ABSTRACT:
A sliding suspension includes a plurality of locking pins that are selectively moved between extended and retracted positions to allow adjustment of the sliding suspension relative to a trailer frame structure. A lever is fixed to a tube that is supported by a cross-member of a slider frame. A cam is supported on the tube for rotational movement relative to the tube. Laterally spaced locking pins each include a pin connection link that is coupled to the cam. Each locking pin includes a single compression spring, and each pin connection link includes a slot, which cooperate with each other to provide independent pin extension at each pin location. A torsion spring is coaxial with the tube and includes one spring end that is coupled to the lever and another spring end that is coupled to the cam. The torsion spring allows the lever to be decoupled from the locking pins if one or more pins are stuck such that the pull handle can be pulled and locked into place to allow adjustment.
