Displacement Sensor 60279855 – SANY Truck Crane Parts

The SANY Displacement Sensor 60279855 is an electrical component used in the boom control system of SANY truck cranes. It functions as a length/angle sensor that monitors boom extension and position, providing real-time feedback to the crane’s control system for safe load moment limiting and boom geometry calculations.

Technical Specifications

Function & Operating Principle

The displacement sensor operates within the crane’s boom electrical system, detecting the linear displacement and angular position of the telescopic boom sections. This data feeds directly into the Load Moment Indicator (LMI) system, which calculates safe working loads based on boom geometry . When the sensor signal is compromised, the crane’s computer display may show incorrect load readings or fail to calibrate properly during no-load setup .

Compatibility & Fitment

This sensor is designed for SANY truck crane models equipped with the 60279855 sensor part number. SANY truck crane series commonly requiring displacement sensors include:

• STC Series: STC75, STC200, STC250, STC500, STC1000, STC1300

• QY Series: QY25C, QY100, QY130

Important Verification Note: SANY uses multiple sensor part numbers across different production batches and crane configurations. Part numbers in similar ranges (such as 60027398 for L-15000-24-C2 linear displacement sensors) may appear visually similar but have different specifications. Always verify compatibility against your machine’s Parts Book or provide the crane serial number when ordering .

Why Verify Before Ordering

SANY crane electrical systems integrate multiple sensors into a single control network. The boom electrical system alone includes proximity switches, angle/length sensors, and overwind detectors that must communicate correctly with the main controller . Installing an incompatible sensor can trigger diagnostic faults, prevent proper LMI calibration, or cause incorrect load readings—a critical safety concern for lifting operations.
