LiuGong used Intermat to intro its newly acquired Dressta dozers and 922E excavator, which features a high-contrast monitor that can be seen in all light conditions. Both machines are made in the company's Poland plant, which is scheduled to manufacture wheel loaders. from the 922D, and im- proves operating effi- ciency by 10 percent and reduces fuel consumption by 18 percent, according to the company. The ma- chine's automatic power boost mode increases digging force by up to 10 percent for 10-second intervals. The heavy lift system lets operators in- crease hydraulic pressure to build force and reduce hydraulic flow to the at- tachment, while reducing speed for added control during lifting operations. The system of auto- matic compaction con- trol on BOMAG rollers has been upgraded with Asphalt Manager II (AM II). New features include an easier-to-use operating system with menu control that provides operators with several options for basic applications (e.g. surface layers; binder and base courses). All of the GPS-fitted rollers working a project are connected by a wireless network, allowing individual measuring data (includ- ing position, compaction values and asphalt tem- perature) that is updated every five seconds, to be shared with each other and the site manager. The overall status of the site is recorded in real time. Goodyear introduced a new range of OTR tires with Hi-Stability technolo- gy. The tires can increase load capacity by up to 25 percent and improve sta- bility. More than 30 radi- als have been developed for machines operating in mines, quarries, construc- tion, ports, recycling and other industries. With equipment manufacturers producing more power- ful machines, Goodyear says it developed the tires to match their increased power, speed and torque. The construction of the Hi-Stability tires allows higher inflation pressures. Improved stability and durability come from a reinforced bead structure and carcass, and the tires provide better tread self- cleaning and reduced fric- tion for improved rolling resistance and traction. Material lifting special- ist Haulotte used Intermat to announce a 23 percent increase in sales in the last year and optimism about a "pretty good" global market. Strong fleet replacement and rental orders are boosting American sales, says the company which antici- pates a "very good" North American market this year. The company also introduced upgrades to its compact scissor lifts with new Tier IV compliant Kubota engines. These compact machines have excellent rough-terrain capability, says Haulotte, with four-wheel drive, im- proved ground clearance, a new outrigger system and a hydraulic differen- tial lock to aid work on steep slopes and rough- terrain. Haulotte previewed its HT23RTJ rough-terrain telescopic boom. The machine will be available in October 2012 in North America. The boom can reach full height in 53 seconds and comes with three steer set- tings: two-wheel steer, four-wheel steer and crab. Better Roads June 2012 39f
