Hydraulic Cylinder with Mechanical Interlock new functional principle large locking forces easy readjustment monitoring of interlocking This hydraulic cylinder has been engineered for functions in which the piston rod and its attached components must be held precisely and safe in their end position, even under the effect of large forces. The mechanical interlock of this Hydropneu cylinder blocks the piston rod with positive locking. Even in the case of a hydraulic pressure drop, safe interlocking is guaranteed. Very high interlocking forces can be realized with this interlocking mechanism. The interlock can be integrated into the front end or rear end position of the piston rod. The compact design of the cylinder compared to conventional interlocking solutions facilitates the implementation of complex forms of construction with elaborate motion sequences. The interlocking mechanism can be integrated into many Hydropneu cylinders. The interlock works automatically as part of the hydraulic impact on the piston or on the side of the piston rod and requires no further control. A major advantage of the Hydropneu solution is the possibility of adjusting the locking position even without any disassembly. It is possible to react to setting characteristics or thermal expansions without having to stop the production for a long time. This cuts down setup time and safes money.

Hydraulic Cylinder with Mechanical Interlock interlocked unlocked Defined sequence of interlocking steps Interlock function independent from installation position Setting of end position without disassembly of components Fields of duties and requirements: Even in the case of a hydraulic breakdown, the mechanical piston rod interlock of HYDROPNEU keeps great loads in their position. Interlock of the piston rod is needed in many areas of hydraulics. In the area of die casting, devices such as gate valves and core puller are regularly interlocked, in order that the mold or the core can’t be...
