Description

technical field [0001] The invention relates to the technical field of cranes, in particular to a device and method for monitoring the running position and posture of large and small vehicles of bridge and gantry cranes. Background technique [0002] Cranes are widely used in material handling in various industries and play a very important role in national economic construction. Hoisting machinery is an important part of special equipment, accounting for more than 22% of all 8 categories of special equipment. Product quality and safe production are related to people's life safety. Effective monitoring of the crane's operating range is conducive to avoiding collisions between the operating crane and equipment, plant buildings, and operating cranes, and improving the safe production of the crane. [0003] According to the control mode, the existing gantry cranes can be divided into: programmable controller mode and master controller mode. Cranes controlled by programmable c...
