PSD two stage The two stage hydraulic tensioner PSD enables screw joint assembly and disassembly without torsional stress for the bolt. The pre-tensioning power is precisely adjustable. 61 Hydraulic Tensioners Automatic piston return Swift operation: The puller is automatically returned to its original position once the pressure has been released. Cycle counter The cycle counter indicates number of cycles performed and will consequently indicate the maximum cycle service point, thus avoiding damage and failures via preventive maintenance. Stroke limiter – mechanical Ultimate safety: The mechanical end stop prevents the over extension of the piston (even under maximum load). Free Rotating Bridge Exceptional handling: Straightforward alignment, independent of the bolt configuration. Gearbox Unique ease of use: The nut can be turned swiftly and with perfect ease using a ratchet or a torque wrench that is driven by a gear drive (maximum input torque: < M36=40 Nm, > M36=80 Nm). Rotating socket – spring-loaded Prevention of installation damage during the positioning of the tensioner: The spring affords the rotating socket axial flexibility. Stainless steel handle Safety: Protection of the hose couplings against damage. Optimal grip and dexterity provided by the detachable handle of the tensioner. Safety indicator – green (optional) Safe controlled operation: Verification of sufficient engagement of the bolt/stud. Maximum stroke indicator Optical safety: Visual indication of maximum stroke (max distance piston can move out of the tensioner body). Supporting surface – optimized Outstanding versatility in any environment:The tensioner is especially well suited for use in tight spaces thanks to its optimal shape.
