Description of the Invention: [Technical Field] The present invention relates to a crane, and more particularly to a crane that uses an cantilever mounted on a tower to hang an object. [Prior Art] Referring to Figures 1 and 2, conventional cranes generally include a bottom frame 11 placed on the ground, a rotating mechanism 12 mounted on the bottom frame U, and a rotating mechanism 12 disposed thereon. The column 13, a cantilever 14 that is erected transversely above the column 13, a suspension unit 15 that suspends the cantilever 14, and a spreader 16 that is movably suspended below the cantilever 14. The bottom frame 11 has two parallel lower beam columns 111, and two upper beam columns 112 vertically erected above the lower beam column hi and mounted by the rotating mechanism 12, the cantilever 14 having one erected on the column a fulcrum portion 141 above the 13, a hanging arm portion 142 protruding from the fulcrum portion 141 in the horizontal direction and mounted to the spreader 16, and a horizontal extending from the fulcrum portion 141 in a direction opposite to the hanging arm portion 142 The balance arm portion 143 has a weight hanging end 144 away from the fulcrum portion 141. In order to allow the boom 14 to maintain balance during use, the crane also includes at least one weight 17 placed on the weight end 144 of the boom 14, which may be concrete or steel, etc. . When the conventional crane 1 is used, the balance relationship of the cantilever 14 is calculated according to the weight of the hanging object and the position of the hanger 2, and then the weight is appropriate. The counterweight & 17 suspension of the concrete or steel plate, etc.; is hung on the counterweight end 144 to maintain the balance of the entire crane when the object is suspended. Such a long time used in the 201124333 period, such as the match, the aunt, the aunt, is the use of the square /,,, ° to achieve the purpose of maintaining balance 'but the method must first produce a variety of weights of the weight η, and then The truck will transport the weight of the weights 17 to the construction site with the weight of the truck. After use, the truck will carry the weights 17 away from the construction site, which is inconvenient and will increase the cost during construction. In addition, the conventional crane i can use the upper and lower masts 112, 111 to increase the stability of the bottom frame u when placed, but since the crane L usually hangs relatively heavy objects such as steel bars, When used, it is easy to cause the bottom frame 11 to be skewed and unstable. In order to increase the safety and stability of the crane 1, the general operator will usually display the metal plates of the beam and column U1 ± at the interval, and then press on the plate 18 Put some cement blocks 19 with weight. Although it is feasible to increase the stability of the crane raft by the cement block 19, these cement blocks 19 must also be transported by trucks. After the completion of the project, these cement blocks 19 have no other use and must be removed from the construction site. The method of increasing the stability also has problems such as inconvenient use and high construction cost. [Invention] The object of the present invention is to provide a crane that can increase the stability and balance of the display while reducing the construction cost. . The crane of the present invention comprises: a base, a tower column disposed on the base and a cantilever unit, the base comprising a bottom frame, and at least one stabilizing box disposed on the bottom frame, the stabilizing box Having a stabilizing chamber wall defining a stabilizing chamber for placing water, sand, gravel, etc.; 201124333 and the cantilever unit having a cantilever, and at least one balance arm having a erection Phase, one of the opposite sides of the suspension hangs the arm-shirt/pivot portion. a balance arm, the balance on the balance arm, and a balance box wall defining a balanced chamber for the placement of water, stones, and the like. The beneficial effect of the invention is that: by the balance box of the cantilever balance chamber, there are thousands of boxes per month, and the stabilization of the room can be set on the bottom frame.
