摘要： A load weight measuring device for a multi-stage mast forklift truck has a mast assembly, an oil passage, a flow regulator valve, a pressure sensor, a detecting device, a memory, a selector, and a calculator. The mast assembly has a lift bracket for receiving a load weight, a multi-stage mast unit having masts, and a multi-stage lift cylinder unit having lift cylinders each having an oil chamber for raising the lift bracket along the masts. Hydraulic oil flows in the oil passage. The pressure sensor detects a pressure of hydraulic oil and outputs a pressure signal. The detecting device detects a state which stage of the lift cylinder raises the lift bracket and outputs a detection signal. The memory stores predetermined parameters from which the selector selects the parameter based on the detection signal. The calculator calculates the load weight based on the selected parameter and the pressure signal.

摘要： A lift vehicle and a method for initializing a controller for controlling a lifting mechanism of lift vehicle. The controller controls the maximum forward tilt angle of a mast by controlling a solenoid of a hydraulic circuit. The controller employs a stored map or equation that defines a relationship between the forward tilt limit and another parameter. When the mast is tilted at two degrees, a CPU reads the detection value of a tilt angle sensor and sets it as a reference value. The reference value is used to calibrate the controller. The same function information can be used for many types of lift vehicles by selecting the appropriate control ranges for each vehicle.
