A motorized turntable assembly configured for rotation of vehicles, which may be assembled on site and installed in a driveway or garage. The turntable assembly includes an annular platform that is assembled from a number of wedge-shaped sections and has an outer disk partition, an inner disk partition, and a central opening defining a cylindrical axle therebetween; wherein the annular platform is mounted on the cylindrical axle for rotational support and elevation above a foundation. There is an inner rail and outer rail, and a plurality of weight bearing and non-weight bearing wheels disposed around the central opening. A motor assembly consisting of a motor connected by a single, continuous belt is wrapped around the outer circumference of annular platform, and a spring tensioned pivot mechanism keeps the belt in contact with the annular platform.

Use of cars is part of the modern life. However, many times handling these units are difficult, time and energy consuming. One of such conditions is making a U-turn in a narrow driveway or the end of a narrow valley or street. This invention introduces a method and means which allows a wheeled unit to rotate and make a U-turn in a small place easily. The applicant believes this will make the life of many humans easier.

The present disclosure provides a vehicle positioning device for vehicle vision calibration, a positioning adjustment method, and a positioning adjustment system. The vehicle positioning device includes a base, a chassis, a translation mechanism and a rotation mechanism. A to-be-calibrated vehicle is placed onto the chassis, and the chassis is provided with a stopper. The translation mechanism is arranged between the chassis and the base, and configured to drive the chassis to move in an X-axis direction in a three-dimensional coordinate system relative to the base in accordance with a translation control instruction. The rotation mechanism is arranged between the chassis and the base, and configured to drive the chassis to rotate about a Z-axis in the three-dimensional coordinate system relative to the base in accordance with a rotation control instruction.

A carrier body of a lift carrier includes: a pair of wheel support mechanisms that supports a first wheel of a vehicle to be transported; a frame-shaped structure connected to the wheel support mechanisms; and one or more lifting units that lift or lower the pair of wheel support mechanisms. The frame-shaped structure includes a frame portion and an upper plate and is open on a lower side of the carrier body. Each of the lifting units includes a wheel support and an air spring. The air spring is interposed between the wheel support and an upper plate. As the air spring expands, the wheel support is rotated about one end of the wheel support rotatably supported by the frame portion, and is deployed out of the frame-shaped structure.

A rotary milking platform 1 has a deck 2, a circular upper beam 4 connected to and supporting the deck, a circular lower beam 6 and a series of carriages 5 connected end to end to form a ring between the beams. The platform is formed such that the upper beam 4 is arranged to rest and rotate on the ring of carriages 5 to rotate the deck 2. Each carriage has at least one carriage roller 10, and each roller 10 arranged to rotate on the lower beam 4. Each roller 10 also has a retention flange 11 at only one side. The flanges 11 of some of the rollers 10 are at or adjacent an inner side of the ring, and the flanges 11 of others of the rollers are at or adjacent an outer side of the ring. The rollers 10 of the ring are arranged such that at least one roller is oriented with its flange 11 on an opposite side to another of the flanged rollers immediately adjacent to it. The flanges prevent the carriages from moving off the lower beam 4 when the platform 1 is in use. Further, at least some of the carriages can be disconnected from the ring and swung laterally to be moved free of the beams 4, 6 for maintenance, repair or replacement.
