18 MPa Working Pressure, 27 MPa Maximum \u2014 What the Two Pressure Ratings Mean<\/h2>\n

The HCYY11112003 lifting cylinder carries two pressure ratings: 18 MPa working pressure and 27 MPa maximum withstand pressure. These are not alternatives \u2014 they serve different engineering functions, and both matter for the safety of a personnel-carrying aerial work platform.<\/p>\n

\"HCYY11112003<\/p>\n

\n
\n

18 MPa \u2014 Working Pressure<\/h3>\n

The maximum continuous pressure the lifting cylinder operates at during normal use. The hydraulic pump and relief valve are set to deliver up to 18 MPa to the cylinder during platform raising. At this pressure, the \u03a665 bore produces approximately 59.7 kN (6.1 tonnes-force) of extension force \u2014 sufficient to raise the platform, structure, and rated personnel load through the full stroke of 840 mm. The cylinder is designed to operate at this pressure for the full service life of the machine without fatigue or seal degradation.<\/p>\n<\/div>\n

\n

27 MPa \u2014 Maximum Withstand Pressure<\/h3>\n

The highest pressure the cylinder housing, rod, seals, and ports can safely withstand without permanent deformation or seal damage. This is 1.5\u00d7 the working pressure \u2014 the standard proof test ratio for hydraulic cylinders. Transient pressure spikes can occur during operation (for example, if the platform is loaded beyond its rated capacity, or if the lowering valve closes abruptly during descent). The 27 MPa rating ensures these spikes do not cause cylinder failure. Korea Ever-Power proof-tests every HCYY11112003 at 27 MPa before shipment.<\/p>\n<\/div>\n<\/div>\n

Why OEM Part Number Ordering Matters for Aerial Work Vehicle Cylinders<\/h2>\n

On a forklift, installing a cylinder with slightly different dimensions may result in reduced performance but the machine remains operational. On an aerial work vehicle that carries personnel at height, dimensional mismatches have safety consequences. A lifting cylinder with incorrect stroke means the platform does not reach full height \u2014 or the safety interlock prevents operation entirely. A cylinder with a lower pressure rating may not hold the platform weight at full extension. The HCYY part number eliminates dimensional ambiguity: when you order HCYY11112003, Korea Ever-Power manufactures a cylinder matched to the OE specification on every dimension.<\/p>\n

\n
\n

The Aftermarket Challenge<\/h3>\n

AWV dealer networks may not carry hydraulic cylinders in stock \u2014 these are low-volume, high-value items. When a lifting cylinder fails, ordering from the OEM factory can add 4\u20138 weeks. During that time, the aerial work vehicle is grounded, and the lost rental revenue or project downtime can exceed the cylinder’s replacement cost.<\/p>\n<\/div>\n

\n

The Korea Ever-Power Solution<\/h3>\n

Korea Ever-Power holds the HCYY11112003 dimensional data (\u03a665\u00d7\u03a645\u00d7840, 18\/27 MPa, 1075 mm installation distance, 27 kg) in its validated database \u2014 no engineering review delay. Typical lead time: 2\u20133 weeks for a single unit. For fleet operators, annual blanket agreements with planned call-off scheduling provide the shortest lead times and the best unit pricing.<\/p>\n<\/div>\n<\/div>\n<\/section>\n

<\/p>\n

\n

The Lifting Cylinder’s Role on an Aerial Work Vehicle<\/h2>\n

The lifting cylinder is the primary actuator on any aerial work vehicle \u2014 it converts hydraulic energy into the vertical height that gives the machine its purpose. On a scissor-type AWV, the HCYY11112003 lifting cylinder pushes the base of the scissor linkage outward, unfolding the mechanism and raising the platform. The 840 mm stroke translates through the scissor geometry into several metres of vertical platform rise, depending on the number of scissor stages.<\/p>\n

\"hydraulic-cylinder-1-3\"<\/p>\n

The lifting cylinder is also the first cylinder tested during the mandatory pre-use safety inspection required by EN 280 and ANSI A92 for all mobile elevating work platforms that carry personnel. The inspector checks for external oil leakage, rod surface damage, and platform drift under load \u2014 all of which indicate lifting cylinder condition. A cylinder that fails this inspection grounds the machine until it is repaired or replaced. Keeping a replacement HCYY11112003 on the shelf \u2014 or having a supplier who can deliver in 2\u20133 weeks \u2014 directly reduces downtime when the inspection identifies a cylinder that needs replacement.<\/p>\n<\/section>\n

