Patent number: 6634172Abstract: A method and apparatus for operating a load lifting device to move a load and hold the load steady is disclosed. In the conventional arts, a lifted or lowered suspended load had a tendency to move from its desired position, as hydraulic fluid in the lifting system cooled, e.g. a stick slip condition. The present invention monitors a fluid pressure in the lifting system and compensates the fluid pressure to accommodate any pressure drop due to fluid cooling. Thereby, the load can be effectively held steady at a desired position, and the stick slip condition can be avoided.Type: GrantFiled: February 26, 2002Date of Patent: October 21, 2003Assignee: Grove U.S. LLCInventors: Stephen J. Schoonmaker, Jeffrey L. Addleman

Patent number: 4718814Abstract: A mechanism for use on a boom-type vehicle includes load lifting forks carried by a low profile twist-resistant carriage which is one link in a low profile parallelogram linkage attached to a fly section of the boom and maintained level in all positions of the boom by a slave cylinder connected between the boom and a slave link which constitutes a member of the parallelogram linkage. The mechanism can be adjusted to many positions while automatically maintaining the relative position of the forks with respect to the vehicle frame for any boom angle. The mechanism can be adjusted to provide a long reach over or under obstructions in order to remove or place a load. It may also engage loads below ground level. Load pick-up or placement can be performed in confined areas which are unreachable by conventional forklift trucks.Type: GrantFiled: December 11, 1986Date of Patent: January 12, 1988Assignee: Kidde, Inc.Inventor: Jeffrey L.

Patent number: 4454780Abstract: The mechanism, designed especially for use in an earth compacting drum, comprises a pair of concentrically-arranged, eccentrically-weighted elements, which are rotated in unison by means of a hydraulic motor. The mechanism is housed within an earth compacting drum, and the one eccentrically-weighted element is translatable, axially, and disengageable from a splined coupling, in order that it may be indexed to different rotary positions relative to the other eccentrically-weighted element. In this manner, vibratory amplitudes may be increased or decreased.Type: GrantFiled: July 6, 1981Date of Patent: June 19, 1984Assignee: Ingersoll-Rand CompanyInventors: Robert F. Goehler, Jeffrey L.
