Chotsukira mzere umodzi ndichoyeretsa lamba wobwerera. Amagwiritsidwa ntchito kwambiri kutsogolo kwa pulley yokhotakhota kumbuyo ndi kutsogolo kwa chipangizo cholemetsa chowongolera chalamba. Itha kugwiritsidwa ntchito makamaka kuyeretsa gawo lopanda kanthu la lamba wanjira ziwiri. Lili ndi makhalidwe a asidi ndi kukana kwa alkali, retardant flame ndi antistatic, high wear resistance, ndipo siliwononga lamba. Tsambalo limapangidwa ndi polyurethane yamphamvu kwambiri, mawonekedwe owoneka ngati V amatsimikizira ukhondo wa lamba, ndipo kapangidwe kamphamvu yokoka kodziwikiratu kumatsimikizira kubweza-malipiro pomwe tsambalo latha.
