Reliable, heavy-duty booms increase uptime and reduce repair costs.
The main booms are constructed in a box design with thick walls and strong welds.
The ends and middle of the main booms are cast, which is stronger and lighter than fabricating.
Steel tube hydraulic lines provide extended life and effectively dissipate heat.
Major structures and components are built to be rebuilt, reducing waste and replacement costs.
ACERT Technology reduces engine emissions at point of combustion with less moving parts for lower operating costs.
High swing torque, swing speed and lift capacity of Cat knuckleboom loaders reduce cycle times and lower cost per ton.
The heavy-duty structures of these loaders makes them the right choice for high production, high cycle applications or when handling big hardwoods. The rugged upper frame includes cross plate head side reinforcement for severe delimbing applications.
Simple, clean and engineered for long life providing a rock solid base for optimum stability.
Wide stance stabilizer legs and cylinder mounted lock valves resist side pulling and provide 360 degree stability for heavy lifting.
Easy changing of engine, fuel, pilot and case drain filters.
Eliminates contamination backflow during filter changes.
Allows capturing of fluids for easy draining without spillage.
An electric refill pump to add oil into the hydraulic tank maintains system cleanliness by passing all oil through the filtering system.
Easy priming of the fuel system after a service interval, eliminating the potential of fuel contamination.
Large access openings provide easy serviceability of fittings and connectors. Oil level check is accessed on the platform.
Isolated cooling cores can be individually removed, reducing service times.
The Cat C6.6 engine with ACERT Technology gives exceptional power and fuel efficiency, while meeting U.S. Environmental Protection Agency (EPA) Tier 4 Interim, EU Stage IIIB emission standards. This engine includes electronic governing, cold mode start strategy, automatic altitude compensation, electronic diagnostics and fault monitoring.
An enlarged side by side engine coolant, hydraulic, and charge air cooling package allows efficient heat rejection. Individually isolated cooling cores eliminating core to core thermal stresses to greatly increase durability.
The large 864 mm (34 in) diameter electronically controlled variable speed fan is speed modulated to provide cooling only as required, resulting in reduced noise levels and lower fuel consumption.
The new Cat C Series is more fuel efficient and productive than the previous models. You can move more wood and lower your cost per ton.
A choice of operating modes give you the flexibility to match hydraulic power to the job. For normal loading operations, the Economy Mode provides fast cycle times and the most fuel-efficient performance.
The booms and base structures are specifically designed for loading and delimbing applications, providing the strength and durability that allows for a long service life.
Allows tracking of operational parameters to ensure optimum utilization and on time service intervals.
The loader control system includes an automatic engine idle down feature to reduce fuel consumption during periods of inactivity.
The HD front window guard provides an extra level of safety while handling large trees and building high wood piles.
The reverse slope front window stays clean while accumulated moisture and dust can be removed with the front window wiper/washer.
The suspension seat features lumbar support and head rest that provide optimum comfort. Armrests are adjustable and cupped for better arm support.
Hydraulic pilot actuated joystick controls with foot pedal swing for easy operator control of all functions.
A high capacity air conditioning and heater system includes channeled air flow to louvered vents for full coverage of the operator and defrosting/defogging of windows.
The molded console with storage trays eliminates cab clutter. The headliner helps reduce noise in the cab and houses HVAC louvers that allow the operator to adjust air flow. Two 12-volt power points and a factory installed CB mounting bracket, antenna cable, and power harness provide flexibility for additional electric and electronic equipment.
The walk up platform includes skid resistant deck and stair components for safe access. An enlarged doorway provides easy cab entry.
The custom-engineered hydraulic system forms the heart of the C Series. The system is designed for fast cycle times, smooth operation and maximum reliability in delimbing and loading operations.
Designed for continuous, efficient and reliable operation, the loader's axial piston hydraulic pump meets stringent requirements for noise, efficiency, controllability and durability.
The valve system has proven reliability in forestry applications with its fuel efficient negative control system providing precise control of individual functions. Each section is tuned for optimized flow and pressure of the function, therefore increasing machine functionality and fuel efficiency.
Three operating modes allow the operator to tailor the machine's performance to match the job requirements. The “economy” mode provides the best combination of fuel efficiency and performance; an intermediate “run” position provides additional flow capabilities when higher production is required, and a “power” mode allows the full potential of the machine to come on-line to handle large timber and the heaviest delimbing requirements. All of the operating modes provide the best multi-function ability, function response, control and fast cycle times.
The Cat ECM provides best in class diagnostics, operator setup capability, and adjustment of attachment flows.
The hydraulic oil sight gauge makes it easy to know when oil needs to be added. Adding hydraulic oil is fast and easy with the on-board service hose and electric fill pump. Hydraulic oil is pumped through the filtering system and into the tank, maintaining cleanliness requirements.
From log loading to pull through delimbing, a selection of grapple styles are available, including:
TW (tapered wedge) jaw designs for easily grabbing trees from a pile and aggressively gripping trees for delimbing.
SN (straight, narrow) jaw designs for easy log handling in loading and millyard applications.
Grapple jaws are constructed of special high-tensile wear resistant steel. Critical areas of the jaws are reinforced and designed to protect the cylinder rods and hoses.
Cylinder size and jaw configuration provide holding forces for large multi-stem loads as well as the ability to handle single logs.
Rounded jaw tips minimize damage to individual logs.
Heavy-duty rotators include high-pressure swivels for demanding applications. Each head assembly is constructed of high-tensile steel with heavy-duty bearings and hardened gears.
A premium gauge cluster includes LED warning indicators and a digital display which provides information about machine operation, control activation, system diagnostics and operator adjustable settings.
Standard industry relays are replaced by solid state controls in high cycle applications to provide substantially longer service life.
The Delimber/Slasher (DS) package is a complete factory installed timber merchandising system consisting of a knuckleboom loader and grapple, trailer with trailer-mounted delimber and ground saw slasher connections. The structural design on these loaders is proven to provide long life in punishing, pull-through delimbing applications. The package contains either a three-knife CTR 320 or a four-knife CTR 426 pull-through delimber to match application requirements. These delimbers are designed to allow quick, easy loading of trees and produce clean, delimbed stems in a flash. These delimbers also have central lubrication banks and ground level oil fill for quick, easy service. An automatic chain tensioner simplifies maintenance and extends bar and chain life. The delimbing trailers are built with structural reinforcing in critical areas for durability. Non suspension or single point tandem axle suspension is available and all trailers feature hydraulically adjustable landing gear that is adjustable from in-cab controls. This feature allows the operator to quickly position the loader in a proper operating position and make adjustments to maintain a stable base under the delimber.
Cat knuckleboom loaders are known for superior multifunction capability, excellent visibility and heavy-duty booms and structures. Now the Cat C Series knuckleboom loaders feature a new more fuel efficient power system, an upgraded hydraulic system for greater reliability and significantly more lift at full reach than previous models. Like the smaller model, the Cat 579C, now has a right-side operator's cab with a walk-up platform and enlarged doorway for safe access to the cab.
