PROBLEM TO BE SOLVED: To provide a counterweight support device for a crane, capable of suppressing cost when installing and removing the counterweight support device, causing no problem in following performance of a counterweight even in a simply conditioned working site environment, without requiring preparation of the counterweight support device for every crane, and without requiring a wide space for installing the counterweight support device. SOLUTION: This counterweight support device includes a pallet 200 for placing the counterweight 250, and a transporter 100 for moving the pallet 200 in a state that the transporter 100 lifts up the pallet 200, a leg portion of the pallet 200 is telescopically formed, and a travel unit 106 arranged in the transporter 100 is also constituted so as to be telescopic in the vertical direction. When the crane turns, turning direction information and turning angle information are transmitted to the transporter 100, so that a receiving portion of the transporter 100 receives the information, and the transporter 100 moves in response to the information.
