Features

• Standard 47mm Friction Lok Bolt installed using percussion. The slotted tube provides both radial and axial restraint to rock movement

• Bolt has full 180kN capacity in all ground conditions

• Easily installed in very poor ground

• A radial crimp is located at the tail of the Friction Lok Bolt, housing a Mechanical Point Anchor

• The Mechanical Point Anchor has a hex drive which locates into drill/dolly drive assembly when the bolt is mounted onto the drill boom

• Once the Friction Lok is installed, left hand rotation is applied to the Mechanical Point anchor, actuating the drive and expanding the bolt tail

• Once expanded, the Mechanical Point Anchor has a non-seizure load of 240kN, exceeding the Friction Bolt UTS

• Simple, efficient and low cost

Features• The rock bolt assembly is suitable for hard rock

applications, tunneling and mines especially where aggressive ground contaminants are present.

• M24 Bolt JBX bar Gr.650/890MPa. JX rock bolt profile provides superior load transfer characteristics using the unique ‘J’ bar pattern

• The Aussie Bolt is a mechanical point anchored, pre tensioned, post groutable rock bolt with a grout injection nut head. All incorporated in a polyethylene sleeve

• The expansion shell will give the bolt a preload load of 12T before grouting

• Polyethylene convoluted tubing with a 2mm Wall thickness –Giving 50 -100 Year corrosion protection

• Recommended for drill hole size 45mm diameter

• Hand held or mechanically driven assemblies available for installation

• Screwed on Grout adaptor for high pressure grouting through 67mm nut head

Bolt and accessories can be supplied black or galvanised. All standard lengths are available and any length can be produced upon request.

Spin times will depend on total capsule length, as a guide spin at max rpm and feed gradually through the entire length of the capsule at a consistent rate ensuring the bolt reaches the back of the hole in 10-15 seconds and spin for a further 2-4 seconds at the back of the hole. Note: high temperatures may necessitate a reduction in spin time, consult Jennmar for further advice.

• The Sorrich “Clip Up” hook has been developed for underground application and designed to hold four inch (110mm) Polyurethene Pipe

• Load rated hanger to 800kg WLL

• The diameter of each separate hook is 120mm, allowing enough room to easily slide “poly” inside the circumference of each hook and just enough room for the poly pipe to be held firm inside the hook to reduce movement. Each 4-inch poly line are then locked in place by our patented locking system, which integrates with the Minsup clip for quick and easy installation. The “Clip Up” is made from 6mm galvanised mild steel for strength and to prevent rusting in normal underground environments

• The top is an open 2-inch (66mm) hook for possible temporary 2-inch poly pipe or for use with power or pump cable, which prevents tangles amongst other lines.

• The backside of the hook has been designed to be capable of clipping back to the mesh or rock bolts with a simple “D” shackle when hanging in the ‘’shoulders”.

• This product is the only one of its kind on the market and it is the safest, fastest and neatest way to install poly pipe.
