PRODUCT
DESCRIPTION
  • It is compatible with port-specific equipment such as container gantry cranes, quay cranes, stackers, reach stackers, and trailers. All specifications of bore diameter, rod diameter, and stroke can be customized. It has a strong rated pressure capacity and can withstand heavy loads, start-stop impacts, and continuous high-intensity operations for a long time.
  • The cylinder barrel is fabricated from premium 20# steel precision-honed seamless tubing, ensuring high inner wall smoothness and low friction loss. Combined with a fully automated robotic welding process, the overall structure is rigid, fatigue-resistant, and deformation-resistant. Under the high-load and continuous operation conditions of port environments, it can operate reliably and leak-free for a long time.
  • The piston rod is made of 45# steel base material and comes standard with hard chrome plating protection. It can also be equipped with high-end anti-corrosion and wear-resistant processes such as nickel-chromium electroplating, QPQ treatment, and laser cladding. It effectively resists sea wind salt spray, damp rain, and dust erosion, and features excellent resistance to wear and scratches, making it perfectly suited for the highly corrosive outdoor working environments of ports.
  • Explosion-proof valves, balance valves, hydraulic pipelines, and special installation connectors can be provided as needed. The normal operating temperature range is -25 °C to +110 °C, and it supports customization for special working conditions such as high/low temperatures and enhanced salt spray corrosion protection, meeting the all-weather, long-term stable operation needs of various ports around the world.
Cargo handling motion

Configure the Cylinder for Port Handling Duty

A port machinery hydraulic cylinder can power lifting, luffing, steering, stabilizing and attachment motion on cargo-handling equipment. The correct configuration depends on the load case, stroke, installed dimensions, mount geometry, hydraulic pressure and duty cycle. Salt-laden air, rain and washdown exposure should also be stated before seals and surface protection are selected.

Engineering review

Drawing and Environment Review

Send the assembly drawing, load case and hydraulic schematic. We review pin alignment, side-load risk, port access, hose movement and installation clearances together with the required corrosion protection. Replacement inquiries should also include the existing part number, measured interfaces and clear installed photographs.

Buyer questions

Port Machinery Cylinder FAQ

Which port machines can use these cylinders?

Applications can include container handlers, reach stackers, mobile harbour equipment, cranes, ship loaders and stabilizing systems.

How is corrosion protection selected?

State the salt, rain and washdown exposure, service interval and coating requirement. These conditions are reviewed with the rod surface and sealing system.

What dimensions are needed for a replacement?

Provide bore, rod diameter, stroke, closed and extended lengths, mount and pin dimensions, port details and the available installation envelope.

Can one cylinder specification cover different machines?

Only when the load case, geometry, pressure, mounts, ports and environment are confirmed equivalent. Machine model alone is not enough.
