AC Variable Frequency Drive Drawworks
• Zvikamu zvikuru zvekudhirowa ndeye AC variable frequency mota, gear reducer, hydraulic disc brake, winch frame, drum shaft assembly uye automatic driller etc, ine high gear transmission performance.
• Iyo giya ioiri yakaonda yakazorwa.
• Dhirowa ndeyekurongeka kwedhiramu shaft uye dhiramu rakaiswa mumitsetse. Kuenzaniswa nemadhirowa akafanana, ndeyezvakawanda zvakanaka, senge chimiro chakareruka, vhoriyamu diki, uye huremu huremu.
• Ndiyo AC siyana frequency mota chidhiraivho uye stepless kumhanya murau mukosi yose, ine simba guru uye yakafara kumhanya chinjika siyana.
• Iyo huru bhureki inotora hydraulic disc brake, uye bhureki disc imvura kana mweya wakatonhodzwa.
• Mabhureki ekubatsira ndeemotor dynamic braking.
• Akashongedzerwa yakazvimirira injini otomatiki chibooreso hurongwa.
