Abstract: This invention details a portable Vertical Platform Lift. This Portable Vertical Platform Lift (PVPL) is specifically designed to be transported and set up by a single individual and be used by a disabled person needing to enter a building or structure that is at a height of approximately two to three steps. The device is also useful for material handlers. This design has three key enablers. The first key enabler and most critical to the design is a two-stage lift mechanism. The first stage provides considerable leverage albeit at a slower lift speed to initially raise the platform from a low-profile position. The low-profile position is necessary for ease of ingress onto or egress off of the lift platform. The second stage provides increased vertical lift speed to the desired top position. The second key enabler is the light-weight design. The third key enabler is the compact design.

Abstract: A cable pulling system and associated method are shown. Examples include positioning joints that allows a pulling boom to move up or down and side to side, while maintaining alignment of a pulling cable between pulleys. Example methods include positioning a pulling boom within a conduit box and pulling an electrical cable through a conduit into the conduit box.

Abstract: An adjustable clamp has first and second handles that are pivotally joined together and first and second jaws that extend respectively from the first and second handles and end in first and second nose tips.
