Transmission Line Stringing Equipment Hydraulic Cable Puller With
Electric Starting Engine
Hydraulic cable puller is one of the construction equipment for
erecting aerial High Voltage Transmission Line and laying
Underground Cable/OPGW/ADSS, which can be used to set up tower,
erect guide (ground) lines smoothly & conveniently, such as laying,
traction in various complex conditions .This machine is mainly
equipped with small tension machine, used in the laying of the
traction rope, but also in the case of the cable wire traction.

Safe operation rules
Only those who are familiar with safe operation rules and
maintenance requirements of the type puller and receive
professional training are allowed to operate the puller.
1. Both operators of tensioner and puller shall communicate each
other to avoid that puller begins to work under operating condition
of tensioner not tension laying and cause serious accident.
2. When puller works, it is prohibited that operators give up
operating or leave puller.
3. When operating puller, you shall control handle and adjust
pressure smoothly and steadily and avoid over-violent and quick
force and brutal operation.
4. Absolutely avoid using backing the machine to brake.
5. After starting puller, check the meter whether it operates
normally; stop to check if abnormal.
6. When the puller works, continuously observe each pointer; water
temperature of engine shall be not more than 95℃; Hydraulic oil
temperature shall be not more than 85℃; Tail bracket hoisting
pressure shall be not more than 14Mpa; Brake pressure shall be not
less than 2Mpa and not more than 4Mpa. Otherwise, the machine shall
be stopped immediately for check.
7. Pressure of each safety valve shall be preset, avoid random
adjustment by all means! If accidents, for example, puller fails to
work, are caused arising from adjusting valve without permission,
it will bring you much trouble and loss.
8. When puller operates, rotary speed of engine keeps above
2000r/min to maintain higher power and prevent overheating of
hydraulic oil.
9. Under operating condition of driving, to change driving
direction of puller shall be carried out after pulling wheels stop
completely.
10. When puller operates, prohibit filling oil and repairing; when
needing repairing, make engine flame out, in addition to reliable
brake.
