Patent number: 8985275Abstract: A lift safety system that prevents the lifting of a support platform from a support base until all of the support legs for the support base are supporting a minimum amount of weight to ensure stability of the lift. The support base includes a plurality of legs that extend outwardly with each of the legs having an adjustment member with a pad that engages a ground surface. As the adjustment member is adjusted downwardly with respect to the leg, a first engaging member connected to the adjustment member is elevated upwardly to engage a second engaging member thereby releasing a corresponding finger member attached to the support platform from the support base. Once all of the legs are supporting a minimum amount of weight, all of the finger members are released from the support base thereby allowing elevation of the support platform.Type: GrantFiled: October 17, 2014Date of Patent: March 24, 2015Assignee: Reechcraft, Inc.Inventors: Jason M. Solhjem, Shane L. Nickel

Patent number: 8973709Abstract: A lift includes a mast and a brake module. The mast is for disposing on a working surface and has at least one track. The brake module is connected to a lift module mounted on the mast and includes at least one friction member and at least one forcing member. The friction member has a pressing portion and an axle oppositely arranged. The pressing portion is substantially shaped to engage the track. The forcing member is rotatably disposed on the axle for pivoting axially between a first position and a second position. At the first position, the pressing portion can be moved along the track and stopped by the lift module. At the second position, the forcing member displaces the friction member to force the pressing portion tightly against the track. Thus, the brake module is held in position relative to the mast.Type: GrantFiled: August 16, 2012Date of Patent: March 10, 2015Assignee: Syncmold Enterprise Corp.Inventors: Der-Wei Lu, Chung-Cheng Hu

Patent number: 8931994Abstract: The present invention is a lift accessory for aerial lifts and related machines. The lift accessory includes sets of retractable supports for materials around the perimeter of an aerial lift platform. In a preferred embodiment, two accessories would be installed on opposite ends of the lift platform. Typically, the accessory is based upon a section of steel tubing. The inside end may be pivotally attached via a bolt or other appropriate attachment means to a railing on a work platform of the lift.Type: GrantFiled: August 27, 2012Date of Patent: January 13, 2015Inventor: Conor P. Creaney

Publication number: 20150008072Abstract: A variable height support with a platform and a base supporting the platform and reconfigurable to selectively change a height of a support surface on the platform relative to a subjacent surface. A control assembly is operable to selectively: a) maintain the support surface at a selected height; and b) release the platform to allow the base to be reconfigured to change the height of the support surface. The control assembly has a ratchet subassembly that, with the control assembly in a first state, allows the base to be reconfigured by exerting a continuous upward force upon the platform that causes the platform to elevate and be blocked within a range at a plurality of different vertical locations against downward movement. The control assembly further has an actuator that is repositionable to change the control assembly into a second state wherein the platform can be lowered over the range.Type: ApplicationFiled: July 2, 2013Publication date: January 8, 2015Inventors: Howard T. Knox, Edward K. Saunders

Patent number: 8905190Abstract: An admission system, particularly for containers, with a raiseable platform. The system includes towers of carryable profiles with at least one longitudinal recess adapted for interference by at least one steering element. Each profile has an end portion adapted for interference with other carryable profiles. The profiles have the same cross-section and can be joined. Interlocking elements are placed between the profiles for joining. A toothed rack extends along the longitudinal direction of the profiles. A guiding element for connection with a working platform is connected to the at least one steering element and includes a pinion meshing with the toothed rack and a transmission for driving the pinion. Support elements are provided for attaching the profiles to a structure or other profiles. The invention also includes a method for assembly of such a system, a profile, a guiding element and support elements for such a system.Type: GrantFiled: May 26, 2009Date of Patent: December 9, 2014Assignee: Noracon ASInventors: Ole Petter Stromland, Willy Arnold Fagerland

Publication number: 20140332317Abstract: A mast lift includes a base and a telescoping mast coupled with the base and extending upward from the base. The telescoping mast has a support section fixed to the base and a movable section movably connected and displaceable relative to the support section between a retracted position and an extended position. A top cap is secured to the movable section, and a platform is supported by the top cap and the movable section. A gas strut acts between the support section and the movable section and biases the movable section toward the extended position. A threaded driving rod is connected between the top cap and the base and extends through a fixed nut assembly.Type: ApplicationFiled: July 23, 2014Publication date: November 13, 2014Inventors: Geoffrey George Campbell, Jason James Watson, Mark Nathan Spaile
