[ Example of Seiko Rack SRC type body and spring model selection ]
Please see the table.
Please check the three points of the tilt material / structure of the truck, the tilt height, and the tilt length.
Select the item that meets the conditions from the left column (1) to (7) from the tilt material / structure and tilt height.
Select the spring that intersects with the "model (combination)" in the table from the tilt length.

Example : 4t standard body (without crane), installation conditions: normal hinge, tilting step amount 0mm, floor frame height 100mm
○ Tilt material / structure: Aluminum tilt ○ Tilt height: 800mm
○ Tilt length: L = 6.2M

will do. From the installation conditions, the main body is SRC (48781).
Select item (5) from the tilt material / structure and tilt height. Since the tilt length is about 6.4 to 8.5M, the spring selection is SRC550.
(If the tilt length is the boundary, it is safer to select a strong spring.)

* If a steel lashing rail is installed, the unit weight per 1M will increase by 3kg. In the case of the above example, select item (6) from the unit weight. From the tilt length, I think that SRC550 + auxiliary spring is good for spring selection.
