Solenoid Coil Overview

This is the solenoid coil that operates the 4WE6D directional control valve on SANY telescopic cranes and truck cranes. Energised, it pulls the valve spool across so hydraulic oil is routed to the function you have selected — boom telescope, outrigger, winch or swing. The coil sits over the spool end at one side of the valve body and plugs into the machine wiring through a single connector; the winding is matte black and the body beneath it is satin metal.

A weakening coil rarely stops a crane outright. It takes out one function at a time, which is why coils are among the crane spare parts that repair shops and fleet workshops keep on the shelf instead of ordering one under pressure after a breakdown.

Coil Design & Connection

• Same connector, no rewiring — the plug-in coil connector matches the original wiring plug, so the coil goes on without cutting into the loom or changing the terminal layout.
• Wound for repeated switching — the winding is built around the constant energise-and-release cycles of crane control, which is where low-cost generic crane parts tend to fail early.
• Matched to the 4WE6D valve body — the coil is sized for the 4WE6D directional valve so the spool travels fully in both directions and the selected function responds normally.
• Function-checked before dispatch — every unit is tested, wrapped and shipped with its identification label legible, so it can be compared with the failed part on the bench.

Technical Specifications

Cross-Reference & Fitment

Numbers matter more than names here. Depending on the machine and its build date, the same coil is listed as 60275748, G2304130063241, 330672 or 60256011, and the valve it sits on may be marked 4WE6D-L6X, L6B or L68. They belong to one valve family, which is why an OEM replacement parts order should be placed against the number printed on the label rather than the machine model alone.

Two minutes with a phone camera prevents a wrong shipment. Photograph the label on the valve, the connector on the coil and the marking on the body, then send them with the machine model and year. If the label has worn away, the machine model plus the function that has failed is usually enough to identify the right coil.

Crane Applications

• Boom telescope control on the RT65 — this is the circuit the coil is ordered for most often; when it weakens, the boom telescopes slowly or stops while every other crane function still works.
• Outrigger and stabiliser circuits on SANY truck cranes — the same valve body sits on truck crane manifolds, where a failing coil shows up as an outrigger that will not extend, retract or hold.
• Winch and swing control — an intermittent coil drops a function in and out under load, the pattern that most often gets misdiagnosed as a pump or relief valve problem before the coil is tested.
• Crawler crane and drilling rig manifolds — the same valve family appears in the hydraulic systems of FUWA crawler cranes and SANY rotary drilling rigs, so the coil is ordered as part of wider construction machinery spare parts work as well.
• Workshop rebuilds and fleet stocking — repair shops and fleet teams keep a coil on the shelf beside other heavy equipment parts, because one failed coil can idle a machine for days while a replacement is sourced.

Technical Support & Model Matching

Not sure which part fits your machine? Send us the OEM part number, the machine model, and a photo or drawing, and we will help you match the correct item. We supply crane and construction machinery spares across Cummins, SANY, Caterpillar and FUWA applications, covering solenoid valves and coils, angle sensors, wiring harnesses, couplings and load moment indicators. We also assist with fitting questions, wiring checks and fault tracing, and can produce custom parts to your drawings when a standard item is not the right answer.
