Transmission System With closed double-loop hydraulic transmission system and planet
decelerator, tension wheel is driven by primary gear. hen inverted,
the magnitude of reverse traction force is led by exit pressure of
pump. In tension condition, hydraulic motor rotation is driven by
the tension wheel; the magnitude of tension is controlled by
regulating the motor exit pressure. Main pump: - Type: Hydraulic control bidirectional variable plunger pump( German
Rexroth)
- Model: A4VG90HD3
Hydraulic motor: - Type: Two-way Quantitative Plunger Piston Motor( German Rexroth)

Safe Operation Rules | Only the workers who are familiar with safe operation rules and
maintain demand of this tension machine and are professionally
trained could be allowed to operate. |
| - When operating tensioner, you shall control handle and adjust
pressure steadily and avoid over-violent and quick force and brutal
operation. When tension laying , special attention shall be paid to
prevent reducing or increasing tension to a large extent to result
in conductor fluctuating greatly and damaging span frame and other
buildings.
|
| - Both operators of tensioner and puller shall communicate each other
to avoid that puller begins to work under operating condition of
tensioner not tension laying and cause serious accident.
|
| - Absolutely prohibit using reverse pulling function to brake.
|
| - Regularly check the fixed bolt of the nylon sector, prevent loose
bolt to damage the wires and cause unnecessary losses.
|
| - When tensioner works, it is prohibited that operators give up
operating or leave puller.
|
| - When tension stringing, the pull handle should be middle position.
It is forbidden to throw the handle to prevent to cause serious
accident as running line.
|
| - In the process of tension laying , continuously observe each
pointer; water temperature of engine shall be not more than 95℃;
hydraulic oil temperature shall be not more than 85℃; Oil-filling
pressure shall be not less than 1Mpa and not more than 1.8Mpa;
brake oil pressure shall be not less than 1.8Mpa and not more than
4Mpa. Otherwise, the machine shall be stopped immediately for
check.
|
| - When tensioner operates, rotary speed of engine keeps around
1200r/min to maintain higher power and prevent overheating of
hydraulic oil.
|
| - In the process of tension laying, it is strictly prohibited that
brake handle is put in brake position; otherwise, serious accident
will be caused.
|
| - Under operating condition of driving, to change driving direction
of tensioner shall be carried out after tension pulleys stop
completely.
|
| - Pressure of each safety valve shall be preset, avoid random
adjustment! If accidents, for example, tensioner fails to work, are
caused from adjusting valve without permission, it will bring you
much trouble and loss.
