  • Patent number: 11673667
    Abstract: To reduce strain and mitigate fatigue in an aircraft's airframe, some example dynamic load-sharing systems provide the aircraft with multiple tension devices that share the weight of a load hanging from the aircraft. In some examples, the tension devices are installed in the aircraft's cabin space to protect the surrounding airframe by transmitting a portion of the load's weight directly from the floor to the ceiling of the aircraft. In some examples, the portion of the weight transmitted by the tension devices is proportional to the load's total weight. In some examples, the tension devices are piston/cylinder devices that are interconnected by a manifold to distribute the load equally among the tension devices. Some examples of dynamic load-sharing system include a pressure relief valve and/or an accumulator that limits the maximum load applied to each tension device.

  • Publication number: 20140263143
    Abstract: A lifting system for semiconductor processing equipment utilized in a cleanroom environment. The lifting system comprises of an articulating arm, a base, a load indicator, a capture tool and a wirelessly controlled hoist motor unit with float control. The float control allows precise positioning and movement of the load without requiring use of up and down controls of the wireless remote. Covers and the bellows positioned on and coupled with the arm assembly reduce contamination caused by a wire rope extending from the arm. A load indicator shows the system coming under load while holding the load stationary. A capture tool provides quick release and ease of grabbing the load with the use of a capture pin. A rotary electrical collector provides a full 360 degrees of rotation of the articulating arm from the base, in both directions. This lifting solution provides high cleanliness and ease of use.

  • Patent number: 7706947
    Abstract: A forward-control counterweight fork-lift truck has a liftable and tiltable load-lifting device (1), a traction drive and operating drives for the movement of the load-lifting device (1). A calculation model (D) is stored in a control device (SE), to which directly or indirectly acting sensors (S) are connected for detecting the lifting load (L), the lifting height (H), the tilting angle (WM), the load torque (M), the direction of travel (R), the driving speed (V), and the steering angle (WL). The control device (SE) is designed to determine a driving and load state (Z) based on the detected physical variables (L, H, WM, M, R, V, WL) and the stored calculation model (D) and is operatively connected to the traction drive and the operating drives. Depending on the driving and load state (Z) determined, the operating speed, starting and braking acceleration, and driving speed are each reduced.
