Return to Extendo

The Extendo 1246X is a true material handling workhorse, delivering impressive load capacity, superior longevity, and controllability on a wide array of applications.



Powered by a 117-horsepower Cummins QSF3.8 Tier 4 Final diesel engine with DEF and SCR aftertreatment. Side pod mounting offers easy service access while allowing excellent curbside visibility and ground clearance.

Drivetrain & Axles

Drivetrain and axles have been optimized to provide greater tractive effort with minimal tradeoff on top end speed.

  • Dana 223 Series high steer axles provide excellent tractive effort.
  • Tight steer angle capability provides efficient turning radius.
  • Dana VDT12000 Powershift transmission offers 3 speeds, forward and reverse.
  • Full time 4-wheel-drive with limited-slip front axle differential.

Boom Construction

Formed boom plates offer greater boom strength with less weight.

  • Boom deflection minimized for better control and accuracy placing loads.
  • Boom overlap nearly doubled to provide smoother operation and reduce contact forces on wear pads.
  • Fastener-less wear pads simplify service.
  • Bottom-mounted external extend cylinder significantly reduces load on wear pads; cylinder location also provides better service access to internal boom components.
  • Compression tilt design allows for a smaller bore cylinder with same tilt force.
  • Heavy-duty extension chains help ensure stable boom functions and longevity.

Capacity & Reach

The 1246X has a capable 12,000-pound load capacity rating. It achieves forward reach up to 30 feet and a maximum lift height of 46 feet, 6 inches.


The Extendo's hydraulic circuit delivers exceptional controllability, efficiency and cycle speeds.

  • Cylinder cushioning dampens the end of strokes – both extending and retracting – to prevent hard, jarring stops and avoid both wear-and-tear and potential load spills.
  • Single lift cylinder provides operator with clear sight lines.
  • Twin lines for tilt and auxiliary plumbing.

Steel Tanks

Damage-resistant, all-steel fuel and hydraulic tanks. Fuel tank provides ample fuel volume for a full day's work at 100% load.

Operator Station

The operator cab includes ergonomic seat, pedal, joystick and steering wheel positions. Available as an open canopy or enclosed cab, it features an all-steel interior with water-resistant components for easy washdown.

  • New analog/LCD gauge cluster.
  • Enhanced climate control system.
  • Split door design allows upper half to lock in the open position.
  • Flat, bolt-in glass can easily be removed or replaced.
  • Openable rear window improves air flow while keeping cab dry.
  • Lockable storage area under seat for manual, gloves and tools.


  • Split-system electrical panels allow for easier service of individual circuits.
  • Heavy-duty bright LED lighting.
  • Weather-sealed connections.
  • USB accessory plug in cab.
  • 12-volt accessory plug in engine bay.


  • Easy access to all filters and fluid level indicators.
  • Lockable fuel-fill in clean, accessible location.
  • Inside of boom easily accessible for service.
  • Non-tensioned boom hoses offer long service life.



The 1246X can be equipped with a variety of attachments, including pallet, lumber or block forks, truss boom, utility bucket, standard carriage, side tilt carriage (+/- 10°), or side-swing carriage (+/- 60°). Optional 10-foot tower with standard carriage provides 10 extra feet of lift height.
