Title: Innovations of Jae Hoon Lee in Construction Equipment

Introduction

Jae Hoon Lee is a notable inventor based in Changwon-si, South Korea. He has made significant contributions to the field of construction equipment, holding a total of five patents. His work focuses on enhancing the functionality and efficiency of traveling systems in heavy machinery.

Latest Patents

One of his latest patents is a traveling system for construction equipment. This system is designed to secure initial traveling manipulability, regardless of whether the equipment is moving at low or high speeds. When high-speed traveling is selected, the inclination angle of a swash plate in a hydraulic pump is variably controlled. This allows the discharge flow rate of the hydraulic pump to exceed a predetermined flow rate compared to low-speed traveling.

Another significant patent is a traveling device for crawler-type heavy equipment. This device improves manipulability by preventing abrupt changes in traveling speed during combined operations, where both the left/right traveling device and a working device are driven simultaneously. The device includes a variable orifice that intercepts the supply of hydraulic fluid to the traveling device based on signal pressure in the combined working mode, especially when the load pressure of the working device is higher than that of the traveling device.
