    摘要: A roofing materials removal device provides a guide system which secures the device and the operator in position on an inclined roof so that the roof can be traversed at various positions along different travel paths while supported. The removal device comprises a light-weight, durable, wheel supported frame, dual handles for leverage, an electric motor positioned low on the frame to give the device balance and stability. An angled blade reciprocating and riding on linear bearings is connected to spring-mounted tension bars. As the springs force the rear end of the tension bar upward, the forward end of the tension bars pivot downward causing the serrated, leading edge of the blade to slide between the roof covering material and the roof deck. The blade follows the contour of the roof deck dislodging roofing material including nails, roofing felt and shingles. The guide system is positioned on the opposite side of the roof ridge from the removal device. The guide system comprises a track, a vertical support post assembly, a carrier which traverses the length of the track, and an adjustable support system which secures the machine frame and the operator to a desired position. An on-off ramp allows the roofing materials device to be moved to the desired position through the use of the guide system.

    摘要: A portable conveyor system comprises an extensible and retractable boom assembly mounted on a transportable stationary support. The boom assembly comprises a plurality of longitudinally spaced rungs defining a series of supporting surfaces for a primary load carrier of the type described in applicant's co-pending U.S. patent application Ser. No. 75,410, now U.S. Pat. No. 4,793,437. The improvements described herein include a vertically adjustable hitch mounted forwardly on a frame of the primary load carrier. The hitch is adapted for attachment to the end of the cable of a winch assembly to move the endless tracks of the carrier in full contact along the supporting surfaces of the rungs. Other improvements include modified boom and overhead bracket assemblies, a resilient suspension system for the primary load carrier and a platform assembly attachable to either end of the boom assembly to alternately function as a loading or unloading platform.

    摘要: A pair of truck vehicles are manually moveable along the top and side edge running surfaces of parallel joist members of a factory roof a-building. Each truck runs on a separate joist and each has wheels running on the top surface of the joist with horizontal axles journaled to the truck chassis and has pairs of guide wheels with verticle axles journaled to the chassis and running on top side edge of the joist. The trucks carry between them bundles of corrugated sheet steel roof decking for manually and sequentially fitting to the roof of the factory from the trucks.

    摘要: A telescopic beam for use in an inclined hoist has five telescopic members. An actuator comprising a motorized winch and a block and tackle arrangement is provided for extending the telescopic members relative to one another. The block and tackle arrangement includes a cable which passes several times around sets of rollers positioned at the adjacent ends of first and second of the telescopic members. A lock is provided for fixing the positions of the first and second telescopic members. To relieve the operator of the need for controlling several actuators, the single actuator is used to control the extension of all the telescopic members, and to control the angle of inclination of the last telescopic member relative to the penultimate telescopic member. For this purpose, the cable is passed from the second telescopic member to the far end of the penultimate telescopic member, and then to the adjacent end of the last telescopic member where it is secured.
