Abstract

The present invention relates to a device for driving a crane boom assembly. Said device for driving a crane boom assembly has a main boom, a plurality of inserting and withdrawing booms combined inside said main boom to insert and withdraw, a cylinder device for allowing some of said inserting and withdrawing booms to insert and withdraw, wires for allowing the rest of said inserting and withdrawing booms to be operated, and pulleys on which said wires are wound, wherein the device for driving a crane boom assembly comprises: a first cylinder which has a first rod that is fixed to said main boom, and a first cylinder body into which said first rod is inserted to emerge therefrom and which is fixed to a inserting and withdrawing boom, in order to allow said first inserting and withdrawing boom to insert and withdraw from said main boom when said first inserting and withdrawing boom to an Nth inserting and withdrawing boom (N is a natural number which of 4 or more) are sequentially inserted into the inside of said main boom; a second cylinder which has a second rod that is fixed to a second inserting and withdrawing boom, and a second cylinder body into which said second rod is inserted to emerge therefrom and which is fixed to a third inserting and withdrawing boom, in order to operate simultaneously with said first cylinder body and to allow said third inserting and withdrawing boom to insert and withdraw from said second inserting and withdrawing boom; a first wire having one end that is coupled with said main boom, and the other end that is coupled with said second inserting and withdrawing boom; a first pulley which is installed on said first inserting and withdrawing boom, and guides said first wire by hanging said first wire; a second wire having one end that is coupled with said second inserting and withdrawing boom, and the other end that is coupled with said main boom; and a second pulley which is installed on said first inserting and withdrawing boom, and guides said first wire by hanging said first wire.
