Latest Patents

One of Tokutome's latest inventions is a boom slewing angle detection device for mobile cranes. This device features a slewing angle detecting gear attached to the end of a shaft of a pinion gear that meshes with a ring gear on a slewing bearing supporting the crane boom. The device utilizes a slewing-angle-detecting proximity sensor to accurately detect the rotation of the slewing angle detecting gear. Notably, this gear is not meshed with the ring gear or pinion gear, preventing grease and other substances from adhering to it, which ensures that the external teeth remain free from wear and allows for precise slewing angle detection.

Another significant patent involves a crawler crane that includes a seating switch to detect whether an operator is in the driver seat, a turn angle potentiometer to monitor the boom's turn position, and a controller. The controller is equipped with a boom turn restriction control unit that restricts the boom's movement within a predetermined angular range above the driver seat based on the output from the turn angle potentiometer. This system improves ease of operation and work, especially in remote operation modes, by canceling the boom turn-restricting control if the seating switch does not detect an operator.