HCYY11112003 Lifting Cylinder \u2014 Technical Questions<\/h2>\n
\n
\n

Is the HCYY11112003 the same cylinder as the HCYY11112006?<\/h3>\n

No. Both are lifting cylinders for aerial work vehicles, but they serve different AWV models with different dimensional specifications. The HCYY11112003 is \u03a665\u00d7\u03a645\u00d7840 at 18 MPa; the HCYY11112006 has different dimensions for a different platform. Always order by the exact part number stamped on the cylinder you are replacing.<\/p>\n<\/div>\n

\n

Can I order the HCYY11112003 together with other HCYY AWV cylinders for a complete overhaul?<\/h3>\n

Yes \u2014 and this is recommended for major service. Order the full set of HCYY AWV cylinders for your specific platform in one order. All are manufactured on the same production line, with the same seal brand, in the same batch. Shipped in one consolidated crate, reducing shipping cost. Total installation time for a complete cylinder overhaul is 1\u20132 days \u2014 far more efficient than replacing cylinders individually over months as they fail one by one.<\/p>\n<\/div>\n

\n

What seal upgrade do you recommend for dusty construction-site use?<\/h3>\n

For outdoor use in dusty or abrasive environments, specify Parker or Hallite PTFE rod seals. Standard polyurethane seals last 3,000\u20135,000 hours in clean indoor environments but may wear in 1,500\u20132,500 hours on construction sites. PTFE rod seals have significantly better abrasion resistance and can extend the service interval to 4,000\u20136,000 hours in the same conditions. Contact Korea Ever-Power<\/a> with your operating environment for a specific seal recommendation.<\/p>\n<\/div>\n

\n

What does the 27 MPa maximum withstand pressure mean in practice?<\/h3>\n

It means the HCYY11112003 is proof-tested at 27 MPa (1.5\u00d7 the 18 MPa working pressure) before shipment. This test confirms the housing, seals, and rod can survive transient pressure spikes without leakage or deformation. In daily use, the cylinder should never reach 27 MPa \u2014 the system relief valve limits the pressure to approximately 18\u201320 MPa. If the working pressure regularly exceeds 18 MPa, the hydraulic system has a fault (typically an overloaded platform or a relief valve set too high) that should be diagnosed before the cylinder is stressed beyond its design intent.<\/p>\n<\/div>\n<\/div>\n<\/section>\n

We operate 8 scissor lifts in a logistics park. The lifting cylinder on unit #3 started leaking at about 4,800 hours. The OEM dealer quoted 6 weeks and a premium price. Contacted Ever-Power \u2014 they confirmed the HCYY11112003 dimensions (\u03a665\u00d7\u03a645\u00d7840) within a day and delivered in 18 days. Perfect fit. Drift test passed with zero measurable descent at rated load. We’ve since ordered the steering cylinder (HCYY11112004) for unit #5 \u2014 same experience. Planning to consolidate all HCYY cylinder replacements with Ever-Power going forward.<\/p>\n<\/div>\n

We rent out AWVs across the UAE. The lifting cylinders are our #1 replacement item \u2014 the construction dust in this region is brutal on rod seals. We asked Ever-Power to build the HCYY11112003 with NOK FKM seals for better dust and heat resistance. Seal life improved from approximately 2,500 hours to over 5,000 hours so far and still going. We’ve ordered 6 units over the past 4 months. The HCYY part number ordering is simple \u2014 no ambiguity, just quote the number and receive the correct cylinder.<\/p>\n<\/div>\n

Good cylinder, correct dimensions, works as expected on our scissor platform. Delivery took 24 days to S\u00e3o Paulo \u2014 a bit longer than the 2\u20133 weeks quoted, but still much faster than the OEM channel which quoted 8+ weeks. Product quality is solid. Four stars because of the delivery variance \u2014 the cylinder itself deserves five.<\/p>\n<\/div>\n
