803591493 Length Sensor for XCMG XCA100 All Terrain Crane

Product Overview

The 803591493 length sensor (Model D8.4DJ.1500.M134.3612) is an essential electronic spare part exclusively designed for XCMG XCA100 100-ton all terrain crane. As a key component of the crane load moment limiter system, this boom length sensor is installed inside the six-section main boom of XCA100 crane, which has a maximum extension length of 60 meters. It collects real-time data of boom extension length and working angle, and transmits stable CAN bus signals to the crane main controller and cab display. This part effectively prevents overload and over-range operation, ensuring safe lifting in construction, mining and road engineering. All 803591493 sensors are fully tested for precision, signal stability and sealing before delivery. Toprunparts keeps abundant stock of XCMG crane electronic parts to serve global maintenance shops, leasing companies and engineering contractors.

Installation & Working Principle

This pull-wire type length sensor is fixed at the bottom of the crane main boom, and the built-in steel wire rope is connected to the top boom head. When the boom stretches or retracts, the mechanical displacement is converted into standard digital signals by internal precision components. The signals will be displayed on the cab instrument and linked to the load protection system to realize automatic alarm and safety interlock. During installation, please keep the steel wire rope straight to avoid extrusion and distortion, which can effectively extend the service life of the sensor.
