SPLIT SET / FRICTION BOLT BEARING PLATE & COMBI WASHER FOR SPLIT SET / FRICTION BOLT
Split Sets / Friction Bolts have been used as a primary roof support in the underground mining environment for many years. The Split Set consists of an open seamed high tensile steel tube with a face plate. One end is tapered for easy insertion into a pre-drilled hole. It is installed by driving the assembly into a marginally smaller hole than the split sets diameter and the welded steel ring then provides the necessary support to hold the washer plate in place. The split set then uses friction to anchor itself along the whole length of the bolt by relying on the radial spring force generated through compression of the tube. Split set technology is used worldwide by many mines for an extensive variety of mining applications.
Key Advantages of using Split Sets
Fast and easy installation
Full length support
Effective support at any angle
Axial and radial support
No torqueing or re-torqueing
No special equipment is required
Improved rock stability
The Split Set is a popular choice due to its easy installation. Once the hole is drilled, the driver tool drives the anchor into the wall. Installation time is typically less than a minute and there is no waiting time for grout to set, no tightening or torqueing and no ongoing maintenance is needed after installation. This saves time, labour and additional grouting or resin expenses.
Split Set / Friction Bolts are available in 33mm, 39mm, 41mm and 46mm diameters in a variety of lengths to suit the application of the mine. The domed bearing washer plates are available in 125 x 125 x 4mm and 150mm x 150mm x 4mm as well as the Combi Washer Plate 300mm x 270mm x 1.6mm.
