The 60047424 outrigger pressure transducer is part of the machine stability monitoring system found on SANY mobile cranes and similar lifting equipment.

1. Product Design
The transducer is a sealed sensor with a threaded hydraulic port and an electrical connector. It has a steel body rated for the working pressures found in typical crane hydraulic systems. The internal element is a piezoresistive or strain gauge type sensor that responds to pressure changes in the outrigger circuit.

2. Core Function
The transducer measures hydraulic pressure in the outrigger cylinder circuit. As the outrigger cylinder extends or retracts against the load, fluid pressure changes. The sensor reads these changes and outputs a corresponding analog voltage or current signal. This signal goes to the crane control unit, which calculates ground pressure and monitors machine stability. The system uses this input to prevent overload conditions and warn the operator when stability limits are being reached.

3. Physical Installation
The transducer is installed at the hydraulic manifold block or directly on the outrigger cylinder port. Access requires opening the outrigger compartment. The sensor is threaded into a standard hydraulic port with a sealing washer or O-ring. Electrical connection is made through a mating connector that matches the machine harness.

4. Maintenance and Replacement
Routine inspection includes checking for leaks around the thread connection and verifying that the electrical plug is secure. Pressure readings can be compared against a test gauge port for system checks. Replacement involves disconnecting the electrical plug, unscrewing the old sensor, and installing the new one with the correct torque and fresh sealant. The hydraulic circuit should be depressurized before service.

This transducer is used on various SANY truck crane models
