Volvo Construction Equipment keyed in on effi ciency gains with the launch of the Tier 4 Final EC250E and EC300E crawler excavators, which has features that optimize hydraulic fl ow while minimizing pressure losses. With the ability to manually control the fl ow to the hydraulics using an integrated work mode system, the operator can choose the work mode based on the job. A boost in productivity is achieved with Volvo's ECO mode, which reduces fuel usage without reducing performance. An optional automatic idling and auto-engine shutdown system allows the operator to set the controls for between 3 and 20 seconds, after which the engine speed will be automatically reduced to idle if the machine's controls are inactive. If the machine is motionless for 5 minutes, the engine will automatically turn off. Machine controllability is improved via a proportional two-pump fl ow that allows for a high quality grading fi nish in less time. Com- bined with the full electro-hydraulic control system, the high pump fl ow also creates faster response and cycle times, and an increased pump input torque further boosts cycle times. Comfort and convenience are addressed through the excavators' advanced human ma- chine interface, which ensures the best place- ment of joysticks, keypad and LCD monitor for control, comfort and effi ciency. Additional features include an attachment management system that stores the settings for up to 20 different hydraulic attachments and an After Treatment Control Module that that controls, monitors and diagnoses the aftertreatment system to ensure emission regulation compli- ance. The E-Series excavators also feature a heavy-duty superstructure with reinforced idler frame, track links and bot- tom rollers.

Powered by a 4-cycle 3.2-horsepower GX 100 Honda engine, the new units join a rammer lineup that includes 2-cycle oil injection models and premix 2-cycle and diesel models. The BS 50-4As and BS 0-4As feature low oil shutoff technology that detects if the machine has low or no oil and will not al- low the engine to start. A purge bulb that evacuates air from the fuel line ensures easy starting, and a compensated carburetor ensures optimum air-to-fuel ratio to deliver air fi lter change intervals up to three times longer than previous models of rammers. A four-stage air fi ltration system, available on all Wacker Neuson rammers, includes a main element with 20 percent more capacity than the previous design. The rammer's motion self-cleans the unit, and a cyclonic pre-fi lter provides more effi cient dirt removal. Also, a fourth stage fi lter prevents dust ingestion during fi lter changes.
