Deployable Hybrid Mobile Elevating Access Platform

The invention is a mobile maintenance stand that combines the function of an adjustable stairway and hydraulic scissor lift that independently elevates and descends an access work platform to support maintenance tasks on commercial and military aircraft. The elevating access work platform has an extended reach of 144' and is initiated by a secondary hydraulic scissor lift that promotes upward extension beyond the parameters of the adjustable stairway reach, to provide further maintenance access. The additional extension range of the access work platform with a hydraulic scissor device, provides vertical movement to the work deck at all check levels. Further, this invention is self-contained that collapses to a compact dimension and be transported on an air cargo pallet. Thus, the invention's mechanical scheme of the scissor lift to extend access work platform beyond the adjustable stairway is novel and, is unlike any existing articulating stairway and, or scissor embodiments.

Attachment to stabilize and expand the use of hollow rung ladders

A pair of attachments for use with ladders constructed with hollow rungs to stabilize the ladder and to protect the gutter. These attachments when used with ladders also provide for a scaffold plank. The attachments when used with a ladder on a pitched roof allows the ladder to be used to access that roofs peak. Previously the ladder would rest on the rain gutter when the user was to access the roof of a building. Previously a work platform had to be built from wood or metal resulting in time consuming construction. Previously when accessing the roof peak of a building a means of providing a positive foothold had to be constructed from rope and ladder or from wood. The present invention provides steel flat bars bent to fit the rung spacing of the ladder with a steel tube welded at each end sized to fit snuggly into the opening of any two consecutive rungs in that ladder. The ladder can now be used to access the roof of a building without resting on the gutter. The ladder can be used as part of a scaffold and to provide a positive foothold when on a pitched roof.
