JLG 943 Specifications
The JLG 943 telehandler is a high-capacity,
rough-terrain telescopic handler engineered to deliver exceptional lifting
capability, extended reach, and dependable performance in demanding
construction, industrial, agricultural, and infrastructure sectors. With a rated
lift capacity of 9,000 lb (4,082 kg), a maximum lift height of 43 ft (13.1 m),
and a forward reach of 30 ft 5 in (9.3 m), the 943 represents one of JLG’s most
capable mid-frame telehandlers.
Its Cummins Tier 4 Final engine, advanced
load-sensing hydraulics, and multi-mode steering combine to provide
robust power, precise placement control, and adaptable performance
across variable job-site terrains.
The machine integrates operator-focused features including proportional
joystick controls, a certified ROPS/FOPS cab, clear visibility lines,
adjustable seating, and an advanced instrumentation cluster. The
reinforced chassis, powerful drivetrain, and extensive attachment
compatibility make the JLG 943 a versatile lifting platform suited to
framing crews, masonry contractors, industrial logistics operations, and
rental fleets demanding high reliability under daily heavy loading
cycles.
The JLG 943 is powered by a Cummins QSF3.8L Tier 4
Final engine. This four-cylinder, turbocharged diesel engine is designed for
strong torque output, refined fuel efficiency, and full emissions compliance.
Engine specifications:
- Engine model: Cummins QSF3.8L Tier 4 Final
- Cylinders: 4
- Displacement: 232 cu in / 3.8 L
- Gross power: 110 hp / 83 kW
- Maximum torque: 348 lb-ft / 472 Nm at 1500 rpm
- Fuel tank capacity: 38.3 gal / 145 L
The engine’s torque characteristics support heavy lifting at height, confident
travel under load, and efficient hydraulic operation. Routine engine service
includes oil changes, DEF and emissions-system monitoring, air-filter
inspection, and cooling-system maintenance.
The telehandler uses a durable powershift transmission
optimized for performance in rough terrain and during heavy-duty load handling.
Transmission
- Type: Powershift
- Forward gears: 4
- Reverse gears: 3
- Top travel speed: 19 mph / 31 km/h
The transmission allows smooth shifting under load for controlled travel on
hills, grades, and uneven terrain.
Axles
- Trunnion-mounted planetary steer axles
- Integral steer cylinder
- High-bias limited-slip differential on front axle
These axle systems increase traction, stability, and maneuvering confidence,
distributing torque effectively even in low-traction environments.
Brakes
- Service brakes: inboard wet-disc brakes (front and rear)
- Parking brakes: wet-disc spring-applied, hydraulic-release
Wet-disc braking offers long service life, contamination resistance, and
consistent braking behavior under continuous duty cycles.
The electrical system includes safety, operational
monitoring, and diagnostic features essential for modern telehandler operation.
Instrumentation includes:
- Volt meter
- Hourmeter
- Engine oil pressure gauge
- Temperature gauge
- Fuel gauge
- DEF gauge
Optional electronic features include reversing cameras, multifunction displays,
ride control indicators, and anti-theft systems. The electrical harnessing uses
weather-sealed connectors for durability.
Chassis and Drive
System
- Full-time 4-wheel drive
- Heavy-duty welded-steel chassis with reinforced lift structure
- Optional enclosed cab and work-site protection packages
Tires:
- Standard: 370/75-28
- Optional: foam-filled or solid industrial tires
These tire options allow the operator to optimize traction, flotation, and
puncture resistance to match job-site conditions.
Steering modes:
- 4-wheel circle steering
- 4-wheel crab steering
- 2-wheel front steering
Hydraulic power steering ensures responsive control even while maneuvering with
elevated or extended loads.
Hydraulic
specifications:
- System capacity: 40 gal / 151.4 L
- Pump type: load-sense piston pump
- Auxiliary hydraulics for attachment functions
The load-sense hydraulic system adjusts pump output to demand, reducing fuel
consumption and improving smoothness of boom operation. Load-holding valves
prevent cylinder drift when supporting elevated loads.

- Fork sizes: 2.00 x 6 x 72 in (51 x 152 x 1800 mm)
- Operating weight: 24,912 lb / 11,300 kg
Periodic
maintenance:
- Replace hydraulic filters
- Inspect drivetrain and axle lubrication
- Check DEF and emissions systems
- Clean radiator and coolers
- Inspect structural welds and lift-arm components
- Replace fuel filters
- Diagnose electronic systems
