Product details

1. Product Definition & Core Functions

Definition:

AKawasaki (Kawasaki Heavy Industries) Original Equipment Manufacturer (OEM) joystick control assemblydesigned specifically for Sumitomo Heavy Industries' 80-ton construction machinery (e.g., excavators, cranes). It integrates hydraulic control, electronic signal transmission, and human-machine interaction.

Core Functions:

• Multi-Axis Proportional Control: Supports dual-axis (X/Y) or triple-axis (X/Y/Z) precision operation for combined boom, arm, and bucket movements.

• Force Feedback System: Real-time hydraulic pressure feedback via sensors enhances operational safety.

• IP67 Protection: Dustproof and waterproof design for harsh environments (e.g., mud, rain).

• CAN Bus Communication: Seamless integration with the equipment’s ECU (Electronic Control Unit) for fault diagnostics and parameter calibration.

6. Common Failures & Maintenance

【表格】

Symptom Potential Cause Solution

Unresponsive Joystick Sensor disconnection, wiring fault Check DT connector pins, replace harness

Sluggish Operation Stuck valve spool, contaminated oil Clean valve block, replace hydraulic fluid

Signal Drift Hall sensor zero-point offset Recalibrate sensor via diagnostic tool

Water Damage Short Aged seals, cracked housing Replace O-rings, repair housing

Maintenance Schedule:

• Every 500 hours: Inspect handle bolts, clean cooling slots

• Every 2,000 hours: Replace hydraulic filter, test sensor output

7. Procurement Considerations

1. Part Number Verification:

• Kawasaki OEM Part No.:KAWASAKI P/N: KJCA-80S-1234

• Sumitomo Matching Part No.:SUMITOMO PART: SH80-JCA-001

2. Anti-Counterfeiting:

• Authentic Kawasaki labels include laser holograms (verify via official website).

• Avoid "salvaged" or "refurbished" parts (no warranty).

3. Alternative Options:

• If OEM parts are unavailable, considerRexrothorParkercompatible units (confirm protocol compatibility).
