Latest Patents

Truehart holds a patent for a "Divided Flow Self-Leveling System." This invention is a load self-leveling system for vehicles that utilizes hydraulic cylinders to operate a telescopic lifting boom and a material handling carriage. The system features a pair of fluid flow dividers that are strategically placed between the source of hydraulic fluid under pressure and the hydraulic cylinders. These flow dividers are designed to direct a greater flow of hydraulic fluid to the boom cylinder while allowing a lesser flow to the carriage cylinder. The precise numeric proportions of flow division are engineered to suit specific vehicles and their componentry. Additionally, the system includes reversible flow piloted check valves, override control with relief valves for independent adjustments, and matched cylinder area ratios. A compact assembly housing various components of the system is also disclosed in the patent.
