Abstract: The invention relates to a crane, in particular a rotary tower crane, comprising a crane boom, from which a load hook can be raised and lowered via a hoist cable, and an electric power supply on the load hook and/or an optionally provided trolley which can be moved on the crane boom. According to the invention, the electric power is directly generated at the location where it is required, and in the process kinetic energy present at said location is converted into power. According to the invention, the electric power supply comprises a generator which is arranged on the load hook and/or on the trolley and which can be driven by a deflecting and/or running pulley and/or a cable running around the deflecting pulley.

Abstract: The present invention relates to a crane, in particular a tower crane, with a boom rotatable about an upright slewing gear axis and an out-of-service brake which permits and slows down the rotary movements of the boom in the out-of-service condition. According to the invention, the out-of-service brake is formed to operate in a rotational-speed-dependent manner such that with a greater rotational speed of the crane the applied braking torque is greater than with a smaller rotational speed of the crane.

Abstract: Two embodiments (FIGS. 1 and 4) of a portable crane/winch/hoist allowing a safe flexible use with attachments to a vehicle or other designated use area while simple to assemble/disassemble with it's relatively light weight sections allows for a one person assembly and operation, is not intrusive to a vehicle's body nor is permanently attached and exposed to the elements. This device allows for a safe operation to load and unload objects while not being risky for a strain or injury when attempted by only one person in lieu of requiring two or more persons to accomplish the task. By reducing the injury risk thus limiting the potential for missed work hours and insurance claims; should result in enhanced performance production and insurance friendly rates. Additionally, this device can be adapted to shop work benches and other areas, as well as multiple vehicles particularly in the service industry i.e.; delivery, electrical, HVAC, plumbing, lawn equipment, recreational vehicles, SUV's, vans, boats/motors. The present invention, being sectional, is relatively easy to manufacture, assemble, operate, disassemble and store. Said device is “user friendly” and economically affordable considering the existing products presently in the industry.

Abstract: A scaffold mounted hoist (20) is provided which mounts with an adapter (30) on a pin (91) extended upward from the scaffold. An electric motor driven transmission (42) causes a standard (40) to rotate relative to the adapter. A cable from an electric winch (50) on the standard is reeved through a pulley (48) on a boom (44) extending from the standard. The transmission and winch motors respond to receivers (56) in the hoist. Thus a load (28) attached to the cable can be lifted, lowered and swung circumferentially through commands from a hand held transmitter (24). An electric eye system (64) stops the load adjacent the boom. Timers (252, 253) stop the load when it nears, respectively, the ground and the scaffold floor (34).

Abstract: A jib crane system comprising a horizontally extending load beam rigidly attached to the upper end of a vertically extending mast. The lower part of the mast is positioned inside a hollow structure such as a pipe and is rotatably associated therein, and spaced from the inside surface of the pipe. A bearing boot is rigidly secured to the mast and in frictional contact with the inside surface of the pipe. The bearing boot slides around the inside circumference of the pipe in a circular or arcuate path as the mast and load beam revolve around the central axis of the mast. The bearing boot includes an outer arcuate concave contacting plate having substantially the same radius as the inside convex surface of the pipe. A ring of foil may be secured on the inside of the pipe for providing the sliding surface for the bearing boot. The mast may comprise a flanged beam having a pair of side walls with a web portion therebetween. The web may be split at the upper part thereof into two sections which are angularly spaced apart and the split sections attached at their upper ends to the rear end of the beam. Alternatively, a rod means may be secured at the upper end to the rear end of the load beam and extending angularly downward and inward therefrom for attachment to the mast at the lower end thereof.

Abstract: The invention concerns a kinematic system of an industrial robot and a sequential control system of its operating cycle.The robot comprises a vertical spindle supporting a main rotating arm and a forearm fixed to a gripping component. A first vertical transfer jack is provided at the end of the forearm. Arms are mounted via bearings on a loose spindle in a link and can swivel, driven by servo-motors in a horizontal plane so as to form a kinematic system functioning in cylindrical coordinates. The servo-motors are programmed to drive the gripping component through a linear trajectory at the beginning of the cycle. A releasable couping system with memory device is provided for the tool-holder. The controller control system is arranged to ensure the transitory readjustment of each arm to a starting position.
