G710B Volvo G710B Specifications & Technical Data (2002—2005)

Cab & Controls

All controls are located in a 90° arc forward and to the right of the operator. The enclosed cab has a fully adjustable, cloth-covered suspension seat as standard and comes with a 3” (76 mm) seat belt. Located forward of the operator are the engine oil pressure, coolant temperature, and fuel level gauges, along with the transmission gear indicator and a multi-function electronic monitoring display. In the fully adjustable steering pedestal, you will find the following switches: differential lock/unlock, hazard lights, combination turn signal, horn, and high beam headlight. Heater and wiper/washer controls (if equipped), lighting, and accessory switches are grouped in the operator’s right-hand console. This console contains the ignition key and provides access to the circuit breaker and fuse panel. An accelerator/decelerator foot pedal and slider-type hand throttle are standard equipment. Additionally, outside mounted rear view mirrors (left and right) and a convex interior mirror are standard. Interior operator noise levels average 75 dB(A) per ISO 6394 (enclosed cab).

Transmission

Fully sequential, direct drive, powershift transmission. Engine cannot be started if transmission is in gear. Single lever “Smart Shifter” electronic transmission controller provides self-diagnostic tests. The highly mounted, multi-disc master clutch is oil cooled and lubricated for long life. Ground speeds at 2200 RPM with standard tires.

Brakes

Service Brakes: Foot operated. Brake pedal: hydraulically actuated, wet multiple disc service brakes located at the 4 tandem drive wheels are self-adjusting, fully sealed and maintenance free. System features crossover dual braking circuits for uniform braking on both sides of the grader. Includes reserve power assist and operator warning system (visual and audible). Parking Brake Spring applied hydraulic release independent, disc type parking brake on transmission output shaft and effective on all 4 tandem drive wheels. Includes visual and audible operator warning system for parking brake on, transmission in gear condition. Transmission will not engage with park brake on. Braking system complies to SAE Recommended Practice J1473 OCT. 90 and J1152 APR. 80; ISO 3450-1993-01-28. Volvo uses asbestos free brake components.

Circle Drive

The Volvo dual cylinder Circle Drive System uses direct acting hydraulic power for exceptional turning and holding capability under full load. The Circle Drive System uses hardened drive pinions and is protected against impact damage by an overload relief valve as standard equipment.

Load Sensing Hydraulics

Closed Center Hydraulic System senses load requirements and maintains system pressure at 350 psi (24 Bar) above the load pressure. System features industry standard control arrangement complete with low effort, feathering type short throw levers located on a fully adjustable steering pedestal. System incorporates lock valves to prevent cylinder drift under load in the following circuits: blade lift, moldboard tilt, circle shift, wheel lean, circle turn and articulation. Hydraulic system features include axial piston pump, pressure and flow compensated, variable displacement with high output for smooth multi-functioning. The pump drive shaft is equipped with Perma lubrication.

Differential / Final drive

Single reduction final drive with an operator controlled lock/unlock differential. Rear axles are induction hardened, supported on double row spherical roller bearings.

Steering

Hydrostatic power front wheel steering incorporating two steering cylinders. Meets SAE J1511 OCT. 90 with optional secondary steering. Minimum turning radius using front axle steering, articulation, wheel lean and unlocked differential 25'5" (7.747 m). Steering arc 72°. Frame articulation angle 22°. Articulation lock standard.

Articulation

Twin 4.5” (114 mm) hydraulic cylinders articulate the frame 22° right and left. Anti-drift lock valve ensures stable operation.

Drawbar

Fully welded box section. Narrow “T” design permits optimum visibility to the work area. Drawbar ball stud provides an adjustment to compensate for different tire sizes. Blade lift cylinder anchor has a straddle mount on the drawbar to provide maximum strength and support.
