These machines have a distinctive hydraulic cylinder with the handle being attached to the piston of the hydraulic system.  The other end of the piston is attached to the one of the folding dies. For this machine, the hand or foot pedaling provides the force which is amplified by the hydraulic systems and these results to faster pipe and tube bending.  Using this machine, the operator can bend large diameter pipes. The use of hydraulic system enable easy bending of pipes and this machine can be used in small manufacturing environment with moderate number of pipes to bend.
