Equator™ Rope Tensioning System

Unequal tension creates vibration and rope slip, leading to premature and excessive wear of ropes and sheave grooves. The Equator Rope Tensioning System helps prevent these unsafe conditions on all hoist ropes, supporting the elevator car and counterweight. Two identical injection-molded gauges compare and ensure the tension in traction lift hoist ropes can be equalized.

The Equator is fast to implement and rope tension measurements are accurate because the gauges are initially calibrated on the same rope. The lightweight gauges are supplied in a briefcase, complete with springs, hook bolts, adjusting spanner and rope locators. No power or data cables are required for operation. The system is designed for use on a range of lift ropes from ¼ inch to ¾ inch.
