ALLPROFORKS® 3AT47 Class 3 Top Carriage Bar

The ALLPROFORKS® 3AT47 Class 3 top carriage bar is a heavy-duty ITA upper carriage rail engineered for forklift systems requiring dependable fork engagement, accurate carriage alignment, and long-term structural durability. Designed for forklift carriage rebuilds, telehandler fork assemblies, pallet fork fabrication, agricultural attachments, and industrial material handling equipment, the 3AT47 provides the upper support structure necessary for stable high-capacity lifting performance.

Built to true ITA Class 3 specifications, this upper carriage rail is designed for systems maintaining the required 20-1/8-inch vertical spacing between the lower and upper carriage rails. Maintaining proper spacing is essential for stable fork positioning, accurate load distribution, and dependable forklift performance in demanding lifting environments.

Precision ITA Class 3 Forklift Geometry

Forklift carriage systems are classified according to standardized ITA dimensional specifications that determine proper fork compatibility and carriage performance.

Standard ITA Rail Spacing

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

The 3AT47 is engineered specifically for ITA Class 3 carriage systems and should be installed within a properly aligned carriage assembly maintaining correct geometry.

Accurate spacing helps ensure:

• Proper fork hook engagement
• Stable fork retention
• Even load distribution
• Reduced vertical fork movement
• Improved carriage alignment
• Reliable lifting stability

Improper rail spacing or mismatched carriage components can contribute to accelerated wear, unstable load handling, excessive fork movement, and unsafe operating conditions.

The upper carriage rail supports the top hook section of the fork blade and plays a major role in maintaining secure fork engagement during lifting operations. When paired with the correct lower carriage rail, the 3AT47 helps distribute lifting forces evenly across the carriage system while improving long-term durability.

Heavy-Duty Upper Rail Support

The reinforced design of the 3AT47 helps:

• Stabilize fork positioning
• Reduce excessive vertical fork play
• Improve carriage alignment under load
• Minimize hook and rail wear
• Improve load balance during operation
• Support safer material handling performance

This becomes especially important during:

• Heavy pallet handling
• Repetitive lifting cycles
• Off-center loading
• Warehouse operations
• Agricultural material transport
• Telehandler applications

Manufactured from high-strength structural steel, the 3AT47 is engineered for demanding industrial, agricultural, and commercial lifting environments.

Its reinforced construction is designed to withstand:

• Shock loading during pallet entry
• Continuous industrial use
• Rough operating conditions
• Heavy fabrication applications
• Commercial material handling
• Long-term structural stress

The compact 47-inch width makes this upper carriage rail ideal for narrower forklift carriage systems while still maintaining dependable fork support and lifting stability.

Designed for Forklift Fabrication & Material Handling Applications

The ALLPROFORKS® 3AT47 top carriage bar is commonly used in:

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

Its precision-manufactured dimensions help fabricators maintain proper ITA Class 3 compatibility while building or repairing heavy-duty forklift carriage systems.

For complete carriage fabrication, the 3AT47 should be paired with the appropriate 3AB47 Class 3 lower carriage rail to maintain proper fork engagement and dependable lifting performance.
