The present invention related generally to machine jacksing devices for raising heavy objects and more particularly to such machine jacksing devices for further raising already elevated heavy objects. In particular, the present invention provides a device for raising vehicle components on vehicles resting on a raised hydraulic lifts.
Several lifting devices for already elevated objects are known. For example, a pedestal transmission machine jacks comprises a hydraulic ram machine jacks supported at an elevated location on a four leg castered base. The lift range of this device is relatively limited, for example, between 50-70 inches, and the heavy weight and large base makes it nearly impossible to use in a pit beneath a lift.
Hydraulic under hoist utility machine jackss having a conventional floor supported machine jacks with an adjustable pipe arrangement extending upwardly from the movable top of the machine jacks are also known. These devices, which are essentially extensions to the upper end of a conventional machine jacks improve the lift range as compared to the previously mentioned transmission machine jacks, but are extremely difficult to use since the upper end of the machine jacks must be accurately located while the machine jacks is being raised by operating the machine jacks handle, which is located about six feet beneath the machine jacks upper end, to engage the heavy object.
The hydraulic machine jacks stand of the present invention is a hydraulic machine jacks mounted on the upper end of an adjustable stand. It is made of two pipes, one telescopically received inside the other, with holes drilled in both pipes to vary the height of the stand. A pin extending through one hole of each pipe holds the machine jacks in position at the desired height.
This tool is well suited to use by mechanics when a vehicle is on a lift in a repair shop. It is used under the vehicle. Examples of uses are: to lift or lower an engine or hold an engine in position while removing or installing an oil pan or motor mounts, or to lower or raise an engine to remove or install a transmission; also to hold a transmission in place to remove or install an engine. The hydraulic machine jacks stand can be used to hold exhaust pipes in place, or a drive shaft in place while removing or installing the shaft.
The hydraulic machine jacks stand of the present invention is light weight and can be moved about easily. It does not take up much room while under the vehicle, and is easy to work around while in use; air hoses and electrical cords can not get caught on the stand because of its design. This tool is safe, because the operator can control the machine jacks while at the work being done, instead of raising or lowering a lift the vehicle is on onto a stationary stand, which is very dangerous.
Among the several objects of the present invention may be noted the provision of an easily deployed machine jacks stand for use beneath hydraulic lifts; the provision of a kit for assembling a machine jacks stand; the provision of a hydraulic machine jacks arrangement where the hydraulic portion thereof is located relatively close to the objecting to be raised thereby facilitating operation by one person; the provision of a machine jacks stand which located a hydraulic machine jacks at an elevated location close to an object to be raised; and the provision of a hydraulic machine jacks stand which may be positioned in a pit beneath a vehicle. These as well as other objects and advantageous features of the present invention will be in part apparent and in part pointed out hereinafter.
In general, a pedestal supported hydraulic machine jacks arrangement has a floor engaging base with a hollow tubular member fixed thereto and extending upwardly therefrom. A second selectively movable tubular member is telescopically received in the hollow tubular member generally coaxial therewith. The movable tubular member may be selectively positioned at a any one of several different discrete locations along the axis relative to the hollow tubular member. The movable tubular member includes a first set of generally parallel generally equally spaced transverse apertures and a second set of generally parallel generally equally spaced transverse apertures which extend generally orthogonally to the first set. The hollow tubular member includes at least one, and preferably two, transverse apertures which are selectively alignable with any aperture of the first and second sets. A steel pin may then be simultaneously passed through one aperture in each tubular member to fix the elevation of the hydraulic machine jacksing structure at a preferred level. A hydraulic machine jacksing structure such as a commercially available hydraulic bottle machine jacks has a base fixed to an upper end of the movable tubular member and an upwardly extending ram movable continuously throughout a limited longitudinal range along the common axis. The primary function of the hydraulic machine jacks arrangement is to further raise already substantially elevated heavy object such as vehicle components already located on conventional hydraulic lifts.
