Lifting platform for mopeds

Is it possible to design a lift for mopeds that achieves a lift of 75 cm and is lighter and smaller than similar lifts? A team from the technical college in Munich has managed to do just that. As part of a project, they developed a compact model in which numerous standardised parts from norelem were used.

The lifting platform is based on aluminium system profiles that are supported at several points to enable the lifting process to be carried out. A worm gear is driven via the tool holder. The gearbox sets the norelem trapezoidal threaded spindle in a rotating motion, which is then transmitted into an upwards motion, lifting the motorbike upwards. More precisely, the trapezoidal thread nut transmits the force from the spindle to the scissor arm of the lift. The position of the spindle remains stable with the help of a fixed and a floating bearing unit. The elastomer dog coupling compensates for misalignment or slight misalignment between the two shafts by separating the rest of the drive train from the spindle. This protects the drive from damage caused by tension, vibrations and the like.

Furthermore, rubber buffers ensure secure support and serve as an end stop for the worktable. This prevents knocks and bumps on the table. Thanks to the solid rubber tyres, the lifting platform can also be moved and rolled flexibly.
