Bobcat’s first Tier 4/Stage IV final compliant compact loaders will be making their official global debut at ConEXpo 2014.

The new Tier 4/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 interim Tier 4/Stage IIIB models launched at the start of 2013.

The Tier 4/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.

In addition to eliminating the need for a DPF, the engines used in the new 500 platform loaders provide a 4 to 12 percent increase in torque. This increase in torque is produced over a wide range of engine rpm, allowing operators of all skill levels to better utilise the machines’ maximum performance.

The new Tier 4/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 Tier 4/Stage IV compliant 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 minimises 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.
