ROMTECH Geotechnical supplies components for stressing and testing soil nails either to buy or to hire. The photograph below shows a typical layout, but we can also supply specialist equipment such as electric pumps, various jacking columns and specially manufactured frames to your specification.

The anchor traction tests are made with a hydraulic cylinder (6) which is set under pressure by a hydraulic manual pump (9). The relative force is indicated on a manometer in tons.
More exact values (±5%) can be obtained using an additional dynamometer box. The entire system is easily to transport, simple to handle and needs neither compressed air not current.

Preparation

The contact surface on the rock should be plane and right-angled to the rod. As surface and equalizers serve the plate (3) and the metallic set of wedges (2).
