Patent number: 11673667Abstract: 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.Type: GrantFiled: October 9, 2021Date of Patent: June 13, 2023Inventor: Travis G.

Publication number: 20140263143Abstract: 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.Type: ApplicationFiled: March 15, 2013Publication date: September 18, 2014Applicant: THE CARPENTER GROUPInventors: Dane Oliver, Ben Jones, Steven J.
