The purpose of the invention is to provide a crane device, a method for determining the number of falls, and a program with which, without increasing the number of parts, it is possible to determine whether the actual number of falls for a rope and the number of falls for the rope set by an operator are the same.A crane device is capable of setting multiple types of number of rope falls between a tip of a boom and a hook block, and includes: a feed length detection unit that detects a feed length of a rope fed from a winch on which the rope is wound; a boom angle detection unit that detects a boom hoist angle; and a number-of-falls determination unit that calculates information for determining the suitability of the number of falls for the rope on the basis of the feed length, hoist angle, boom length of the boom in a state of hoisting a grounded load.
