Provided is a lifting control device that can quickly make lifting determinations while suppressing load vibration. The lifting control device D comprises: a boom 14 that is configured to be freely raised and lowered; a winch 13 to hoist and lower a suspended load via a wire rope 16; a load measurement means 22 to measure the load acting on the boom 14; and a controller 40 that controls the boom 14 and the winch 13, wherein when lifting a suspended load from the ground by winding up the winch 13, the controller 40 retains a maximum load value from a time series of load data as a variable, finds variations in the hoisting angle of the boom 14 on the basis of time variations in the maximum load value, and raises and lowers the boom 14 so as to compensate for the variation.
