The invention discloses a dual-winding synchronous control system and a dual-winding synchronous control method for a crane. The system comprises two laser distance measuring instruments which are symmetrically arranged at the two sides of a crane boom head, wherein a probe of each laser distance measuring instrument is kept vertically downward; the crane boom head is connected with a hanger below through two groups of independent speed-adjustable windings; distance measuring baffle plates extend out from the two sides of the hanger; each distance measuring baffle plate is positioned below the laser distance measuring instrument at the corresponding side; the two laser distance measuring instruments are respectively used for measuring height from the winding at the corresponding side to the distance measuring baffle plate at the side and transmitting a height signal to a controller; the controller is used for controlling the speed of the corresponding winding through a winding speed regulating mechanism. Through the laser distance measuring instruments at the two sides of head of a cantilever crane, height difference between pulleys at the two sides of hanger is obtained; by regulating the rotation speed of the windings, the height difference is reduced to guarantee that the dual windings are synchronous, so that the stability problem and the safety problem of dual-winding synchronous operation can be solved, the control is simple and reliable, and the application prospect is good.
