Elevator based on brake mechanism

The utility model belongs to the technical field of elevators, particularly relates to an elevator based on a brake mechanism, and aims to solve the problems that the bottom of an existing elevator is difficult to be stably fixed on the ground, the operation risk of workers is increased, and a conventional screw type fixing support leg needs to be frequently and manually screwed by the workers to be fixed during use, so that the working efficiency is high. According to the technical scheme, the lifting device comprises a lifting device body which is arranged at the top of a base and has a lifting function, and a platform which is used for bearing goods is arranged at the top of the lifting device body. When the lifting device is used, the gravity center of equipment is lowered, the contact area between the equipment and the ground is increased, the friction force between the equipment and the ground is increased, and the bottom of the lifter is stably fixed on the ground, so that the safety of a worker during
