Auxiliary oilway hydraulic system
Open type constant displacement throttle speed governing hydraulic
system is supplied oil by gear pump and controls oil liquor’s
cooling and hoisting tail bracket’s lifting of the whole hydraulic
system through hand operated direction valve and ball valve.
- System working pressure: 12Mpa

Characteristics | - The puller is comprised of engine, closed-type hydraulic system,
speed reducer drive system, pulling wheel, coiling mechanism of
pulling rope, operation system and mainframe. The main puller and
coiling mechanism of pulling ropes make up a whole. There is
hydraulic lifting stabilizer in the forepart of frame, double
stabilizer in the rear part, when working, you can adjust them to
working location. The whole machine has compact layout, reasonable
space position and operation convenience.
- The puller adopts installation mode of two-wheel single spindle
trailer to be convenient for trans-field transportation. Pulling
wheel, engine, hydraulic oil tank and operation board are
reasonably arranged on both sides of main girder to make complete
machine realize single-point hoisting and convenient hoisting
transportation and reduce length of complete machine. The strength
safety coefficient of anchor point is big, safe and reliable.
- The pulling wheel is treated by special technology, which is
wear-resistant.
- The pulling wheel can rotate in positive and negative directions,
pull pulling rope and deliver pulling rope, and the pulling force
can be preset and displayed visually from pressure gauge.
- The puller is hydraulic drive type, adopts German Rexroth hydraulic
control sloping cam plate variable displacement pump, inclined-axis
hydraulic motor to form closed type circuit hydraulic drive system.
It has advanced technique, power saving, high drive efficiency,
reliable quality and self overload protection function to avoid
damage of hydrodynamic shock and acceleration of oil temperature
rise.
- Adopt German Rexroth planetary speed reducer with compact structure
and reliable quality.
- Adopt international advanced hydraulic servo control for pulling or
backing the machine at present and realize smooth regulation and
operation convenience, flexibility and reliability of pulling
speed.
- Adopt friction plate type wet brake; integrated in planetary speed
reducer; being free of routine maintenance, with spring brake,
hydraulic pressure release, easy operation and rapid reaction
speed; zero clearance brake can be realized, safe and reliable. In
stopped state, conductor-sliding off accident arising from release
of tail rope can be avoided. When the engine flames out suddenly or
fails, the brake owns automatic brake protection function.
- The control handle adopts locating design to be convenient for
timely and accurate regulation and control, easy operation and
reducing fatigue strength of operator. The operation board can be
opened directly from the front to be convenient for inspection and
maintenance.
- Adopt aluminum alloy plate fin radiator. The radiator is carried
out forced cooling through hydraulic motor drive fan, with good
heat radiation effect and long steady operation time, and can
conveniently and in time regulate air output of fan according to
practical environment and working temperature.
- All kinds of hydraulic filters have by-pass value to protect the
system free from damage.
