Abstract: A lifting system with stable and synchronized lifting operation is disclosed. The lifting system includes a plurality of lifting units, wherein the plurality of lifting units are configured to vertically translate a load in a synchronous action and each of the plurality of lifting units includes a support column configured to vertically extend and retract as a function of a lifting command, a lift plate detachably mounted on the support column, a base assembly configured to support the support column on a ground surface and an anti-tip mechanism configured to provide mechanical resistance to rotational displacement of each lifting unit relative to a ground surface and a system controller configured to receive a user input, generate the lifting command as a function of the user input and transmit the lifting command to each of the plurality of lifting units.

Abstract: A trailer with elevating bed is disclosed. A bed elevation assembly has elevation actuators quadrilaterally disposed and attached to frame members of a bed assembly and a chassis assembly of the trailer. The chassis assembly includes an axle mount, an axle attached at the axle mount, wheels operably attached to opposing ends of the axle, and a towing tongue for towing the trailer. The quadrilaterally disposed elevation actuators stabilize the bed assembly during movement from a nested position to an elevated position and when the bed assembly is held in the elevated position.
