Claim:
1. A scissor lift comprising: a base; a platform having a fixed horizontal orientation and being movable between a first elevation and a second elevation; a plurality of pivotally connected scissor links arranged in a crisscross pattern and operatively connecting the base and the platform; a lift actuator pivotally attached to at least one of the scissor links to selectively raise and lower the platform along a lift path; a support column extending alongside the lift path and positioned adjacent to the platform; a locking actuator fixed to an underside of the platform, the locking actuator comprising a piston member extendable toward the support column to operatively connect the platform with the support column when the platform is raised at the second elevation so that the platform is supported by the support column in the fixed horizontal orientation; and a locking receptacle carried by the support column, wherein the piston member is received within the locking receptacle when the platform is operatively connected to the support column, wherein each of the plurality of the scissor links pivots about a first axis of a plurality of respective first axes and the piston member moves reciprocally along a second axis, wherein the second axis is not parallel with any of the first axes.
