DYC Electro-Permanent Magnetic Lifters
DYC electro-permanent magnetic lifters: the permanent magnets are switched by a current pulse, so the load stays held when power is lost — no battery backup unit is needed, and electricity is consumed only while magnetizing and demagnetizing. The magnetic circuit is matched to the load: square for blooms and beam blanks, multi-pole for coils and round billets, round for small plates and billets. Range DYC-3030…8282, DYC-350/600, DYC-12439…16039; lifting capacity 3,500–40,000 kg with adjustable holding force.

MW Series Lifting Electromagnet
XINRI lifting electromagnets for different loads.

Shore Power Cable Reel
XINRI shore power drums (cable winches) connect a berthed vessel to the onshore grid: while moored and during cargo handling the ship shuts down its diesel generators, cutting port emissions. The motor-driven winch — drum, motor, reducer, base and control cabinet — pays out and retrieves the cable and stores it when no power is supplied. Mechanical stress in the cable is kept below a set value and cable terminations are relieved of load; on overstretch the shore connection circuit breaker trips quickly, with emergency stop and safety interlocking. High- and low-voltage versions are available.

Electronics
Rectifier Control Cabinets for Lifting Electromagnets
XINRI rectifier cabinets feed lifting electromagnets with direct current from a 3 × 380 V mains. DKX(P) supplies a constant DC 220 V at 30–200 A for MW5-90L…MW5-250L magnets, with short-circuit and overvoltage protection. DQ(K)X adds strong excitation: an elevated voltage for about 5 s at pick-up, then 220 V. DQ(K)XW is a contactless thyristor design for DC 290/220 V with no contactor arcing. DKX-B/BT and DKXBWT-P with a battery bank hold the load during a mains failure (DKXBWT-P for at least 15 min) and provide force adjustment, single-plate release and split control of magnet groups.
