What testing machines do you recommend for on-site tests?

If you want to test anchors on-site you need especial testing machine. Basically, there are 3 suppliers in the market with different solutions:

HYDRAJAWS

They have several models for different purposes. For anchors we do recommend:

M2000 PRO: for medium loads

• Detachable 25 kN Dual Scale Digital Gauge.
• Up to 50mm stroke.
• 2020 Load spreading bridge with adjustable telescopic legs and swivel feet.
• Bolt tester adaptor with M12 locking adaptor.
• Turning handle with 22 mm integrated nut (for use in confined spaces).
• Six threaded button adaptors (M4, M5, M6, M8, M10, M12).
• Six slotted button adaptors (4.5, 5.5, 6.5, 8.5, 10.5, 12.5).
• M12 ringbolt adaptor clevis.
• M16 & M20 thread stud adaptors.
• Calibration certificate (valid for 12 months).
• Robust carry case.
• Compatible with Hydrajaws Bluetooth Digital System.

M2050PRO: for high loads

• Up to 50 KN.
• Up to 50 mm of stroke.
• Detachable 50 kN dual scale digital gauge.
• 2050 Spreading Bridge with telescopic legs and hardened pins.
• Turning Handle with integral 24mm nut.
• M12 Locking Adaptor.
• M12 Ringbolt Adaptor Clevis.
• Bolt Tester Adaptor.
• Threaded stud adaptors: M16, M20 and M24.
• Button Adaptors: M10, M12 Threaded, and 6.5, 8.5, 10.5, 12.5 slotted.
• Hydrajaws calibration certificate.
• Robust carry case with grab handle.
• Compatible with Hydrajaws Bluetooth Digital System.

M2008: for heavy duty loads

• Up to 145 kN.
• Lightweight (8.5kg).
• Compact and Portable.
• Aluminium off set triangular load spreading bridge with steel ball pins.
• Ease to adjust telescopic aluminium legs.
• Ratchet handle operation.
• Low handle effort to achieve load.
• Threaded adaptors available in sizes: M20>M12, M20>M16, M20>M20, M20>M24 & M20>M30.
• Equivalent UNC Imperial Threaded Stud Adaptors available.
• 0-145kN Dual Scale Digital Gauge.
• Hydrajaws calibration certificate (valid for 12 months).
• Robust carry case with telescopic handle and wheels.

The Hydrajaws Bluetooth Digital system allows on-site pull tests to be automatically recorded and compiled into a digital report using the Hydrajaws Bluetooth Digital App on a mobile phone or tablet device. These reports can be sent directly to clients or managers and are stored in the cloud to be accessed remotely anywhere on a browser in a user own company dashboard.

There are other models for scaffoldings, safety lifelines, wall ties, etc.

DYNATEST

They have several models for different purposes. For anchors we do recommend:

DTEpico-VCH 2500: for medium loads

• Up to 25 kN.
• Simple and quick setting up.
• Reading on a digital indicator, pressure sensor with peak value. The indicator operated with one 3 volt battery (type CR2430), stopping automatically after 15 min.
• Packed in a transport case (with a set of optional accesories).

DTEpico-VCH 5000: for high loads

• Up to 50 kN.
• Simple and quick setting up.
• Reading on a digital indicator, pressure sensor with peak value. The indicator operated with one 3 volt battery (type CR2430), stopping automatically after 15 min.
• Packed in a transport case (with a set of optional accesories).

NDTJ

P-C-7281: for medium loads

• Up to 25 kN.
• The tensile load is applied to the fixing mechanically; hydraulics are used to register the load only. This enhances the systems reliability as it is not prone to hydraulic leaks. Also, mechanical loading provides smoother operation, eliminating hydraulic backlash.

P-C-7290M: for high loads

• Up to 100 kN.
• Maximum diameter: M20.
• The load application is achieved via a ratchet handle driving a 4:1 hydraulic multiplier; the applied load is recorded directly on a gauge mounted on the tester body. This compact design is lighter and more convenient to use than that of separate hydraulic pump and ram arrangements.
• An integral movement indication is provided allowing First Movement to be identified as well as total displacement before failure.
