Patent number: 9422142Abstract: The subject invention includes a lift system including a first scissor-type lift assembly and a second scissor-type lift assembly spaced from the first scissor-type lift assembly. The first scissor-type lift assembly includes a first base and a first platform coupled to the first base for movement between elevated and lowered states. The first scissor-type lift assembly includes a first motor operatively mounted to the first base. The second scissor-type lift assembly includes a second base and a second platform coupled to the second base for movement between elevated and lowered states. The second scissor-type lift assembly includes a second motor operatively mounted to the second base. The first and second motors move the first and second platforms between the elevated and lowered states.

Patent number: 8733508Abstract: A lift assembly includes a base and a platform at a relatively greater distance from the base in an extended state than in a contracted state. The lift assembly includes a pair of scissor arms with each arm having opposed first and second ends, and pivotably connected to each other about a central axis. The lift assembly includes a drive screw mechanism including a shaft defining a longitudinal axis, and further includes a drive motor, a block, and a collar. The lift assembly further includes first and second pairs of links. Each link has opposed first and second ends and an edge facing away from the central axis and defining a recess in the link. The collar and block are spaced from the central axis and indirectly coupled to the pair of scissor arms through a pair of links.Type: GrantFiled: April 2, 2010Date of Patent: May 27, 2014Assignee: Herkules Equipment CorporationInventor: Todd J.

Patent number: 8714524Abstract: A belt-driven transportation system including a first set of pulleys rotatably attached to a first member and a second set of pulleys rotatably attached to a second member. The first and second members have relative movement to each other. The system further includes a unitary belt that is guided through a path defined by the first and second sets of pulleys. A plurality of flange members maintain a proper positioning of the belt on the pulleys.Type: GrantFiled: October 26, 2010Date of Patent: May 6, 2014Assignee: Herkules Equipment CorporationInventor: Todd J.

Patent number: 8662477Abstract: A belt-driven transportation system including a first set of pulleys rotatably attached to a first member and a second set of pulleys rotatably attached to a second member. The first and second members have relative movement to each other. The system further includes a unitary belt that is guided through a path defined by the first and second sets of pulleys with the path substantially lying in a stationary plane, and a plurality of retention rollers. A retention roller is disposed adjacent each pulley, with the belt extending about the pulley and between the pulley and the retention roller. The positioning of the belt substantially on the path is maintained by the plurality of retention rollers, and the first and second members are moved relative to each other with changes in the length of the path.Type: GrantFiled: December 16, 2009Date of Patent: March 4, 2014Assignee: Herkules Equipment CorporationInventor: Todd J.

Patent number: 8052120Abstract: A vertical lift mechanism (100, 100a, 100b) including: a lift support assembly (102) comprising an upper frame member (104), a lower frame member (106), the upper frame member is movable between a lowered position and a lifted position. The lift support assembly additionally includes a support mechanism (150) that holds and maintains the alignment between the upper frame member and a lower frame member as well as a powering unit to cause movement of the upper frame.Type: GrantFiled: May 5, 2009Date of Patent: November 8, 2011Assignee: Herkules Equipment CorporationInventor: Todd J Bacon

Publication number: 20110240409Abstract: A scissors-type lift assembly including a base and a platform, the lift assembly having extended and contracted states, with the platform at a relatively greater distance from the base in the extended state than in the contracted state. The lift assembly includes a pair of scissor arms each having opposed first and second ends, and pivotably connected to each other about a central axis located between their respective first and second ends, the first end of each scissor arm coupled to the base, the second end of each the scissor arm coupled to the platform. The lift assembly also has a drive screw mechanism including a shaft, a drive motor rotatably coupled to the shaft, a block threadedly engaged with the shaft and having longitudinal movement relative to the shaft, and a collar relative to which the shaft is rotatable and longitudinally fixed relative to the shaft.Type: ApplicationFiled: April 2, 2010Publication date: October 6, 2011Applicant: HERKULES EQUIPMENT CORPORATIONInventor: Todd J.

Patent number: 7070167Abstract: A lifting apparatus comprising: one of a mobile/or and stationary base; a lift platform having a geometric first center, the lift platform movable relative to the base from a lowered position to an upper position; a linkage or linkage mechanism interconnecting the base and the lift platform for guiding the base and the lift platform to stay in a generally mutually parallel relationship as the lift platform moves relative to the base; the base, lift platform and linkage configured so that when the lift platform in its lowered position the first center intersects the base at a first point and with the lift platform in its upper position the first center intersects the base at a longitudinally off-set second point; and a fluid (fluid/pneumatic) control spring operatively mounted between the lift platform and the base, for controllably lifting and lowering the lift platform.Type: GrantFiled: January 10, 2004Date of Patent: July 4, 2006Assignee: Herkules Equipment CorporationInventors: Todd J. Bacon, Richard A. Robb
