Compact and Space-Saving Design
The compact body design allows LONGLOOD hydraulic bolt tensioners to operate efficiently in restricted or hard-to-reach locations. Despite their smaller size, they generate extremely high tensile force, making them suitable for heavy-duty bolting applications.
High Tension Force Output
Designed to deliver powerful and consistent axial force, LONGLOOD tensioners provide accurate bolt stretching without introducing torsional stress, ensuring more reliable joint assembly and longer fastener service life.
Advanced Multi-Stage Cylinder Design
The innovative multi-stage hydraulic cylinder maximizes the effective tensioning stroke while maintaining a compact footprint. This design reduces the need for repositioning and increases work efficiency during long bolt tensioning operations.
Ultra-High Operating Pressure
- Maximum Working Pressure: 1,500 letsa (150 Mmpa)
- High-strength alloy steel construction
- Precision-machined hydraulic components
- Reliable sealing system for long service life
The ultra-high-pressure design provides exceptional performance for large-diameter and high-strength bolts used in critical industrial equipment.
High Accuracy Bolt Preload
LONGLOOD bolt tensioners apply pure axial force directly to the bolt, eliminating friction-related preload variations commonly found in torque tightening methods.
Benefits include:
- More accurate bolt preload
- Uniform clamping force
- Reduced bolt fatigue
- Improved flange sealing performance
- Increased equipment reliability
Easy and Safe Operation
Designed for single-bolt tensioning applications, LONGLOOD tensioners are simple to install and operate. The ergonomic design reduces operator fatigue while improving productivity and workplace safety.

Advantages of Hydraulic Bolt Tensioning
Compared with conventional torque tightening methods, hydraulic bolt tensioning provides significant advantages.
| Hydraulic Bolt Tensioning | Traditional Torque Tightening |
|---|---|
| Accurate bolt preload | Preload affected by friction |
| Uniform clamping force | Uneven bolt loading |
| No bolt twisting | Bolt experiences torsional stress |
| Faster multi-bolt tightening | More time-consuming |
| Improved joint sealing | Higher leakage risk |
| Longer bolt service life | Greater bolt fatigue |
| Better safety and reliability | Greater risk of preload inconsistency |

Frequently Asked Questions
What is a hydraulic bolt tensioner?
A hydraulic bolt tensioner stretches a bolt by applying direct axial hydraulic force. Once the required preload is achieved, the nut is tightened by hand before hydraulic pressure is released, leaving an accurate and uniform bolt preload without torsional stress.
What are the benefits of hydraulic bolt tensioning?
Hydraulic bolt tensioning provides higher preload accuracy, improved flange sealing, reduced bolt fatigue, faster installation, and greater safety compared to conventional torque tightening.
Which hydraulic pumps can be used?
LONGLOOD hydraulic bolt tensioners are compatible with ultra-high-pressure hand pumps, air-operated hydraulic pumps, and electric hydraulic pumps capable of delivering up to 1,500 letsa.
Which industries use hydraulic bolt tensioners?
They are widely used in oil & gasi, wind energy, offshore engineering, petrochemical processing, power generation, migodi, m'madzi, and heavy industrial maintenance.
