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.
