In described embodiments, a trailer jack mount includes a first hinge plate mountable onto a frame of a vehicle. The first hinge plate has a first side hinge knuckle extending along a side of the first hinge plate and a first rear hinge knuckle extending along a length of the first hinge plate. A second hinge plate has a second side hinge knuckle hingedly connected to the first side hinge knuckle and a second rear hinge knuckle extending along a length of the second hinge plate. A locking bolt is removably insertable through the first rear hinge knuckle and the second rear hinge knuckle. The second hinge plate is rotatable between a first position wherein the second hinge plate is facing the first hinge plate and a second position wherein the second hinge plate is rotated away from the first hinge plate. In either the first position or the second position, the locking bolt is insertable through the first rear hinge knuckle and the second rear hinge knuckle to secure the first hinge plate and the second hinge plate in either the first position or the second position.

A lifting and lowering tool includes a foot configured to be supported on a surface, a bar extending therefrom, and a movable assembly including a housing, a movable platform shaped to support a load that extends from the housing, a lifting actuator configured to incrementally move the movable assembly along the bar away from the foot, a lowering actuator configured to incrementally move the movable assembly along the bar towards the foot, and a release actuator configured to disengage the movable assembly from the bar to allow free movement of the movable assembly along the bar. In embodiments, the movable assembly engages the bar through locking plates that extend through a flange of the movable assembly. In embodiments the release actuator is spaced from the lifting actuator and the lowering actuator to prevent inadvertent actuation of the release actuator. In embodiments a flange of the movable assembly surrounds the bar.
