Kwimisebenzi ye-shift enye okanye izicelo ze-continuous-duty eziphezulu, utyalo-mali lwe-VSD kunzima ukuluthethelela kwaye lusenokungaze lubuyisele. Indawo ephakathi ixhomekeke kumaxabiso ombane wasekhaya, ukusebenza kakuhle kwepompo ekhoyo, kunye nokunyamezela komqhubi kwiiprojekthi ezinkulu ezinembuyekezo yeminyaka emininzi.

Kubathengi abalungele ukuqhuba uhlalutyo kufakelo oluthile, iqela lethu lobunjineli linokujonga idatha yomjikelo womsebenzi kwaye libonelele ngovavanyo lokufaneleka kwe-VSD. Thumela iirekhodi zoxinzelelo kunye nokuhamba kwamanzi ezibanjiweyo ngokusebenzisaiphepha loqhagamshelwanokwaye siza kuqhuba ubalo ngokuthelekisa amaxabiso angoku e-VSD kunye namaxabiso aqhelekileyo ombane wemizi-mveliso. Uvavanyo ludla ngokuthatha iintsuku ezimbalwa kwaye lunika abathengi idatha abayidingayo ukuze benze isigqibo sotyalo-mali olunolwazi.

Iinkcukacha zobugcisa kunye nesikhokelo sokukhetha iimpompo kunye neenkqubo ze-servo ezichazwe kweli nqaku ziyafumaneka kwi-intanethi yethu.iziko lokukhuphelaKubathengi abathelekisa i-VSD retrofit ngokuchasene nokutshintshwa kwenkqubo ye-servo hydraulic epheleleyo, iziko lokukhuphela likwabandakanya idatha yokuthelekisa kunye nezifundo zeemeko zesicelo.
