Custom made hydraulic bolt tensioners
For the tensioning of the tie rods for the assembly of a machine part which is part of a rolling mill FPT – Fluid Power Technology has created two special made hydraulic bolt tensioners operated by a pneumohydraulic pump model PP1500G.
The two hydraulic bolt tensioners have been designed and produced according to customer specifications; are M120x6 double stage spring return, 1500 bar 6980 kN and have a stroke of 15 mm.
The bolt tensioners have been designed with the rotation of the hydraulic cell independent of the reaction bell and have a nut-tie coupling with anti-rotation device.
FPT – Fluid Power Technology designs and manufactures standard and hydraulic bolt tensioners following customers need from 700 to 2500 bar.
The TTS series is the standard range and is designed to adapt to the main types of flanges. The reference markets increasingly require custom hydraulic bolt tensioners made to customer specifications in order to be able to operate in the required dimensions and with the characteristics suitable for individual needs. The special version can be compact, multi-stage, with threaded insert and with spring return. The CTP series with threaded insert is characterized by having the interchangeable threaded bush which allows to operate on tie rods with different threads with a single hydraulic cell. The CTP-M series are characterized by having a central tie-rod on which two load cells act, this type of construction allows to double the load capacity while maintaining the outer diameter of the cell identical. The result obtained is extremely compact with the same load supplied. The CTP-C series is the compact version with threaded piston. This constructive typology allows to reduce the overall dimensions allowing to operate in environments with reduced spaces.
