BACKGROUND OF THE INVENTION
[0003] 1. Field of the Invention
[0004] The present invention relates generally to elevating devices
and more specifically it relates to a hydraulic boom cart system
for elevating and positioning material within confined spaces.
[0005] 2. Description of the Related Art
[0006] Material elevating devices such as forklifts and tractors
have been in use for years. Conventional material elevating devices
require a motor to provide power to the material elevating devices.
In addition, conventional material elevating devices are relatively
large in size and difficult to operated in small and confined
areas.
[0007] Examples of patented devices which may be related to the
