In addition to the coupling change system with the code no. 620 167, this additional change plate offers the possibility to switch quickly and easily between different coupling types. Depending on the application requirements, the desired four-hole coupling type can be attached to the exchange plate. The four-hole adapter of the interchangeable plate is suitable for couplings with a hole pattern of 83 x 56 mm. With the interchangeable plate, you are able to exchange between pin or ball couplings as required on your interchange system without additional assembly.
