Technical specifications

Chassis

Superstructure

Frame

Designed and manufactured by XCMG,with all covered walking surface, anti-torsion box structure and optimal load-bearing structure design, made of imported high strength steel.

Frame

Designed and manufactured by XCMG; Full-covered walking platform, made of high-strength steel.            

Outrigger

4 outriggers, K-shaped arrangement, lateral and vertical outrigger controlled by the hydraulic control. Both sides of the chassis equipped with electronic control console,the console installed with luminous level,lighting and speed buttons; outrigger cylinders equipped with one-way valve, and the vertical outrigger has two-way hydraulic lock.

Hydraulic system

Variable pump driven by chassis engine, used for hoisting, elevating, telescoping and slewing operation. Imported electro-hydraulic direction valve, matching perfectly stably.Air-cooled hydraulic oil cooler, which may effectively reduce the temperature of oil in the system, suction filter and return filter.

Engine

MC13.48-50,in-line six-cylinder water-cooled EFI diesel engine, manufactured by SINOTRUK.rated power 356kW/1900rpm.max. torque 2300Nm / 1400rpm,.the national V emission standards.Fuel tank capacity : 380L.

Operating mode

The electric-proportional pilot control and PLC integrated intelligent control technology are adopted in the system. A control network between superstructure and carrier are formed through electric brush, Main movements of the crane may be realized smoothly and flexibly after combined with normal electric system.

Hydraulic system

The pump group is connected to the PTO hole of the engine fbr controlling the movements of outriggers.

Main winch system

Hydraulic controlled speed regulation, with groove drum equipped, driven by hydraulic variable motor through planetary gear reducer,and with built-in constant closed brake and balance valve fitted. Imported wire rope and pouch socket makes reeving easy and fast. It has features of high speed with light load and low speed with heavy load.

Gearbox

Electric controlled transmission imported from ZF Germany, with automatic AT control, with 12 forward gears and 2 reverse gears available.

Transfercase

Mechanical transfer box is originally imported from KESSLER Germany, equipped with an emergency steering oil pump and PTO which can transfer power to superstructure.

Alxes

High strength axle with reliable performance, manufactured by Xuzhou Meritor Axle, equipped with pneumatically controlled drum brake.

Suspension

Leaf spring is adopted for all axles, providing good shock absorbing effect.

Tires   

14 tires tire, 1、 2、 5 axles are equipped with single tire ,3、4 axles are equipped with double tire, manufactured by Double coin, large bearing capacity.Tire specifications: 12.00R24-20PR.

Brakes

Service brake: double-circuit air pressure brake, acting on all wheels.Parking brake: spring energy brake, acting on wheels of 2-5 axles.Auxiliary brake: engine exhaust brake,engine brake in cylinder.
