Aerial Work Platform Outrigger Cylinder<\/h2>\n

No boom until all four are down. The aerial platform’s safety interlock will not enable the boom controls until every outrigger cylinder reports ground contact and the chassis is level. This is not a guideline \u2014 it is a safety standard requirement. The outrigger cylinder is the gatekeeper between a parked platform and a working platform.<\/p>\n

Interlock \u2014 The Boom Cannot Move Until the Outriggers Confirm<\/span><\/h2>\n
\n \"Aerial<\/p>\n

On a mobile crane, the operator can choose to work with partial outrigger extension at reduced capacity \u2014 the load chart has columns for different outrigger configurations. On an aerial work platform, the safety standard does not permit this. EN 280 and ANSI A92 require that all outriggers are fully deployed, ground contact is confirmed (typically by a pressure switch or proximity sensor on each outrigger cylinder), and the chassis is level (within 1\u20133\u00b0 of horizontal) before the boom control circuit is energised.<\/p>\n<\/div>\n

The outrigger cylinder’s position sensor (or pressure switch) provides the confirmation signal to the platform’s interlock system. If any outrigger is not fully deployed, or if any outrigger loses ground contact during operation (indicating ground settlement), the interlock disables boom motion \u2014 the platform freezes in position until the operator returns the outrigger condition to the safe state.<\/p>\n

Korea Ever-Power manufactures the outrigger cylinder with integrated sensor provisions as the third of seven aerial work platform hydraulic cylinders<\/a>.<\/p>\n<\/section>\n

Auto-Level \u2014 The Outrigger Cylinder Levels the Chassis Automatically<\/h2>\n

Many modern aerial platforms include automatic levelling \u2014 the platform’s control system reads the chassis inclinometer and individually adjusts each outrigger cylinder to bring the chassis to within \u00b10.5\u00b0 of horizontal. The operator presses one button, and the system extends all four outriggers, senses ground contact, then fine-adjusts each leg independently until the chassis is level.<\/p>\n

\n
Proportional control \u2014 millimetre adjustment<\/strong><\/p>\n

Auto-levelling requires the outrigger cylinder to respond to small, precise valve commands \u2014 extending 1\u20135 mm at a time to fine-tune the chassis angle. This demands low breakaway friction (the cylinder must start moving at minimal valve opening) and smooth proportional response (the extension speed must be proportional to the valve opening, without stick-slip).<\/p>\n<\/div>\n

Ground contact sensing \u2014 the safety interlock signal<\/strong><\/p>\n

When the outrigger pad touches the ground, the cylinder pressure rises (the pad pushes against the ground, and the ground pushes back). A pressure switch on the cylinder port detects this rise and sends a “ground contact confirmed” signal to the interlock system. Alternatively, a proximity sensor detects the position of the pad. Korea Ever-Power machines the pressure switch port and\/or sensor mounting provisions directly into the cylinder barrel.

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

How does this differ from the crane outrigger cylinder (#19)?<\/h3>\n

Smaller bore (45\u2013200 vs 70\u2013360 mm \u2014 lighter platform), lower pressure (30 vs 42 MPa), but stricter safety integration: mandatory ground-contact sensor, safety interlock with boom controls, and auto-level capability. The crane outrigger has no interlock \u2014 the crane can operate with partial outrigger at reduced capacity. The aerial platform cannot \u2014 all outriggers must be confirmed before any boom motion is permitted.<\/p>\n<\/div>\n

\n

Why is the stroke up to 2,000 mm \u2014 longer than the crane outrigger’s 800 mm?<\/h3>\n

Many aerial platforms \u2014 especially spider lifts and track-mounted platforms \u2014 have outriggers that extend both horizontally (for wider footprint) and vertically (to push the pad down) using a single multi-function cylinder. The 2,000 mm stroke accommodates this combined horizontal + vertical motion. Some truck-mounted platforms also have outriggers that must reach down from a high chassis (1.5 m above ground) to the surface.<\/p>\n<\/div>\n

\n

Can Korea Ever-Power supply all 7 aerial platform cylinders as a set?<\/h3>\n
