At CONEXPO-CON/AGG in Las Vegas, USA March 4 to 8, 2014, the comprehensive display of Bobcat equipment at Booth 1501 will include the company’s first Tier 4 Final?/Stage IV compliant compact loaders alongside existing Bobcat models. The new Tier 4 Final/Stage IV 500 platform loaders feature a non-diesel particulate filter (DPF) engine solution and provide operators with all of the same performance benefits of the previous Tier 4 Interim/Stage IIIB models launched at the start of 2013.
The Tier 4 Final/Stage IV Bobcat non-DPF solution was achieved by designing an ultra-low particulate combustion (ULPC) engine. The ULPC is accomplished through a specially designed engine combustion chamber that significantly reduces the amounts of particulate matter created during combustion. As a result, Tier 4 Final/Stage IV emissions compliance can be achieved without using a DPF.
In addition to eliminating the need for a DPF, the engines used in the new 500 platform loaders provide a 4 to 12% increase in torque. This increase in torque is produced over a wide range of engine rpm, allowing operators of all skill levels to better utilize the machine's maximum performance.
The new Tier 4 Final/Stage IV S510 and S550 skid-steer loaders have a radius lift path, providing operators with the reach and visibility they require for dumping over a wall, backfilling or loading flatbed trucks. The new S530, S570 and S590 skid-steer and T590 compact tracked loader models feature a vertical lift path, providing operators with the ability to lift heavier loads higher, making it easier to clear high-sided truck boxes and hoppers, as well as placing pallets.
The new loaders feature a machine protection system that monitors, manages and shuts down the engine if needed. This system monitors engine coolant and oil temperatures and will manage engine systems to reduce the potential of these fluids reaching a point where the machine has to be shut down. This minimizes potential damage to the engine, stops unnecessary engine wear and keeps operators working.
Another new feature of the skid-steer and compact track loader line is cold weather protection. Whenever the engine temperature is too low, the loader will temporarily limit the maximum engine speed (rpm) to prevent premature component wear or failure. Engine idle speed is also raised slightly to help the engine reach its operating temperature faster. As soon as the engine warms up to a predetermined temperature, the protection mechanism will deactivate.
Cab-forward Design for Industry-leading Visibility
The new 500 platform loaders feature a unique cab-forward design that moves the operator closer to the attachment and provides unmatched visibility in all directions. The new loaders offer the largest cab door opening on the market, offering superior visibility to the cutting edge of the bucket or the corners of an attachment.
Windows on the sides and rear of the cab are larger in size to provide more visibility to the tires and the back of the machine. The larger top window makes it easier and more comfortable for the operator to see an attachment with the lift arms raised, an advantage when loading trucks or performing other tasks.
Operators want to spend minimal time on routine maintenance to start the workday earlier, and the new loaders are designed to work long hours in demanding conditions. Simple check points and superior design make it easier to perform maintenance correctly at the proper intervals. The auxiliary hydraulic quick couplers are mounted directly to the front plate of the lift arm to provide a solid mounting, and hoses are routed through the loader arms for better protection.
The hydraulic systems on the new 500 platform loaders have been engineered for higher standard flow and pressure, which provides increased attachment performance. Engine horsepower and hydraulic flow are matched to each of the loader’s rated operating capacity, size and weight — producing loaders that can outperform higher-horsepower compact loaders.
Operator Comfort is Paramount
Comfortable operators are more productive, so to create a better working environment, the 500 platform loaders feature a large cab, redesigned interior and improved cab pressurization. The loaders have a best-in-class pressurized cab with a new one-piece seal that goes all the way around the door and fits into a special curved pocket. This minimizes the amount of dirt and dust that might enter the cab, creating more enjoyable working conditions and making it easier to clean the cab.
Operators also have the choice between standard foot pedal hydraulic controls, the Advanced Control System (ACS) or the Selectable Joystick Controls (SJC) on all machine models.
Available on all new generation Bobcat loaders, the optional deluxe instrumentation panel intelligently monitors key loader functions - including fuel consumption - and the keyless start helps prevent theft. The 5-inch, full-color LCD screen offers better readability and operator interaction. Easy-to-read virtual sweep gauges allow operators to quickly read and understand the machine’s performance.
