Publication number: 20210009393Abstract: A load feedback assembly includes a load receiving portion moveably secured within a main body, a sensor device selectively engageable by the load receiving portion, and a biasing device disposed between the load receiving portion and the sensor device. The biasing device has a biasing force that is configured to urge the load receiving portion away from the sensor device, and the biasing force is overcome when a load on the load receiving portion exceeds a predetermined weight threshold.Type: ApplicationFiled: July 12, 2019Publication date: January 14, 2021Applicant: MVP (H.K.)

Patent number: 9376132Abstract: A car dolly comprises a frame having a supporting portion and a tire receiving portion. The supporting portion has a plurality of wheel acceptance areas. The tire receiving portion comprises a pair of angled inner walls and a pair of outer walls. The dolly has a pair of rotatable arms and a reversible saddle. In an extended configuration, each rotatable arm extends above the frame at an angle. In a retracted configuration, each rotatable arm extends generally horizontally underneath the frame.Type: GrantFiled: June 26, 2015Date of Patent: June 28, 2016Assignee: MVP (H.K.) INDUSTRIES LIMITEDInventor: Derek Ryan Cudney

Patent number: 6899319Abstract: A jack having a detachable rear-end handle comprises a wheeled jack and a hand-held ring. Two sidewalls of the jack are each provided with a pair of blocking pieces respectively mounted on an upper location and a lower location about a screw nut of a rear shaft. The hand-held ring can be coupled to screw nuts of a rear shaft. The blocking pieces further restrict the rotation of the hand-held ring. The connection of the hand-held ring at the rear end of the jack not only facilitates carrying the jack but also controlling the movements of the jack to a proper lift point.Type: GrantFiled: August 19, 2003Date of Patent: May 31, 2005Assignee: MVP (H.K.) Industries LimitedInventor: Victor Hung

Patent number: 6247307Abstract: A hydraulic raising apparatus with automatic regulated speeds can automatically adapt its raising speeds for various load conditions. It mainly comprises additional hydraulic circuits, check valves and adjustable relief valves arranged between the piston rod side chamber and the rodless side chamber of hydraulic cylinders and pumps. The arrangement enables hydraulic cylinders and pumps to change their working modes in a hydraulic circuit, depending on loaded conditions, from a piston type to a spool type and vice versa. Hence the hydraulic apparatus can adjust its raising speeds in agreement with loads. When the apparatus bears a light load, it will quickly carry the load to position. On the other hand, when the load is heavy the apparatus will move it at a slower speed and thus need just reduced input energy. Therefore, the apparatus according to the invention can enhance efficiency to the greatest extent.Type: GrantFiled: September 13, 1999Date of Patent: June 19, 2001Assignee: MVP (H. K.)

Patent number: 6199379Abstract: An oil circuit of a jack for rising an object to a preset position rapidly, wherein the oil inlet circuit of a hydraulic loop system is improved. An oil channel is installed between the inner oil chamber of the piston rod and the sequential valve. A check valve is installed between the oil channel and the sequential valve. An oil channel is installed between the sequential valve and the check valve for being connected to the inner oil chamber of the piston rod. By changing the positions of the check valve and the oil channel. When in the working conditions of dump load or light load, the sequential valve is closed, thus, the hydraulic oil may enter into the inner oil chamber of the piston rod from the pumping oil chamber through the check valve so that the piston rod will rise rapidly to a still condition. In the still condition, since the check valve closes the oil channel, the sequential valve will open automatically so that the inner oil chamber of the piston rod is communicated to the inner oil reservoir.Type: GrantFiled: October 8, 1999Date of Patent: March 13, 2001Assignee: MVP (H.K.)

Patent number: 5937647Abstract: A hydraulic circuit system for one-touch jack and its structure has an inlet circuit, a return circuit and an overload protection circuit with a hydraulic cylinder, a piston rod, a sequence valve, a safety valve and a relief valve, in which the inlet circuit extends from an outer reservoir of a hydraulic cylinder via a check valve to connect to an oil chamber of a manual pump. The oil chamber of the pump is connected to an oil guide tube via another check valve, the oil guide tube is inserted into an inner oil chamber formed in a piston rod to form a closed circuit. The oil chamber of the pump is connected to an inner chamber of the hydraulic cylinder via a sequence valve and the inner chamber is connected to the outer reservoir via a check valve.Type: GrantFiled: February 13, 1998Date of Patent: August 17, 1999Assignee: MVP ( H.K.)
