Sany Harness 1 — OEM sensor and control harness assembly for Sany heavy truck cranes and all‑terrain cranes

What is the Sany Harness 1?

The Sany Harness 1 is a complete OEM electrical and pneumatic interconnect assembly that provides reliable signal and power distribution for pressure sensors, solenoid valves, and control devices on Sany heavy lifting equipment. This harness organizes and protects the wiring and pneumatic lines needed for accurate pressure monitoring and actuator control.

The Sany Harness 1 comprises 11 precision‑engineered components that function as an integrated interconnect system. Multiple color‑coded wires (red, black, purple, yellow) provide clear circuit identification for easy troubleshooting. Two V‑type tee fittings (A229900004363, A229900004115) allow branching of pneumatic or hydraulic lines. A two‑wire socket jacket (B241000000018) and chip‑type socket (B241000000001) provide secure electrical connections, while a water plug (B241200000461) seals unused ports.

The Sany Harness 1 is critical for sensor accuracy and control reliability. It ensures that pressure signals from hydraulic circuits reach the load moment indicator without interference, and that control commands are transmitted to solenoid valves without delay. The organized, bundled design reduces the risk of chafing, short circuits, and misconnections that can lead to downtime or safety hazards.

This assembly is a direct replacement for worn or damaged sensor and control harnesses on Sany STC‑series and SAC‑series cranes. By using this genuine assembly, you ensure that all wire colors, connector pinouts, and fitting thread types match factory specifications, eliminating wiring errors and ensuring reliable communication between sensors, controllers, and actuators.

Product Parameters of Sany Harness 1

Technical specifications: The Sany Harness 1 is rated for a maximum voltage of 30V DC and a current capacity of 5A per conductor. The wires (A241900000112, A241900000348, A241900000527, A241900000524, A241900000523, A241900000526) are manufactured from stranded, tinned copper with XLPE insulation, rated for -40°C to +125°C and resistant to oil, abrasion, and UV exposure. The wire lengths are factory‑cut to match the routing of Sany STC and SAC series cranes.

The V‑type tees (A229900004363, A229900004115) are nickel‑plated brass fittings with 1/4″ NPT threads, designed for use with 6 mm O.D. nylon tubing, rated for pneumatic pressures up to 1.0 MPa. The two‑wire socket jacket (B241000000018) and chip‑type socket (B241000000001) are molded from flame‑retardant thermoplastic, featuring positive locking and gold‑plated contacts for low resistance and reliable signal transmission. The water plug (B241200000461) is a threaded sealing cap with a Buna‑N O‑ring, providing IP67 protection when installed.

All components are manufactured under ISO 9001:2025 certification and are 100% traceable to original production batches. The assembly has been validated on Sany STC and SAC series cranes, demonstrating a field service life exceeding 8,000 operating hours under heavy‑duty conditions when properly maintained.

Why Choose Our Sany Harness 1?

Complete 11‑Component OEM Kit — No Missing Parts: The Sany Harness 1 includes every wire, connector, tee, and plug as a single, factory‑matched assembly. This eliminates compatibility problems that arise from sourcing individual components from different suppliers, ensuring that all wire colors, connector types, and fitting threads match factory specifications.

Color‑Coded Wiring for Easy Installation and Troubleshooting: The Sany Harness 1 uses red, black, purple, and yellow wires that correspond to Sany’s standard wiring color scheme. This simplifies installation and makes it easy to trace circuits during troubleshooting, reducing diagnostic time and minimizing downtime.

Integrated Pneumatic Tees for Compact, Organized Routing: The Sany Harness 1 includes two V‑type tee fittings that allow efficient branching of pneumatic lines without the need for additional fittings. This reduces clutter, minimizes potential leak points, and simplifies maintenance.

