Each wheel assembly includes an independently powered and steerable wheel configured to engage a travel surface, a propelling motor configured to drive a respective first support arm between a stowed condition and a deployed condition unaided while the vehicle remains stationary, and a steer actuator configured to change an angle of the wheel with respect to a respective support arm.

A delivery system includes a handheld electric lift configured to lift at least one vaporizer vessel, and a cabinet configured to hold the at least one vaporizer vessel. The lift includes an elongated mast, an effector attached to the mast, a handler configured to move the lift, and at least one caster. The effector is controlled by an electric power source to move along the mast. Each of the at least one caster includes a stopper and a wheel. The stopper is elongated and is disposed above the wheel. The stopper is configured to engage with the wheel to prevent the wheel from swiveling when the stopper is pushed down. The stopper is further configured to disengage with the wheel to allow the wheel to swivel when the stopper is released. The cabinet includes at least one channel configured to accommodate the at least one caster.

The present disclosure is a lift attachment apparatus for construction and farm equipment, including a loader. In an embodiment of the disclosure, lift apparatus may include a frame including an attachment device configured to attach to a tilting plane of a loader having a forward facing loader arm, a pair of wheels connected to the frame, a first wheel of the pair of wheels located on a first side of the frame and a second wheel of the pair of wheels located on a second side of the frame. The lift attachment apparatus may further include a boom or forks connected directly or indirectly to the frame, wherein control of the boom or forks is provided by application of force to the attachment device by the forward facing loader arm in a downward direction to create lift and rotation of the tilting plane causing rotation of an end of the boom or forks about the first wheel and the second wheel. The first wheel and second wheel being mechanically aligned to act as a stable fulcrum.

The present invention discloses a lifting mechanism mounted on a lifting device, wherein the lifting device includes a carrying unit. The lifting mechanism is disposed under the carrying unit, and comprises a driving assembly and a lifting assembly.
