AIl WTB tensioning tools have the capacity to achieve the specified proof load requirements as detailed in EN ISO 898 -1:1999 and ASTM A490m for grade 10.9 Bolts. These feature packed tensioners are fast, safe, reliable, and durable.
It is crucial that the tension stroke of hydraulic tensioners does not exceed maximum piston stroke. In prevention of an overstroke caused by operation error, this tensioner is equipped with a mechanical failure device that locks the piston within the tensioner, therefore preventing high pressure fluid from injuring the operator.
Pressure Cycle Counter For convenient maintenance, all HTS-Aero-WTB tensioners offer a mechanical cyclic counter so the operator can see exactly how many pressurizations the tensioner has performed. |

Swivel movement ensures versatility and smooth operation Due to the very limited space available in many blade compartments, and to better connect multiple tensioners, every HTS-Aero-WTB tensioner can be equipped with a 360° swivel connection. This 360° swivel operation allows the hydraulic hoses to be placed in the best possible position and allow open access to the tensioning tools. | |
High Quality Hydraulic Seals Aero WTB tensioners are fitted with high quality polyurethane, machine cut seals and high strength anti-extrusion rings. The seals are very reliable and can offer thousands of pressure cycles. Seal re-placement is a relatively quick and easy operation. | “Snap-down” Nut Drive To increase tension speed, all HTS-Aero-WTB tensioners are fitted with a spring device that automatically engages the tensioner’s drive socket with the hexagon nut. The operator can see this operation transparently and does not need to waste time on aligning the tensioner with the nut. | ||
High Strength Durable Puller At the heart of all Aero WTB tensioners is the puller, manufactured from high grade aerospace material and carefully designed to provide maximum durability. |
Automatic Tensioner Reset To further improve tension speed, all Aero WTB tensioners are fitted with a spring mechanism that automatically resets the tensioner once the pressure has been released to zero. The tensioner is then automatically ready to tension the next bolt: no operator intervention is required. |
