Cable Stringing Equipment Hydraulic Tensioner Max Intermittent
Tension 2×70kN Characteristics | - 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.
| - 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.
| - It adopts planetary reducer from Germany Rexroth, has compact
configuration and credible quality.
| - 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.

| Structure Parameters | Bull-wheel diameter: 1500mm | | Groove numbers: 2×8 | | Max conductor diameter: 40mm | | Weight of the whole machine: 10500kg | | Overall dimension (length, width, height): 5300X2300X2600 |
| Main technical performance | Tension condition | Max intermittent tension: 2×70kN | | Max continuous tension: 2×65kN | | Speed at max tension: 2.5km/h | | Max speed: 5km/h | | Tension at max speed: 2X35kN | | Traction condition | Max reverse pulling force: 2×60kN | | Speed at max pulling force: 2.5km/h | | Max reverse pulling speed: 5km/h | | Pulling at max speed: 2×30kN |
| 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

Purposes and Characteristics | - This tension machine is a kind of large and high efficiency power
construction machinery;
| - it has high allocation of overall performance, ample power reserve,
high delivery speed and wide use.
| - It’s mainly used for delivery of all kinds of wire, optical cable
and traction rope.
| - 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.
