Yueyang Cod Technology Co., Ltd. specializes in producing permanent lifting, YC1 series permanent lifting, (a small plate for suction lift materials and processed parts, lifting without having to grip tools, lifting the object was not hurt surface. suction surface using V-groove design, both suction hanging flat objects, but also suction hanging rod, steel pipe.'s unique circuit design, turning the handle to achieve suction discharge and discharge. lifter suction state suction surface is magnetic, the discharge state of the suction side jack is not magnetic. safety factor of 3.5 times.) YC2 series permanent lifting, (suitable for handling large steel plates, steel plates of irregular shape, heavy forgings and castings. unique design of magnetic circuit and the discharging institution, through the main hook of the lift control switch state circuit jack. circuit in the "off" state, not of external magnetic lifter, to discharge state; circuit is "open" state lifting device when the suction surface for the magnetic performance, as the suction state. The series can be selected electrically controlled magnetic lifting device on and off states, ordering please specify "electric." safety factor of 3.5 times.) YX2 Series permanent lifting, (for lifting large steel plate. through the main hook of the jack lifting the automatic control of suction, discharge, no manual)) YQ3 series permanent lifting (for handling small and medium sized sheet. Manual Cam discharge. structure is simple, easy to operate)
