ConExpo launch for Bobcat 500 compact loaders
Bobcat to showcase latest Tier 4 Final- and Stage IV-compliant models alongside existing machines
BOBCAT will be displaying their first Tier 4 Final/Stage IV-compliant compact loaders at ConExpo 2014. The new 500-platform loaders, which will be displayed alongside existing Bobcat models, feature a non-diesel particulate filter (DPF) engine solution and provide operators with the same performance benefits as the previous Tier 4/Stage IIIB models launched in early 2013.
The Tier 4/Stage IV Bobcat non-DPF solution was achieved using an ultra-low particulate combustion (ULPC) engine with a specially designed engine combustion chamber that significantly reduces the amount of particulate matter created during combustion.
In addition to eliminating the need for a DPF, the engines used in the new 500-platform loaders are said to provide a 4–12% increase in torque over a wide range of engine revs/min, allowing operators of all skill levels to utilize the machines’ maximum performance.
The new S510 and S550 skid-steer loaders have a radius lift path, providing operators with the reach and visibility required for dumping over a wall, backfilling or loading flatbed trucks.
The latest S530, S570 (pictured) 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 and making it easier to clear high-sided truck boxes and hoppers, as well as placing pallets.
The Tier 4 Final/Stage IV-compliant loaders feature a machine protection system that monitors, manages and shuts down the engine if required.
Another key feature of the skid-steer and compact tracked loader line is cold weather protection. Whenever the engine temperature is too low, the loader will temporarily limit the maximum engine speed (revs/min) to help 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.
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, providing the ability to outperform higher-horsepower compact loaders.
Operators have a choice between standard foot pedal hydraulic controls, an advanced control system and selectable joystick controls on all machine models.
