535B^Non-Current

3126 DITA Engine

The Cat 3126 delivers reliable power with low emissions, excellent fuel economy, and traditional Caterpillar durability.

Torque Converter

The large, heavy-duty torque converter with a lockup clutch is matched to the Cat 3126 engine for excellent rimpull, speed and improved skidding performance.

Five-Speed Transmission

The Cat powershift countershaft transmission easily matches engine power to the load size and ground conditions.
• Gears 1 and 2 provide industry leading pull capability for heavy load and steep grade applications.
• Gear 3 is for lighter loads and higher speed operations
• Gears 4 and 5 provide excellent empty return speeds to maximize productivity.

Differential Locks

Hydraulically engaged differential locks in both axles significantly expand the operating range of the 535B. They reduce tire slip during turns, improve flotation, and reduce tire wear. In addition, they enhance maneuverability by improving traction and allowing a tighter turning radius.

Load Sensing Hydraulics

A load sensing variable displacement pump and pressure compensating system continually monitor hydraulic power requirements, and provide hydraulic power based on demand.

Auto-Grab Feature

Constantly monitors and adjusts tong pressure as needed to securely hold loads in the grapple. Like the load sensing hydraulic system, Auto-Grab places demand on engine horsepower only when the system senses a change in the load that requires an increase in tong pressure. It is easily activated on demand by the tong close switch located on the right hand control lever. Tractor operation is much easier, constant tong pressure is maintained, and operating costs are reduced through greater fuel efficiency and less time spent re-gripping slipped loads.

Winch

The 535B uses a high capacity winch with four-function control. This self-contained unit has a separate oil pump using winch sump oil for control, and to cool and lubricate the winch.

Cat Hoses

Caterpillar hose technology allows high pressures for maximum power and reduced downtime, and intelligent routing minimizes exposure to damage.

Steering

Fully hydraulic control. Meets the following standards: SAE J1511/ISO 5010 FEB94, ISO 5010-1992

Cradled Front Axle

Exclusive to Caterpillar wheel skidders, the cradled front axle with a high pivot center acts as a working counterweight, and delivers enhanced performance and operator comfort. It provides excellent fore-aft stability for large grapples and the dual-function arch. Heavy-duty trunnion bearings assure durable, reliable operation. The 15 degree oscillation absorbs minor shock loads, isolating the cab from axle movement for a smoother ride.

Final Drives

Heavy-duty inboard final drives are protected from the harsh logging environment, and use splash oil lubrication and cooling. This configuration makes wheel and tire removal and installation easier.

Brake Components

Brake components are housed inside the axles, protecting them from dirt, dust and wet ground conditions. Inboard brakes allow for splash lubrication and cooling, are virtually maintenance free, and provide reliable brake performance in the most demanding logging applications.

Oil Sump

Full axle-length oil sump provides excellent lubrication and heat rejection for long component life. All components housed in the axle are splash lubricated, and outboard bearings are maintenance free. • Large oil capacity delivers excellent heat rejection, ensuring proper lubrication

Differential Locks

Differential locks provide added traction in poor ground conditions. On-the-go engagement / disengagement allows operator to maintain production without stopping.

Wheel Options

The 535B axle is capable of single or dual wheels. Dual (using 30.5 x 32 inner and 24.5 outer) or flotation tires increase flotation in wet, sloppy underfoot conditions, and improve stability on grades with large loads.

Box-Section Construction

The 535B frames use resilient box section construction that sets the industry standard for reliability and durability.

Front Frame

The front frame is designed with higher clearance to accommodate the front axle cradle mounts, and lower blade pivot mounting position.

Rear Frame

Tough rear frame provides the platform to support the grapple arch or cable arch configurations.

Ground Clearance

Maximized ground clearance improves maneuverability and avoids damage. Full belly guards protect all undercarriage components.

Decking Blade

Fabricated, box-section steel arms mount directly to the mainframe for superior strength.

Hitch

The bottom hitch has a double tapered roller bearing for improved load distribution, which reduces flexing stress and maintains tight joints.

Arches

The 535B dual-function arch and the cable arch are designed and tested to exceed durability requirements.

Grapples

Durable, high capacity sorting and bunching grapples are matched to machine size and horsepower for optimum performance.

Winch

The 535B winch attachment delivers the power and durability ideal for log truck towing, self-retrieval and log skidding.

ROPS / FOPS

Roll-Over Protection and Falling Object Protection guards offer protection to the operator and the machine. Meets standards: ISO 8082 2003, ISO 8083 1989, and ISO 8084 2003

Balance

Long front and rear frames and a low center of mass create excellent skidder balance. The powerful mechanically driven, heavy-duty winch provides outstanding grapple or cable skidder performance.

Torque Converter

The heavy duty lockup torque converter offers the advantages of a direct drive transmission (speed and efficiency), with the ease of operating a torque converter drive (meaning less shifting). A computer senses load conditions and automatically switches from torque converter drive to direct drive for the highest possible operating speed.

Cradle Oscillation

For the ultimate in skidder flexibility the 535B is available with cradle oscillation, which isolates the cab from axle movement.

Wheelbase

The 535B skidder has a wider, longer wheelbase to handle dual-function arch and large capacity bunching grapples.

Dual-Function Arch

Offers variable reach and large grapple capacities, well suited for large bundles of small stems.

Cat Continuous Rotation Grapples

With 360° rotation the Cat continuous rotation (CCR) grapples can easily get into position to gather stems. Grapple repositioning is reduced, saving valuable time and increasing production.

Cable Arch

Allows outstanding line skidding performance with a two position adjustable height fairlead to match site conditions.

Decking Blade

Efficiently clears landings and roads, and maintains stockpiles.

Tire Options

Expanded tire options allow the 535B to maintain outstanding skidding performance in a wide range of ground conditions.

Dual-Capable

The standard axle on the 535B is capable of using dual or flotation tires. Dual wheels increase flotation in poor underfoot conditions, and improve stability, especially when hauling large loads on a grade.

Light Options

Expanded light options allow the 545 to maintain skidding performance and productivity at any hour.

Built-in Servicing Ease

Caterpillar uses intelligent engineering to make regular maintenance procedures quick and simple. Easy access to daily service points increases the likelihood that maintenance will be done, extending machine service life and lowering overall operating costs. In addition, less service time means more working time and greater productivity.

Ground Level Access

Most filters and lube points are accessible from the ground. Remote lubrication points make daily attention to hard-to-reach joints easy.

Centrifugal Pre-Cleaner

Centrifugal pre-cleaner removes large debris before it reaches the internal air cleaner to provide significant engine protection.

S•O•SSM and Coolant Sampling Valves

Provide a fast, convenient means of obtaining uncontaminated fluid samples, which improves analysis reliability.

Radial Seal Air Filters

Hand access makes them easy to change, reducing air filter maintenance times.

Spin-on Oil Filters

Spin-on filters for fuel and oil systems reduce changing time, and help assure clean, tight seals.

Pressure Taps

Conveniently located to provide easy access to hydraulic system pressure measurements.

Ecology Drains

Located on the axle and hydraulic tank to make regular maintenance easier, and protect the environment from accidental oil spills.

Electrical System

24-volt electrical system delivers plenty of electrical power for engine cranking, lights, and engine diagnostics. Wiring circuits are color coded, numbered and protected by circuit breakers.
