Vermeer announced the addition of two new models, the D24x40 S3 and D40x55 S3 drills, to its lineup. Both offer significant diminution of sound with a guaranteed maximum of 104 decibels, successfully cutting sound levels virtually in half.
Such a reduction was achieved by two methods. The sound and air from the oil cooler is directed toward the back of the machine, then released out the top. From there, it doesn't target anyone standing at the rear of the machine. Additionally, a hydraulically-operated cooling fan manages revolutions per minute (rpm), which helps mitigate noise.
Lower sound levels are important because the quiet allows easier and better communication among the crew. It also helps reduce irritation, which is common in urban construction zones.
Designed with water and gas distribution contractors in mind, the D24x40 S3 has 28,000 pounds of thrust and pullback, which is a 10 percent increase from its predecessor, the D36x50 Series II, while maintaining the same footprint thanks to its larger displacement motor. It is powered by a 125-horsepower 4.5-liter John Deere 4045 engine and boasts a carriage speed of 240 feet-per-minute and a rotation speed of 270 rpms.
The machine has the ability to install 2- to 16-inch diameter utilities and possesses 5,500 foot pounds of rotational torque. The unit's 188-feet-per-minute carriage speed is 7 percent faster than its predecessor.
Contractors can now select from three drill rod options: 10-foot rod in 2.38-inch or 2.63-inch diameters and 15-foot rod with a 2.63-inch diameter. Both the 24-by-40 S3 and the 40-by-55 S3 have the same common controls seen throughout the S3 lineup.
