Abstract: The present invention is a powered lift platform including a platform, at least one guide rail section in operative contact with the platform, each of the at least one guide rail sections comprising at least one guide rail and in which a first end of each of the guide rail sections is configured to removably attach to a second end of a second guide rail section. The invention also includes a lift mechanism supported by the platform, a lift guide in operative contact with the lift mechanism and attached to the upper portion of the upper guide rail, a power supply to operate the lift mechanism. In a preferred embodiment, at least one wheel is operatively attached to the powered lift platform. Also presented is a method for securing the powered lift platform to a columnar-like support. Also presented is an extendable standoff.

Abstract: A skeletal frame, configured in cross-section size to the lateral dimensions of an expanded collapsible bag and including bottom frame members for providing vertical support to the collapsible bag, provides structural support for the collapsible bag during fill thereof. Handles attached to the frame translate a lifting force applied thereto through the frame to the bottom and sides of the collapsible bag, regardless of the degree of fill of the collapsible bag.
