• Dual-pump combined technology, hydraulic flow expanding steering,
and single-handle guide control, flexible and convenient.
• The steering limit is dual limits of hydraulic control and
mechanical control. The hydraulic control limit is prior to the
mechanical limit, reducing the impact.
• Fully hydraulic wet brake, low pressure protection, combination
of emergy brake and parking brake, ensuring the safe traveling.
With the electromagnet positioning technology, the machine has the
automatical leveling function, decreasing the working labor of the
operator and improving the work efficiency.
• Intelligent and independent ventilation system could change the
fan speed according to the working condition, saving the energy and
improving the economics of the machine.
• Integrated lubricating system ensures the normal operation of
each friction part.
• Long wheelbase, centered distribution of the articulation
centers, good reliability of the machine.
(1) Experienced parts
• The imported Cummins QSM11 electrical injection, turbo-charing,
air-air inter-cooling engine, electric start and flameout. The
emission meets the requirement of TIRE-3 stage
• ZF electrical and hydraulic control transmission features
advanced performance, strong reliability, and smooth gear shift; KD
gear function reduces the gear shift frequency during the operation
and improves the working efficiency.
• ZF wet drive axle is equipped with slip-limited differential and
non-maintenance multi-disc wet brake block, prolonging the service
life of the axle.
• The main parts of the brake system, hydraulic system and
lubricating system adopt the international famous brands to improve
the reliability of the systems.
• The electrical system adopts the electronic monitor. The plug
connectors adopt full sealing type, and are installed to the
position where it is difficult to be rained and splashed.
(2) Comfortable operation environment
• New cab of large space features good sealing and wide visibility.
• The cab is equipped with air conditioning, radio, cup holder and
adjustable instrument panel, featuring comfortable and safe
• Electronic monitoring warning system monitors the running status
of the machine accurately.
• The single-handle guide hydraulic control provides easy operation
for the operator.
• The boom lifting limit function prevents the mechanical impact.
• The electrical control gearshift control handle features accurate
and easy controlling.
(3) Reliable structure strength
• Heavy load structure design, thick board, high strength.
• The key structural parts adopt finite-element analysis to ensure
the adaption to various kinds of dangerous conditions.
• The frame of single board structure features high structure
strength, and average stress distribution.
(4) Convenient maintenance
• With integrated oil filling, the service person could access to
the maintenance point from the ground, featuring higher efficiency.
• The side plates of the shield and rear shield are opened easily,
and it is convenient to check the engine and parts, and daily
(5) Thoughtful design
• The key articulated positions adopt two-stage dustproof,
preventing grease overflow and dust entry and reducing the abrasion
of the pin, prolonging the service life and decreasing the
operation and maintenance cost.
• The hydraulic pipeline adopts two-level sealing of 24° cone and O
ring, settling the common issue of leakage.
• Durable blade and bucket teeth feature longer service life.
• The easily worn pipeline is equipped with the protection bush,
prolonging the service life.
