Manufacturer: Liebherr Model: L538 Year: 2010 Notes: Wheel loader Operating hours: 8,435 h. Rear differential requires repair. Engine ·Diesel engine: D 934 S A6 ·Construction type: Water-cooled 4-cylinder engine, exhaust gas turbocharger, and charge air cooling (intake air) ·Rated power (ISO 9249): 105 kW at 2,000 rpm ·Maximum torque: 770 Nm at 1,000–1,300 rpm ·Displacement: 6.36 liters ·Bore/Stroke: 122/136 mm ·Air filtration system: Dry air filter with main and backup elements, pre-separator, maintenance indicator on LCD display Electrical system ·Operating voltage: 24 V ·Battery: 2 × 135 Ah / 12 V ·Alternator: Three-phase 28 V / 80 A ·Starter motor: 24 V / 5.4 kW ·Emissions: Exhaust emissions are below the Tier 3A/Tier 3 limit values. Travel mechanism ·Drive: Hydrostatic, continuously variable ·Type: Variable-displacement hydraulic pumps and two closed-loop hydraulic motors with transfer case. Forward and reverse motion is reversed by changing the direction of the travel pump’s flow. ·Filtration: Suction filter for the closed circuit ·Control: Via throttle and inch pedal. The inch pedal allows for stepless control of traction and speed even when the engine is at maximum RPM. The Liebherr joystick is used to select forward/reverse and for attachment and bucket movements. ·Travel speeds: oStage 1: 0 - 6.0 km/h oStage A1-2: 0 - 16.0 km/h oStage A1-3: 0 - 40.0 km/h (Speeds valid for the machine’s standard tires) Axles ·Traction: Four-wheel drive ·Front axle: Fixed ·Rear axle: Oscillating (pendulum) with a 6° angle on each side; clears obstacles up to 470 mm high while keeping all 4 wheels in contact with the ground ·Differentials: Self-locking with a 45% locking value, engaging automatically on both axles ·Axle transmission: Planetary gearboxes in the wheel hubs ·Track width: 1,900 mm for all tire types Brakes · Wear-free service brake: Self-retaining hydrostatic drive of the travel system acting on all 4 wheels and, additionally, hydraulic brake via pump accumulator, with wet disc (lamellar) brakes on the wheel hubs. Two independent braking circuits. ·Parking brake: Electro-hydraulic actuation system on the axle differential ·Standard: The braking system complies with EC 71/320. Steering ·Design: Oscillating central articulation with damping elements ·Articulation angle: 40° (on each side) ·Oscillation angle: 6° (on each side) ·Maximum working pressure: 230 bar ·Emergency steering: Electro-hydraulic emergency steering system Operator cab ·Construction: ROPS-FOPS cab mounted on elastic silent blocks in the rear section, with sound insulation. Door with optional sliding window (180° opening angle), right-hand tilting window that opens, standard green-tinted safety glass front windshield, one-piece side windows made of gray-tinted safety glass, adjustable steering column and standard control levers/controls, rear window with defroster. ·ROPS (rollover) protection: per DIN/ISO 3.471 / EN 474-3 ·FOPS (falling objects) protection: per DIN/ISO 3.449 / EN 474-1 ·Operator seat: 6-way adjustable, cushioning and suspension adjustable to operator weight ·Heating and ventilation: Cab with 4-level air control, coolant-based heating, defrosting, and air conditioning with electronic control valve, plus electronic recirculation/outside air control. Filter system with pre-filter, exterior and interior air filters, easy to replace. Air conditioning standard; automatic climate control optional. Noise emission ·ISO 6396: LpA (in the operator’s cab) = 69 dB(A) ·2000/14/EC: LWA (external) = 102 dB(A) Fill capacities ·Fuel tank: 170 l ·Diesel engine (with filter change): 29 l ·Transfer case: 3.8 l ·Front axle / wheel hub: 16.3 / 2.6 l ·Rear axle / wheel hub: 15 / 2.6 l ·Hydraulic tank: 110 l ·Complete hydraulic system: 180 l Working equipment ·Kinematics: Powerful Z-kinematics with a tilt cylinder; hydraulic quick coupler (optional) ·Bearings: Sealed ·Working cycle at rated load: oLift: 5.9 s oUnload/Dump: 1.6 s oLower (empty): 4.0 s Service hydraulics ·Construction: Variable “Load-Sensing” axial piston pump with power control and pressure cut-off in the valve block ·Cooling: Hydraulic fluid cooling via thermostat-controlled fan and radiator ·Filtration: Return filter in the hydraulic tank ·Control: Joystick control, hydraulic pre-control ·Lifting circuit: Up, neutral, down. Floating control via Liebherr joystick with interlock; automatic disengagement of lift movement; optional automatic load-limiting circuit ·Bucket circuit: Fill, neutral, dump. Automatic bucket return ·Maximum flow rate: 140 l/min ·Maximum working pressure: 330 bar
