Bolted connections are the most commonly used connection systems in mechanics.
Today it is known that of all the different causes of failure (overload, design defects, manufacturing defects and others), improper assembly is the most common.
To ensure the optimal reliability of your bolted joints, it is essential to choose the right preload and find the right way to achieve that preload. The right solution is to tighten the bolts with a hydraulic bolt tensioner Based on its experience in hydraulic tightening, Pilgrim has developed a wide range of hydraulic bolt tensioners, both standard and customer-specific:
- Standard bolt tensioners
- Custom bolt tensioners
- Special bolt tensioners
- Load sensor rings
A standard HYDROCAM® bolt tensioner has a hydraulic body that uses a hydraulic fluid to apply a strong tractive force to the bolt through the bracket screwed onto that bolt. The body also rests on the skirt to exert reaction force on the assembly being tightened.
