Abstract: A portable personal descending escape system that includes a flexible, folding body sack designed to hold a small child or animal that can be gradually lowered to the ground by a single individual. The body sack is designed to fold into a small storage bag. The body sack includes a closable top opening and at least one side panel partially made of mesh material. A slide connector is disposed around the joining edges of the top opening that allows the top opening to be selectively opened or closed. Attached to the opposite sidewalls on the body sack near the top opening are two handles. Attached to the body sack is an elongated strap with a plurality of strap handles attached thereto. The strap handles are evenly spaced apart so that one individual may gradually release the handle to safely lower the child or animal to the ground.
Abstract: A floating dock mover that utilizes electrically powered devices to aid in relocating a floating dock whenever water levels change in a lake or reservoir. Electrical powered winching mechanisms are used to adjust cables lengths to maintain a position, or aid to obtain a new position of the dock in relation to the shoreline. Additionally, a motorized speed reducer is used to turn the wheels on the dock walkway, which moves the walkway and dock away from, or toward the shore. By electrically powering winch cable lengths, plus electrically powering the walkway wheels, the dock can be relocated horizontally and vertically and maintain a relative desired position in relation to a moving shoreline. An additional electrically motorized unit is used to operate an anchor which aids in maintaining a dock in a desired position.
Abstract: A cargo lifting apparatus for use with a ladder includes a lift track coupled to each ladder side rail. Each lift track includes first and second adjacent channels, the first channel defining a longitudinal slot. The apparatus includes a carrier assembly having a back portion, a pair of support members extending perpendicularly and forwardly from the back portion, opposed mounting members configured to be received in a respective first channel slot, and rollers attached to the back portion configured to bear against respective ladder side rails. A motor/brake combination is coupled to a lower rung of the ladder. A pulley assembly includes a lower sprocket operatively coupled to the motor, an upper sprocket, and a cord extending between the sprockets and coupled to the carrier assembly for selectively raising and lowering the carrier assembly when the motor is activated or deactivated.
Abstract: An aerial rescue device is a powered platform that quickly elevates the fireman to height, or powers the secure descent of a rescued person. A powered carriage rides between two extensible booms. Two rungs secured to the carriage enable a fireman to stand on one and hold onto the other. The two booms have rails within. The rails guide trolleys secured to the ends of the two rungs. The carriage is moved by two cables. Each cable is connected at one end to the carriage and at the other end to two winches. These winches are computer controlled to enable the carriage to ride up and down while the booms are being extended. Preferably, there are also rotatable boom segments at the top of the booms.
Abstract: A device is provided for aiding a user in transporting a load up and down a ladder assembly. The ladder assembly includes a fly ladder having slidably connected to a base ladder. Each ladder includes first and second spaced rails interconnected by a plurality of spaced rungs. The device has a frame assembly including a first subframe positionable adjacent the first rail of the base ladder and a second subframe positionable adjacent the second rail of the base ladder. First and second base ladder guides are operatively connected to each subframe and define tracks for receiving the rails of the base ladder therebetween. First and second fly ladder guides are operatively connected to the subframes and defines tracks for receiving the rails of the fly ladder therebetween.

Abstract: A stepladder comprises a front frame and a rear frame each formed of a pair of spaced side rails. A motor-driven step is slidably mounted on the front frame side rails. The motor is controlled with a remote unit allowing a worker to automatically raise and lower the step when accessing an elevated area.
Abstract: A mobile mount for attachment of a fall arrest system. The mobile mount includes a mobile base, a support, at least one base, at least one arm and at least one anchor. The mobile base has a first side and a second side. The support extends upward from proximate the first side of the mobile base. The support also has a first end coupled to the mobile base and a second end. The at least one brace is coupled between the support and the mobile base to maintain the support in an upward position in relation to the mobile base. The at least one brace is slideably coupled to the mobile base. The at least one arm assembly is coupled to the second end of the support and extends from the support so as to be cantilevered over the mobile base. The at least one anchor is configured to be attached to the fall arrest system. Moreover, the at least one anchor is coupled to the at least one arm assembly.
Abstract: A device for a gangway construction is described, which is characterised in that it is composed of a number of sections, each comprising a polygonal frame, one connected to the frame formed as a landing, and a gangway, the one end of which is hinge-connected to the frame/landing while the other end is set up to rest against the frame/landing of an underlying frame, and the construction is arranged to be readjusted between a folded position where the sections are lying on top of each other, as in a stack of frames, with each gangway inserted in the frame, and an active, using position where the frames are set up a distance apart so that the gangways form a suitable angle between adjoining landings/frames. Also described are a section for building a gangway construction, a railing construction and also applications of the invention.

Abstract: The invention relates to a climbing aid for ladders or the like, comprising an endless traction means running between guide pulleys, from which a person may optionally hang by means of a suspension device, with a drive device (20) comprising a drive motor (21), by means of which one of the guide pulleys may be driven as the drive disc (12) for the drive means (13), with a traction force limitation device and with a device for switching the drive device on/off, which can be actuated by the endless traction means (13).
Abstract: This invention is a self-hoisting platform which can be used by painters, carpenters, or the like when painting or repairing elevated building structures. This is accomplished through the provision of a seat-like means having an interconnected dual lift system with reversible, pawl type locking means for manually raising and lowering the system.
Abstract: A pedestal scaffold having casters on the scaffold base to permit the scaffold to be rolled horizontally while the scaffold is in a generally vertical position. Retractable outriggers are extended outwardly and locked in position to provide a large support area for the scaffold, with the act of extension and locking of the outriggers causing the casters to lift off the ground so that the scaffold cannot be moved when in use. When the outriggers are not in use and the scaffold is movable on its casters, the casters support the scaffold with a substantial tilt from elevation so that it cannot be used. Additional wheel support frames are provided so that the scaffold can be tilted down for rolling transport, such wheel support frames also serving to protect the user in case the scaffold should tip over when it is generally vertical and supported on its base casters.
