MD3 Display

Parker IQAN-MD3 display provides instant engine and aftertreatment diagnostics.


Fully modulated Carraro Powershift transmission, with 4-speed forward and reverse with declutch, allows for safe deceleration before shifting gears.


Outboard planetary axles with oil-immersed, inboard service and parking brakes offer enhanced reliability.

Lift Cylinders

Two wide-stance, heavy-duty lift cylinders are slightly angled toward the center line of the chassis to triangulate the overall alignment. This keeps the boom centered as it elevates.

Rear Axle Stabilization

The rear axle stabilization system slows and locks the rear axle oscillation for enhanced stability as the boom is raised.

Sway Cylinder

Provides 24 degrees of fork leveling (12 degrees right and left of center).

Fork Leveling

The 1144B provides automatic fork leveling without needing slave cylinders.


Achieves forward reach up to 30 feet, 3 inches and a maximum lift height of 44 feet, 6 inches.


Pressure compensated hydraulic system and auxiliary boom tip hydraulics give operators the flexibility to use multiple hydraulic functions at once. Single joystick, pilot operated control covers all boom functions.

Quick Connect

Easily switch between standard fork carriage and a wide range of attachments.


4-wheel drive with 2-wheel, 4-wheel and crab hydraulic power steering modes provides agility in tight spaces.
