The patent US12054369B2 describes a hoist designed for lifting and lowering loads, featuring a unique upper hook structure and support system. The hoist includes an upper hook with a hook base that has a first insertion hole, through which a first support shaft is inserted. This support shaft consists of a hook-side large-diameter portion, end large-diameter portions, and an intermediate portion that contains a strain deformation section with a reduced cross-sectional area. This design allows for the measurement of shear loads acting on the strain deformation portion through an attached load measurer. The main frame of the hoist is supported by the upper hook via the first support shaft, ensuring stability during operation.

Additionally, the hoist incorporates a second insertion hole and a second support shaft, both aligned parallel to the first. A retainer is included to prevent the first support shaft from disengaging from the support holes. The load measurer is connected to a circuit board through a connection line, which is routed along the axial direction of the first support shaft and through a lateral groove. This configuration enhances the hoist's functionality and safety by ensuring that the load measurement system is securely integrated and protected from potential disconnections during use. The design elements outlined in the claims contribute to the overall efficiency and reliability of the hoist in various lifting applications.
