The invention discloses an amplitude control device and method for an overhead working truck. The device comprises a first magnetostrictive sensor and a second magnetostrictive sensor, wherein the first magnetostrictive sensor is arranged in a variable-amplitude oil cylinder and used for measuring the length of the oil cylinder of the variable-amplitude oil cylinder; the second magnetostrictive sensor is arranged in a telescopic oil cylinder and used for measuring the length of the oil cylinder of the telescopic oil cylinder; the bottom of the variable-amplitude oil cylinder is hinged to the rotary table, and the extending end of the variable-amplitude oil cylinder is hinged to the lower portion of the working arm. The bottom of a cylinder barrel of the telescopic oil cylinder is hinged to the working arm tail, and the extending end of the telescopic oil cylinder is hinged to the working arm head. The rotary table is in shaft hinge joint with the working arm, and the first magnetostrictive sensor and the second magnetostrictive sensor are electrically connected with the vehicle-mounted controller; the magnetostrictive sensor is arranged in the oil cylinder, so that the risks of external damage, measurement data damage and manual disassembly are avoided; the influence of external vibration on data is very small; the detection precision of the magnetostrictive sensor belongs to the micron level and is improved by one order of magnitude compared with the millimeter level of a length sensor; the angle and length detection of the overhead working truck is more direct and accurate, and the control precision is higher and more intelligent.
