“We decided to modify all our trucks with intake hoses and valves so we can plug in on the side of the truck,” Miller says. “This saves someone from climbing on the truck while holding on to a hose. Now both hands are in contact with the truck while ascending and descending. It’s much safer.”
The addition of a second storage tank enabled Miller Sealcoating & Striping to offer his customers a choice between a more-expensive refined coal tar sealer and an asphalt-based sealer. By a wide margin customers opted for the more-expensive sealer in 2011.
“We originally had a bracket made for the roper pump so we could couple a hydraulic motor to the shaft,” Miller says. “We couldn't get the rpm's we needed without increasing the hp of the gas motor (which was costly). We decided to switch to sprocket and chain so we could increase the speed exactly where we want it.”
“We used to have six guys shouldering bags of sand,” Dan Miller says. “It took a long time and wasn’t safe.”
When West Virginia’s Miller Sealcoating & Striping acquired a local competitor in 2008 the contractor also acquired a second bulk storage tank. It sat unused until 2011 when owner Dan Miller installed the tank in his yard, next to a bulk tank for asphalt sealer and a 30-ton sand silo. To give his customers a choice, empowering them as they make their buying decision, he filled this second tank with a polymer-modified coal tar sealer. A rebuilt 100 gpm chocolate pump (as in Hershey’s chocolate), converted to handle sealer, pumps material from tank to truck, and now one driver can fill a truck in 10 minutes, pull beneath the sand silo, and be out of the yard in less than 30 minutes.
