Puller-tensioners

Hydraulic Puller-Tensioner AFS507
  • The machine is suitable to string one or two ropes or bundled conductors.
    The bull-wheel grooves are made up of high resistance interchangeable nylon sectors.
    The machine is completely electronically controlled.
    Note: The machine is also available with bull-wheel grooves made of wearproof heat and chemically treated steel (AFS517).

  • ENGINE

    DIESEL

    104 kW (140 hp)

    COOLING SYSTEM

    water

    ELECTRICAL SYSTEM

    12 V

    HYDRAULIC TRANSMISSION

    Closed hydraulic circuit that allows stepless speed variation in both rotating directions.
    This machine is provided with a pull presetting system that maintains 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 occur.
