Publication number: 20030221914Abstract: A portable lift system for transporting and installing electronic systems within a rack system having a lockable rolling support structure including an upright mast, a base and a telescoping support carriage or shelf. The base has first and second telescoping support members which are integrally formed with lockable wheel castors for multi-directional rolling contact with a variety of rolling contact surfaces. The telescopic support members are stabilized by an integrally attached coupler for enabling simultaneous rolling and telescopic motion of the base in a direction perpendicular with respect to a base portion of the mast. The base also includes a lifting assembly which has a carriage connector, at least one motor, a motor support member and a line dispenser.Type: ApplicationFiled: May 28, 2003Publication date: December 4, 2003Inventors: Paul L. Smith, Michael P. Smith

Patent number: 6595329Abstract: A forklift truck includes two driven front wheels, a lifting device, and at least one elevatable component. A flexible hydraulic line is wound up on a drum of the forklift truck. The hydraulic line connects the elevatable component with a non-elevatable component of the forklift truck. The drum is preferably located at least partly between the front wheels of the forklift truck. The front wheels are each driven by respective wheel motors.Type: GrantFiled: February 23, 2000Date of Patent: July 22, 2003Assignee: Linde AktiengesellschaftInventor: Bernhard Gotz

Patent number: 5931262Abstract: A cargo delivery vehicle is described having storage for multiple tiers, or levels, of cargo. The delivery vehicle includes two or more interior elevating platforms, at least one on either side of a center structural wall running parallel to the side walls. Substantially continuous side access doors provide total exterior access to the lowermost tier of cargo. Cargo stored at the upper tier may be positioned by an elevating means at the level of the lower tier for either rear loading or side retrieval purposes. The center structural wall supports a transverse roof truss system that carries suspended outboard loads inward to the center wall. This non-traditional framing system greatly reduces the structural requirements of the side walls and floor, thereby permitting largely open framing for multiple side access ports as well as a minimized floor thickness to permit easier access from the pavement.Type: GrantFiled: January 16, 1996Date of Patent: August 3, 1999Inventors: Robert J. Greenlaw, Todd M. Greenlaw

Patent number: 5871069Abstract: A power option is provided for a manually-operated material lift that employs a telescoping mast system which is extended or retracted by a winch. In one embodiment a reversible electric motor is connected to the winch via two-way reduction gearing that remains in the drive train during manual operation and requires no clutches or disconnect means. In a second embodiment a crankshaft that operates the winch is provided with slide couplings that either engage the manual operating handles or release the handles and engage the motorized drive. The power option is initiated by selecting the position of a reversing switch that controls the motor, and closing an on/off switch which energizes the motor for rotation in the selected direction. When the on/off switch is open, the lift may be manually operated in the conventional manner.Type: GrantFiled: January 29, 1998Date of Patent: February 16, 1999Inventor: Richard A. Carmitchel

Patent number: 5433292Abstract: An improved stacker assembly includes a base assembly and a hollow mast which extends upwardly from the base assembly. A cap assembly is disposed on the upper end portion of the hollow mast. A carriage is movable up and down along the mast to raise and lower a load. The base assembly includes an upwardly extending mast support assembly which is telescopically received in the lower end portion of the hollow mast. The mast support assembly includes a gripper assembly which is operable to grip the inside of the lower end portion of the hollow mast. The cap assembly includes a downwardly extending cap support which is telescopically received in an upper end portion of the hollow mast and is expandable to grip the inside of the hollow mast. In the event of a loss of tension in a support cable for the carriage, a brake assembly on the carriage grips elongated brake bars which are separate from the mast to support the carriage.Type: GrantFiled: August 26, 1993Date of Patent: July 18, 1995Assignee: HK Systems, Inc.Inventors: Ralph B. Haymore, Mark I. Johnson
