Hengshui Machinery manufactures hydraulic cylinders for civil engineering, infrastructure, and construction machinery: tunnel boring machines (TBM), micro-tunnelling machines, pipe jacking systems, excavators, road rollers, piling rigs, motor graders, and bridge construction equipment. Engineering and construction cylinders typically operate in harsh outdoor environments with high levels of contamination, shock loading, and wide temperature cycles.
Our engineering cylinders are built for long service life in difficult conditions. We select heavy-duty wiper seals, stainless steel or chrome-plated rods, robust end caps with external protective coatings, and specify bore tubes of appropriate wall thickness for the buckling loads common in long-stroke excavator or piling applications. OEM manufacturing from machine builder drawings is our primary mode — we hold NDA agreements with multiple major OEM customers globally.
| Parameter | Specification |
|---|---|
| Bore range | Ø40 mm – Ø500 mm |
| Stroke range | 200 mm – 8,000 mm |
| Working pressure | 210 – 350 bar |
| Wiper seals | Heavy-duty polyurethane multi-lip — excludes mud, debris, water |
| Rod coating | Hard chrome 25–50 µm; optional ceramic chrome for extreme abrasion |
| Mounting | Pin eye, clevis, trunnion, flange — all orientations |
| Paint system | Zinc-rich primer + epoxy topcoat + polyurethane finish; custom colour match |
| Test | Pressure tested 1.5× working pressure; stroke cycle tested before despatch |
The largest engineering cylinder application: TBM thrust cylinders push the cutter head through soil or rock. Bore Ø200–Ø500 mm, stroke 1,000–2,000 mm, 350 bar. High-precision, synchronised sets.
TBM gripper cylinders clamp the tunnel wall to provide thrust reaction; shield cylinders steer and articulate the TBM body. Critical precision and reliability requirements.
Long-stroke jacking cylinders for pipe jacking stations; compact cylinders for micro-TBM cutter head drives and steering. Bore Ø80–Ø300 mm.
High-cycle, high-contamination cylinders for hydraulic excavator digging circuits. Heavy-duty wiper seals and robust rod coatings for longevity.
Cylinders for drum vibration locking, cab levelling, blade lift, blade side shift, and wheel lean on road construction machinery.
High-force cylinders for crowd (mast feed), Kelly bar drive, and casing oscillator actuation on piling and rotary drilling rigs.
Synchronised cylinder sets for incremental bridge launching; high-force flat jacks and strand jacks for structural prestressing operations.
All products available with custom bore, stroke, seals, and surface treatment. OEM/ODM manufacturing from drawings or samples.
