Heavy-Duty Long-Stroke Lifting Cylinder for Boom Lift
Model HCYY11112006 · Φ65×Φ45×1260 · 18MPa Working Pressure · 1260mm Stroke — engineered for aerial work platforms operating across the UK and Europe.
When a boom lift has to raise personnel or equipment to significant heights without hesitation, the lifting cylinder is the component that decides whether the job gets done safely. The Heavy-Duty Long-Stroke Lifting Cylinder for Boom Lift — model HCYY11112006, specification Φ65×Φ45×1260 — has been engineered for exactly this kind of uncompromising application. With a rated working pressure of 18 MPa and a maximum withstand pressure of 27 MPa, this lifting cylinder delivers controlled, repeatable extension across its full 1,260 mm stroke length, even when operating in the variable-load conditions that characterise real construction, maintenance, and utilities work in the United Kingdom. The rod diameter of Φ45 mm and bore of Φ65 mm have been sized to balance column strength against weight, keeping the aerial platform responsive and balanced. Installation distance is 1,629 mm and finished weight is 54 kg — dimensions that integrate cleanly with the structural envelopes of modern boom lift designs without requiring platform redesign.
Whether you are outfitting a new fleet of aerial work vehicles, replacing a worn lifting cylinder in an ageing platform, or sourcing components for an OEM production run, this product is available with full technical documentation, custom rod-end configurations, and short lead times shipped directly to UK customers.
How This Lifting Cylinder Works
The HCYY11112006 is a double-acting hydraulic cylinder. When pressurised hydraulic oil enters the cap-end port, it pushes the piston forward, extending the rod and raising the boom. When the rod-end port receives oil under pressure, the piston retracts, lowering the platform in a controlled, metered manner. This bidirectional control is critical for boom lifts because operators must be able to position the platform at any intermediate height — not simply raise or lower it to the extremes of travel.
The cylinder body is produced from seamless cold-drawn steel tubing with a honed internal bore tolerance that keeps leakage past the piston seal to an absolute minimum. The rod is precision-ground, hard-chrome plated and polished to Ra ≤ 0.4 µm, ensuring the rod seal experiences consistent, predictable surface contact rather than the micro-scoring that shortens seal life in lower-grade products. A composite wiper seal at the gland end clears particulate contamination from the rod surface on every retraction stroke, protecting the internal seal from the dirt and moisture that are unavoidable on UK construction sites.

Typical Application Scenarios in the UK Market
The HCYY11112006 lifting cylinder was designed for the kind of demanding duty cycles that aerial work platform operators in the United Kingdom know well. A boom lift on a construction site in Birmingham may cycle its platform dozens of times per shift across a twelve-hour day. A telecoms maintenance crew working on mast structures in rural Yorkshire requires a lifting cylinder that holds position for extended dwell periods without thermal creep. A facilities management company maintaining the glazing on a commercial building in central London needs smooth, low-speed controllability right through the final few centimetres of extension. This cylinder addresses all three scenarios.

Customer Success Cases
A regional plant hire company based in the West Midlands operates a fleet of 35 articulated boom lifts serving construction contractors across the English Midlands. After experiencing recurring seal failures in their previous lifting cylinders — particularly during winter when temperatures in Birmingham drop below 5°C — they trialled six HCYY11112006 units with low-temperature seal specification. Over 14 months of operation with no unplanned maintenance stops directly attributable to cylinder failure, they converted their entire fleet to our lifting cylinders.
A German contractor specialising in mobile network infrastructure maintenance operates aerial work platforms across Germany and the Netherlands. Their previous lifting cylinders showed measurable positional drift when platforms were held stationary at height during long-duration inspections — a safety concern for personnel working aloft. After switching to HCYY11112006, the combination of tight bore tolerances and quality piston seals eliminated drift under static load conditions. They placed a volume order covering 22 replacement units and have since specified our cylinder as their preferred replacement part.
An Australian OEM manufacturer producing compact articulated boom lifts for the domestic construction and resources sectors needed a long-stroke lifting cylinder that could be customised to their specific pin bore dimensions and port thread pattern. After providing detailed drawings, our engineering team produced a modified variant of the HCYY11112006 with custom clevis ends and BSPP port threads. First-article inspection passed on the initial sample batch, and they have since placed quarterly production orders covering 80 to 120 units per quarter, delivered on a scheduled basis to their Queensland assembly facility.
Manufacturing Facility & Custom Engineering Capability
Our hydraulic cylinder manufacturing facility operates a dedicated production line for aerial work platform components. CNC honing machines maintain bore tolerance to IT8 grade across every cylinder barrel we produce. Laser-guided rod grinding cells hold rod diameter to h6 tolerance consistently across production runs of any scale. The facility is ISO 9001 certified, and our quality management system includes incoming material certification, in-process dimensional inspection, and a hydrostatic pressure test on every finished unit before despatch.
Custom engineering is a core capability rather than an exception. We regularly produce modified variants of the HCYY11112006 and related cylinders for OEM customers who require different rod end styles, modified port positions, alternative seal compounds, special surface treatments, or dimensional changes to match existing structural envelopes. Drawing review to first-article delivery typically runs four to six weeks depending on complexity. Volume production lead times for established designs are two to three weeks from order confirmation, with air freight options available for UK customers with urgent requirements.
