The scissor lift PB S171-12ES with a working height of 17.10 m differs from the S171-12E by the support system which offers up to 200 mm level compensation. With just the push of a button, the machine levels automatically within a few seconds. This allows an exactly vertical or parallel stroke to the object with optimum stability. However, the ES series can also be used without a support, ie like a “normal” scissor lift and can therefore be moved in full (like all PB models).
