Puller-tensioners

Hydraulic Puller-Tensioner AFB707
  • The machine is suitable to string one, two, three or four ropes or bundled conductors with two pairs of bull-wheels with completely independent controls.
    The bull-wheel grooves are made of wearproof interchangeable nylon sectors.
    The machine is completely electronically controlled.

    *machine in configuration for 4 conductors; for 2 conductors see ALL080

    ENGINE

    DIESEL

    209 kW (280 hp)

    COOLING SYSTEM

    water

    ELECTRICAL SYSTEM

    24 V

    HYDRAULIC TRANSMISSION

    2 closed hydraulic circuits for stepless speed variation in both rotating directions.
    This machine is provided with 2 pull presetting systems that maintain the pre-set pulling value (also when the speed is reduced to “0”) by automatically adjusting the operation speed according to the friction and unexpected loads which may develop along the line.
