Abstract

The invention provides a balancing device, which comprises a movable counterweight device, a drive mechanism, an induction device and a controller, wherein the movable counterweight device is arranged on a vehicle body, and is provided with a movable counterweight block; the drive mechanism is in drive connection with the movable counterweight block; the induction device is used for measuring the tilting angle of the vehicle body; and the controller is in signal connection with the induction device, judges the tilting direction of the vehicle body according to the tilting angle and controls the drive mechanism to act to drive the movable counterweight block to move towards a direction opposite to the tilting direction of the crane. The invention also discloses the crane with the balancing device. The balancing device provided by the invention can effectively ensure the stability of the crane in a running process and reduce the occurrence of overturning accidents.

Description

technical field [0001] The invention relates to the field of hoisting machinery, in particular to a balancing device and a crane including the balancing device. Background technique [0002] Rough terrain cranes have a higher chassis than truck cranes and can travel with a load. When it is driving with a load, if it encounters uneven ground, the body of the crane shakes seriously, which may even cause the crane to overturn and cause a safety accident of the crane. Contents of the invention [0003] The present invention aims to provide a balancing device and a crane including the balancing device, so as to solve the problem that the cranes in the prior art are prone to overturning accidents. [0004] According to one aspect of the present invention, a balancing device is provided, comprising: a mobile counterweight device, which is arranged on the vehicle body, and has a movable counterweight; a driving mechanism, which is drivingly connected to the mobile counterweight; ...
