摘要： A lift device includes a base, a platform that is repositionable relative to the base between a fully raised position and a fully lowered position, a scissor assembly coupling the base to the platform, and a booster. The scissor assembly includes a scissor layer including a first scissor arm pivotally coupled to a second scissor arm, a pulley coupled to the scissor layer, a tensile member wrapped around the pulley, and an actuator configured to vary a working length of the tensile member such that the first scissor arm rotates relative to the second scissor arm to move the platform relative to the base. A booster is positioned to engage a portion of the tensile member and apply an upward force on the scissor assembly when the platform is in the fully lowered position.

摘要： A lift device includes a scissor assembly coupling a base to a platform. The scissor assembly includes a first scissor layer including a first inner arm configured to rotate relative to a first outer arm about a middle axis. The first scissor layer has an end axis center point defined based on the positions of the end axes about which the first inner arm and the first outer arm rotate. The first middle axis is offset from the first end axis center point. The scissor assembly further includes a second scissor layer coupled to the first scissor layer and extending between the first scissor layer and the platform. The second scissor layer includes a second inner arm pivotally coupled to a second outer arm.

摘要： A support apparatus 1 for supporting a user in an elevated working position above a ground surface G comprises a frame 60 for supporting a floor portion 20 of the support apparatus and a plurality of leg members 40a, 40b mounted to the frame 60 for supporting the frame above the ground surface G. Each leg member has a foot portion 42 for engaging the ground surface G. Each leg member is rotatably mounted to the frame for rotation about a rotational axis which is substantially perpendicular to the width and the length of the frame and each leg member extends from the frame in a radial direction of the rotational axis, whereby the foot portion is offset from the rotational axis.

摘要： An adjustable support prop that can be customized to the support requirements of a wide variety of objects to be held in place. The prop includes first, second and third support members which are coupled together in a manner that allows the weight of an object to be supported in order to provide stability to the prop. The length of one of the support members is adjustable so that the height of the prop can be customized to the support requirements of the object to be supported.

摘要： A lightweight, multi-function scaffold includes an adjustable height platform that slidably mounts between two ladder frames and a plurality of outriggers to increase stability. The outriggers attach to the ladder frames of the scaffold and extend beyond an end of the scaffold in the longitudinal direction to increase the maximum base width. Increasing the maximum base width increases stability in the longitudinal dimension and reduces the risk of tipping the scaffold end over end when a user climbs the ladder frame to access the platform.

摘要： A lift apparatus includes a ladder assembly having a first ladder end portion and a second ladder end portion extending upwardly from a base framework, each end portion having a pair of upstanding support legs and a plurality of rungs. The lift apparatus includes a platform that is slidably coupled to respective support legs of respective ladder end portions, the platform having a floor surface capable of supporting a person. The lift apparatus include a motorized pulley system operable for raising and lowering the platform relative to the ladder end portions via a controller accessible to the worker while standing on the platform.

摘要： The elevating lift with a stabilized movable base includes a base with extendable legs that provide minimum to maximum adjustable stability during use and transport. A lift system is mounted on the base, and a platform assembly is mounted on top of the lift system for selective raising or lowering. Each extendable leg supports a caster, rendering the base movable, and selective extension and retraction of the legs adjusts the stability of the lift. The plurality of legs can be further driven to simultaneously rotate about the vertical axis to steer the lift. The stabilized movable base is further alternatively used in combination with a stool, providing minimum to maximum stability during use and transport of seating, and multiple elevating lifts may be used to support linked platform assemblies in various configurations.
