Tension Stringing Equipment Hydraulic Tensioner Max Intermittent
Tension 2×70kN
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.

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. |
