ALLPROFORKS® 3AB47 Class 3 Lower Fork Carriage Bar

The ALLPROFORKS® 3AB47 Class 3 lower fork carriage bar is a heavy-duty ITA lower carriage rail engineered for forklift systems requiring dependable fork support, accurate carriage alignment, and long-term structural durability. Designed for forklift carriage rebuilds, telehandler frames, pallet fork fabrication, agricultural loader attachments, and industrial material handling equipment, the 3AB47 provides stable lower fork support for demanding Class 3 lifting applications.

Built to true ITA Class 3 specifications, this lower carriage rail is designed for systems maintaining the required 20-1/8-inch vertical spacing between the upper and lower carriage rails. Maintaining proper carriage geometry is critical for stable fork engagement, proper load distribution, and dependable lifting performance in high-capacity material handling environments.

Precision ITA Class 3 Carriage Geometry

Forklift carriage systems are classified according to standardized ITA spacing dimensions that determine fork compatibility and lifting stability.

Standard ITA Carriage Spacing

• Class 2 carriage spacing: 16 inches
• Class 3 carriage spacing: 20-1/8 inches

The 3AB47 is engineered specifically for Class 3 forklift carriage assemblies and should be installed within a properly aligned carriage system maintaining correct ITA geometry.

Accurate spacing helps ensure:

• Proper fork heel engagement
• Stable vertical fork alignment
• Consistent load distribution
• Reduced hook and rail wear
• Dependable fork retention
• Improved lifting control

Incorrect spacing or mismatched carriage components can contribute to unstable fork movement, accelerated wear, improper load handling, and reduced lifting stability.

The compact 47-inch width is ideal for narrower forklift carriage systems while still maintaining dependable support for industrial lifting applications, warehouse pallet handling, and telehandler fork assemblies.

Heavy-Duty Lower Rail Support

The lower carriage rail supports the heel section of the fork blade during lifting operations. When paired with the appropriate upper carriage rail, the 3AB47 helps maintain stable fork positioning while distributing lifting forces evenly across the carriage system.

This reinforced support helps:

• Reduce excessive fork movement
• Improve carriage alignment under load
• Stabilize fork positioning
• Improve lifting precision
• Reduce stress on fork hooks and rail components
• Support safer material handling performance

Manufactured from high-strength structural steel, the 3AB47 is engineered to withstand:

• Repetitive heavy lifting cycles
• Off-center loading stress
• Fork impact during pallet handling
• Continuous warehouse operation
• Rough terrain material handling
• Heavy fabrication and rebuild applications

Its reinforced profile helps maintain dimensional stability and dependable structural performance under sustained workloads.

This lower carriage rail is commonly used in:

• Forklift carriage rebuilds
• Telehandler fork systems
• Custom pallet fork fabrication
• Loader attachment manufacturing
• Agricultural lifting equipment
• Warehouse material handling systems
• Industrial lifting assemblies
• OEM carriage construction
