Isistimu yokulawula emaphakathi ezimele: isibambo esisodwa singaphakamisa iplathifomu iye phezulu naphansi, idonse imibhoshongo ye-hydraulic emise okwendandatho iqinisekisa ukuzungezisa okungu-360°. Amasilinda aqondile anikeza ukudonsa okunamandla ngaphandle kwamandla engxenye. Ubude obuhlukene bokusebenza (375~1020mm) bufanele opharetha abahlukene.
