Lifting and leveling apparatus and method
First Claim
1. For a self-propelled vehicle used to transport and position a burial vault or monument load, a method for maintaining the burial vault or monument load in balance during transport over varying terrain, the method comprising the steps of:
- providing a deck associated with the self-propelled vehicle for carrying the burial vault or monument load, the deck comprising a frame to support the load and a load platform to receive the load; and
using a cable driven trolley to move the load platform up or down on either or both sides to continuously maintain the load in a balanced orientation responsive to varying terrain traversed by the self-propelled vehicle.

Abstract
A lifting and leveling apparatus and method improves the handling and transportation of a burial vault and monument. A lift mechanism is attached by pivot pins to both the transport (lower) portion of the structure and the vault handling (upper) portion of the structure, thereby allowing the vault or monument to be lifted on a straight vertical axis or to be tilted side to side to balance the load, while the entire load and equipment remains on the transport tires. The deck, carrying the vault or monument and lid, and comprising the frame structure for positioning the vault or monument and the lift mechanism, can lift and pivot independent of the transport vehicle to adjust the center of gravity of the deck and maintain the load in a level orientation, while in the transport mode and while stationary. The lift/tilt mechanism is located so as to adjust the center of gravity of the deck independent of the transport vehicle.
