Pit & Quarry, February 2019

Thanks to their close proximity Albrights trucks deliver crushed aggregate directly to the neighboring plants and despite traveling a short distance on a county blacktop are able to do so using their articulated dump trucks As soon as our trucks exit the property they cross the blacktop and head uphill to the asphalt and cement plants Albright says While spilled material equates to lost revenue for any operation Caldwell Stone is especially careful to avoid spilling on the public roadway Going up the hill rocks shift in the back and if the trucks at capacity materials inevitably spill out Albright says To prevent that we need to fill trucks to less than their rated capacity or equip each with a tailgate Without tailgates Albright estimates Caldwells 35 ton A35C Volvo hauls on average 25 to 30 tons depending on the materials a problem the quarry has dealt with for decades To combat this Caldwell added tailgates to some trucks but the company experienced mixed results TAILGATE TRIAL AND ERROR Before Albright joined the quarry full time his father and grandfather bought tailgates for the Volvo dump trucks which deliver Albright to the nearby plants While Albright doesnt recall the brand or year the tailgates were purchased he hasnt forgotten the hassle of keeping up with repairs Leaving the quarry large rocks would tumble down the bed and hit the tailgate breaking frame welds and cables Then according to Albright during a period of heavy stripping the tailgates were damaged so frequently and severely that they were bending and breaking off the frame Initially we kept up with repairs Albright says Wed remove the tailgate which takes about an hour repair the welds and straighten out the dents and other damage Eventually though they became so bent out of shape that we gave up During the past dozen years Albright estimates the tailgates were a problem for six to eight of those years For the last few years the tailgates sat abandoned and defeated leaning against the side of a building In the end they were more work to maintain than they were worth Albright says If we didnt know better we may have kept repairing them but we know from experience how a good tailgate should hold up After all they have a benchmark for comparison CONTRASTING TAILGATES Before deciding to experiment with HAULING Philippi Hagenbuch relies on its hinge and leverage system which opens at a steady rate as the truck body lifts providing the largest possible opening clearance at full dump you could reduce time required for bearing changeout Scan to view informational video When a bearing needs to be replaced the Time Saving performance mounted ball bearing allows for easier bearing removal The patented axial groove in the inner ring bore allows for easier bearing removal and ability to reuse the shafting with minimal clean up saving more than just time www regalbeloit com Creating a better tomorrow ª Regal Creating a better tomorrow Sealmaster and Time Saving are trademarks of Regal Beloit Corporation or one of its affi liated companies 2016 2019 Regal Beloit Corporation All Rights Reserved MCAD18046E 10044E 40 PIT QUARRY February 2019 pitandquarry com
