WIBOREX injection drill bolts are steel rods made of finegrained construction steel equipped with coarse thread that can be used as consumable drilling bar, reinforcement pipe, and injection pipe. The elongation with coupling sleeves, the using of different drill bits and the bracing with nuts and plats are possible due to the thread.
WIBOLT Rock Bolts are applicated in mining and tunnelling. These systems are distinguished from resin and anchor mortars not only in their setting method but also in their application. They are available in different types, depending on the application.
With the BOLTEX friction bolt, the MINOVA CarboTech sales a well proved product applicated in mining and tunnelling. The bonding to the rock results from the friction which is formed between the extended-bolt and the rock. Friction bolts can be subjected to the full load directly after they have been positioned and are immediately able to absorb the rock movements. The carrying force is applied along the complete length of the inserted bolt.
Compared with aluminium or steel, glass fibre reinforced plastics (GRP) have advantages that can be traced to the properties of the composite material: high resistance to corrosion and higher nnnn
specific strength. Depending on the application and at constant load, a GRP bolt can yield a nnnnnn
