Pull-Brake, Reversible Winches

Tension-Brake, Reversible Winches for FOCL-FOC-OPL. This section presents reversible pull-brake machines, winches for 35-110-220-330 kV overhead lines. Machines for installing conductors «under tension» with split phases and optical ground wire (OPGW) under tension on 330 kV overhead lines.
Reversible tensioning machines (hydraulic winches) with a double-drum capstan and interchangeable take-up drums with automatic leader rope winders, with a pulling force of 15-30-45-100 kN.
Reversible (tension-brake) machines differ from brake machines in that they can operate both as a tensioning machine and as a brake machine. This section presents the full range of reversible machines capable of performing tensioning or braking of one to four conductors/wires simultaneously.
Pulling equipment with the same maximum force can have different power ratings. Equipment productivity (pulling speed) is characterized by its power (50 kW is twice that of 25 kW equipment). Line pulling devices. Machines for pulling one or several (two, three, four split or two-by-two conductors) joint or independent wires. Twin and four-drum (quattro) winches.
