How Strong Are They?

In a purely unscientific test, a 2.75" thick 24" x 24" pad was put into a test frame. The pad was supported for 3.5" of two sides, leaving the center (71%) unsupported. A 14" steel plate was placed on the pad. The pad was able to sustain, without any damage, 50 tons of pressure. (See diagram)

Keep in mind that no outrigger pad or crane mat can give a total assurance of safety. Additional cribbing must be used at times, even on flat asphalt surfaces. If the foot of the outrigger is small, a smaller pad should be used on top of the larger pad to spread the weight load.
