The active damping movement of the trolley crane consists of a trolley (1) with a suspended load, the suspension system of proof is placed MEMS sensor (2) which is intended to measure the angle of deflection of the load from the rest position. The signals from the MEMS sensor (2) are processed in the control system (8) which in the position of the truck (1), which is determined by the sensor (3) the position and displacement of the load, produces a control signal for the power converter (5). Using a power converter (5) is controlled by the movement of the electric motor (4), followed by trucks (1) of the crane, its movement actively absorbs vibration and displacement of the load. A power converter (5) is supplied from the power supply (6). The stopping of the trolley (1) in the end positions of the arm are concerned limit switches (7) which in the limit positions provided operation of the power converter (5) and the movement of the electric motor (4). |
