Umshini wokugunda we-hydraulic pendulum unesakhiwo esilula, ukusebenza kahle kokugunda, akukho deformation yeshidi ngemva kokugunda, futhi isetshenziswa kabanzi.Umshini wokugunda we-hydraulic wamukela isakhiwo esishiselwe zonke insimbi, eqeda ingcindezi ngokudlidliza, unomshini ozinzile, ukuqina okuhle, impilo ende yomshini, futhi ungasika izinto zokusebenza ezisezingeni eliphezulu, ezingenaburr nezibushelelezi.Lapho usika amashidi ensimbi yobukhulu obuhlukahlukene, kuyadingeka ukulungisa izikhala ezihlukene ze-blade ukuze uqinisekise ukuqina kwama-blades.
