3AT47 47-Inch Class 3 Top Carriage Bar

The ALLPROFORKS® 3AT47 47-inch Class 3 top carriage bar is an upper rail for building or repairing compact forklift carriages, pallet-fork frames, and material-handling attachments. Its narrower 47-inch width suits designs that do not need the broader fork-positioning range of a 72-inch rail. Manufactured from high-strength structural steel, the 3AT47 gives compatible ITA Class 3 hook-type forks the upper engagement surface required in a properly designed carriage.

This product is one weld-in fabrication component, not a complete carriage or a universal bolt-on replacement. It may be used in forklift carriage rebuilds, telehandler fork frames, loader pallet-fork assemblies, agricultural attachments, warehouse equipment, and custom industrial builds when the finished structure is engineered for that use. Before ordering, verify the required bar length, carriage class, fork-hook dimensions, frame design, welding procedure, and machine specifications.

Upper-Hook Engagement in a Compact Carriage

Hook-type forks attach to a carriage at two points. Each fork’s upper hook hangs on the top rail, while its lower hook engages the lower rail. These opposing connections keep the forks seated against the carriage while allowing them to be positioned for the load. The 3AT47 provides the upper connection; it does not form a complete fork-retention system or determine the capacity of the finished assembly by itself.

The notches visible along the upper edge provide locking positions for compatible fork-positioning hardware. When the forks, locks, and rails are correctly matched, an operator can move the forks across the carriage and secure them at the needed spacing. The 47-inch width makes this bar a practical choice for compact frames used with standard pallets, farm supplies, packaged materials, and other loads that do not require an extra-wide carriage.

A narrower or wider rail does not raise the forklift’s rated lifting capacity. Safe capacity depends on the entire system, including the machine data plate, load center, fork rating, attachment weight, frame strength, welds, and any required derating. Operators must follow the equipment manufacturer’s instructions and the rating of the lowest-capacity component.

Class 3 Fit, Fabrication, and Matching Lower Bar

PRO-Link specifies a 20-1/8-inch vertical rail setup for the 3AT47. Fabrication drawings may identify their measurement points differently, so confirm exactly where that dimension is taken before welding. The upper and lower rails must be straight, parallel, level, and located to match the intended Class 3 forks. Neither the 47-inch length nor the Class 3 designation alone confirms fit with a particular forklift, telehandler, loader, or custom frame.

Pair the 3AT47 with the ALLPROFORKS® 3AB47 Class 3 lower fork carriage bar when the build requires matching 47-inch rails. The lower bar, forks, frame members, mounting plates, and fabrication work are separate unless the product listing expressly states otherwise.

Installation and final inspection should be completed by qualified professionals familiar with welded lift-truck carriages and material-handling structures. They should verify joint design, alignment, fork-hook engagement, locking operation, clearances, and completed-frame capacity before the equipment enters service. Routine inspections should check the rails, welds, fork hooks, and locking parts for wear, cracking, looseness, damage, or distortion.

The 3AT47 is covered by PRO-Link’s one-year limited warranty against manufacturer’s defects. Review the complete warranty terms for coverage details.

Questions & Answers

Is the 3AT47 the upper or lower Class 3 carriage bar?

The 3AT47 is the 47-inch upper bar. Its matching lower component is the ALLPROFORKS® 3AB47 lower fork carriage bar.

Does the 3AT47 include a complete forklift carriage?

No. It is one upper rail. The lower bar, forks, frame structure, mounting components, welding, and other required parts are sold or selected separately unless the listing says otherwise.

Will this 47-inch Class 3 top carriage bar fit any Class 3 forklift?

No. Compatibility depends on the fork-hook geometry, finished rail position, carriage width, frame structure, mounting method, welding requirements, and machine specifications. Confirm the complete design before ordering or fabrication.
