Tension Stringing Equipment Hydraulic Tensioner 1500mm Bull-wheel
Diameter Purposes and Characteristics - TY2x70IV hydraulic tensioner is a kind of large and high efficiency
power construction machinery.
- It’s mainly used for delivery of all kinds of wire, optical cable
and traction rope.
- It has high allocation of overall performance, ample power reserve,
high delivery speed and wide use.
- It could meet tension delivery of wires like double Spacer LGJ-630
or below in mountain or upland, optical cables like OPGW or AESS in
all kinds of terrain as well as tension delivery and
counter-stretching of wires like 500 KV traction rope in all kinds
of terrain.
- Two machines could meet tension delivery of wires like Four Spacer
LGJ-720 or below in plain.
Characteristics - It could deliver or counter-stretch two wires at the same time,
tension and traction of every wire could be adjusted separately and
seen from manometer directly. Otherwise, one wire could stop or
deliver under tension while another wire is counter-stretching and
collecting.
- It adopts hydraulic motor from Germany Rexroth and compose
double-circuit hydraulic transmission system. It has advanced
technology, high transmission efficiency and credible quality and
could save power.
- It adopts planetary reducer from Germany Rexroth, has compact
configuration and credible quality.
- Friction plate type wet brake is adopted and integrated in
planetary reducer, it Can be free from routine maintenance. With
spring brake, hydraulic release, simple operation, short reaction
time, it can realize gapless braking, it’s safe and reliable. In
shutdown mode, all kinds of hydraulic filters have bypass valves to
protect the system from damage.

| 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)
