Expansion shell rock anchor AKR16TMPZ made of thread bar with diameter of 16 mm, manufactured according to TU 0950-003-83936644-2013.

Expansion shell rock anchor is designed for fixing the main and development workings on coal and salt pits, potash mines, and also at other mining enterprises. Fastening of the anchor rods is performed mechanically in boreholes with diameters of 32, 38, 41, 43, 45 mm, drilled in a hard rock with a compressive strength of at least 25 MPa.

Fastening in the hole is carried out by expanding the petals with a special wedge nut, which is screwed onto the anchor rod.
