JLG 3509 Specifications
The JLG 3509 telehandler is a compact, versatile, and
rugged rough-terrain machine designed to deliver dependable performance in
construction, industrial, agricultural, and material-handling environments. With
a maximum lift capacity of 3,500 kg and a lift height of 9.0 metres, the 3509
occupies a useful mid-range category, balancing maneuverability with working
power.
Its compact wheelbase, strong chassis, and
efficient hydraulic system allow operators to handle palletised loads,
general materials, bulk goods, and attachments in tight job-site
conditions where larger telehandlers may be restricted.
Powered by a Perkins 1104D-44T turbo-diesel engine and equipped with a
powershift transmission, the 3509 offers predictable torque delivery and
reliable travel characteristics across varying terrain. The machine
features multi-mode steering, four-wheel drive, and a rigid structural
platform that provides stability during elevated lifting.
With a Clear View operator cab, audio-visual
load-stability indication, and a robust quick-switch coupler system, the
JLG 3509 is engineered to simplify daily operations and reduce downtime.
This telehandler exemplifies the JLG philosophy of building durable,
easily serviceable equipment suitable for demanding, daily use.
The JLG 3509 is powered by a Perkins 1104D-44T diesel
engine engineered to deliver consistent torque, fuel efficiency, and long
service life. The engine’s four-cylinder, liquid-cooled, turbocharged
configuration ensures strong low-end power essential for lifting and hydraulic
work.
Engine specifications:
- Model: Perkins 1104D-44T
- Power rating: 74.5 kW at 2200 rpm
- Displacement: 4.4 L
- Turbocharged, liquid-cooled
- Emissions: EPA Tier 3 / EEC Stage IIIA compliant
- Fuel tank capacity: 140 L
- Engine oil capacity: 7.9 L
- Coolant capacity: 19.7 L
This engine is known for its simple maintenance structure, mechanical
durability, and strong torque performance under load. Routine service includes
air filtration inspection, oil changes, coolant monitoring, and ensuring correct
fuel-system cleanliness.
The 3509 telehandler is equipped with a heavy-duty
powershift transmission.
Transmission
- Transmission configuration: 4 forward gears / 3 reverse gears
- Optional transmission: 3 forward / 3 reverse
- Drive: 4x4
Powershift gearing provides smooth direction changes and supports reliable
torque transfer for climbing, loading, and site maneuvering.
Axles
- Four-wheel drive with planetary axles
- Engineered for rough-terrain stability and traction
Brakes
- Wet multi-disc parking brake system
- Hydraulic service brakes
Wet-disc braking provides excellent lifespan and consistent performance in muddy
or dusty job-site environments.
The electrical system is designed around reliability
and environmental protection. Operators benefit from a clear instrument layout,
integrated warning indicators, and audio-visual overload notification.
Key electrical characteristics include:
- Standard 12 V system
- Load stability indicator
- Full operator instrumentation (fuel, temperature, oil pressure, warning
lights)
- Clear View cab lighting and optional external work lights
Drive System
- Full-time four-wheel drive
- Heavy-duty welded steel frame engineered for torsional strength
Tires
- Standard: Industrial pneumatic tires sized for off-road traction and stability
These tires provide a strong balance between load-bearing performance and ground
contact stability.
The JLG 3509 features a three-mode steering system designed for maneuverability
in a range of environments.
Steering modes:
- Front-wheel steer
- Coordinated steer (4-wheel)
- Crab steer
Turning radius:
- Over tyres: 3.80 m
- At fork: 5.02 m
This steering configuration allows operators to navigate restricted or uneven
spaces with ease, positioning loads precisely.
The hydraulic system provides the smooth, powerful
motion required for lifting and material placement.
Hydraulic specifications:
- Pump type: Load-sensing piston pump
- Maximum flow: 132 L/min
- Hydraulic reservoir capacity: 160 L
The load-sensing design adapts flow to demand, improving fuel efficiency and
reducing system heat generation. Hydraulic functions include lift, crowd,
extend/retract, and auxiliary circuits for attachments.
