Lokset™ Products

Lokset products are polyester based resins designed for rock-bolting and fastening of short anchoring elements.

We have manufactured Lokset resin capsules since the late 1960's and are the leading supplier and innovator in this field. Our development and manufacturing ensures security of supply, service and support.

The Lokset system consists of an easily handled cartridge, containing a highly reinforced polyester resin component, together with its catalyst, in accurately measured quantities. The rotation of the bolt during installation ruptures the capsule, shreds the skin and mixes the two components causing a chemical reaction and transforming the resin mastic into a solid anchor.

The Lokset resin capsule series is available in multiple configurations of single/double length combinations, diameter, set time, set time combinations, viscosity and shelf life.

 

Did you know?

The oldest reference Minova has for Lokset® resin anchors was the strengthening of the London Heathrow Airport road access tunnel in 1963 to allow heavy jets to land. Since then there have been numerous applications across the world in mining applications, highway tunnels, civil applications and a submarine base.

Lokset Accessories

We provide a comprehensive range of auxiliary products for the fast and easy application of this innovative product.

Resin Capsule Parachutes

Parachutes are recommended when Lokset™ resin capsules are air-loaded into rock bolt holes. The parachute guides and protects the capsule while it travels at high speed through the loading tube into the hole, then holds the capsule up the hole until the bolt is inserted.

Instructions for use:

  • Gently force the resin capsule into the open end of the parachute
  • Load the capsule into the capsule gun so that the parachute is on the front end
  • Fire the capsule into the hole

Resin Capsule Top Hats (Retainers)

Resin capsule top hats are made from recycled plastic and are used to retain resin capsules in rock bolt holes, until the bolts are inserted. This frees the operator to use both hands for other tasks such as lining up the rock bolt and operating the bolting machine.

Instructions for use:

  • Insert the resin capsule into hole.
  • Push in the top hat behind the resin capsule.
  • If multiple capsules are used, push in a top-hat behind each one

Resin Capsule Injector

The resin injector is used to load Lokset™ resin capsules into roofbolt holes, and consists of a plunger within a hollow tube. Each Resin Injector is tested in our laboratories prior to dispatch.

Instructions for use:

  • Remove the plunger from the outer tube.
  • Insert the appropriate size polytop into one end of the outer tube.
  • From the other end, insert the Lokset™ resin capsules
  • Push the injector against the roofbolt hole opening, and push the plunger until the resin capsules and polytop are inside the hole.

Quick-Chem™ System

The Quick-Chem™ Lokset™ resin capsule insertion system ensures safe, fast and complete insertion of resin capsules. The system consists of a specially designed cap suitable for attaching to Lokset™ resin capsules and an insertion tube that carries the resin capsule(s) to the back to of the holes and is then removed for re-use.

Instructions for use:

  • Securely attach appropriate Quick- Chem™ cap to the end of the Lokset™ resin
  • Place the capsule with the cap attached in the Quick-Chem™ insertion tube
  • Fit the tube to the shank of the drifter
  • Collar the tube in the hole and push into the hole until the resin capsule cannot be seen
  • Withdraw the tube
