JM CABLE® Non-Tensioned Cable Bolt
Drill borehole approximately 1" to 1-1/2" longer than the bolt length. Measure from where the plate touches the roof to the top end of the bolt.
Insert the appropriate length and type of resin cartridge(s) as specified in the roof control plan into the drillhole. Care should be taken to insure the resin cartridge is not broken before inserting into the hole.
Using the cable bolt, push the resin and bolt as far a possible into the drillhole by hand.
With the square head of the cable bolt in the bolt wrench, push the JM Cable Bolt to the top of the hole. If the bolt is equipped with a stiffener tube, insure that the stiffener tube enters the hole smoothly. When the stiffener is collared in the drillhole, slow clock-wise rotation of the cable bolt is permissible to aid in final penetration and begin mixing of the resin.
Once the cable bolt is completely collared in the drillhole, and with the plate slightly off the roof without excessive upward boom pressure, clock-wisely rotate bolt rapidly to mix resin for amount of time as specified for resin used. Always keep hands away from rotating parts.
When the proper mix time has been achieved, stop rotation, wait for 3 seconds, thrust the head of the JM Cable Bolt with plate tight against the roof using the bolt machine boom pressure. Hold tight for amount of time as per resin manufacturer’s recommendations to allow resin to set up. Do not attempt to rotate bolt once resin sets up. This completes installation.
Note: JM CABLE Non-tensioned Cable Bolts are available for both 1" and 1-3/8" drillholes and either regular (brite), galvanized, or cableox epoxy coating.
