Horizontal Back (HB) and Horizontal Side (HS) -models offer different layout for standard machines. Different layouts provide optimal crimping head position for different applications.
 
HB-model is optimal for small but heavy products which can be fed below with hydraulic jack or from top with manipulator.
 
HS-model is ideal when crimping head position needs to be as low as possible. For example feeding long tubes and pipes via feeding rail.
