BRAKE SYSTEM


 

A simple and reliable brake system with few moving parts. Selfadjusting oil circulation cooled wet disc brakes give long service intervals. Brake wear indicator and brake test in Contronic II are included in the brake system. Service brakes: Volvo, dual-circuit system with nitrogencharged accumulators for dead engine braking. Fully hydraulically operated, enclosed internal oil circulation-cooled, outboard mounted disc brakes. Transmission declutch during braking can be preselected with a switch on the instrument panel. Brake performance test in the Contronic II system. Parking brake: Enclosed wet multi-disc brake built into the transmission. Spring-loaded application. Electro-hydraulic release via a switch on the instrument panel. Automatically applied when the key is turned off. Secondary brake: Either of the service brake circuits or the parking brake fullfills ISO/SAE safety requirements. Standards: The brake system complies with the requirements of ISO 3450, SAE J1473

OPERATIONAL DATA VOLVO L120D

BUCKET SELECTION CHART


The choice of bucket is determined by the density of the material and the bucket fill factor. The TP-linkage uses a very open bucket design, has very good roll back in all positions and fills the bucket very well. This means that the actual volume carried is often larger than the rated capacity of the bucket. Bucket fill factors for different materials and how they affect the actual bucket volume are shown in the table. Example: Sand and gravel. Fill factor ~105%. Density 1,65 ton/m3. Result: The 3,3 m3 bucket carries 3,5 m3. For optimum stability always consult the bucket selection chart.

STEERING SYSTEM


 

Easily operated steering results in fast work cycles. The powerefficient system results in good fuel economy, good directional stability and a smooth ride. Steering system: Load-sensing hydrostatic articulated steering with power amplification. System supply: The steering system is supplied by a separate steering pump. Pump: Double variable-flow axial piston pump. Cylinders: Two double-acting cylinders.

CAB


 

Care Cab II with wide door opening and easy entry. Inside of cab lined with noise-absorbent materials. Noise and vibration suppressing suspension. Good all-round visibility through large glass areas. Curved front windshield of greentinted glass. Ergonomically positioned controls and instruments permit a comfortable operating position. Instrumentation: All important information is centrally located in the operator's field of vision. Display for Contronic II monitoring system in center console on dashboard. Heater and defroster: Heater coil with filtered fresh air and fan with four speeds. Defroster vents for all windows. Operator's seat: Operator's seat with adjustable suspension and retractable seatbelt. The seat is mounted on a bracket on the rear cab wall. The forces from the retractable seatbelt are absorbed by the seat rails. Standards: The cab is tested and approved according to ROPS (ISO/CD 3471, SAE J1040), FOPS (ISO 3449, SAE J231). The cab meets with requirements according to ISO 6055 ("protective roof for high-lift vehicles") and SAE J386 ("Operator Restraint System").

HYDRAULIC SYSTEM


Open center hydraulic system with efficient, high capacity vane pumps allows precision control and quick movements at low rpm. Pump: Vane pump fitted to a power take-off on the transmission. The pilot system is supplied from a combined pilot/brake pump which is mounted in series with the steering pump. Valve: Double-acting 3-spool valve. The control valve is actuated by a 3-spool pilot valve. Lift function: The valve has four functions: raise, hold, lower and float. Inductive/magnetic automatic boom kickout can be switched on and off and is adjustable to any position between maximum reach and full lift height. Tilt function: The valve has three functions: rollback, hold and dump. Inductive/magnetic automatic bucket positioner that can be switched on and off. Cylinders: Double-acting Filter:
