ABSTRACT:
A system for controlling a lift truck apparatus with a clamp, the angle of which is set by a rotator, is disclosed. The rotator is provided with an angle sensor for detecting its rotational angle position, and the clamp is provided with a clamp pressure sensor for detecting the clamp pressure. A plurality of selection switches operable in an auto mode are provided on an operation panel for rotator control and clamp control. These selection switches designate memory areas of angle memory means and pressure memory means. By selectively operating the selection switches, corresponding angle data and pressure data are read out from the angle and pressure memory means. A clamp operation of the clamp is executed according to pressure data read out according to operation of an operation lever. Also according to the operation of the operation lever angle data is read out to control the rotator so as to control the angle of the clamp.
