A movable frame is adapted to be loaded onto and unloaded from a stationary frame mounted on a vehicle. A platform is releasably mountable onto said movable frame. The platform and movable frame may be hoisted simultaneously when being loaded and unloaded from the stationary frame. The platform includes a downwardly depending support legs which are of sufficient length to maintain the platform elevated above a first portion of the movable frame which is inserted under said platform when said movable frame is resting in a lowered position when unloaded from the stationary frame. The movable frame may be raised to engage with the underside of said platform. Interlocks cooperate between said platform and said movable frame so that the movable frame centers onto and mates with said underside of said platform.

A lift device includes a chassis, a rear leveling assembly coupled to a rear end of the chassis, and a front leveling assembly coupled to a front end of the chassis. The rear leveling assembly includes a first rear actuator and a second rear actuator. The first rear actuator and the second rear actuator are selectively engageable to facilitate providing active control of a rear pitch adjustment and a rear roll adjustment of the rear leveling assembly. The front leveling assembly includes a first front actuator and a second front actuator. The first front actuator and the second front actuator are (i) selectively fluidly couplable to facilitate providing passive control of a front pitch adjustment and a front roll adjustment of the front leveling assembly and (ii) selectively fluidly decouplable to facilitate providing active control of the front pitch adjustment and the front roll adjustment of the front leveling assembly.
