BLS-series, stage-lift cylinders

A Simple Solution to Higher Lifting Jobs

  • Double-acting cylinder with solid plunger design
  • PLC-controlled synchronized stage-lifting
  • Lifting capacities from 10 to 1,000 ton per lifting point
  • Double-acting jacks with solid plunger: RAR, RR and CLRG-series
  • Double-acting hollow plunger jacks RRH-series

Stage-lift sequence Lift & Crib System:
1. stage-lift cylinder with retracted plunger is placed on solid support under load.
2. plunger extends, lifting load, giving clearance to insert two outer cribbing blocks under the spreading plate.
3. plunger retracts, giving clearance to insert central cribbing blocks which will support plunger plate for next extension.
4. plunger extends, lifting the load, giving clearance to insert two new cribbing blocks, placed crosswise under spreading plate.
