Japanese Patent JP7439850

B2

A storage unit (51) stores lifting height difference information pertaining to a lifting height difference (ΔL) associated with the magnitude of the hoisting angle (θ) and the magnitude of a lifting load (F) of an attachment (14). The lifting height difference (ΔL) is the difference between a lifting height calculation value (Lc) and the actual lifting height (L) of a hook (19b). A computation unit (53) calculates the lifting height calculation value (LC) on the basis of a hoisting angle detection value, which is the hoisting angle (θ) detected by an attachment angle sensor (35), and hoisting amount detection value, which is a hoisting amount detected by a hoisting amount sensor (37). The computation unit (53) uses the lifting height difference information to determine a lifting height difference correspondence value, which is a lifting height difference (ΔL) corresponding to the hoisting angle detection value and a lifting load detection value, which is the lifting load (F) detected by a lifting load sensor (33), and corrects the lifting height calculation value on the basis of the determined lifting height difference correspondence value.
