In order to improve safety

comfort and reliability of mine elevator in the process of operation

the trajectory planning of mine elevator’s overlap platform is carried out.The self-locking overlap platform which includes straight line mechanism and turnover mechanism is designed

and according to the require of rotary angle of the footboard

the parametric equation of constraint point of the footboard is established.By analyzing the radius of curvature under different parameters

the suitable curve of landing overlap platform is gotten.In order to verify the stationarity

the simulation models of landing overlap platform based on ADAMS is built.The result of motion simulation shows that the curve of velocity and acceleration of the constraint point are consistent with the theory model.The movement platform of platform is reposefully and reliably

some reference can be offered for designing platform mine elevator.
