Abstract
A scissor lift includes a base, a platform, a plurality of pivotally connected scissor links, a support column, and a locking actuator. The platform has a fixed horizontal orientation and being movable between a first elevation and a second elevation. The scissor links are arranged in a crisscross pattern and operatively connecting the base and the platform. The lift actuator is pivotally attached to at least one of the scissor links to selectively raise and lower the platform along a lift path. The support column extends alongside the lift path and positioned adjacent to the platform. The locking actuator is fixed to an underside of the platform and includes 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.
