Each tong torque system consists of a tension load cell that converts line pull intoa hydraulic pressure signal, which it sends to a pressure-sensing gauge throughan interconnecting Hydraulic Hose. Each system also includes mounting hardware.Features:1) Systems designed and build for the rugged requirements of the oil filled2) Load Cell's are designed to ensure a long service life with minimum maintenance3) 6"Fluid filled gauge has years of proven reliability and ease of maintenance4) Target pointer on gauge helps operator maintain accurate torque
