- 1) Positioning Between the Aluminum Frames
Position the frames using the V groove (marked with (A) in the above diagram) as a guide and secure them with bolts (4) (listed in Table 18) on the base. - 2) Connecting the Aluminum Frames
After positioning is complete, the frames can be secured in position using the frame joints.*
※The frame joint is not intended for positioning between aluminum frames. - 3) Installing the Pallet Guide Rail
Make a hole of an appropriate size at the V groove position marked (B) in the above diagram and secure the rail using the hexagonal bolt (1) listed in Table 18. - 4) On models marked with * in Table 18, there is a difference of 60 mm in height between the aluminum frame and pallet guide rail.
To offset the height difference, fit a collar for height adjustment under the pallet guide rail.
4. Conveyor Leg Pitch
Determine the conveyor leg pitch based on the mass of the conveyed objects and the second moment of area given in Table 19. However, ensure the conveyor layout is designed so that the frameconnecting section is supported by the legs, regardless of the second moment of area.
Calculation of Leg Pitch (ℓ)
- I = Second moment of area (cm4)(See Table 19 )
- W = Lifting weight (kg/m)
- δ = Deflection (2mm)
- E = 7.0 × 103 (kg/mm2)
Note) The total conveyed mass (W) is not always distributed evenly between the two conveyor strands. This is taken into account with the factor (0.6).
| Classification | Frame No. | Second moment of area (I) cm4 |
|---|---|---|
| Aluminum frame | RF2030VRP-R2 | 17.127 |
| RF2040VRP-R2 | 40.185 | |
| RF2050VRP-R2 | 84.039 | |

| RF2060VRP-R2S | 171.761 | |
| RF2080VRP-R2S | 360.726 |
※The second moment of area (I) of the frame for the drive and driven sections is the same as given in the table above.

- ・A notch is provided on the right-end bottom in the diagram above (Example of RF2030VRP-R1K)
4)Notes on Handling Aluminum Frame with Steel Rail
- 1. When cutting the aluminum frame with steel rail for use
- (1)Do not cut the screw section on the frame.
- (2)Remove burrs and chips from the cut surface.
- (3)Connect and secure the steel rail with the inner rail, and the inner rail with the frame of the base frame by screws 15 to 30 mm away from the cut area.
- (4)Machine all parts individually. Completely remove burrs and chips produced by machining before starting reassembly. Be sure there is no misalignment at the 45° cut section either.
- 2. Connecting the Frame
If there is a difference in level on the abutting surface of the steel rail after connecting the frame (in vertical and horizontal directions), chamfer the corners slightly to avoid chain rollers getting caught.
