Abstract: In order to meet the overhaul requirements of hydraulic hoist for hydraulic engineering, a visualization system for simulation training is developed using 3D modeling and virtual interactive simulation technology. The 3ds Max software is used to simulate the general knowledge of maintenance, main equipment and auxiliary equipment of hydraulic hoist. The virtual simulation system is developed corresponding to the real hydraulic hoist. The system is used to conduct virtual interactive training for employees about operation method of maintenance equipment, maintenance process and accident handling, and the simulation test module is used to verify the training effect. This system is a classic combination of modern computer simulation technology and traditional hydraulic equipment.
