ABSTRACT:
BACKGROUND
This invention relates to engine lifting and positioning assemblies.
To repair or service motor vehicles, it is often necessary to remove the engine from the engine compartment of the vehicle and to secure the removed engine so that the portion of the engine which must be repaired or rebuilt may be exposed to a mechanic. After the required work has been completed, it is then necessary to place the engine back into the vehicle, or replace it with a new engine. This can be dangerous for the mechanic due to the weight and physical imbalance characteristics of the engine.
SUMMARY
In an aspect, the invention features a base structure and a main column vertically attached to the base structure, the main column having a mounting plate affixed above the base structure, the mounting plate adapted to attach to an engine. A rod is connected to the plate and positioned through the main column, the rod having a terminal handle opposite the plate to provide rotational movement to the plate. A boom is horizontally and pivotally attached to a top of the center beam. A trolley assembly is attached to the boom, a position of the trolley assembly along the boom controlled by a cable joined to a motor on the boom. A piston and cylinder assembly is fixedly attached between the main column and boom.
Embodiments include the base structure having a base support member attached to the main column and positioned between a pair of spaced apart legs, a rear support beam joining the pair of spaced apart legs, and a pair of diverging stabilizing braces positioned between the rear support beam and the top of the center beam.
One or more of the following features may also be included: the spaced apart wheel assemblies of the rear support beam and spaced apart legs may include wheel assemblies; these wheel assemblies may be locking. Control of the pulley, motor, and piston and cylinder assembly may be combined into a single remote device.
Embodiments of the invention may have one or more of the following advantages.
An engine may be removed from or re-positioned in a vehicle without the need to move the entire lift. The engine may be raised and then slide back away from the vehicle by the action of the trolley. Once removed, the engine may be positioned and affixed safely to the plate before the lift is withdrawn from the vehicle.
The control of the entire lift can be done remotely. Further, two lifts facing each other make it efficient and easy to transfer a single engine from one lift to another.
The details of one or more embodiments of the invention are set forth in the accompanying drawings and the description below. Other features, objects, and advantages of the invention will be apparent from the description and drawings, and from the claims.
