Bicycle semi-trailer for the last mile of parcel delivery

Congested city centres, hardly any parking spaces and few opportunities to stop for loading and unloading. With delivery vans, you often spend more time in traffic jams than actually making progress. Added to this are low-emission zones, pedestrian zones and traffic-calmed streets. Delivery services, craft businesses and other service providers are facing increasingly serious problems when approaching the last mile. In addition, there are more and more applicants who do not have a driving licence.

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

This assembly is essential for the functionality and safety of the zemmi as it ensures the stability and reliability of the overall design. The bearings have to be low-maintenance and wear-resistant. They must not be impaired by corrosion or contamination and still withstand the highest loads. The ability to function without additional lubricants is vital here to be on the move with as little maintenance as possible while protecting the environment.

Conventional overrun devices are traditionally lubricated, which not only causes high maintenance costs but also has an ecological disadvantage. The lubricants end up in the environment while maintenance costs time, causes unnecessary costs and increases the probability of failure.

To cover the last mile quickly and cost-effectively, more and more cargo bikes are coming into play - especially those that form a bicycle combination and are equipped with a semi-trailer like the zemmi trailer. Bicycles can easily solve the core problems of transporting goods to the end customer: no parking spaces are required as it is possible to stop directly in front of the houses. Also, bikes can enter both low-emission zones and traffic-calmed areas.

In addition, no expensive driving licence is required, which significantly increases the pool of potential and urgently needed applicants. Traffic jams are easily bypassed as bicycle with trailers are allowed to travel not only on roads but also on cycle paths, provided they have a minimum width of 1m.

More flexibility for delivery services, crafts businesses and other service providers - that's the promise of the innovative bicycle semi-trailer from zemmi. With its impressive loading volume, it offers plenty of storage space, and with a maximum payload of 450kg, up to 300 parcels 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 was optimally implemented with iglidur J plain bearings. They meet all the desired requirements: They are maintenance-free, work reliably without lubricants and easily cope with the high loads caused by weather and mechanical forces. The iglidur bearings are a durable and environmentally friendly alternative to conventional solutions and make a significant contribution to the sustainability of the entire system.
