Hydraulic Cylinder Solutions \u00b7 United Kingdom<\/p>\n

Hook-Lift Truck Locking Cylinder \u2014 High-Pressure Hydraulic Lock for Environmental & Industrial Applications<\/h2>\n

The locking cylinder HCYY11112013 (\u03a640\u00d7\u03a620\u00d7200) is a compact, high-integrity hydraulic actuator engineered for applications where positional lock and pressure retention are non-negotiable. Rated at 30 MPa working pressure and a maximum withstand pressure of 37 MPa, this unit delivers the structural confidence that British environmental protection equipment manufacturers, waste processing plants, and industrial automation integrators demand from a reliable hydraulic locking cylinder supplier. With an installation distance of 370 mm and a net weight of just 4.2 kg, it combines lightweight construction with heavy-duty performance \u2014 a balance rarely achieved without precision manufacturing.<\/p>\n

What Makes a Locking Cylinder Different From Standard Hydraulic Cylinders?<\/h2>\n

A locking cylinder is not simply a conventional actuator with a brake bolt added on. The internal architecture is purpose-designed to hold a load in mid-stroke without relying on continuous hydraulic pressure \u2014 a feature that separates it from ordinary double-acting cylinders used in generic motion control. Inside the HCYY11112013, a mechanically-engaged locking ring or toothed collar engages automatically when hydraulic pressure is released, clamping the rod at its current position and preventing any drift under gravity or external axial force. This mechanical interlock is the heart of the design: it means that even in the event of a circuit failure, pressure drop, or emergency shutdown, the attached structure \u2014 whether a refuse collection arm, a telescopic flap, or a sorting gate on a waste processing line \u2014 stays precisely where it was commanded to go. For UK integrators working under the Pressure Equipment (Safety) Regulations 2016 and the Machinery Directive successor frameworks, this passive fail-safe architecture is an increasingly important compliance consideration rather than simply a nice-to-have engineering feature.<\/p>\n

The bore and rod combination of \u03a640\u00d7\u03a620 positions this cylinder in the compact-force segment \u2014 powerful enough to actuate lids, doors, panels, and small structural arms in environmental protection machinery, yet small enough to fit inside densely packaged equipment chassis where space is at a premium. The 200 mm stroke is typical for mechanisms requiring full-travel lock in the extended or retracted state, and the 370 mm installation distance makes layout planning straightforward for mechanical designers working in CAD.<\/p>\n<\/div>\n

Technical Specification \u2014 Locking Cylinder HCYY11112013<\/h2>\n

The table below reflects the original factory data sheet for the HCYY11112013 locking cylinder. All dimensional values are in millimetres unless otherwise stated. Engineers selecting this unit for integration into UK environmental or industrial plant should note the 37 MPa burst-containment ceiling \u2014 this leaves a meaningful safety margin above the 30 MPa operational working pressure even under pressure spike conditions.<\/p>\n

\u2699 Operating Principle<\/h3>\n

Hydraulic pressure drives the piston rod to the target position. On pressure release, a spring-loaded or hydraulically-piloted locking collar engages the rod grooves mechanically, holding the position without any continuous oil supply. To release, pilot pressure is applied to the unlock port, disengaging the collar before the next actuation cycle begins. The system is fully bidirectional \u2014 locking can be set to occur at full extension, full retraction, or any intermediate point depending on porting configuration agreed at order stage.<\/p>\n<\/div>\n

\ud83d\udd28 Construction & Materials<\/h3>\n

The cylinder barrel is machined from seamless cold-drawn steel tube, honed to Ra 0.4 \u00b5m internal finish. The piston rod is 45 steel (or equivalent EN8 specification) with hard-chrome plating to a minimum 25 \u00b5m depth for corrosion and wear resistance in outdoor environments. End caps are forged or machined from structural carbon steel with high-pressure rated thread forms. All internal seals are polyurethane (PU) and PTFE-based, rated for mineral oil, biodegradable oil, and standard hydraulic fluid compatibility across the -20\u00b0C to +80\u00b0C operating temperature range.<\/p>\n<\/div>\n
