Rotary Actuator<\/h2>\n

The only true rotary actuator in 31 products. Not a cylinder with a linkage \u2014 a vane or gear mechanism that produces rotation directly. 360\u00b0 of continuous swing from a compact housing that fits inside the boom knuckle joint. The final product in Korea Ever-Power’s mobile machinery range.<\/p>\n

Product #5 (small excavator rotary actuator) carries the name “rotary” but is actually a linear cylinder connected to a swing linkage \u2014 the cylinder pushes a lever arm, and the lever arm rotates the boom. This works for the excavator’s limited \u00b130\u00b0 offset angle, but it cannot produce continuous 360\u00b0 rotation, and the packaging is too bulky for the tight knuckle joints of an aerial platform boom.<\/p>\n<\/div>\n

Product #16 is genuinely rotary: a vane or gear set inside a cylindrical housing converts hydraulic pressure directly into rotational torque. The output shaft rotates \u2014 no linkage, no lever arm, no angular limitation. The compact cylindrical housing bolts directly into the boom knuckle joint or basket pivot, producing smooth 360\u00b0 rotation from a package that occupies 30\u201350% less volume than a cylinder-and-linkage arrangement producing the same torque.<\/p>\n

Korea Ever-Power manufactures the rotary actuator as the seventh and final product in the aerial work platform hydraulic cylinder<\/a> range \u2014 and the 31st and final product in the complete mobile machinery catalogue.<\/p>\n

Vane vs Gear \u2014 Two Mechanisms for Different Torque Ranges<\/h2>\n
\n
Vane type \u2014 compact, 500\u20132,000 Nm<\/strong><\/p>\n

A single or double vane inside a cylindrical housing swings under hydraulic pressure, producing torque proportional to the vane area \u00d7 pressure \u00d7 radius. Vane actuators are compact and lightweight \u2014 ideal for platform basket swing and jib rotation on smaller boom lifts. Single-vane designs achieve 360\u00b0 continuous rotation; double-vane designs produce 2\u00d7 torque but limit the angle to 90\u2013180\u00b0.<\/p>\n<\/div>\n

Gear type \u2014 robust, 2,000\u20135,000 Nm<\/strong><\/p>\n

A rack-and-pinion or helical gear mechanism converts the linear force of an internal piston into rotary output. Gear actuators handle higher torque and greater shock loads than vane types \u2014 suitable for heavy crank arm swing on large articulating booms. The gear mechanism also provides more precise angular positioning (\u00b10.5\u00b0) than vane types (\u00b11\u20132\u00b0).

Manufacturing Process<\/span><\/h2>\n

Vane actuators: the housing bore is honed to Ra 0.2\u20130.4 \u00b5m \u2014 the vane tip seals against the bore, so the bore finish directly affects internal leakage and torque efficiency. Vane-tip seals are PTFE-composite for low friction and 20,000+ hour life. Gear actuators: the rack is precision-ground and induction-hardened; the pinion is carburised steel; mesh backlash \u22640.05 mm for precise angular positioning.<\/p>\n

Both types are hydrostatic tested at 1.5\u00d7 rated pressure (31.5 MPa) and torque-tested at rated pressure \u2014 verifying that output torque matches the specification within \u00b15%. Every rotary actuator is swing-tested for smooth 360\u00b0 rotation (vane) or full-angle rotation (gear) without stick-slip, cogging, or torque ripple.<\/p>\n<\/section>\n

FAQ<\/span><\/h2>\n
\n
\n

How does this differ from the excavator rotary actuator (#5)?<\/h3>\n

#5 is a linear cylinder connected to a swing linkage \u2014 it converts linear motion to rotation through an external mechanism and is limited to approximately \u00b130\u00b0 of boom offset. #16 is a true rotary device \u2014 the internal vane or gear produces rotation directly, achieving continuous 360\u00b0 swing in a compact housing. The true rotary design is smaller, smoother, and unrestricted in angle.<\/p>\n<\/div>\n

\n

Why only 21 MPa \u2014 lower than the other AWP cylinders at 30 MPa?<\/h3>\n

The torque requirement for platform basket swing (500\u20135,000 Nm) is modest compared to the linear force requirements of the luffing, telescopic, and outrigger cylinders. 21 MPa standard pressure produces adequate torque from the vane\/gear geometry without requiring the heavier housings, seals, and port fittings needed at 30 MPa. The lower pressure also reduces seal wear and extends service life \u2014 important for a component that operates continuously during every basket repositioning movement.<\/p>\n<\/div>\n

\n

Can Korea Ever-Power supply the complete 7-product aerial platform set?<\/h3>\n

Yes \u2014 electric cylinder (#10), luffing (#11), outrigger (#12), telescopic (#13), leveling (#14), steering (#15), and rotary actuator (#16) are available as a complete matched system for aerial platform OEMs. This final product completes the 31-product Korea Ever-Power mobile machinery hydraulic cylinder catalogue \u2014 spanning 6 equipment categories from small excavators to mining dump trucks to aerial work platforms.
