The 495B is powered by a 173-HP Cummins QSB6.7 Tier 4 diesel engine with SCR aftertreatment.
Hydraulic Control System
The 495B features a pilot-operated control system, in conjunction with IQAN electronic controls, to provide a more natural feel for the operator. The system can be configured as necessary, and maintenance can be performed simply without a specialist.
Load Sensing Hydraulics
Unlike open loop systems that waste fuel, Barko’s efficient load sensing system delivers power only when needed. Load sensing valves and pump deliver excellent metering by matching pressure and flow. Adaptable to most attachments, the system runs cool. Efficient and precise grapple functions reduce operator fatigue.
Multi-functional dual joystick controls are ergonomically designed to provide enhanced comfort and productivity.
Wider, all-welded boom construction with fabricated box type design includes engineered sweeping curves for added strength and increased fatigue resistance.
Rotary manifold allows for 360-degree continuous boom rotation and provides electrical and hydraulic power to the lower frame.
Dual motors and planetary gearboxes produce 44,000 foot-pounds of swing torque, while improving machine balance.
Standard 3,000-pound cast steel counterweight provides extra stability.
Zinc Plated Pins
Extra large zinc plated pins and bolts provide added durability in high-stress areas.
Centralized hydraulic control valves are easily accessible outside cab door.
Bolt-On Cylinder Glands
Bolt-on cylinder glands make on-site service easy, while piston rings extend product life. Cylinders are made of heavy-duty steel tubing, and heavy chrome cylinder rods are heat-treated for added strength.
Centralized turntable greasing system and removable service panels simplify maintenance tasks.
Vibration-isolated “floating cab” provides a smoother ride. Weather sealed, insulated and climate controlled, the cab includes a suspension seat with armrests, foot swing controls and halogen lights.
Digital display provides enhanced monitoring of all machine functions.
Tinted windows, including roof and sliding side windows, provide excellent visibility for safer operation.
120-gallon (454 L) fuel tank capacity allows for longer operating intervals.
Two sets of foldaway stabilizers further contribute to keeping loads steady.
