Described track adjusting wheel B is fixedly installed on the apical position of basic arm.
Described track adjusting wheel A is positioned on basic arm near middle position.
Described basic arm is box-structure.
Reel B on described tower body is positioned at the top of reel A.
Described folded boom arm is telescopic boom.
The two ends of described amplitude oil cylinder are hinged in basic arm and folded boom arm respectively.
The beneficial effects of the utility model: the utility model in the course of the work, reel A and reel B controls basic arm respectively by steel rope A and steel rope B and folded boom arm carries out luffing action, amplitude oil cylinder is fore and aft motion along with the luffing motion of folded boom arm, reel C drives the weight below suspender to carry out lift work by steel rope C simultaneously, because the basic arm of arm-folding crane and the luffing of folded boom arm are all controlled by steel rope, so the lifting operation of super-heavy load can be realized, the telescopic structure of folded boom arm can increase the swinging radius of crane hanging component operation in case of need, when hoisting crane does not work, basic arm is put suitable position by steel wire A rope by reel A, by the action of amplitude oil cylinder, folded boom arm is folded into completely the below of basic arm simultaneously, easy to use, conserve space, the utility model has compact conformation, conserve space, and can realize the advantage of super-heavy load lifting operation.
Accompanying drawing explanation
Fig. 1 is the structural representation of a kind of folding-jib crane of the utility model.
In figure: 1, pedestal 2, pivoting support 3, basic arm 4, tower body 5, reel A6, reel B7, steel rope A8, steel rope B9, reel C10, steel rope C11, track adjusting wheel A12, track adjusting wheel B13, folded boom arm 14, suspender 15, amplitude oil cylinder.
