1258X

Engine

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

The 4-section boom features formed boom plates that offer greater 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 1258X has a capable 12,000-pound load capacity rating. It achieves forward reach up to 42 feet and a maximum lift height of 58 feet, 6 inches.

Outriggers

Axle-mounted outriggers come standard on the 1258X.

• Machine chassis will sway independent of the outrigger system.
• Outriggers positioned to provide clear visibility out to the fork tips.

Hydraulics

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.

Electrical

• 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.

Service

• 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.
