Design and Control on Automobile Crane Torque Limiter

Abstract

AMLU torque limiter is an automobile crane moment limiter. The torque limiter is detection vehicle crane lifting weight. Moment limiter can detect and display the gravity and torque dynamic change value. Vehicle mounted crane in the course of their work to detect arm angle and length, amplitude of cylinder pressure and other parameters. Vehicle mounted crane arm angle and length can be changed. Arm length detection is accomplished by length conversion mechanism. The same arm work angle detection need angle conversion mechanism. Arm length variation measurement using a retractable cable. Retractable cable tension is detected by the arm length of variable key content. Disc springs were used on the telescopic pull wheel force. Detection angle variation value using the weight arm angle converting mechanism. The angle conversion mechanism inside the box body of the injection of silicone oil can increase the oscillating damper. Reduce the detection angle fluctuation. Detection of signal processing and computer hardware design were also introduced.
