In view of the intelligent construction equipment of installing slabstone for highrise buildings，aerial work platform is the basis of the intelligent construction equipment such as robot. In the actual construction of installing slabstone, inertia caused by motion of the slabstone installation robot, wind load and other factors will cause vibration of aerial work platform. The reason of vibration for aerial work basket most widely used in construction was analyzed detailedly. The vibration model of platform was established and dynamics simulation was carried out by ANSYS. So that the correctness of analysis of vibration causes was verified. Which will provide a theoretical basis for restraining vibration of the aerial work basket.
