Bicycle semi-trailer for the last mile of parcel delivery

Overcrowded city centres, hardly any parking spaces and few opportunities to stop for loading and unloading. Delivery vans are often stuck in traffic jams rather than making progress. Added to this are environmental zones, pedestrian zones and traffic-calmed streets. Delivery services, craft businesses and other service providers are facing ever greater problems when travelling the last mile. In addition, there are more and more applicants who do not have a driving licence.

To overcome these problems, zemmi has developed an innovative bicycle semi-trailer. This has a special overrun device including a bearing point. This device was developed in combination with the fifth wheel coupling and is currently being patented. It has to withstand the high forces that occur when starting off and braking.

This assembly is crucial for the functionality and safety of the zemmi, as it ensures the stability and reliability of the overall structure. The bearings must be low-maintenance and wear-resistant. They must not be affected by corrosion or dirt and must still be able to withstand the highest loads. The ability to function without additional lubricants is of central importance here in order to be as low-maintenance and environmentally friendly as possible when travelling.

Conventional overrun devices are traditionally lubricated, which not only results in high maintenance costs, but is also detrimental to the environment. The lubricants end up in the environment and the maintenance intervals prolongs the time wasted, causing unnecessary costs and increasing the probability of failure.

More and more cargo bikes are being used to cover the last mile quickly and cost-effectively - especially those that form a bicycle combination and, like the zemmi trailer, are equipped with a semi-trailer. The core problems of logistics up to the end customer can be easily solved with bicycles. No car parks are required, as parking is possible directly in front of the houses. Bicycles can be used in low emission zones as well as traffic-calmed areas.

In addition, no expensive driving licence is required, which significantly increases the number of potential and urgently needed applicants. Traffic jams can also be easily avoided, as bicycle combinations with trailers are not only allowed to ride on roads, but also on cycle paths as long as they are at least one metre wide.

More flexibility for delivery services, craft businesses and other service providers - that's the promise of the innovative bicycle semi-trailer from zemmi. With its impressive load volume, it offers plenty of storage space, with a maximum payload of 450kg, up to 300 parcels can fit on the loading area, which is also suitable for pallets.

The innovation of the zemmi bicycle semi-trailer is a new development of the overrun device, which could be optimally realised with iglidur J plain bearings. These bearings can fulfil all desired requirements. They are maintenance-free, work reliably without lubricants and can easily cope with the high loads caused by weather and mechanical forces. The iglidur bearings offer a durable and environmentally friendly alternative to conventional solutions and make a decisive contribution to the sustainability of the overall system.
