description

This genuine swivel joint with wing plates is precision turned and lapped from high‑strength alloy steel. Integral locating wings with mounting holes lock the outer housing while the inner rotary core remains free to turn. Multi‑stage combined seals and wear‑resistant rotary pairs withstand repeated hydraulic surges for durable sealing. When the hopper lifts and feeding motors run, hydraulic lines swing continuously. The wing plate prevents the whole fitting from spinning with hoses and lowers the risk of loose threads and leakage. Leakage, stiff rotation, cracked wings or elongated mounting holes will reduce hydraulic pressure and weaken feeding power. Replace the complete assembly if seals degrade or running surfaces are scored during overhaul.

product parameters

- Part No.: 800302177
- Name: Hydraulic Swivel Joint with Wing Plate
- Applicable Model: XCMG RP705 medium crawler paver
- Material: Alloy structural steel
- Process: CNC turning, integral wing forming, heat treatment, precision lapping, seal assembly, high‑pressure testing
- Matching parts: High‑pressure hose, ferrule fittings, sealing rings, fixing bolts
- Function: Rotary hydraulic connection, anti‑rotation positioning by wing plate, vibration damping, torsion relief and oil circuit sealing

Applicable Scenarios

Hydraulic transition for paver hopper lift cylinders; oscillating oil lines for feeding drive motors; positions where swinging hoses tend to spin fittings; replacement for leaking, damaged or seized old swivels; overhaul and maintenance of feeding hydraulics; pre‑assembly and positioning for new hydraulic piping.

advantage

- Integral locating wing plate locks the housing against rotation and prevents thread loosening caused by spinning hoses
- Precision original machining with standard threads, sealing faces and wing holes for easy fitting
- Multi‑seal construction withstands high pressure and resists leakage under harsh site conditions
- Smooth rotary pair releases torsional stress and extends service life of high‑pressure hoses
- Modular assembly for quick full replacement and shorter downtime

FAQ

Q: Can only seals be replaced for leaking swivel joint with wing plate?
A: Seal replacement works only for aged seals with intact running surfaces. If the rotary surface is scored, leakage will recur quickly; full replacement is recommended.

Q: Must the wing plate be firmly fastened during installation?
A: The wing plate shall be secured to lock the outer housing. Without proper fixing, the anti‑rotation function fails and threads may loosen.

Q: Does stiff rotation mean the swivel is broken?
A: New swivels carry normal preload. Progressive stiffening together with leakage indicates internal wear and requires replacement.

Q: Can this wing‑style swivel replace ordinary swivels of the same part number?
A: Replacement is allowed if space permits. Secure the wing plate, check hose clearance and pressure test before operation.
