High-pressure bolt tensioning system (electrically driven)

Electric Bolt Tensioning Systems

The electric bolt tensioning systems from GLOBE are designed for users who require maximum control, accuracy and ease of use when preloading bolted connections. Unlike air-driven systems, these units operate fully electrically, providing more stable pressure build-up, reduced noise and higher efficiency—ideal for industrial environments or locations without a compressed air supply.

Electric bolt tensioning uses high-pressure oil to hydraulically stretch the bolt. By applying controlled pressure, space is created between the nut and the bolt, allowing the nut to be tightened manually while the system remains pressurised. After releasing the pressure, a highly accurate, safe and durable connection is formed between the bolt and nut—even under extreme conditions.

GLOBE’s electric tensioning systems are engineered with a strong focus on safety and reliability. They are delivered as complete units, easy to operate, and compliant with all requirements for professional bolt tensioning applications. In addition, they offer consistent performance and minimal maintenance requirements, making them ideal for both field use and workshop environments.
