Design of Stairlift for Curved Path and mechanism

India still finds it challenging to install these systems in most building structures as many of these structures are old structures & have their limitations for installing elevators & escalators. The project is to counter the social problem faced by the different classes of people for mobility on staircases of many indoor & outdoor structures.

To overcome all these factors, the stairlift concept came, which reduced extra costing associated with the lift mechanism. Stairlifts Bristol provider Pearce Bros Stairlift this topic deals with the designing and manufacturing a stairlift, which can be used as a human transportation system. A chair or carriage has attached to the rail. A person on the chair or carriage has lifted as the chair or carriage moves along the fence. It should also be used to carry goods across the staircase.

The stairlift is a type of conveyance that can be mounted on the staircase without altering the civil structure. We use a DC motor for the forward and reverse motion of stairlift with toggle switches and push-buttons in this system. Stairlifts come in various types depending upon placement, type of stairs, and method alighting. In these, the straight stairlift is the most popular, widely used throughout the world. Curved Stairlifts have been used if the staircase inside the house has curves.

Stairlifts maintenance and remanufacture

The Use of remanufacturing engineering is related to the design method of stairlift used over here. By applying the remanufacturing strategy at the end of the product lifecycle, the enterprise can reduce costs and improve the lifecycle, and the enterprise can reduce costs and enhance competitiveness. Suppose the remanufacturing process has not been considered when a product is being designed. In that case, it will be challenging to remanufacture the things at the end of its lifecycle, as some of the elements and parts could have been poorly worn, resulting in a product that cannot be remanufactured. Therefore, it is need to consider the remanufacturing characteristics during the product design phase, facilitate product reuse, upgrade, and maintenance, and make it easier to disassemble and recover. This paper mainly focuses on the flexible belt drives used in engineering applications & systems.

Problem Statement

To design a stairlift that is useful for lifting up and many up sand down the stairs in desired time who can find it difficult in doing so themselves with the help of an optimized driving mechanism for the curved track, ensuring complete safety of the passenger.


  • Selection of optimized tranferral mechanism by testing on the actual test model.
  • We are integrating design assembly into the product design stage.
  • Design CAD models
  • Analyses of stairlift models.

To compare analysis and logical results to ensure a safe design model. Selection of Optimized Mechanism For the efficient, optimum, and safe Stairlift performance, choosing the correct driving mechanism is the key. Stairlift manufacturers worldwide use different types of driving means depending upon the nature of stairs, load-carrying capacity, and comfort of the user. The use of a PMDC motor makes the method compact. It is lighter in weight and offers high torque at a lower velocity. For the driving mechanism, rack and pinion would be an appropriate mechanism because of its smooth operation, and it can take smooth turns around curves.
