Verify that attachment points (e.g., connection pins or hooks) are compatible with the bolter miner.
-
-
Securing the Chain:
-
Attach the chain’s fittings (e.g., clevis hooks or pins) to the bolter miner’s attachment points.
-
Thread the chain through the scraper conveyor path, ensuring proper engagement with sprockets or rollers.
-
Use at least two parallel chains for stability in heavy-duty applications, ensuring even load distribution.
-
-
Tensioning the Chain:
-
Use tensioners to adjust the chain to the manufacturer’s recommended tension, avoiding excessive slack or strain.
-
Ensure the chain is taut but not overstretched to prevent wear on links or scraper bars.
