Hoisting Weight Limiter QCX-BY-2/1-5T-14-P

Overview

QCX-BY series hoisting weight limiter safety protection device for single beam, double hoist and other crane equipments. The device is mainly composed of two parts: resistance strain sensor and electrical controller. It has the functions of sound and light alarm, cutting off the power supply of the crane hoisting circuit, and digital display of the weight. This series selects the side pressure tension sensor, and the control instrument selects the QCX-B/II single display instrument.
