Tensioners

Hydraulic Tensioner FRB804
  • The machine is suitable to string from one to six 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.
    Available with bull-wheels diameter 1900 mm (FRB806).
