MAST GRADIENT CONTROL SYSTEM FOR A FORKLIFT TRUCK, A CIRCUIT, AND A METHOD THEREOF, CAPABLE OF PREVENTING LOADED CARGO FROM FALLING

摘要

PURPOSE: A mast gradient control system for a forklift truck, a circuit, and a method thereof are provided to fix the gradient of a mast by comparing the gradient of a mast measured by a mast gradient measuring unit with the gradient of the mast preset in advance.;CONSTITUTION: A mast gradient control system for a forklift truck comprises a gradient sensor(10), a mast control circuit(30), and a height sensor(20). The gradient sensor measures the gradient of a mast(100) and outputs the gradient signal. The mast control circuit outputs the control signal for controlling the gradient of the mast on the gradient signal. The mast control circuit outputs the control signals to maintain the gradient of mast within a preset range. The height sensor measures the height of the fork which is coupled with the mast and loads cargo. The height sensor outputs signals.;COPYRIGHT KIPO 2010
