Ka karangahia ano e Hydraulic Grapple te Hydraulic Grapple me te whakatuwhera me te kati te hanganga, i te nuinga o te waa ka peia e te rango waipēhi, i tito mai i te tini o te kauae pereti hopu waipēhi ka kiia hoki ko Hydraulic claw. Kei te whakamahia nuitia te hopu hydraulic i roto i nga taputapu motuhake hydraulic, penei i te keri hydraulic, hydraulic crane me etahi atu. Ko te waiu Pressure hopu he hua hanga waipēhi, i tito i te rango waipēhi, peere (pereti kauae), pou hono, peere taringa pereti, ngutu taringa peere, niho peere, nohoanga niho me etahi atu waahanga, no reira ko te whakahiato te tino mahi whakaputa o te waipēhi. kapohia, ka pa tika te kounga o te raima ki te kaha o te hanganga o te hopu waipēhi me te oranga o te peere. I tua atu, ko te cylinder hydraulic te waahanga taraiwa tino nui. Ko te hopu Hydraulic he ahumahi motuhake nga waahanga mokowhiti, he taputapu motuhake e hiahiatia ana kia pai ai te mahi me te kounga teitei
