product parameters

- Part Name: Rear Crossbeam
- Part No.: 200635814
- Compatible Model: XCMG RP705 medium crawler paver
- Material: High‑strength rectangular steel tube and structural steel plate
- Process: Cutting, assembly welding, stress relief, machining of datum holes, sandblasting, painting
- Built‑in Structure: Main beam, reinforcing diaphragms, mounting supports, locating flanges, lifting points
- Function: Support rear assemblies, set screed reference, carry auger units and transfer loads

Applicable Scenarios

Suitable for overhaul and refurbishment of XCMG RP705 crawler paver; full replacement when the original rear crossbeam is twisted, weld‑cracked, support‑torn or heavily corroded; spare part for highway and municipal asphalt paving projects; core load‑bearing structural stock for construction parts suppliers.

- OEM datum dimension: All locating holes and mating surfaces fit the machine without extensive alignment work and preserve screed reference.
- Robust welded construction: Internal reinforcing diaphragms deliver strong bending and torsion resistance against sagging under load.
- Post‑weld stress relief: Reduces residual stress and lowers the risk of fatigue cracking under sustained vibration.
- Durable anti‑corrosion coating: Sandblast primer plus topcoat slows rust penetration on site.
- Integrated multi‑point supports: Pre‑fabricated mounting points for direct fitting of screed, augers and guards.
- Stable paving accuracy: Rigid reference minimizes thickness variation and improves finished pavement quality.

FAQ 

Q: Can rear crossbeam 200635814 fit other paver models?
A: This crossbeam is designed exclusively for XCMG RP705. Rear mounting span, screed connection layout and datum height are customised. Cross‑model swap is not recommended without full dimensional verification.

Q: Can small cracks be repaired by welding instead of full replacement?
A: Minor cracks on secondary welds may be repaired after professional inspection. If the main beam weld cracks, the beam twists or support roots tear, full replacement is recommended to avoid catastrophic failure.

Q: What are the key points during installation?
A: Lift and align carefully to match datum holes, tighten bolts diagonally in stages, and check screed level after installation to calibrate paving reference.

Q: What visible paving problems are caused by deformed rear crossbeam?
A: Typical symptoms include uneven left‑right paving thickness, wavy pavement, uneven screed wear, persistent auger noise and aggravated material segregation.

Q: How to maintain the rear crossbeam?
A: Remove hot asphalt residue after work; inspect main welds and support roots regularly; avoid heavy impact or dragging; touch up damaged paint promptly.
