Cable Stringing Equipment TY2x70IV 2x70kN 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. | | Transmission System | 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 |
The Emplacement of Tension Machine - Haul puller into selected field to put; make incoming line groove
of pulling wheel aim to rod tower center as much as possible; the
deviation range is ±15°to reduce horizontal load.
- Anchoring puller. Center stressing direction of anchor bed shall
align with stretch direction of anchor in order to make anchor bear
pulling force and not bear lateral force. When anchoring, anchor
block, steel wire rope loop, shackle, lifting hoist or double hook
with above 5-ton stress shall be used; directly pre-tension the
anchor after jointing. Pull out the bolt of end leg and adjust the
leg to right position.
- The drum elevator is behind of tensioner into a fan-shaped, 10
meters off the tension machine, one side with brake disc should be
putted slower slightly. Anchor the drum elevators.
- Connect oil inlet pipe and return pipe of tail quick coupling to
the hydraulic tail vehicle. Attention that clean the dust and other
sundry in the connector to prevent them into hydraulic system.
Special Attention: - The force of the tension machine may be large, so it has
particularly high request for ground anchor to ensure the
reliability of the ground anchor.
- In mountains and hilly areas, due to the space limitations, the
tension machine can’t be in place at the center of the line, it has
to be pushed to the right place by manpower. During this process,
the potential energy of the machine should be paid particular
attention to.
