Measuring the rubber track for a mini excavator is a relatively easy process. Below you will find a file with our brief instruction, which will help you find the right rubber chains for your machine. Everything, which you need, is a measuring device (tape measure, caliper or line). This procedure is mandatory, in case you do not know the exact make and model of your excavator and do not find any prints on the old chains. In any case, we are available if you need further assistance. EFIR RVM not only offers quality spare parts for construction and mining machinery, but also the necessary consultation when purchasing them. https://efir-rvm.com/wp-content/uploads/2023/04/instruktsia-kak-da-izmerim-gumena-veriga-EFIR-RVM-USCO-ITR.pdf
