Swing drive
Hydraulic swing motor drives the swing supporting of inner joggle through a planetary reducer.
The normally engaged brake in drive system can ensure the safety of the machine.
Boom swing
The design of ultra-large angle boom swing mechanism makes the machine be applied at side
ditch, side channel, foot of wall and cliff. It better meets the current demand of both home and
foreign markets and broadens the use range of machine.
Chassis
The excavator chassis is a high tortuosity rigid steel structure part.
The large dimension pilot wheel and drive wheel provide best travel ability on severe road
condition and self-clean ability.
Undercarriage with the function of left and right track frame flexing has greatly improved the
stability of machine in operation.
The wheels and track are Shan Tui products with high stability and quality. The single element
of track device, such as oriented wheel, carrier roller, track wheel, have a long lubricant cycle
and don’t need to be maintained frequently.
Hydraulic track tension device can conveniently tension and loosen track.
The helix spring provides huge tension power for oriented wheel and ensures the track
orientation, avoid track digression.
High alloy steel track has good adhesion, stability and long service life.
Travel drive
Travel drive adopts axial piston double speed oil motor for power supply, providing high travel
speed and more traction.
Novel travel mechanism is a build-in structure with compact structure and high universality.
The variable system make the travel speed change from 0~2km/h to 0~3.5km/h.
Travel brake
Italian COMER piston motor and well-assorted brake drive adopt hydraulic brake “+” multiple
spring pressure brake (normally closed) to provide stable brake ability while working, especially
when working on the slope.
Compensation valve connected with travel motor can avoid overdrive when machine traveling
on slope.
Cab
The cab has two types, the common one & the brief one.
The common cab and flexibly installed cab tally with international standard on width, height and
structure.Wide front door can extend to the front and ensure convenient passage.
Glass around the cab and turnover front window provides best view for operator.
Cab seat is designed according to the ergonomics and can provide more comfort. The surface,
