TENSIONERS

A robust portfolio of hydraulic bolt tensioners engineered for accurate, simultaneous bolt loading in critical joint applications. Designed to apply precise axial load across defined minimum–maximum tension ranges, these systems eliminate torque-related inconsistencies and ensure uniform clamping force. Suitable for demanding industrial environments, hydraulic bolt tensioners are widely used where joint integrity, safety, and repeatability are paramount.

Standard

The ABS standard range bolt tensioners embody versatility and dependability, serving as hydraulic tensioners well-suited for a wide spectrum of bolting applications. Their optimisation for top-side operations makes them particularly fitting for tightening ANSI, ASME, and API flanges.

Multistage

The ABS multi-stage bolt tensioners offer versatility and dependability, serving as hydraulic bolt tensioners well-matched for demanding high-load and confined-space applications. Tailored for utilisation on wind turbines, this multi-stage hydraulic bolt tensioner is crafted to endure extended usage while requiring minimal maintenance.

Direct Fit

When space is tight and loads are heavy, the ABS direct-fit hydraulic tensioners step up to conquer the challenge. This ingenious one-piece design delivers a perfect fit for confined environments, eliminating the need for bulky adapters and simplifying setup.

Hydraulic Nuts

ABS hydraulic nuts revolutionize large bolt tensioning, offering a safe, efficient, and precise solution. This nut features an internal jack with an external locking collar. Pressure creates a gap between the nut and collar due to joint compression, gasket presence (if applicable), and bolt elongation.

Tensioning Pumps and Hoses

Tensioning pumps, also known as hydraulic tensioning pumps, are widely used in various industries to apply specific tensioning forces to nuts, bolts, and other fasteners. These pumps are typically used in conjunction with hydraulic tensioners. By applying hydraulic pressure to the tensioner, the pump facilitates the even distribution of load on the bolts. Tensioning pumps are available in different configurations, including hydraulic, pneumatic, and electric models, allowing for flexibility in matching specific application requirements, such as desired tensioning force and available power source.
