Round Outrigger Pad

Round outrigger pads for cylindrical feet

Boom lifts, spider cranes, and MEWPs mostly land on round outrigger feet, and a round pad seats them better than a square one — the load sits central instead of overhanging a corner. These outrigger pads — also known as outrigger plates or outrigger foot pads — come 12–48 in (300–1200 mm) in diameter to spread the foot load over soft ground and stop the leg punching in.

Roll it, don’t carry it

A 36 or 48 in pad is awkward to carry flat but easy to roll on edge like a wheel, so one operator moves it around the machine and stows it on the truck without a lift — no crew needed to shift it the way flat outrigger boards demand. At 3/4–2 in thick it is light enough to handle yet stiff enough to spread pressure without dishing under the float.

Sizing to the lift

Size the same way as any pad — whether you call them stabiliser pads or outrigger jack pads: outrigger load ÷ ground bearing pressure sets the diameter you need. Vertical working load limit runs from about 6 t on the smaller discs to roughly 90 t on the largest, covering service-vehicle jacks through to small mobile cranes. On very weak ground, step up a size rather than risk a leg settling mid-lift — see the crane outrigger pads sizing guide.

Where it suits

Spider and boom-lift outriggers, small mobile cranes, bucket trucks (outrigger pads for bucket truck duty), and service-vehicle stabiliser jacks. These round outrigger pads — sometimes called outrigger mats — seat cylindrical feet best; for the larger floats and spreader feet of bigger mobile cranes, the square crane outrigger pad gives more area and a flatter seat.
