LW322 Length and Angle Sensor for XCMG Large Cranes
The LW322 combines boom-length and angle measurement for compatible XCMG crane LMI systems. Cable-reel mechanics, angle reference, electrical signals and system calibration must all match.
Identification and Matching
LW322 label and revision
Crane boom configuration
LMI display/controller model
Reel cable length and connector
Mounting and angle reference
Application and Service Scenarios
Investigate when length or angle data is missing, jumps, sticks or disagrees with physical boom position. Reel spring, measuring cable, gearing, wiring and calibration can cause similar faults.
Inspection and Installation
Secure the boom, control reel spring tension and install in the original orientation. Set cable routing and reference points, then calibrate length and angle across the approved range.
Frequently Asked Questions
Can LW322 be used on any large crane?
No. Measuring range and LMI configuration must match.
Why does length jump?
Check cable, reel gearing, connector and signal before replacing.
Must both channels be calibrated?
Follow the system procedure for length and angle verification.
Export Packing
The reel is immobilized, cable and connector are protected, and the assembly is cushioned in a rigid crate.
