A welding table with elevation system, powered with cordless drill, gear reducer, chain, sprockets and, ultimately turning screw posts synchronously, lifting four telescoping legs. Maximum elevated height exceeds most work benches for height matching, and a minimum height goes lower than most low tables. Folding wheel system is independent, lever operated, and works in conjunction with the elevation system. Once table rolls into position, drill is activated, braking is instant, the table lifts itself from the wheels. Wheels are then folded up, a position necessary during minimum height, as the frame gets closer to the ground. This low height enables sitting roll stool usage, and knees and legs enter the rear frame opening. Two drawers above conceal the wheels, have a lever locking system, and necessary when rolling the table. The table top is heavy, one piece removable with normal modular patterned holes throughout, and the addition of large oval holes, and top side overhang, both establishing C-Clamp usage.

A server rack including a bottom panel, a top panel opposite to said bottom panel, a plurality of housing units configured for receiving rack-mountable equipment, the plurality of housing units being horizontally side-by-side arranged between the top panel and the bottom panel, the bottom panel comprising two support rails for supporting the server rack.

A mobility apparatus. The mobility apparatus may include a continuous fixed-length rail attached horizontally to a bottom structural member of the front or the rear of a server rack. The continuous fixed-length rail exceeds a width of the server rack by an equal amount on either side of the server rack. The mobility apparatus also includes a lower rail portion attached to a lower edge of the continuous fixed-length rail; a raised rail portion attached to an extended length of each portion of the continuous fixed-length rail; and at least one wheel attached to an underside of each end of the extended length of the continuous fixed-length rail.

An adjustable caster assembly includes a body having a top surface and a base, and an opening within the base. A wheel is connected to the body, where the wheel is configured to extend beyond the base of the body to engage a supporting surface. A foot is positioned within the opening in the base and configured to move between an expanded position and a contracted position. The foot may be actuated by an actuation shaft that engages a gear. The actuation shaft may be movable between an engaged position and a disengaged position.

A removable caster system includes a roller, a roller frame and a roller seat, the roller being positioned on the frame via a horizontal axis, the frame being inserted into the vertical shaft hole of the seat through the vertical shaft to form a detachable position; wherein a chute is installed on the upper surface with a trapezoidal stopper; a wire retainer is placed in the chute and is controlled by the movement of its narrowing section or the vertical axis to achieve removable function.

Maneuverable ergonomic trailer stands are disclosed. An example portable trailer stand includes: an elongate upper ledge, a post coupled to the upper ledge, an extendible leg telescopically coupled to the post, the upper ledge being vertically movable to selectively engage and disengage an underside of a trailer based on movement of the extendible leg relative to the post, and a plurality of wheels coupled to the post, the post to maintain the plurality of wheels at a substantially fixed distance from the upper ledge as the upper ledge is vertically moved, each of the plurality of wheels to be equidistant from a vertical axis traversing through a center of the upper ledge.

Mobile folding restaurant booth style benches are provided, which may be arranged in opposed pairs to form restaurant style booths. An individual bench incorporates a mechanism for shifting the weight of the bench between a mobile base, which may be supported by swivel casters, and a stationary base, which may be supported by non-slip feet, actuated by pivoting a bench seat down from a folded storage position to an unfolded seating position. The weight shifting mechanism may include an engagement member, which is initially spaced apart from an actuator at a folded angle of the seat, and which contacts and begins transmitting force and movement to the actuator at a partially unfolded angle of the seat. Preferably, the bench further includes a biasing component that biases the stationary base upward relative to the mobile base.
