Frame

Torsion-resistant box girder frame fabricated from

high strength fine grain structural steel.

Electrical system 24V system voltage, CAN bus.

Outrigger Four fully hydraulic H-type outriggers. The span is 7.2m

when outrigger fully extended, 5m when half extended

and 3.1m when fully retracted.

SuspensionAutomatic full hydraulic oscillation lockouts on rear axle

permits oscillation only with boom centered over the front.

Wheel and tire4 wheels, 29.5× 25, 28 PR（optional 29.5R25）

SteeringFull hydraulic power steering system allows four steering

modes: front wheel, rear wheel, four-wheel coordinated

or four-wheel crab steer.

Transmission system Power-shift transmission with divided torque converter

provides 6 speeds forward and 6 speeds reverse. Four

wheel drives engages automatically with low range and

two wheel drive with high range.

AxleFront:driving/steering with differential and planetary

reduction hubs, rigid-mounted to frame. Rear: driving/

steering with differential and planetary reduction hubs

pilot-mounted to frame with hydraulic lockout cylinders.

BrakeFull hydraulic split circuit operating on all wheels.

01

EngineWater-cooled 6 cylinder Cummins diesel engine

（ Cummins QSB6.7）, displacement:6.7L. rated

186kw (250 horsepower)at 2500rpm, torque 987Nm at

1500rpm,fuel tank capacity: 305L.

SPECIFICATIONS/CHASSIS

02

CabFramed steel construction, sliding door, inserted safety

glass throughout, huge inner space and optimum

visibility, adjustable steering wheel. The deluxe

adjustable seat includes head and arm rests. Front and

upper window with windscreen wiper. Air-conditioner.

Boom elevationBoom luffing, double action hydraulic cylinder, boom

angle -2°- +78°.

Hydraulic systemSystem consists of two gear type off the transmission.

Combined system capability is 443 lpm. Load

feedback, constant power control. Standard full flow

oil filtration system and hydraulic oil cooler. Hydraulic

tank capacity is 620L, with external sight level gauge.

Main boom11.25-34.5m (37-113 ft.) four sections boom, formed

in a hexagonal cross section. Maximum lifting height:

35.8m (117ft).

HoistHydraulic winch with bent axis piston provides

2-speed operation with equal speeds for power

up and down. Winch is equipped with an integral

automatic brake, grooved drum, tapered flanges,

standard cable roller on drum, and an electronic drum

rotation indicator. Rope diameter 19mm.

Slew unitHydraulic motor drives a double planetary reduction

gear. Heavy duty multiple disc swing brake is

mechanically actuated from operator’s cab by foot

pedal.

Safety devicesEquipped with telescopic boom balanced valve,

lifting and luffing balanced valve, vertical cylinder with

dual-direction Hydraulic lock. Swing cushion valve

and turntable lock, lifting height limiter and 3-ring

protector. The self-designed moment limiter includes

large display screen, visual and audible warning

system and automatic function disconnect. The crane

operation displays boom radius, boom angle, boom

length, allowable load, actual load and percentage of

actual to allowable using a bar graph. Anti-two block

system includes audible & visual warnings and

automatic function disconnects.
