Product Specifications

Technical details and manufacturing context for Hydraulic Climbing Cylinders

Definition

Hydraulic climbing cylinders are precision-engineered hydraulic actuators that provide controlled, smooth vertical motion for climbing frame structures. As part of the climbing frame system, these cylinders enable adjustable height positioning through hydraulic pressure, allowing for safe and reliable elevation changes in industrial or recreational climbing equipment. The cylinders are designed to operate within a bore diameter range of 50–200 mm and a stroke length of 500–3000 mm, with an operating pressure of 16–25 MPa. Lifting capacity per cylinder ranges from 100 to 500 kN, depending on bore and pressure. Rod diameters vary from 28 to 100 mm, affecting buckling strength and retraction force. Operating temperature is specified as -20 to 80°C, beyond which seals may degrade or become brittle. The sealing system typically includes a U-cup and wiper, conforming to ISO 5597. Cylinder tube material is high-strength steel 27SiMn per GB/T 17396, while piston rods are made of 45# steel with hard chrome plating (20–50 μm) per GB/T 699. Surface treatment options are listed as zinc plating or painting for corrosion protection and require model-specific confirmation. ISO 9227 describes salt-spray test procedures; it does not select a surface treatment or establish product-specific corrosion performance without a separate product specification. Mounting types include flange, clevis, or trunnion, per ISO 6020-2. Weight ranges from 50 to 500 kg, affecting handling and structural load. These cylinders are components intended for integration into climbing frame systems; they are not standalone products. The working principle involves pressurizing hydraulic fluid to extend the piston rod and lift the frame, with controlled release for lowering. Selection requires verification of bore, stroke, pressure, and mounting interface against the specific climbing frame design. Always confirm model-specific values and standards with the legal manufacturer or supplier before procurement.

Working Principle

Hydraulic fluid is pressurized by a pump and directed into the cylinder chamber, forcing the piston rod to extend and lift the climbing frame. Controlled release of pressure through valves allows for precise lowering. The system typically includes hydraulic lines, control valves, and a power unit. The cylinder's bore diameter and operating pressure determine the force output, while the stroke length defines the climbing step height. Rod diameter influences buckling strength and retraction force. Seals prevent leakage and contamination, and the operating temperature range must be respected to avoid seal failure. Proper mounting and alignment are critical to prevent side loads that could damage the cylinder.

Frequently Asked Questions

What is the typical bore diameter range for hydraulic climbing cylinders?

The bore diameter typically ranges from 50 to 200 mm, per ISO 6020-2. The specific value determines the force output; larger bores provide higher capacity. Confirm the exact bore required for your application with the manufacturer.

What operating pressure is recommended for these cylinders?

The operating pressure is typically 16 to 25 MPa, per ISO 6020-2. Higher pressure increases force but requires thicker cylinder walls. Always verify the pressure rating of the specific model with the supplier.

What materials are used for the cylinder tube and piston rod?

The cylinder tube is made of high-strength steel 27SiMn per GB/T 17396, and the piston rod is 45# steel with hard chrome plating (20–50 μm) per GB/T 699. These materials provide pressure resistance and wear resistance.

What is the operating temperature range for these cylinders?

The operating temperature range is -20 to 80°C. Seals degrade above 80°C and become brittle below -20°C. Ensure the application environment stays within this range to maintain seal integrity.
