Cable Stringing Equipment Max Continuous Tension 2×65kN Hydraulic
Tensioner Performance Parameter | 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 | 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 | Engine | Model: Cummins 4BT3.9-C105 Nominal speed: 2800r/min Nominal power (1 hour): 77KW | Electrical System | System voltage: 24V Storage battery: 6-QA-110 Diesel engine starting: 24V electric starting | 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) Model: A2FM90 | Speed reducer | Type: planet Gear Decelerator Model: 307 L2 Reduction ratio: 17.4 Brake opening pressure: 2.5MPA |
Characteristics - TY2x70IV Hydraulic Tensioner 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.
- TY2x70IV Hydraulic Tensioner 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.
- TY2x70IV Hydraulic Tensioner 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.
