Product Advantages
Super Strong Lifting Performance
Adopted 5-section U-shaped main boom with strong lifting performance, making the product outshine products of its tonnage in the
industry.
Equipped with four-axle dedicated automobile chassis and 9-speed gearbox, therefore the product has excellent driving
performance and strong trafficability and maneuverability.
High-efficiency Dual-pump Confluence Technology
Adopted an all-new hydraulic system design, which can realize the manual switch between telescopic & luffing dual-pump and
single pump. In the event of confluence, telescopic & luffing operation speed is increased by up to 50%. When the telescopic &
luffing operation switches to single-pump operation, the calorific value of the hoist will be decrease by 50%.
Excellent Driving Performance
The newly-developed engine in-cylinder brake
and exhaust brake combination makes the
vehicle’s retarder brake capability increased by
three folds. When driving downhill along a long
slope, the vehicle speed is more stable. Retarder
brake and brake linkage make the brake
distance decreased by 10%.
Safe and Reliable Telescopic System
The boom telescopic control technology with
national patent makes the lifting boom extend
and retract according to the specified sequence,
as a way to avoid the cylinder bending and boom
braking resulting from incorrect operation, which
helps improve operation safety. Dedicated
balance valve plug is adopted to prevent the
balance valve from suffering oil leakage and
avoid the cylinder’s retraction.
In case of mis-operation, special valve core is
used to prevent the core tube from bending.
Normal operation order:
For stretch, second section
first extends, followed by
third, forth, and fifth sections.
For retraction, third, forth,
and fifth sections first retract,
and then third section.
Core tube
Steady Operating System
The hoisting mechanism is integrated with the load sensing filter technology,
making the system free from influence by the changing of load pressure and
oil pump flow rate. Thus, the hoisting speed can be adjusted more precisely.
Also, the hydraulic system’s energy consumption and calorific value can be
reduced, and its service life will be prolonged in return.
Application of the slewing buffering technology with unique structure makes
the slewing system operate steadily and without jittering. Luffing system is of
high efficiency and energy conservation, and drops steadily.

All-new Human-centric Design
Additionally equipped with hoist monitoring mirror to reinforce the safety in application.
Adopted single H-shaped gearshift model and new-type operation flexible shaft mechanism to make the operation convenient
and comfortable, which fully exemplifies the human-centric design philosophy.
