ABSTRACT:
An improved float pad mounting is disclosed for releasably connecting the float pad to an outrigger lift jack shaft. The lift jack can be activated to move the shaft between a retracted position for outrigger travel and extended positions grounding the float pad for stabilized outrigger support. The float pad has a base of large area and a central hub upstanding from the base. Cooperating hemispherical surfaces are formed between the shaft and the hub which become engaged in the extended positions to transmit the outrigger load to the float pad base. An annular collar surrounds the shaft, and a pin extended through aligned openings in the collar and shaft secures the collar to the shaft at a location slightly above the load transmitting surface. Two closed links are loosely connected to the collar at 180.degree. spacings around the center axis of the shaft, and two lugs are formed on the float pad hub at like 180.degree. spacings around said hub. Each respective link is adapted, with the load carrying surfaces engaged, to fit over one of said lugs to allow for the link connection to or separation from said lug. Hairpin means releasably fit through an opening in each lug outboardly of said link from said hub and preclude accidental separation of the positioned link from the lug. Each lug has a recessed lower edge facing the base which abuts the link when the load engaging surfaces are separated incidental to the shaft being retracted.
