A vehicle built-in electric jack system, including a plurality of electric jacks capable of lifting a vehicle. The plurality of jacks operates using a 12-volt power supply. The plurality of jacks are telescopic jacks. Each jack is made from a plurality of cylinders. The cylinders are apportioned such that each cylinder for a jack fits inside of the previous cylinder. Each of the plurality of jacks has a minimum of one light placed on the jack. The light is directed toward the wheel well of the vehicle. The jacks and lights are attached to a controller. The controller is located inside of the vehicle such that the jacks and lights can be operated while the user is inside of the vehicle cab. Further, each jack has a rocker switch located thereon that can control the jack to which it is attached.

An automatic tire replacement apparatus is disclosed that has an electric motor with a drive shaft and a first gear concentrically connected to the drive shaft. The first gear may connect to a symmetrical bolt locking gear array having several bolt locking gears arranged such that each bolt locking gear rotates in the same direction that the first gear rotates. Each bolt locking gear may have a cylindrical hole at its center. The cylindrical hole may be outlined with an inner spiral thread, which connects to a set of power bolts that are outlined in an outer spiral thread which interlocks with the inner spiral thread.

A fire apparatus includes a chassis, a body assembly, a front cabin, a front axle, at least one rear axle, a ladder assembly having a proximal end that is coupled to the chassis between the front axle and the at least one rear axle, a stability system, and a controller. The stability system includes a pair of front downriggers, a pair of rear downriggers, and an outrigger assembly coupled to the chassis between the front axle and the at least one rear axle. The front and rear downriggers are selectively extendable to engage a ground surface. The outrigger assembly includes a pair of outriggers that are selectively extendable from the body assembly to engage the ground surface. The controller is configured to facilitate controlling extension and retraction of the front downriggers, the rear downriggers, and the outriggers to lean the fire apparatus.

A vehicle leveler spacer and method of using the vehicle leveler spacer that may be selectively attached to a retracted leveler of a vehicle, such as a trailer or motor home. The spacer at least partially supports the vehicle upon extension of the leveler to the ground. The spacer includes at least one connector to selectively connect the spacer to the retracted leveler. The connector may be a magnet, strap, clamp, or another mechanical connector. The top surface of the spacer may include a rim along its perimeter configured to retain a pad of a leveler. The spacer may form a gap between the bottom surface and a supporting surface, e.g. the ground, when the spacer is connected to a retracted leveler. The connectors enable the spacer to be quickly attached or removed from a retracted leveler of a vehicle.

Embodiments of the present disclosure include a trailer assembly for transporting a plurality of proppant containers along a roadway, and associated methods. The trailer assembly includes a skeletal frame having open areas between structural components to enhance weight reduction of the frame, and first, second, third, and connector sections. Additionally, the frame includes a pair of spaced-apart side rails and three or more wheel and axle assemblies to facilitate movement of the trailer assembly. The trailer assembly includes a first pair of outriggers coupled to and arranged transverse the pair of side rails, and a second pair of outriggers arranged proximate the first pair of outriggers. The outriggers have a coupling element positioned at each distal end to engage and secure a proppant container of the plurality of proppant containers to the trailer assembly. Each distal end is positioned to extend outwardly from an axis of the trailer.
