Title: Innovations by Tatsufumi Tomura

Introduction

Tatsufumi Tomura is a notable inventor based in Nagano, Japan. He has made significant contributions to the field of mobile cranes, holding a total of 3 patents. His work focuses on enhancing the functionality and safety of crane operations.

Latest Patents

One of his latest patents involves a mobile crane that features a seating switch to detect whether an operator is in the driver seat. This innovation includes a turn angle potentiometer that monitors the boom's turn position. The controller is equipped with a boom turn restriction control unit, which restricts the boom's movement within a specific angular range above the driver seat based on the output from the turn angle potentiometer. If the seating switch does not detect an operator, the boom turn restriction control is canceled, improving ease of operation in remote operation modes.

Another patent focuses on a crawler crane where a fly jib is suspended from a coupling flange by a jib raising/lowering wire rope. This wire rope is wound around a sheave that is slidably attached to the tip end of the fly jib. The design allows the fly jib to incline with respect to the boom when the sheave is moved by a jib raising/lowering cylinder, facilitating easier extraction and storage of the fly jib.
