Reliable Manufacturing and Quality Control
ZHY Hydraulic provides hydraulic cylinder solutions for heavy-duty equipment, mobile machinery, industrial systems, and custom OEM applications. Our manufacturing process focuses on strength, sealing performance, machining accuracy, welding reliability, corrosion resistance, and maintenance-friendly design.
High-Strength Materials
Hydraulic cylinders can be manufactured with high-strength steel tubes and chrome-plated piston rods to improve wear resistance, load capacity, and service life in demanding working conditions.
Precision Machining
Controlled machining accuracy helps reduce internal friction, improve sealing contact, support smooth movement, and extend cylinder operating life.
Advanced Sealing Systems
Seal selection can be adjusted according to pressure, temperature, movement frequency, contamination risk, and working environment to reduce leakage and early seal failure.
100% Pressure Tested
Every cylinder undergoes rigorous hydraulic fluid power testing for proof pressure and internal/external leakage before leaving our manufacturing facility.
Heavy-Duty Welding
Strong welding quality is important for end caps, clevis mounts, trunnions, brackets, and other load-bearing structures, especially in construction, mining, lifting, and truck applications.
Custom Engineering
Bore size, stroke length, rod diameter, mounting type, port position, pressure rating, surface treatment, and cylinder structure can be customized according to drawings, samples, or working parameters.
Corrosion Resistance
Painting, plating, coating, and surface treatment options help protect hydraulic cylinders used in outdoor, marine, agricultural, and harsh industrial environments.
Maintenance-Friendly Design
Proper gland design, standardized wear parts, accessible seals, and clear technical confirmation can help reduce maintenance difficulty and equipment downtime.
Common Problems and ZHY Solutions
Many crane cylinder problems come from wrong sizing, poor sealing, insufficient pressure holding, rod surface damage, side load, or inaccurate installation dimensions. ZHY reviews application details before production to reduce these risks.
| Common Problem | Possible Consequence | ZHY Solution |
|---|---|---|
| Cylinder drift under load | Boom or outrigger position changes during operation | ZHY improves sealing design, piston fit, and pressure holding performance. |
| Oil leakage | Seal wear, rod damage, poor surface finish, or contamination | ZHY selects proper seals, controls rod surface quality, and checks leakage before shipment. |
| Slow or unstable boom movement | Wrong bore size, internal leakage, poor alignment, or hydraulic mismatch | ZHY confirms force, stroke, pressure, and installation dimensions before production. |
| Telescopic boom extension problem | Wrong stroke, poor machining, or excessive seal resistance | ZHY reviews open length, closed length, stroke, and boom structure. |
| Outrigger cylinder cannot hold load | Internal leakage, weak seal system, or insufficient pressure capacity | ZHY recommends suitable sealing and pressure-tested assembly. |
| Rod rust or scoring | Outdoor exposure, poor chrome plating, mud, rain, or marine environment | ZHY supports hard chrome rods, anti-corrosion treatment, and export packing. |
| Replacement cylinder cannot fit | Wrong pin size, mounting width, stroke, or oil port direction | ZHY checks drawings, photos, and key measurements before production. |
