The Cat 3126 delivers reliable power with low emissions, excellent fuel economy, and traditional Caterpillar durability.
The large, heavy-duty torque converter with a lockup clutch is matched to the Cat 3126 engine for excellent rimpull and improved skidding performance.
The Caterpillar powershift countershaft transmission easily matches engine power to the load size and ground conditions. Gear 1 provides industry leading rimpull capability for heavy load applications, gears 2, 3 and 4 are for lighter loads and higher speed operations, while gear 5 provides excellent empty return speeds.
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.
A load sensing variable displacement pump and pressure compensating system continually monitor hydraulic power requirements, and provide hydraulic power based on demand.
Constantly monitors tong pressure and adjusts as needed to securely hold grapple loads. 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 or decrease 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.
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.
Caterpillar hose technology allows high pressures for maximum power and reduced downtime, and intelligent routing minimizes exposure to damage.
Fully hydraulic control. Meets the following standards: SAE J1511 OCT90, ISO 5010-1992.
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.
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 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.
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 provide added traction in poor ground conditions. On-the-go engagement / disengagement allows operator to maintain production without stopping.
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.
The 535B frames use resilient box section construction that sets the industry standard for reliability and durability.
The front frame is designed with higher clearance to accommodate the front axle cradle mounts, and lower blade pivot mounting position.
Tough rear frame provides the platform to support the grapple arch or cable arch configurations.
Maximized ground clearance improves maneuverability and avoids damage. Full belly guards protect all undercarriage components.
Fabricated, box-section steel arms mount directly to the mainframe for superior strength.
The bottom hitch is double-tapered for improved weight distribution, which reduces flexing stress and maintains tight joints.
The 535B dual-function arch and the cable arch are designed and tested to exceed durability requirements.
Durable, high capacity sorting or bunching grapples are matched to machine size and horsepower for optimum performance.
The 535B winch attachment delivers the power and durability ideal for log truck towing, self-retrieval and log skidding.
Roll-Over Protection and Falling Object Protection guards offer protection to the operator and the machine.
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.
The heavy duty lock-up torque converter offers two drive options: direct drive, the only option in many skidders, delivers excellent skidding power and speed; while torque converter drive provides torque multiplication and speed control, which reduces the need for frequent transmission gear changes.
The 535B skidder has a wider, longer wheelbase to handle dual-function arch and large capacity bunching grapples.
Expanded tire options allow the 535B to maintain outstanding skidding performance in a wide range of ground conditions.
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.
The 535B is available with either a dual-function arch for grapples, or the cable arch, and a decking blade to match the machine to the application.
The 535B work station incorporates years of design innovations to reduce operator fatigue and increase productivity.
The comfortable 535B operator environment uses ergonomically designed and placed machine controls to reduce fatigue and increase productivity.
The 535B uses conveniently located and easy-to-see gauges and displays to make monitoring machine systems as simple as possible.
Pre-wired for an entertainment radio, with two speakers, an antenna and standard built-in 24-to-12-volt converter. The machine is fitted with on-off key switch engine operation.
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.
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 removes large debris before it reaches the internal air cleaner to provide significant engine protection.
Provide a fast, convenient means of obtaining uncontaminated fluid samples, which improves analysis reliability.
Hand access makes them easy to change, reducing air filter maintenance times.
Offer protection to critical components, but are easily removable for fast service access. Removable floor plates and side plate allow access to components under the cab.
The relocated turbocharger provides easy access to the air cleaner and allows the cab compartment to be sealed from dust and debris.
Spin-on filters for fuel and oil systems reduce changing time, and help assure clean, tight seals.
Conveniently located to provide easy access to hydraulic system pressure measurements.
Located on the axle and transmission to make regular maintenance easier, and protect the environment from accidental oil spills.
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.
The Caterpillar Monitoring System continuously checks all critical machine functions and components, and helps locate faults quickly for faster repair.
