guide to new and updated equipment and supplies in the aggregates industry. Your complete by Kerry Clines, Senior Editor Improved fuel economy, performance Case Construction Equipment says its new 621F wheel loader provides up to a 10-percent increase in fuel economy over the previous model, while delivering faster acceleration, quicker cycle times, and higher travel speeds. The loader features a 6.7-liter Tier 4 Interim-certified engine that delivers up to 162 horsepower, a 2.75-square-yard bucket capacity, and an operating weight of 26,641 pounds. A new dual-mode shutdown feature maximizes fuel economy and monitors vital engine components. The operator can limit idle time by using the fuel-saver mode; desired shutdown time can be set in five-minute increments. The new loader includes standard limited-slip front and rear axles for traction in all conditions. Optional heavy-duty axles with locking front and conventional rear dif- ferentials help reduce tire wear when working on hard surfaces. The standard four-speed transmission with manual kick-down capability provides traction and increased bucket penetration. Award-winning joystick steering enables operators to move seamlessly between the joystick and steering wheel. The PowerInch feature maintains high RPMs to maximize hydraulic power and control, allowing the operator to approach targets in tight areas quickly and precisely, regardless of engine speed. The cab offers an unobstructed view to both edges of the bucket or attachment; a wide window and sloping hood provide clear vision to the rear. A new rear- view, wide-angle camera with adjustable color monitor is available to eliminate blind spots. An advanced instrument cluster monitors fuel consumption and enables the operator to adjust various functions without relying on a service technician. The cab also features ergonomically placed controls and a new heated cloth seat with seven adjustment modes. Write 51 on reader card. Delivers power, versatility Kobelco added the SK210 full-size, high-performance excavator to its Tier 4-Interim Mark 9 series. The SK210 is said to deliver a 10-percent improvement in both fuel efficiency and productivity, with more power and faster engine response, thanks to its Power Boost feature. A Heavy Lift feature delivers 10 percent more lifting and swing capability on command, without time limit. The excavator features an upgrade to its intelligent hydraulics, a new economy power mode, a new ROPS/ FOPS-certified cab, and a low engine cover and standard rear-view camera for improved visibility. A fully automatic engine and hydraulic warm-up system heats the hydraulic circuit to 126 degrees F to improve system efficiency and reduce component wear. Integrated swing priority provides smooth transition of additional pump power to the swing function. Automatic hydraulic regeneration feeds the cylinder demanding oil first, with oil that is being pushed out of another cylinder. The independent travel feature, activated with a switch, dedicates a pump to travel motors for better movement while performing other functions. Additional features include swing flashers and step exten- sions, as well as plug-in capability for telematics. An optional, severe-duty undercarriage is available, as well as an optional special application package featuring high and wide undercarriage, reinforced frame, guarding, auxiliary hydraulics with ex- tra rotation pump, and provisions for a cab riser.
