About the R 521 E3
The Lukas R 521 E3 is the mid-range telescopic rescue cylinder in the LUKAS e³ family. It delivers the same lifting forces as the compact R 320 (127 kN on piston 1, 60 kN on piston 2) but with a significantly greater reach: extended length of 1,359 mm. This makes it the right tool for dashboard displacement, B-pillar pressing and load-bearing operations where the R 320 falls short.
Piston 1 travels 403 mm, piston 2 travels 377 mm — total stroke of 780 mm. The prismatic claw technology bites into any material surface and resists rotation under load. At 18.2 kg it is compact enough for single-person operation. The e³ dashboard provides full performance feedback. IP 58 rated for fresh and salt water submersion.
