Benefits & Features
Powertrain
3304 DIT Engine
Cat 3304 DIT engine sets the industry standard for reliability and durability.
Torque Converter
Large, heavy duty torque converter provides torque multiplication which, when combined with the high torque rise of the 3304, provides excellent skidding power.
Four-Speed Transmission
Four-speed transmission easily matches power to the load size and ground conditions.
Differential Locks
Hydraulically engaged differential locks significantly expand the operating range of the 515.
Flexibility
Balance
Excellent skidder balance, plus the powerful mechanically driven, heavy duty winch provides outstanding 515 cable skidder performance.
Tire Options
Expanded tire options allow the 515 to maintain skidding performance in a wide range of ground conditions.
Axle
Robust Components
Robust components provide outstanding reliability and durability.
Oil Sump
Full axle length oil sump provides excellent lubrication and heat rejection for long life.
Final Drives
Heavy duty inboard final drives and brakes are protected from the harshness of logging environment.
Front Axle Cradle
Front axle cradle provides a significant performance enhancement:
Hydraulics
Load Sensing Hydraulics
Load sensing hydraulics utilize a load sensing, variable displacement pump and pressure compensating system.
Reduced Pump Flow Requirements
Reduce engine horsepower demand when not needed for hydraulic output.
The Auto-Grab Feature
The Auto-Grab feature engineered by Caterpillar constantly monitors and adjusts tong pressure as needed to securely hold grapple loads while skidding.
Hydraulic Retrieval Device
Hydraulic retrieval device utilizes the power of the Caterpillar variable displacement pump.
Operator Station
Easy Operation
Modular ROPS/FOPS cab is resiliently mounted to the frame.
Structures
Hitch Pin
New wider hitch pin spread significantly reduces horizontal loading on hinge pins and hinge pin bearings for improved pin and bearing life.
Rear Frame
Robust rear frame provides the platform to support the dual function grapple arch or cable arch configurations.
Front Frame
The front frame is designed with higher clearance to accommodate the front axle cradle mounts.
Decking Blade
Decking blade with fabricated, box-section steel arms mounts directly to the mainframe for superior strength.
Serviceability
Less Service Time
Built-in servicing ease.
Ground Level Access
Ground-level access provides convenient servicing to most filters and lube points.
Pre-Cleaner
Centrifugal pre-cleaner removes large debris before it reaches the internal air cleaner to provide significant engine protection.
S•O•S and Coolant Sampling Valves
S•O•S and Coolant Sampling Valves provide a fast, convenient means of obtaining fluid samples and improve analysis reliability.
Radial Seal Air Filters
New radial seal air filters are easy to change, reducing air filter maintenance times.
Turbocharger
The relocated turbocharger provides easy access to the air cleaner and allows the cab compartment to be sealed from dust and debris.
Spin-on Oil Filters
Spin-on fuel and engine oil filters save changing time.
Pressure Taps
Pressure taps are conveniently located.
Electrical System
24-volt electrical system delivers increased electrical power for engine cranking, lights, and engine diagnostics.
