In a truck crane attached with a flexible connecting pin, an arm 2 is protruded laterally from one side of the base of the rooster sheave support 1, and the rooster sheave support 1 is moved to the tip of the boom using the connecting pin 3 on the side where the arm is attached as a fulcrum. When the arm 2 is rotated by a certain acute angle from its mounting position, a bracket 5, which can pivot the tip of the arm 2 with a connecting pin, protrudes and is fixed to the corresponding side wall plate 6 of the pulley attachment part for hanging the hook block, and the above-mentioned position of the arm 2 and the bracket 5 is When the rooster sheave support plate 1 is folded onto the corresponding side wall plate 6 using the connecting pin as a fulcrum,
A folding device for a rooster sheave base, characterized in that a separable coupling means is provided for coupling the two with a coupling pin 3. (2) In the folding device for a rooster sheave support base set forth in claim (1) of the utility model registration, the folded rooster sheave support base is located inside the maximum locus of the boom tip of a truck crane that rotates with a minimum turning radius. The size of a constant acute angle is set so that the
