Smaller cranes can do with a single set of outriggers mounted to the crane.  Larger cranes will require two sets of outriggers (also referred to as stabilizers).

We have the software in house to run the stability numbers for faster and more accurate quoting.  This software will tell you what you need to keep your unity stable.

Articulating Crane Outrigger Terminology

Outriggers: Mechanical extensions to the crane or truck which expand the foot print of the truck thereby increasing stability. The extensions may be manual or hydraulic powered and the vertical elements which make contact with the ground are typically hydraulically actuated.

Outrigger Extension Span: This is the overall outrigger reach from left to right measured from center of pad to center of pad. This is also referred to as the “footprint” of the crane.

Outrigger Pads: The vertical outriggers typically have a foot of small diameter onto which can be slid/attached either metal or plywood pads of larger area to reduce ground pressure. The pads may also be loose in nature and placed under the foot of the outrigger.
