ALWAG offers a complete program of products for mining and tunnelling.
Products after international quality standard combined with a mature logistic
make it possible for ALWAG to react immediately to customer needs. The
strength of the company are customer-tailored system solutions which are
implemented fast and flexible.
Safety and patent solutions
for problem zones is their strength. Most of them outcomes directly in
practise on site.

ALWAG - TECHMO set an exceptional milestone in the history
of Forepoling systems technology by developing the AT Pipe roof systems
with standard tube diameters of 76, 89, 114, 139, 168 mm tube outside
diameter. The long experienced AT-System solution drastically scales back
costs and the time required. Compared to conventional products, the AT
full system solution is designed to meet customer's individual needs.
The new innovative system includes AT-Drainage system and AT-Injection
system with fibre-glass tubes. Special attachments are available to automate
the AT Pipe roof system.
The drilling systems
brought by AT rank among the most modern capped drilling systems in the
international market.

Safety, protection, and time saving are vital factors AT take into account
when developing, planning, and implementing their product systems. Innovative,
remote-controlled AT automation warrants for greater safety at work, reduces
ancillary times, features a smaller saw tooth profile for pipe roof umbrellas
and reduces the amount of staff needed. AT automation: safe, quick and
inexpensive.

The AT-Power set is a selfdrilling friction bolt for the Mining- and Construction-
Industry. The range of application is very wide and the advantage is the
higher safety to install the AT-Power set compare to other bolts. The installation
of the AT-Power set is simultaneously with the drilling of the hole and
the bolt is set. The elastic characteristic of these bolt will accept movements
by the surrounding rock without loosing its pull out capacity. An automation
for approximate 6-7 bolts will be available to install bolts by use of remote
controlled commands. |

These are fully threaded, hollow core, cold rolled anchors with continuous
outside thread suitable for attaching bits and couplings, which also forms
a superb mortar connection. They are supplied with couplings, anchor plates
and nuts, and five bit designs are available.
IBO Self Drilling Anchors are used for temporary and permanent stabilization
in NATM; retaining walls in confined spaces; and slope stabilization for
roads, railways, and tunnel portals.
Whether used in cohesive or non-cohesive ground, the IBO anchor can be grouted
and then stressed and locked off with a hexagonal nut and plate. Advantages
are: similar installation for all ground conditions; no casing required;
fast drilling and anchoring in a single operation; choice of bits and anchor
loads; and hollow core for high-volume flushing and grouting. |

IBI face support anchors are similar in specification to the IBO anchor,
but with a continuous inside thread, while the couplings have a continuous
outside thread. This allows a post grouting coupling with a pressed middle
stop to be inserted into the drillstring, with a rubber cuff that creates
a post grouting valve for multiple re-injections. This affords a means of
consolidation of the most fractured and non-cohesive ground. |

This attachment stabilises the drill hole during installation of the IBO
/ IBI anchor, and facilitates a full mortar covering in the annulus. It
allows boring and injection in one step, giving a high flush and injection
quantity through its large internal cross-section, while saving time on
connections. A mixer pump is available, for all materials up to 7 mm and
a pumping pressure of up to 40 bar. |
