Hydraulic tyre doubling / unpacking machine COT‑31

The COT-31 hydraulic tyre doubling/unpacking machine (tyre doubler) is ideal for companies exporting scrap or used tyres. It is used to double or triple tyres (pack them one inside the other up to a maximum of 3 in a pack), thus significantly reducing the cost of transporting them. It also has a tyre unpacking function, but this is very limited (unpacking packs of more than 3 tyres requires a tyre unpacker).

Thanks to its small dimensions and ability to be disassembled (making it even more portable than the COT-2), it is ideal for moving from place to place and does not take up too much space. It can have either a 230V or 110V motor, depending on the customer’s order, making it suitable for use worldwide.

We are the original inventor of this type of machine and we patented it. Similar machines on the market are cheap knockoffs of this model and they break down quickly while our machines are very durable and they can work for many years even without proper maintenance.
