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.

Operating room tables have limited height adjustment capability. To adequately treat a patient, surgeons often have to risk back injury and/or stand on rickety piles of prior art step stools, which is unsafe and can compromise sterility. Here, a computer-processor-controlled, motorized, surgical step-platform device is disclosed. The device is configured to have dimensions similar to a step stool. The device is configured to easily slide across a floor to an operating table. Then, often by remote control from a Smartphone, the device can vacuum affix itself into position and automatically raise between 5 to 18 inches above the floor. The device has sophisticated rechargeable battery power management and further accommodates wired, and wireless foot switches to control nearby surgical equipment.

The present disclosure relates to the technical field of mechanical equipment for aerial works, in particular to a small scissor aerial work platform and a traveling chassis thereof. The traveling chassis includes a base and oppositely-arranged left and right steering wheel assemblies. The base is of a concave structure, a scissor-stored groove with an upward opening is formed in the base, a left wheel set accommodating groove and a right wheel set accommodating groove which are used for accommodating the steering wheel assemblies and provided with downward openings are further formed in a front end of the base, and a lower portion of the scissor-stored groove is located between the left wheel set accommodating groove and the right wheel set accommodating groove.

An access deck assembly is provided for an aerial lift vehicle mobile platform. A base member defines an upper surface to support an operator, and has first and second guides to cooperate with the platform. A locking mechanism is supported by the base member and retains the access deck to the platform. A method of connecting an access deck assembly to a mobile platform is provided. The access deck assembly is positioned relative to the platform to be above and spaced apart from the platform floor surface, with the base member of the access deck assembly substantially within a perimeter frame of the platform. An access deck assembly has a guide member connected to a base member and configured to connect the base member to the mobile platform and support the base member directly above and spaced apart from the platform floor surface.

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.
