Engineering & Construction Hydraulic Cylinders — TBM, Excavator, Pile Driver OEM

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

Engineering & Construction Cylinder Applications

Tunnel boring machine (TBM) thrust cylinders

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 and shield cylinders

TBM gripper cylinders clamp the tunnel wall to provide thrust reaction; shield cylinders steer and articulate the TBM body. Critical precision and reliability requirements.

Pipe jacking and micro-tunnelling

Long-stroke jacking cylinders for pipe jacking stations; compact cylinders for micro-TBM cutter head drives and steering. Bore Ø80–Ø300 mm.

Excavator bucket, arm, and boom cylinders

High-cycle, high-contamination cylinders for hydraulic excavator digging circuits. Heavy-duty wiper seals and robust rod coatings for longevity.

Road roller and motor grader cylinders

Cylinders for drum vibration locking, cab levelling, blade lift, blade side shift, and wheel lean on road construction machinery.

Hydraulic piling rig and rotary drill

High-force cylinders for crowd (mast feed), Kelly bar drive, and casing oscillator actuation on piling and rotary drilling rigs.

Bridge launching beam and prestress jacks

Synchronised cylinder sets for incremental bridge launching; high-force flat jacks and strand jacks for structural prestressing operations.
