Online PR News – 12-July-2011 – – Specialist bolt tensioner designer and manufacturer Boltight Ltd has teamed up with HevÃ¯ Technology to supply bolt tensioning systems to the worldwide mining industry. The partnership has already helped to secure a major contract in Zambia where custom-made Boltight hydraulic nuts are being used to replace conventional hexagonal nuts on the spider arms of two very large crushers.
Concern over the excessive time taken to disassemble the spider arm for routine maintenance using traditional methods prompted the equipment's owner to look at an alternative solution. Safety was also a major factor in the decision because applying and releasing the loads on the fasteners necessitated the use of large, heavy hydraulic torque wrenches that had to be manipulated in an unsafe overhead position.
To eliminate the risk of equipment failure and forced plant shutdowns it was decided that an advanced bolting method using a hydraulic tensioner system would deliver the optimum solution. Hydraulic nuts and tensioning is becoming increasingly important in the mining sector during the assembly, maintenance and repair of the critical heavy machinery used in extraction, comminution and refining operations.
Hevi provide QA, technical support and the specialized bolting systems required during initial assembly of large equipment. The company will also offer to investigate and resolve bolt failure and flange leakage on existing equipment.
Commented Hevi's Managing Director Jorg Albrecht: "While designers, engineers and constructors focus on plant efficiency, bolting is often a lower priority. These relatively inexpensive components can have a disproportionate impact on a projectâ€™s integrity, long life operation and ultimate profitability. That is why our unique and highly focused expertise, combined with Boltight's high quality tools, pays dividends for clients in this important industry."