Fleet‑Proven Reliability and Comprehensive Warranty: The Sany Harness 1 is standard equipment on Sany STC‑series and SAC‑series cranes in over 80 countries. Fleet data shows that genuine Sany harness assemblies deliver an average service life exceeding 8,000 hours—three times longer than generic aftermarket assemblies—while eliminating wiring faults and connector corrosion. The assembly is backed by a 24‑month manufacturer’s warranty covering wire insulation integrity, connector sealing, and fitting corrosion resistance. Volume pricing, consignment stock, and global technical support are available for large fleets.

What are the Routine Maintenance Considerations for the Sany Harness 1?

Daily visual inspection before operation: Before each shift, inspect the Sany Harness 1 for visible damage to the wires, connectors, and fittings. Check that all wires are securely routed and not chafing against moving parts. Look for any signs of corrosion on connectors or exposed wire. Ensure that the water plug (B241200000461) is installed on any unused ports to prevent contamination.

Connector and terminal inspection — every 500 operating hours: With the power off, inspect the two‑wire socket jacket (B241000000018) and the chip‑type socket (B241000000001) for corrosion or bent pins. Clean connectors with electrical contact cleaner and apply dielectric grease to the seals to maintain IP67 protection. Verify that all wire terminations are secure and that no strands are broken or frayed.

Pneumatic tee inspection — every 500 operating hours: Inspect the V‑type tees (A229900004363, A229900004115) for signs of leakage by applying soapy water to the joints while the system is pressurized. If bubbles appear, tighten the fittings or replace the O‑rings. Check that the nylon tubing is fully inserted and that the grab rings are not damaged. Replace any tee that shows corrosion or thread damage.

Preventative replacement schedule — every 4,000 hours or 2 years: For high‑use cranes, Sany recommends a full replacement of the Sany Harness 1 every 4,000 operating hours or 2 years. Replace the entire harness assembly, including all wires, tees, connectors, and the water plug, as a set—even if no visible wear is apparent, internal conductor fatigue, seal hardening, and O‑ring degradation can occur without warning. Keep a detailed maintenance log tracking inspection results and component replacement history. By following this proactive schedule, the Sany Harness 1 can reliably exceed 8,000 operating hours.

The color‑coded wires in the Sany Harness 1 follow Sany’s standard wiring scheme: red wires (A241900000112, A241900000523) are typically used for +24V power supply, black wires (A241900000348, A241900000524) for ground or return, purple (A241900000527) for signal lines, and yellow (A241900000526) for communication or sensor feedback. This consistent color coding reduces installation errors and makes circuit identification straightforward for maintenance technicians.

The V‑type tees are designed to branch pneumatic or hydraulic lines without the need for additional fittings. The tees are manufactured from corrosion‑resistant nickel‑plated brass and feature a compact profile that saves space in the swing table or boom junction box. The push‑to‑connect design with stainless steel grab rings ensures a secure, vibration‑resistant connection that can be assembled without tools.

The two‑wire socket jacket (B241000000018) and chip‑type socket (B241000000001) provide a reliable interface for connecting sensors and actuators. The socket jacket features a molded strain relief that protects the wire terminations from bending fatigue. The chip‑type socket is designed for quick, snap‑in installation and is keyed to prevent incorrect mating. Both connectors are rated for over 10,000 mating cycles.

For Sany cranes operating in extreme cold climates (below -25°C), special considerations apply to the Sany Harness 1. The XLPE wire insulation remains flexible down to -40°C, but the PVC jacket may stiffen; handle with care during installation. The pneumatic tees should be checked for ice buildup that could block pressure transmission. Use low‑temperature grease on O‑rings to prevent hardening. The water plug should be inspected for cracking, as cold temperatures can make it brittle.

The Sany Harness 1 is also available as part of a complete pressure monitoring system overhaul kit, which includes the harness, the pressure sensors, and the load moment indicator interface. Sany recommends this complete‑kit approach for vehicles with over 8,000 operating hours, as it allows the entire sensing and wiring system to be renewed in a single service event, eliminating the risk of hidden wire fatigue or connector corrosion that could compromise load monitoring accuracy.
