Abstract
Description
Technical Field

[0002] The OPS (Operator presence sensing) control system for heavy forklifts is an operator perception system, which is mainly used for safety protection. When the operator is not in the correct operating position, the operator will not be able to perform any operation on the vehicle, thereby preventing safety accidents caused by misoperation. At present, the OPS system commonly used in the manual valve system of domestic forklifts is to add a unloading solenoid valve to the main oil channel of the hydraulic main valve and an oil circuit blocking solenoid valve to the fork lowering circuit. When the operator leaves the seat or is not in the correct operating position, the controller judges and energizes the unloading solenoid valve and the oil circuit blocking solenoid valve on the main valve through the input signal of the seat gravity sensor, thereby realizing the main system unloading and fork lowering circuit blocking, realizing the effect of no action output of the operating handle fork lifting, front and rear tilting, and left and right fork adjustment, and achieving safety protection. However, the above method requires changing the oil channel design of the main valve, involving main valve changes, valve body mold opening, etc., which is costly, and the main valve needs to have a customized design, which cannot be universal with conventional components of other product lines, and is easily limited when selecting solutions.
