radiator. Tank capacity: approx. 942 L. |
● |
|
Operating mode |
Hydraulic controlled pilot operation systemis equipped with two levers controlling the main movements of the crane. |
● |
|
Electrical System |
24 V DC, two sets of 12 V battery in series. |
● |
|
Main and auxiliary winch system |
The systemis driven by a hydraulic motor through a planetary gear reducer, with a normally closed brake and a balance valve equipped. |
● |
|
Slewing system |
Single-row four-point ball contact slewing ring, driven by a hydraulic motor through planetary gear reducer, and with a normally closed brake fitted. |
● |
|
Operator's cab |
Tiltable cab, with sliding door and adjustable seat equipped. It is equipped with safe glass and roof protective grille. Sun shade is available for windshield and roof window. Heater and air conditioner, radio, 12 V and 24 V DC outlets are standard. |
● |
|
Safety devices |
