摘要

PROBLEM TO BE SOLVED: To provide a cable reel controller, a method for controlling a cable reel, and a tire type crane for winding and rewinding a cable while stabilizing tensile force acting between a vehicle running by the cable reel and the external.;SOLUTION: This controller 20 for the cable reel 5 includes a displacement measuring means 21 for measuring displacement of the cable extended from a drum 5b, a tensile force computing means 30 for computing a value Fe of the tensile force acting on the cable based on the displacement of the cable 4 measured by the displacement measuring means 21, and a motor torque computing means 31 for computing a torque command value Ct being torque to be generated by a motor 5b by correcting a reference torque value Ts corresponding to a set tensile force value Ff set in advance as the tensile force acting on the cable by a torque correction value ▵T obtained from the difference between the tensile force value Fe computed by the tensile force computing means 30 and the set tensile force value Ff and outputting the obtained torque command value Ct.;COPYRIGHT: (C)2010,JPO&INPIT
