Podpira protokole, kot so Modbus in Profibus DP, in se lahko neposredno poveže na stare sisteme brez velikih sprememb. Vstavitev in uporaba, hitro raziskovanje napak, preprosta vzdrževanje, preprosto nadgradnja rudarske opreme, varčevanje denarja in zmanjševanje skrbi.
To mora biti! Posebno oblikovan za podzemno vzelce, samodejno utišuje nihanje blaga. Včasih prilagaja hitrost med dvigom, brez nihanja ali trepetanja, da se izogne poškodbe blaga ali osebja, varno in učinkovito, kar omogoča bolj zanesljive rudarske operacije.
IP00 oblika, vendar z zaščito pred pršavljenjem in korozijo, 3M5 standardni seizmični standard lahko izdrži rudarske vibracije. Opričen z notranjim C3 filterjem, zmanjšuje harmonično motnjo in ni strahu pred težkim pršavljenjem. Oprema deluje stabilno, kar rudarjem zagotavlja večjo varnost pri uporabi.
