Tension Stringing Equipment Maximum Intermittent Tension 130KN
Hydraulic Tensioner 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 can meet the tension of 220KV double-split
LGJ-630 and below conductors in mountainous and hilly terrain; the
tension of optical cables such as OPGW or AESS in various terrains;
the tension of 500KV traction rope under various terrains and the
reverse pulling. | Characteristics | - The TY1×120III tension machine adopts a single-axle trailer
structure with a beautiful appearance. The front end is equipped
with a reversible traction tractor, which is convenient for
hauling.
- The main components such as the engine, main hydraulic pump,
hydraulic motor, reducer, and main valve block are all imported
parts, and the system runs stably and reliably.
- Adopt German Rexroth planetary reducer and hydraulic motor, compact
structure, form an advanced closed loop hydraulic transmission
system, advanced technology, power saving, high transmission
efficiency and reliable quality.
- The laying tension is steplessly adjustable, the display is
intuitive, and it has a good pull back function.
- The friction plate wet brake is integrated in the planetary reducer
to avoid daily maintenance. Spring brake, hydraulic release, easy
operation, short response time, can achieve no gap braking, safe
and reliable, in the stopped state, it can prevent the line running
accident caused by the loosening of the tail line.

| Transmission System | With closed double-loop hydraulic transmission system and planet
decelerator, tension wheel is driven by primary gear. With
inversion, 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(Germany
