A method of facilitating production of a structure at a construction site, the method including the steps of: a) obtaining a mobile apparatus having: a frame; first and second wheels and a steerable third wheel spaced in a fore and aft direction from the first and second wheels and laterally between the first and second wheels; and a platform on the frame defining a first upwardly facing surface that is spaced at least 20″ above the subjacent surface; b) placing at least one building component in a transporting position on the first upwardly facing surface; c) advancing the mobile apparatus from the first location to a second location at or adjacent the construction site; and d) separating the at least one building component from the transporting position at the second location.

A concrete/cement resurfacing machine integrates a dust collection subsystem and an overlay mixing/distribution subsystem, enabling a single operator to steer the machine to a desired floor location and deposit mixed, cementitious overlay material. The combination of dust collection and overlay mixing saves considerable time and achieves improved results, eliminating the need for separate vacuum machines while reducing the risk that dust will be released as bags of dry ingredients are added to the mixing tank. A single propane engine powers a hydraulic pump, with fluid being routed to three separate hydraulic motors with associated control valves to provide for forward/reverse locomotion, bidirectional paddle mixing, and vacuum generation. The dust collection system is preferably a two-stage system including a vacuum collection tank and a HEPA filter.

A pallet sled includes an upper frame including spaced-apart arms adapted to receive feet of a pallet therebetween. A lower frame supports the upper frame. A plurality of pivotable arms connect the lower frame to the upper frame. A handle is pivotably connected to the lower frame and the upper frame, such that pivoting the handle selectively raises and lowers the upper frame relative to the lower frame.

A pallet lift includes a base and a deck extending forward of the base. Load wheels support the deck. A platform above the deck is pivotable relative to the base. The platform has an upper support surface for supporting objects thereon. The platform may be pivoted as the pallet lift travels on an inclined surface, such as a truck ramp, in order to keep the platform relatively level relative to gravity to increase stability.

A handle assembly for a cart with a power assist function can sense the direction that a user's force is applied, and provide assist power in the corresponding direction, such that the user can easily move the cart. A cart including the handle assembly allows the user to conveniently move the cart.

A multi-terrain cart, comprising a cart body, two front and two rear non-pivoting wheels, a swivel wheel positioned forwardly or rearwardly to the front and rear non-pivoting wheels, respectively, an actuator for applying a downward force to the swivel wheel which causes the swivel wheel to be set at an operative position and two of the non-pivoting wheels to be raised relative to an underlying ground surface, and means for setting an angle of the swivel wheel relative to a lengthwise extending centerline of the cart body to cause the cart to rotate about a center of rotation that is determined by the set angle of the swivel wheel.

A wheeled platform has a base, a plurality of wheels, and a power supply. A connector extends from the wheeled platform. A motor assembly has at least one motor mounted on the connector to couple with a conveyance. A controller assembly steers the conveyance. The base includes an upper surface for supporting an operator. The base forms a wheel assembly for holding the wheels. The power supply sends power to the motor assembly through the control assembly to drive the conveyance.

There is provided an ultrasonic imaging device capable of controlling a moving device according to a movement direction of a platform in the front or the rear thereof. An ultrasonic imaging device includes a platform to which an ultrasound probe is connected, a moving device configured to move the platform, and a manipulation unit configured to control the moving device to be in any mode of an aligned movement mode, a free movement mode and a stop mode, wherein the manipulation unit includes a first manipulation unit that is provided in a first direction of the platform and controls operations of the moving device and a second manipulation unit that is provided in a second direction facing the first direction of the platform and controls operations of the moving device.

A handcart is provided that includes a frame, wheels, and a motor that drives the rotation of the wheels. The number of wheels is two. The handcart includes a platform coupled to the frame, including a base and a vertical structure. It allows providing a self-propelled handcart with the two wheels and a variable length chassis that is as simple, safe to use, and inexpensive.

A conveyor system conveys devices for receiving components to be welded together, especially for internal combustion engine exhaust systems, into and out of a welding cell. The conveyor system includes a conveying vehicle (62) with a chassis (64) that can travel on a subfloor via rollers (68). A superstructure (78) is carried vertically adjustably on the chassis (64). At least one device carrier (14) receives components to be welded together in a position intended for the welding together in relation to one another. A positioning/holding formation (94) is provided on the superstructure (78) and a counter-positioning/holding formation (103) that meshes or can be caused mesh with the positioning/holding formation (94) is provided on the device carrier (14) for presetting a conveying position of the device carrier (14) on the superstructure (78).
