Zintathu iindidi ze-hydraulic thumb: i-weld enyukayo kuhlobo, uhlobo lwe-pin engundoqo, kunye nohlobo lwekhonkco oluqhubekayo.Uhlobo lwekhonkco oluqhubela phambili lwe-hydraulic ubhontsi lunoluhlu lokusebenza olusebenzayo olungcono kunohlobo lwe-pin oluphambili, ngelixa uhlobo lwe-pin oluphambili lungcono kune-weld enyukayo kuhlobo.Ngokubhekiselele ekusebenzeni kweendleko, uhlobo oluphambili lwepini kunye ne-weld yokunyuka kuhlobo lungcono kakhulu, olubenza badume kakhulu kwiimarike.KwiMisebenzi yezandla, ububanzi kunye nobungakanani bemichilo yobhontsi bunokwenziwa ngokwemfuno yakho.
