Latest Patents

One of Okubo's latest patents is a seismic isolation system for a crane. This innovative system features a swing bearing ring consisting of an upper and lower ring that rotate relatively between the crane body and the traveling means. The design includes a lower vertical shaft of a block that is pivotally supported on saddles of the crane body, which is supported by a swing bearing positioned eccentrically on the upper ring. Additionally, an automatic restoring mechanism is integrated to restore the swing of a horizontal lever attached to the upper ring.

Another significant patent is the swaying hoisted load-piece damping control apparatus. This system includes a transverse trolley that is movable on a crane girder, equipped with drivers for the trolley and sheave blocks. Detectors are utilized to monitor the displacement and velocity of the trolley, sway displacement, and the velocity of the hoisted load-piece. The system is designed to optimize sway-damping control based on detection signals, enhancing the safety and stability of crane operations.
