MINIMUM RETRACTED HEIGHT FOR SMALL INSERTION OPENING The LUKAS rescue rams not only impress with a convincing lifting power, a particularly firm grip thanks to the "claw geometry" and a particularly long stroke, they can also be used flexibly. For example, our telescopic rescue cylinders are available in three different lengths, which can be used as required. The R 520 eWXT has a minimum retracted height and can therefore be used with even the smallest insertion opening. Its claw technology bites into any material and in any position. The small giant is waterproof like the entire eWXT range and is equipped with a 5 Ah or 9 Ah rescue battery. The 9 Ah battery offers the longest operating time in the industry.
