Abstract

The invention discloses balance weight equipment of a crane. The balance weight equipment is arranged on a turntable of the crane and comprises a balance weight which is arranged at the bottom of the rear side of the turntable in a rotatable manner, a driving device which is connected with the turntable and the balance weight respectively and is used for driving the balance weight to rotate for a preset angle, and a locking device which is connected with the driving device to allow the balance weight to keep a static state at the preset angle. According to the balance weight equipment of the embodiment disclosed by the invention, an anti-tilting moment can be changed by changing the gravity center of the balance weight relative to the position of the crane; the locking device can keep the balance weight in the static state at the preset angle, so that the back-movement of the gravity center of the balance weight is avoided, and the potential safety hazard is eliminated; therefore, the workability of hoisting of the crane is improved under the situation that the balance weight is not increased, and the stability and the safety of the crane are improved. The invention also discloses the crane with the balance weight equipment.

Description

technical field [0001] The invention relates to the field of automobiles, in particular to a crane counterweight device and a crane with the same. Background technique [0002] The counterweights of truck cranes currently on the market are mainly fixed counterweights, which are directly fixed to the lower part of the turntable by bolts, so the center of gravity is stationary relative to the turntable and the distance from the center of rotation remains unchanged. As the truck crane operates under different working conditions and amplitudes, the tipping moment will increase with the extension of the crane jib and the increase of the amplitude of the weight. Obviously, the fixed weight without increasing the weight cannot achieve the function of improving the stability of the whole machine. Contents of the invention [0003] The present invention aims to solve at least one of the technical problems existing in the prior art. [0004] Therefore, an object of the present inv...
