Bolting Technology and Torque Wrenches

Torque wrenches are used wherever screw connections need to be tightened precisely, securely, and consistently. In industrial applications, the energy and plant engineering sectors, or on production lines, precise torque control is crucial for quality, safety, and process stability.

PLARAD offers a wide range of torque wrenches for various applications – from compact cordless torque wrenches for flexible use to high-performance hydraulic torque wrenches for very high torque values. The various models differ in terms of drive type, power range, precision, and typical applications.

Below is an overview of the different types of torque wrenches and their respective applications to help you find the right solution for your needs.

Cordless Torque Wrench

Cordless torque wrenches are particularly well-suited for mobile applications and work sites without a fixed power supply. They combine high flexibility with precise torque control and are ideal for assembly and maintenance work at various locations. Thanks to their cordless operation, cordless torque wrenches enable ergonomic work, especially during maintenance tasks or when working on hard-to-reach fasteners. Modern battery systems provide consistent performance and reliable repeatability.

Electric Torque Wrenches

Electric torque wrenches are the right choice for applications with high demands on accuracy, process reliability, and documentation. They are frequently used on industrial production lines, where controlled and traceable fastening operations are required. Thanks to precise control and regulation technology, torque and rotation angle can be monitored accurately. Electric torque wrenches deliver repeatable results and can be easily integrated into automated or semi-automated manufacturing processes.

Pneumatic Torque Wrenches

Pneumatic torque wrenches are characterized by their robust construction and high durability. They are particularly well-suited for industrial environments where compressed air is already available and reliable fastening technology is required. These wrenches offer an excellent power-to-weight ratio and are ideal for repetitive fastening tasks involving medium torque levels, where speed and durability are key.

Hydraulic Torque Wrenches

Hydraulic torque wrenches are used wherever very high torques are required – for example, in the plant engineering, steel, or energy sectors. They offer maximum power combined with high precision and safety. Thanks to their hydraulic drive, even large bolted joints can be tightened or loosened in a controlled and uniform manner. Hydraulic torque wrenches are particularly well-suited for critical bolted joints where exact torque values are absolutely essential, even in confined or difficult-to-access spaces.

Tensioner

Tensioners are not torque wrenches in the strict sense, but they play an important role in fastening technology and industrial clamping processes. They are used to clamp, secure, or preload components in a controlled manner – often in combination with hydraulic systems. In industrial applications, tensioners ensure uniform force distribution and high process reliability, for example during assembly, testing, or manufacturing processes. They complement torque wrenches in situations where precise preload forces are required in addition to fastening.

Manual Torque Wrenches

Manual torque wrenches are used when screw connections need to be tightened or loosened precisely without an external power source. They are particularly well-suited for maintenance work, small-scale assembly tasks, or locations where electrical or hydraulic systems are not available or not necessary. Thanks to their ease of use and robust construction, manual torque wrenches enable controlled force transmission and are ideal for applications involving low to medium torque levels, where cost-effectiveness and flexibility are paramount.

Hydraulic Power Packs

Hydraulic power packs serve as the power source for hydraulic torque wrenches and tensioners. They generate the hydraulic pressure required to deliver very high forces precisely, evenly, and in a controlled manner, making them a central component of high-performance tightening systems. Depending on the configuration, hydraulic power packs also perform control, monitoring, and documentation functions. In addition to precise pressure and torque control, certain models also enable rotation angle monitoring and the documentation of fastening data. This makes them particularly suitable for applications with high requirements for process reliability, traceability, and quality assurance. Hydraulic power packs are available for both stationary and mobile applications and can be flexibly adapted to different tools, torque ranges, and industrial scenarios.
