Multi-stage hydraulic tensioners
The CTP-M series is the line of hydraulic bolt tensioners characterised by a central puller with two loading cells operate on, this construction makes it possible to double the load capacity whilst keeping the external cell dimension the same.
The results obtained are very tight clearances with the load supplied remaining equal.
• this type of bolt tensioners are suitable for all uses where radial width is restricted.
• Hydraulic tensioners are also available in the version with gear nut rotation mechanism to speed up the tensioning operations.
• Bridge can be moulded in order to best adapt it to the space available between each nut.
FPT can design and manufacture this type of hydraulic bolt tensioners on the customer requirements.
