JLG G5-18A Specifications
| Basic Information |
The JLG G5-18A telehandler is a compact rough-terrain material handler engineered for construction, industrial, and maintenance applications requiring strong lifting ability in confined spaces.
With a rated capacity of 5,500 lb (2,495 kg) and a maximum lift height of 18 ft 4 in (5.6 m), the G5-18A is tailored for contractors and fleet owners who need maneuverability, reliability, and easy transportability.
Highly valued in residential and light commercial construction, it excels at handling palletized loads, placing materials to elevated platforms, and performing precise load-handling tasks inside restricted job sites.
Equipped with a durable Deutz diesel engine, hydrostatic transmission, versatile steering modes, and a compact frame, the G5-18A balances performance, efficiency, and service simplicity.
| Engine Specs |
Engine Make and Model: Deutz TD 2.9 L4
Fuel: Diesel
Cylinders: 4
Displacement: 177 cu in (2.9 L)
Gross Power: 74 hp (55 kW)
Maximum Torque: 192 lb-ft (260 Nm) @ 1800 rpm
Fuel Tank Capacity: 24 gal (91 L)
The Deutz TD 2.9 L4 engine is designed for compact equipment applications. Its
torque distribution supports hydrostatic drive demands and smooth boom
operation. The engine features a liquid-cooled system, direct injection, and a
compact turbocharger.
A dry air cleaner with restriction indicator ensures dust protection. Maintenance includes periodic oil changes, fuel filter replacement, and cooling system inspection.
| Drive Train |
Transmission
Type: Hydrostatic
Speed: Infinitely variable
Top travel speed (4-speed hydrostatic mode): 15 mph (25 km/h)
Provides smooth modulation for forward and reverse travel, enabling precise
control during load placement.
Axles
Front Axle: High-bias limited slip differential
Rear Axle: Planetary axle with oscillation for stability
Both axles are built to withstand rough terrain and heavy-duty cycles.
Brakes
Service Brakes: Inboard wet-disc brakes on front axle
Parking Brake: Wet-disc spring-applied hydraulic-release system
Wet-disc braking technology ensures long life and strong braking power in mud,
dust, and debris.
| Electrical System |
System Voltage: 12V
Alternator Output: Standard heavy-duty charging system
Battery Capacity: Sufficient for cold starts and auxiliary electrical systems.
Instrumentation:
- Hourmeter
- Steering mode indicator
- Engine coolant temperature
- Fuel gauge
- Alternator gauge
- Parking brake indicator
- Travel speed readout
- Engine speed indicator
- Vehicle and engine system warnings, including fault codes
The electrical system includes protected wiring harness routing, sealed
connectors, and weather-resistant components for harsh job-site environments.
| Wheels and Tires |
Drive Configuration: 4-wheel drive (4WD)
Tires
Standard: 12x16.5 Pneumatic
Optional: 14 x 17.5 Pneumatic
Optional: 12 x 16.5 Foam-filled
Optional: 14 x 17.5 Foam-filled
Optional: 33 x 12 Solid
The chassis is a compact, welded-steel structure designed for rigidity and
durability. The short wheelbase and narrow width support maneuverability in
tight work areas. Skid-resistant steps and handholds support safe machine entry.
The G5-18A features operator-selectable
steering modes:
- 4-wheel circle steering
- 4-wheel crab steering
- 2-wheel front steering
Turning Radius (outside): 127 in (3.2 m).
Steering is hydraulic with responsive modulation for tight maneuvering. Manual
backup steering ensures machine control in case of hydraulic loss.
| Hydraulic System |
Hydraulic system
type:
- Single-section gear pump
- Used for boom lift, boom extend/retract, tilt, sway (if equipped), and
auxiliary attachment functions
- Auxiliary hydraulics support all attachment cylinders.
- Hydraulic Oil Capacity: 24 gal (91 L)
Boom hydraulic performance:
Lift Speed (retracted): Up 6.8 sec / Down 4.6 sec
Boom Speed: Extend 6.7 sec / Retract 3.8 sec
Holding valves are installed on major boom functions to prevent unintentional
drop or cylinder retraction.
