TY180 Hydraulic Puller For Power Line Construction Engine Rated
Power 239kw
Features:
1. The hydraulic cable puller consists of generator, closed
hydraulic system, reducer transmission system, traction wheel,
traction rope winding mechanism, operating system and mainframe.
The main tractor and the traction rope winding mechanism form an
integral whole. The whole machine layout is compact, the space
position is reasonable, the operation is comfortable.
2, the towing machine adopts two-wheel single-axle trailer
installation mode, convenient for field transportation. Traction
wheel, engine, hydraulic tank, operating disc are all reasonably
arranged on both sides of the beam. The strength safety factor of
anchoring point design is high, and it is safe and reliable.
3. Tractive force is treated by special technology to resist wear.
4. Traction can be turned positively and inversely, and the
traction force can be preset and displayed directly from the
pressure gauge.
5. The hydraulic cable puller is a hydraulic transmission type
tractor, which adopts German Rexroth hydraulic controlled oblique
disc variable pump and German Rexroth inclined shaft hydraulic
motor to form a closed circuit hydraulic transmission system.
Advanced technology, power saving, high transmission efficiency,
reliable quality, and self-overload protection function, to prevent
hydraulic impact damage and oil temperature rise speed up.
6. With the German Rexroth planetary reducer, compact structure,
reliable quality.
7. With the advanced hydraulic servo control or reversing in the
world, the traction speed can be adjusted smoothly and infinitely,
and the operation is light, flexible and reliable.
8. With friction plate wet brake, integrated in the planetary
reducer from daily maintenance. Spring brake, hydraulic release,
easy operation, fast reaction speed, can achieve gap-free braking,
safe and reliable. The line running accident caused by the
loosening of the tail rope can be prevented under the condition of
downtime. In case of sudden flameout or accident, the engine has
the function of self-braking protection.
9. The handle adopts positioning design, which is convenient and
timely. Accurate adjustment and control, easy to operate, reduce
the fatigue strength of the operator.
10. Using aluminum alloy plate fin radiator, driven by hydraulic
motor fan cooling, good cooling effect, stable working time. And
according to the specific environment and working temperature,
timely and convenient to adjust the size of fan air volume.
Hydraulic filters are equipped with bypass valves to protect the
system from damage.
