Carton Clamping Telescopic Fork
Side Clamping and Pulling for Light-Load Storage
The RFKJ-0050 is a three-stage double-extension clamping fork with a rated load capacity of 50 kg. It is mainly designed for totes, cartons, rolled materials, and other light loads that need to be picked from the side or end rather than supported by a conventional pallet fork.
The standard application data covers tote sizes such as 600 × 400 × ≥100 mm. Dimensions can also be customized according to project requirements.
Instead of entering underneath a pallet, the Carton Clamping Telescopic Fork uses a lateral hooking and pulling method. This allows the spacing between adjacent totes to be reduced, making the structure suitable for dense storage positions and double-deep rack layouts.

Reduced Tote Spacing and Simplified Rack Support
The side-pull handling method can reduce the clearance required between storage units. This allows the warehouse layout to make more effective use of available rack space.
The product information also states that the system can eliminate the need for certain rack accessories such as corbels and supporting strips. Totes can instead be supported directly by shelf panels or cross-beam shelving, depending on the storage design.
This difference is important when comparing tote handling structures. The procurement value is not limited to the fork itself. The selected handling method can also affect rack spacing, shelf structure, and the mechanical interface between storage locations and the automated handling device.
For projects involving double-deep positions or closely arranged totes, these factors should be evaluated together during the warehouse design stage.

900 mm Stroke with Controlled Positioning
The RFKJ-0050 has a maximum load capacity of 50 kg. The maximum stroke is 900 mm, with an additional 50 mm safety distance. Both the outer fork and inner fork are 690 mm long.
Maximum unloaded speed is 1 m/s, while maximum loaded speed is 0.5 m/s. Positioning accuracy reaches ±2 mm and precise positioning time is 2.5 seconds.
However, load weight alone is not enough to determine whether a product is suitable for clamping. The packaging strength, clamping position, external dimensions, and the way the load reacts to clamping force should all be checked during selection.
The spacing of the pulling fingers and related structural dimensions can also be determined according to the actual tote or product configuration.
Custom Engineering for Non-Standard Loads
in one-stop service
Anhui Rayo Automation Technology Co., Ltd. has technical teams covering mechanical design, electrical control, software development, and system integration. This enables the company to develop handling solutions for non-standard materials, totes, and automated storage stations.
The company has approximately 500 employees and operates research and development centers and branches in Shenyang, Shanghai, and Guangzhou. Manufacturing equipment includes CNC machining centers, gantry machining centers, laser cutting machines, CNC lathes, 3D printers, and bending machines.
For a Carton Clamping Telescopic Fork project, the material type, tote dimensions, required stroke, and installation interface can be confirmed at the beginning of the project. Mechanical, electrical, and commissioning teams can then coordinate the design and onsite implementation according to those confirmed conditions.
