Lower parts first, inside out, light parts to heavy parts. These are the rough rules on which the assembly sequence is based.
Whereas in the classic construction methods used by established vehicle manufacturers, a body colored in an immersion paint bath is usually filled with components afterwards, the multi-part frame structure of the TWIKE 5 allows it to be built up in layers.
The layered construction (lower parts first) on a height-adjustable working platform, thus enables a time-saving and ergonomic workflow.
The pre-assembly of sub-assemblies gives the opportunity to carry out small-scale work processes close to the body and to sort these assemblies, taking into account accessibility in the final assembly (from the inside to the outside).
An overhead crane on a trolley, aligned with the position of the working platform, helps the worker to bring the assemblies into the desired position in a way that is gentle on the body and precise.
After just the third stage of final assembly, more than 50% of all vehicle components will have been joined, providing a solid basis for the bodywork, which takes less than eight hours.
For a small series, this tight assembly time is ambitious, but possible according to our assessment and comparison with empirical values from the assembly of the TWIKE 3.
One challenge to be mastered remains the optimization of all upstream assembly processes while simultaneously meeting all quality requirements.
