Multi-stage hydraulic bolt tensioner

Multi-stage hydraulic bolt tensioner

The CTP-M series multi-stage hydraulic bolt tensioners feature a central tie rod with two load cells, a construction that allows the load capacity to be doubled while keeping the external cell diameter unchanged.

The result is an extremely compact solution with the same supplied load, especially suitable for applications where space around the nut or flange is restricted.

Key Features

• Multi-stage design: Two load cells act on a central tie rod, increasing load capacity without increasing the external dimensions of the cell.
• Compact solution: Provides very tight clearances while maintaining equal supplied load, making it ideal where radial width is restricted.
• Fast-operation version: Hydraulic tensioners are also available with a gear nut rotation mechanism to speed up tensioning operations.
• Custom bridge: The bridge can be shaped to best adapt to the space available between the nuts and the installation constraints.
• Customer-specific design: F.P.T. designs and manufactures hydraulic bolt tensioners to customer requirements after a preliminary study of the existing dimensions.
• Applications: Used for controlled tightening of nuts on stud bolts in marine engines, large valves, compressors, pumps, presses, large machine tools and turbines.
