JLG G10-43A Specifications
The JLG G10-43A telehandler is a rugged, high-capacity
rough-terrain material-handling machine designed for demanding construction,
industrial, and mining applications. Positioned in the 10,000-lb (4,536-kg)
capacity class, the G10-43A combines powerful hydraulic performance, excellent
boom reach, and dependable structural durability.
Its maximum lift height of 43 ft (13.1 m) and
maximum forward reach of 30 ft 6 in (9.3 m) allow operators to place
palletized loads, structural components, masonry materials, and bulk
construction supplies with precision and confidence.
The G10-43A features a Cummins QSB3.3L diesel engine, a 4-speed
powershift transmission, heavy-duty planetary axles, and a load-sensing
hydraulic system engineered for smooth multi-function control. The
machine’s operator station emphasizes visibility, ergonomic layout,
safety indicators, and intuitive operation.
Multi-mode steering, standard on
SkyTrak-derived JLG telehandlers, provides maneuverability in congested
job sites while maintaining stability during high-reach operations. With
outstanding reliability and simplified maintenance access, the G10-43A
is widely used by general contractors, steel erectors, masonry crews,
and equipment rental companies.
The G10-43A is powered by the Cummins QSB3.3L diesel
engine, a turbocharged industrial powerplant known for strong torque and clean
Tier-compliant performance.
Engine specifications:
- Make and Model: Cummins QSB3.3L
- Displacement: 202 cu in (3.3 L)
- Number of cylinders: 4
- Fuel type: No. 2 Diesel
- Operating cycle: 4-stroke
- Rated speed: 2400 rpm
- Maximum gross power: 100 hp (75 kW)
- Maximum torque @ 1500 rpm: 306 lb-ft (414 Nm)
- Fuel tank capacity: 38 gal (144 L)
The engine includes a two-stage dry air cleaner with centrifugal pre-cleaner, a
continuous dust-ejector system, and a service-indicator gauge. Engine filtration
incorporates a replaceable fuel filter/water separator and a full-flow oil
filter. The cooling system uses a heavy-duty radiator designed for continuous
high-load operation.
The QSB3.3L is engineered for reliability in telehandler applications, where
engine torque directly supports hydraulic pump load and tractive effort. Its
broad torque band ensures responsive lift and travel characteristics even at
moderate throttle settings.
The G10-43A uses a
torque-converter-based powershift transmission:
- Type: Powershift
- Forward gears: 4
- Reverse gears: 3
- Directional and gear selection: Single-lever steering-column-mounted control
- Neutral start: Requires park brake engagement
- Maximum travel speed: 20 mph (32 kph)
The 4-speed powershift transmission provides strong low-gear tractive effort for
pushing into material piles or climbing grades, while higher gears enable
eicient travel between work areas.
Heavy-duty planetary axles support rough
terrain and full-load operation:
- Trunnion-mounted steer axles
- 55° steering angle
- Planetary hubs for torque distribution
- High-bias limited-slip front differential
- Full-time 4-wheel drive
These axles provide excellent durability, shock absorption, and traction
capability.
The machine uses wet-disc braking for
dependable performance in harsh conditions:
- Service brakes: Inboard wet-disc, front and rear
- Parking brake: Wet disc, spring-applied hydraulic-release, located on front
axle
- Parking brake indicator: Dashboard warning light
Wet-disc brakes resist fading, require minimal adjustment, and withstand mud,
dust, and debris.
Electrical system
components include:
- Voltage: 12V
- Alternator: 63 amp
- Battery: 810 CCA at 0°F
Operator instrumentation:
- Voltmeter
- Hourmeter
- Oil pressure gauge
- Fuel gauge
- Engine water-temperature gauge
- System status indicators
The G10-43A provides operator-platform protection for all gauges via an acrylic
shield. The electrical architecture supports optional accessories including
auxiliary electrics, cab lighting, road lights, and climate-control components.
Drive System
- Full-time 4-wheel drive
- Planetary front and rear axles
- Heavy-duty welded steel frame
The chassis is engineered for long-term endurance, resisting torsional stress
during side-load operations and uneven terrain conditions common in construction
environments.
Tire specifications:
- Standard tire size: 400/75-28
- Optional tires: Foam-filled, solid construction tires
Larger tire dimensions improve flotation, stability, and shock absorption on
rugged terrain.
Steering modes (operator selectable):
- 4-wheel circle steering
- 4-wheel crab steering
- 2-wheel front steering
Power steering with manual backup ensures safe, smooth directional control even
in the event of hydraulic pressure loss.
Hydraulic system
include:
- Load-sense piston pump
- Auxiliary hydraulics available for attachments
- Holding valves on lift, crowd, tilt, telescope, and sway cylinders
- Implement hydraulic system capacity: 40 gal (151.4 L)
Boom hydraulic performance:
- Lift speed (boom retracted): Up 11 sec / Down 11 sec
- Boom extension speed: 15 sec
- Boom retraction speed: 16 sec
Load-holding valves are designed to prevent cylinder drift and secure suspended
loads if a hydraulic hose fails. Filtration includes a fine 8-micron filter and
suction strainer.
