Additional information

Product Name

FTA

Applications

Designed for the support and reinforcement of underground mine workings.

Component Description

A cylindrical steel tube made from a specialized profile. It is manufactured from special steel, either black steel or hot-dip galvanized steel.

Key Advantages

► Full load-bearing capacity immediately after installation
► Anchorage along the entire length of the borehole
► Can be installed using either a drilling rig or handheld rock drills
► FTA anchors are available in black steel or hot-dip galvanized steel, with lengths ranging from 600 mm to 3,000 mm and diameters from 39 mm to 49 mm

Operating Principle

The anchor is installed into a borehole with a diameter smaller than that of the anchor itself. Due to the elastic properties of the steel, the tube expands against the borehole walls, generating frictional forces that securely hold the anchor in place. The bearing plate distributes the load over a larger area, increasing the effectiveness of the support system.

The FTA can be used either as a standalone support element or as part of reinforced combined support systems, for example in conjunction with reinforcement cages or welded wire mesh.

The corrosion-resistant coating allows the anchors to be used in aggressive underground environments, extending their service life and improving the reliability of the support structure.
