FRB804 Hydraulic Tensioner

The FRB804 features two pairs of independently controlled bull-wheels, offering 2 x 31,500 lbf (140 kN) or 1 x 63,000 lbf (280 kN) of tensioning capacity for stringing one or two bundled conductors. The bull-wheel grooves are made from high resistance interchangeable nylon sectors. The FRB804 is completely electronically controlled.
