The invention discloses a networked three-dimensional hoisting simulation method based on a B/S (Browser/Server) framework and a cache technology. The method comprises the following steps of: realizing the issuing and Web access of a three-dimensional hoisting simulation system under the B/S framework in combination of the three-dimensional network technology under the B/S framework; entering a hoisting simulation platform, initializing the simulation system and the cache information; establishing a crane model and initializing a hoisting point; adding a hoisted object and an obstacle; carrying out automatic routing in combination with the cache information; and ending the hoisting when a hook reaches the hoisting point and the hoisted object is hoisted. By utilizing the method, the problem that an edition is hard to update, the performance of the system can be improved, the data interaction pressure is released, and thus the in-time simulation of the three-dimensional hoisting system on the network becomes more smoothly.
