M 318 and M 320 Material Handlers combine the versatility of a wheel excavator with the specific purpose of a material handling machine.
Standart MH models offer a straight boom, a material handling drop nose stick and extended outriggers. The M 320 MH also has a 600 kg additional counterweight.
Heavy lift hydraulic circuit and solid tires are available as options. Solid tires are recommended in a scrap handling applications.
Other options such the waste handling package and large mesh radiator help maintain a cleaner cab and radiator in waste application and dusty conditions.
M 318 and M 320 Material Handlers can be available with fixed cab riser or with hydraulic cab riser.
A fixed cab riser is offered for standard and material handling machines, where a high viewing position is needed. It can lift the cab by 1,2 m.
A hydraulic cab riser is designed to meet customers needs for easier operation and greater stability. It provides high flexibility in cab hight. Hydraulic cab riser in the top position raises the cab by 2,0 m. This provides optimal viewing to all sides in different applications such as log handling, scrap handling and various load / unload tasks. In medium position the hydraulic cab riser places the cab forward by 0,5 meters more than in the travel position, for increased visibility. In bottom position it is used for shipping and travelling.

Caterpillar machines help maintain and preserve the fragile environment.
The IT28G is designed to provide more performance than ever before in a machine of this size. That means more work done in a day, less fuel consumed and minimal impact on our environment.
The IT28G uses the Cat 3116T low emission engine. This engine is designed to meet the worlds toughest emission regulations. Refinements to the turbocharger, cylinder head and pistons improve fuel combustion so there are less emissions. Plus there is a new system that closely controls fuel-to-air ration to help burn fuel efficiently and cleanly.
The IT28Gs new engine cooling system allows the engine to be fully enclosed so less engine noise escapes. Not only does the operator notice a significant drop in machine sound levels inside the cab, but spectators outside hear less noise too. The cooling fan traditionally a major contributor to noise, is now hydraulically driven. The result is cool, quiet operation with less disturbance to the environment. And IT28G is even quiter with the optional sound suppression package.
To help protect the earths ozone layer, the IT28Gs air conditioning unit uses only R-134 a refrigerant which does not contain harmful chloro-fluorocarbons (CFCs).
Engine oil, transmission and hydraulic filters are positioned vertically and are easy to reach so they can be removed without spilling. Lubricant filters and drains are also designed to minimize spills.

|
|
The IT28G offers excellent performance in a wide variety of applications such as bucket loading, material handling, utility work and industrial support.
Operator station is designed for total control in a comfortable, spacious environment. All controls levers, switches and gauges are positioned to maximize comfort and productivity. Two-door cab offers exceptional ventilation and easy entry and exit. Full-length glass windshield with silicone joints enhances visibility.

The Quick Coupler is an integral part of the Caterpillar Integrated Toolcarrier. Tool changes are quick and easy. Activation of a third hydraulic valve to engage and disengage attachments is a simple lever movement from the operator seat.
Quick-disconnect hydraulic couplings at the Quick Coupler permit fast, easy connections of remote hydraulic lines to power attachments with multiple hydraulic functions.
A wide selection of tools are available from Caterpillar.

Structures
The 539 knuckle boom loaders main structures (main frame, platform frame and boom and stick) are purpose-built for the stress loads of pull-through delimbing and truck loading.
Attachments
Factory installed options include a fifth-wheel trailer, pull-through-delimber with topping saw, continueous rotation grapple etc.
Engine
The turbocharged and aftercooled Cat 3126 DITA engine provides optimum power and fuel efficiency. The four-stroke cycle design delivers long power strokes and efficient fuel combustion with low emissions. The engine is easily maintained. All engine service points are located on the back side of the engine and are easily accessed, through swing-out doors at the back of the loader. Turbocharger enhances performance and engine efficiency, especially at high altitudes by packing more air in the cylinders for excellent combustion. Jacket water aftercooler reduces smoke and emissions by providing a cooler, more efficient combustion. This also extends the life of the piston rings and bore.
Air intake heating eases cold weather starting. Individual, high-pressure unit injectors increase fuel economy with low emissions. The radius cone injector nozzle provides excellent contact with the cylinder head sleeve to ensure tightness with the combustion chamber.
