handle the severe conditions with ease.

≥7,500kg lifting capacity and 170kN breakout force handle all

kinds of materials with ease.

Technologic position

Optimized version of ZL50G, the leadership model of China’s
3rd generation loaders.

Gathering of dozens of technologies.

Excellent quality power and drive systems

Strong power

China-II emission compliant special engine features
low speed and low fuel consumption.

With strong power and high torque reserve factor,
this engine meets the instant overload demand
during operations and sufficiently provides the
power required for heavy-load operations.

The three-stage desert filter element features simple
maintenances and low cost.

Optional Shangchai engine SC11CB220G2B1

XCMG’s patented technology
Heavy-duty energy-conservation transmission and
torque converter assembly

The special high capacity torque converter ensures
the maximum utilization of engine power.

The enhanced design and the application of
imported products for critical carrying parts effective­ly improve the overload capacity of transmission.

The drive shaft flanges are of DIN and SAE specifi­cations and the distribution diameter of the fastening
bolts is enlarged to realize super-strong torsion
resistance and adapt to high strength and
heavy-load continuous operations.

SPACIOUS CABIN

The design of cab and access passages is ergonomically opti­mized to create the best driving and riding experience for the oper­ator from the first touch of the machine.

All-new digitalized VDO combination instrument features beauty and elegance.

The steering wheel , seat and the pilot joystick are freely adjustable depending on the operator's habits.

The pilot control features accurate and handy operations, with the control box in follow-up motion with
the seat.

The easily and naturally observable instruments, the panoramic glasses, and the super-large spherical
rearview mirrors ensure a broad vision and easy and safe operations.

The integrally full-enclosed skeleton structure cab is slightly pressurized and is fitted with high-power air
conditioning system to realize noise reduction and heat insulation and build a comfortable, healthy, and
safe driving environment.

The full-coverage exquisite interior trim parts
and the damping and noise reduction
measures for the cab and engine hood
reduce the noise by more than 6dB.

The super-large spherical rearview mirrors
enlarge the visual field by 30%.

Human-oriented design

The complete accessories, including
cup holder and charging port, are
provided.

Guarantee safety and reduce fatigue

Convenient get-on/get-off and high operation safety: The arrangement of ladders and handrails conforms to EU
standard (CE standard) and the anti-skid perforation measure is taken for the operation platform.

Stable braking: The air-assisted hydraulic four-wheel caliper brakes
feature stable braking and high safety and reliability.

Double-limit: The double-limit (hydraulically flexible and mechanically
rigid modes) is applied for steering limit (primary flexible mode and
secondary rigid mode) to ensure impact-free and destruction-free and
high operation comfort.

Automatic high-position leveling: The bucket incorporates the
automatic high-position dumping and leveling function and the
transport position stop block function to improve the working efficien­cy and reduce the splashing of material during operations.

Flow amplifying steering: The full-hydraulic flow amplifying steering
system ensures handy and flexible steering.

Long-tested super-strong heavy-duty

All-new enhanced heavy-duty design further upgrades the reliability and

structural parts

Frame structure of super-strong carrying capacity

The heavy-duty design, and robot welding ensure secure welds, high torsion resistance efficiency, and
strong overload capacity.

The finite element analysis technology is adopted to reduce the stress concentration and eliminate the
partial weaknesses so that the frame is resistant against impact and overload and handles with ease all
kinds of overload conditions.

prolongs the average life by 20%.

Diversified bucket design

Standard bucket suitable for diversified working conditions.

Rock bucket: It’s dedicated for handing of hard materials (such as
rock), featuring good resistance against wear and impact.

Coal bucket: It’s dedicated for handling of bulk materials (such as
coal), featuring high bucket capacity and high efficiency.

High strength wear-resistant bucket design

Application of high strength wear-resistant material

The bucket is thoroughly made of high strength steel plates to
improve the wear resistance and impact resistance by more than
30% and prolong the service life.

Specially enhanced critical portions

The reinforcement ribbed plate structure design is applied for critical
load-carrying portions to prevent the distortion and deformation of
the bucket.

Secure and reliable frame hinge joints

The centering design of main hinge joints reduces the
turning radius and lowers the tire wear and energy
consumption.

The large spacing between upper and lower hinged
plates realizes high structural strength and sufficient
maintenance space.

The pioneering double-row tapered roller bearings are
adopted for the main hinge joints, featuring high
carrying capacity and long service life.

Optimized boom hinges

The dumping impact is reduced by 30% to remarkably improve the
reliability of bucket and boom.

International quality hydraulic and electric units

The first-class distributor valve and flow amplifying valve
(steering priority and double-pump confluence) guarantee low
pressure loss, less system heat, and high reliability of parts.

The international brand hydraulic pump supplies stronger
hydraulic power.

The international quality hydraulic hoses applied feature high
heat and pressure resistance and long life.

The hydraulic pipelines adopt double sealing means (DIN
standard 24º taper thread + O-ring) to achieve better sealing
performance and effectively solve the leakage problem.

07/08

The harnesses are made of imported quality material and the
process layout is optimized to ensure reliable electric circuit
system.
