The pipelayer is an important construction equipment in the
construction of oil and natural gas pipeline, which is mainly used
for distributing, matching and ditching operations of large
diameter pipe.
Major Component
A series of HGY pipe crane using Cummins engine and crawler
chassis, rigid structure, lengthening and widening crawler,
hydraulic mechanical transmission.
The working device adopts full hydraulic drive, which mainly
realizes 3 actions: lifting and landing of the hook; Swing of the
boom; Lifting and landing of counterweights.
Two separate hydraulic winches drive the boom and the hook. The
boom is made of low alloy high strength steel, solid box profile
welded structure. The crane is equipped with the intelligent
monitor of the crane, the automatic limit device of the hook and
the automatic limit device of the boom, which can monitor and
control the working condition of the crane in real time. The DGY
pipe crane has good micro performance and fast hook falling
function.

Product Advantages
1, Pipeline operation performance is strong
The plant is specially designed to handle the rigors of pipeline
operations
2, Strong ability to work on slope
Low center of gravity, excellent machine balance and differential
steering contribute to superior handling and uphill capability in
narrow operating areas.
3, Easy to operate
Equipped with labor-saving, ergonomic control device, one hand can
operate all the control devices and functions of the pipe crane.
The common cab function between different types of crane makes it
easier to use.
Product Features
A. Excellent performance
1, The integrated powertrain with differential steering and the
updated hydraulic system work in tandem to provide the power and
improved machine handling required for any crane application.
2, Electro-hydraulic devices increase machine productivity by
providing better response and precise control of variable speed
motors with heavily loaded winches.
3, Excellent counterweight shape improves lifting ability.
4, Differential steering maintains maximum power on both tracks,
enabling top-notch steering performance even when the boom is
loaded, while improving handling in narrow operating positions.
5, The improved center of gravity, the lengthened track support
wheel and the repositioned rear guide wheel give the track a larger
ground area, thus improving the machine's ability to work on hills.
B. Designed for operators
1, Equipped with machine control handle, one hand can operate all
the machine control devices and functions of the crane.
2, The control handle adopts ergonomic design, which saves effort
in operation and reasonable positioning. It can synchronously
position the sling, boom and retractable counterweight accurately.
3, The double brake pedal control device improves the steering and
steering performance of the machine.
4, The planetary gear differential steering system facilitates
superior handling in tight operating areas and enhances uphill
performance.
C. Built-in safety feature
1, Load torque indicator (LMI) is standard.
2, Convenient ladders, handlebars and guardrails facilitate safe
access to the cab.
3, A large roof window with a retractable sunshade, additional
mirrors and sloped doors help with better views of the ditch, boom
and cylinder block.
4, The standard operator position detection system allows the
machine to turn when the operator is not seated, but locks the
powertrain to avoid accidental movement.
5, The rear view camera is standard, and two additional cameras are
optional to further improve the view around the machine.
