Tlx55 torque limiter (hereinafter referred to as the force limiter) and control system for truck cranes. TLX55 type force limiter provides the crane operator with abundant and effective working information, which makes the crane be used effectively in the range of its design parameters. With many kinds of signal sensors and instruments, force limiter can provide real-time information of arm length, angle, working range, rated lifting weight and actual lifting weight to the operator. When the crane operation beyond the allowable safe range, the force limiter will send an alarm to remind the operator to stop the illegal operation, and send an automatic lock to the dangerous direction movement control signal. The system consists of display host, length sensor, Angle sensor, hydraulic sensor, height limit switch, etc. .

Main function display-visually display the actual lifting weight, rated lifting weight, arm length, angle, working conditions, magnification and other crane operation parameters, pre-alarm when the crane occurs any of the following situations, tlx55 torque system alarm sound. - crane torque overloading-crane hoist overrun-force limiter system failure control with the crane electrical system, when the system alarm, any of the following dangerous direction operations are prohibited:-boom down luffing-boom out-hoist lifting at this time, the system only allows safe direction operation, namely:-jib up luffing-jib retraction-jib down

Features and performance set host and display in one, compact structure, small size, easy to install, easy to understand interface, with data recording function (Black Box) , optional USB download interface, it can cycle and record the overload data of the crane, and can completely reproduce the relevant data when the crane is overloaded, real-time display of Crane rated load, actual load, amplitude variation, arm length, angle, magnification, time, sound and light alarm and automatic control with graphics and Chinese characters on the display screen; Direct input of lifting rope multiple, hook weight and working mode keys, full key operation, make installation and debugging method simpler and data more accurate; Sensor Zero Drift, temperature drift, automatic tracking compensation, can ensure long-term weighing error in the range of national standards;
