Abstract
Conventional trolleys work well on flat surfaces but fail on staircases. Specialised climbing mechanisms allow a cart to ascend and descend steps while carrying moderate loads, reducing physical strain on workers in warehouses, hospitals, residential buildings and small industries.
This project develops a Staircase Climbing Trolley. A frame supports a load platform and a climbing assembly (typically tri-star wheels, planetary wheels or a short track). As the trolley is pulled or pushed onto a step, the wheel cluster rotates or the track engages, lifting the frame onto the next tread. Key aspects include kinematic design of the climbing unit, structural fabrication, balance and ergonomics. The unit demonstrates practical material handling and mechanism design suitable for academic evaluation.
It is an excellent final-year project for Mechanical, Production and Mechatronics Engineering students, combining fabrication, kinematics and real-world material-handling applications.
