Construction Hydraulic Cylinders
ZHY Hydraulic manufactures high-performance hydraulic cylinders for construction equipment, delivering reliable OEM manufacturer and custom aftermarket hydraulic cylinder solutions for excavators, loaders, bulldozers, cranes, dump trucks, and other heavy-duty machinery. Designed for high pressure, heavy loads, and demanding job sites, our cylinders provide exceptional durability, precision, and long service life.
Custom Construction Hydraulic Cylinders for Heavy Equipment
Construction hydraulic cylinders work in harsher conditions than many general industrial cylinders. Your equipment may face impact load, side load, dust, mud, rock contact, vibration, uneven ground, repeated cycles, and outdoor storage. A reliable cylinder should match the machine system, jobsite load, mounting structure, stroke requirement, and sealing environment.
ZHY manufactures custom construction hydraulic cylinders for boom, arm, bucket, blade, lift, tilt, steering, outrigger, stabilizer, and replacement functions. Your cylinder can be produced by drawing, old sample, equipment brand and model, or key dimensions.
If you are sourcing from a China construction hydraulic cylinder manufacturer and supplier, ZHY can support equipment builders, construction machinery repair companies, parts distributors, rental fleets, and hydraulic cylinder wholesalers with factory-direct custom production.

Replacement Construction Hydraulic Cylinder Support
When original construction machinery cylinders are expensive, delayed, damaged, or discontinued, ZHY can manufacture replacement construction hydraulic cylinders from drawings, photos, samples, and key measurements.
What to Send for Replacement Production
- Full cylinder photos: show the complete cylinder, rod end, base end, mounting ears, ports, and nameplate if available.
- Closed and open length: measure pin-to-pin length when fully retracted and fully extended.
- Bore and rod diameter: confirm the main force and strength dimensions as accurately as possible.
- Mounting dimensions: confirm pin diameter, mounting width, clevis gap, lug width, trunnion size, or flange layout.
- Port direction and thread: check oil port thread, position, hose clearance, and installation angle.
- Machine information: provide equipment model, cylinder function, working pressure, and photos of the installation area.
How to Choose Construction Hydraulic Cylinders
The right construction hydraulic cylinder depends on equipment type, cylinder function, jobsite load, pressure rating, stroke range, mounting size, and purchasing purpose.
Excavator, Loader and Bulldozer Cylinders
If your cylinder works in digging, loading, pushing, or blade movement, focus on impact load, rod strength, seal protection, side-load resistance, and replacement fitment.
Crane, Outrigger and Stabilizer Cylinders
If your cylinder supports lifting or stabilizing, focus on pressure holding, leakage control, long stroke stability, mounting safety, and smooth movement.
Replacement and Wholesale Cylinders
You can just send machine model,photos, drawings, or pin-to-pin length, bore, rod, stroke, port size, mounting width for review.
