A device for use in lifting, transporting and installing sheet material has a base, wheels on which the base is supported, a mast that extends upwardly from the base, a carriage that is in engagement with the mast, a supporting head that is mounted to the carriage, and a lifting mechanism to provide support to the carriage in the longitudinal direction of the mast. The wheels include rear wheels that are connected to the rear of the base in a manner that permits steering of the device during movement across a surface, and a front wheel set that is connected to the front of the base. The front wheel set includes a wheel to each side of the device, and the wheels of the front wheel set are rotatable about a common axis. The connection of the mast to the base is such that the mast is rotatable relative to the base about a rotational axis. The device further has an actuator that is operable to change the angular position of the mast relative to the base. The supporting head is configured to support sheet material above the surface.

A transportation device and automatic tilt stabilizer are disclosed herein. The transportation device has a structure with wheels joined by a shaft to a platform or chassis configured to support a basket, a mat, a seat and/or a tray. The automatic tilt stabilizer is configured to automatically stabilize the inclination of the platform or chassis, and includes a tilt sensor configured to detect an inclination of the platform or chassis, and a motor activated by a microcontroller, configured to correct the inclination of the platform or chassis, so that the platform or chassis returns to a predefined inclination.

An assistive device for heavy tool operation includes a rectangular frame and four legs extending from the corners of the frame. A tool base can extend through a slot in the frame. The tool base is configured to support a mechanical support arm and tool. A height and horizontal position of the tool base relative to the frame is adjustable. Each leg is connected to a wheel to allow the assistive device to travel with a user. The assistive device can support a majority, if not all, of the weight of an attached heavy tool and mechanical support arm, while allowing the user to operate the tool and adjust its position with minimal applied force.

A device for lifting and transporting sheet material includes a base portion; wheels on which the base portion is supported; a mast that extends upwardly from the base portion; a boom that extends from a first end outwardly from the mast to a second end; a supporting head that is configured to support sheet material; and a pivot coupling at the second end of the boom. The pivot coupling is arranged to couple the supporting head to the boom, and enable the supporting head to be rotated about a pivot axis between a first position in which sheet material supported by the supporting head is in a generally transverse orientation relative to the boom, and a second position in which the angle between sheet material supported by the supporting head and the boom is reduced.

A weight-bearing device includes a single wheel, a frame attached to the wheel, and an electric motor attached to the frame. The electric motor is configured to rotate a first gear, connected to a second gear with a chain. The second gear is connected to the wheel. The second gear and the first gear may have a gear ratio of greater than 8:1.

A wheelbarrow for carrying materials is described herein, and may include a main frame having first and second spaced-apart elongate longitudinal arms and a support structure configured to engage the ground when the wheelbarrow is in a stationary position, a load carrying container for receiving a load therein, the load carrying container being mounted to and supported by the main frame and configured for supporting a load, an axle mounted to the main frame and below the container, and a ground engaging wheel rotatably mounted on the axle for moving the wheelbarrow in a mobile position. A hollow interior of the load carrying container may have an upper region and a lower region, the upper region located above the ground engaging wheel and extending along a substantial portion of a width of the container.

A bag configured for attachment to a stroller, a stroller in combination with a first and a second bag, and a method of stabilizing a stroller are provided. A stroller including a front support bar, a rear support bar, and a rear axle is used for transportation. A bag configured for attachment to the stroller has a front engagement member, a rear engagement member, a body coupled between and supported by the front and rear engagement members, the body includes at least one pocket arranged inside the body, and a receptacle in the at least one pocket. A weight is received by the receptacle, and when the bag is attached to the stroller, the weight applies a rotational moment at the front support bar of the stroller to resist rotation of the stroller about the rear axle.

A device for lifting and transporting sheet material includes a base portion; wheels on which the base portion is supported; a mast that extends upwardly from the base portion; a boom that extends from a first end outwardly from the mast to a second end; a supporting head that is configured to support sheet material; and a pivot coupling at the second end of the boom. The pivot coupling is arranged to couple the supporting head to the boom, and enable the supporting head to be rotated about a pivot axis between a first position in which sheet material supported by the supporting head is in a generally transverse orientation relative to the boom, and a second position in which the angle between sheet material supported by the supporting head and the boom is reduced.

A load moving apparatus including: a ground engaging device configured for rotation about a substantially horizontal axis; a drive member for driving the at least one ground engaging device; a transmission member operably connected to the drive member and the ground engaging device for transmitting drive from the drive member to the ground engaging device; a chassis member which extends along an axis A for supporting the ground engaging device and the drive member, said chassis member including first and second surfaces which define outermost surfaces of the chassis member and which are spaced a first radial distance from the axis A; wherein the drive member extends a second radial distance from the axis A; wherein the second radial distance is greater than the first radial distance.

Provided is a technique including: a main dolly that includes a cargo platform, three or more wheels supporting the cargo platform, and a handle connected to the cargo platform; and a sub dolly that is configured to be movable between a position on the cargo platform of the main dolly and a position outside the cargo platform, wherein the sub dolly includes a front wheel and a rear wheel enabling the sub dolly to move at least in a forward and backward direction, a holder configured to hold an object so that its center of gravity ahead of the front wheel, and a counterweight detachably provided behind the front wheel, and the main dolly is configured to be capable of carrying and conveying the sub dolly in a state of holding the object.
