Tandem rollers are an essential part of asphalt paving– without compaction, there’s no roadway. Discovered on any roadbuilding task website, these makers have one task, and with a growing concentrate on accuracy compaction innovation, they are doing that task much better than ever. Today’s tandem rollers are likewise a focus for alternate drives, with a variety of electrical choices coming on to the marketplace. BOMAG concentrates on innovation The BW206 AD-5 AM tandem vibratory roller from BOMAG incorporates the business’s Asphalt Manager compaction system, which enables it to finish breakdown, intermediate, and surface rolling on high-production applications. Using an 84.1-inch compaction width, the maker has a 55.1-inch drum size that BOMAG states puts more effect area in contact with asphalt. When utilizing Asphalt Manager, the operator just requires to input layer density, and from there the system constantly determines compaction development while changing front drum vibration instantly in between real vertical and horizontal as the mat tightness boosts. Dynapac has actually presented 2 battery-electric tandem rollers. Dynapac electrical rollers Dynapac’s 2 Z.ERA tandem rollers, the CC900 e and CC1000 e, are battery-powered makers with the exact same efficiency as their diesel-powered equivalents. The rollers have running weights of 3,730 and 3,910 pounds respectively, and they are both powered by 48V lithium-ion batteries, which Dynapac states can a complete day’s operation without charging. Numerous charging services, consisting of 110/240V 1-phase alternatives, along with a quick charging choice, will be offered. The devices provide the very same fixed direct load, amplitude, gradeability, and take a trip speed as diesel rollers, however are quieter, have less moving parts, and have actually decreased upkeep requirements. Ammann’s light battery-electric roller decreases upkeep, sound, and emissions. Ammann electrical roller Ammann’s brand-new eARX 26-2 light tandem roller has no diesel motor or cooling system and couple of hydraulic parts. Ammann states its 48V LiFePO4 battery pack is distinct due to the fact that each internal battery cell is individually safeguarded to enhance flame resistance and boost security. The maker can run for approximately 18 hours on one charge. All of the electrical drive and vibratory motors are geared up with a recovery system– when the maker stops or vibration is shut off, power is created and returned to the battery to increase charge. HX Series pivot-steer rollers from HAMM change the DV+ line. HAMM Hamm pivot-steered line A brand-new generation of pivot-steered tandem rollers, the HX series, changes Hamm’s DV+ line. 9 variations are offered with running weights of 17,000 or 19,842 pounds. Numerous designs include 2 vibrating roller drums, an oscillation and a vibrating roller drum, along with mix rollers; vibration and oscillation drums are offered as split or non-split drums. Engines run at lower rpms, which minimizes fuel usage. Smart Compact, a compaction assistant that evaluates and evaluates information about asphalt condition and identifies the compaction requires separately for each drum, is a world initially, according to Hamm. Feline provides 10 tandem rollers in the 2- to 5-ton variety. Caterpillar little rollers Caterpillar’s 10 2- to 5-ton rollers are perfect for low- to medium-duty applications and the rental market. All are created with power management software application in addition to sophisticated hydraulics. Operator controls have actually been re-engineered to include rocker switches and easy-to-read screens. A two-inch drum balanced out enhances compaction performance, and a narrow frame style enhances exposure to the task surface area and drum edge. Optional Compaction Meter Value shows product tightness to the operator and removes unneeded passes.
