Stacker Reclaimer Belt Tensioning Cylinder<\/h2>\n

A loose belt slips. A tight belt wears. The tensioning cylinder finds the balance \u2014 maintaining constant, optimal tension on the conveyor belt as the boom pitches, the load varies, and the belt stretches over thousands of hours of operation. The smallest cylinder on the stacker reclaimer, but the one that keeps the whole conveyor system running.<\/p>\n

Why Constant Belt Tension Is Critical for Conveyor Performance<\/h2>\n
<\/div>\n

\"Stacker<\/p>\n

The conveyor belt on a stacker reclaimer runs continuously during operation, carrying hundreds or thousands of tonnes of bulk material per hour. Belt tension must be maintained within a narrow range: too loose, and the belt slips on the drive pulley (losing power transfer and causing belt wear); too tight, and the belt, bearings, and structure experience excessive stress (reducing service life and increasing energy consumption).<\/p>\n

The belt tensioning cylinder pushes against a take-up pulley at constant hydraulic pressure, automatically compensating for belt stretch (new belts stretch 1\u20132% in the first 1,000 hours), thermal expansion\/contraction, and load variations. As the boom pitches up or down, the belt path length changes \u2014 the tensioning cylinder absorbs this change by extending or retracting, maintaining constant tension throughout the pitching range.<\/p>\n

Korea Ever-Power supplies the belt tensioning cylinder individually or as part of the complete stacker reclaimer set with the skeleton pitch (#27) and chaser pitch (#28) cylinders. Browse the offshore hydraulic cylinder<\/a> range.<\/p>\n<\/section>\n
