<p>PROBLEM TO BE SOLVED: To provide the ground height slide rule with which the ground height of a container and the ground height of a truck can easily and precisely be found irrelevantly to the kind of the container. SOLUTION: One of upper and lower fixed rules 10 and 11 is provided with a container floor thickness scale 16 and a load height scale 17 in upper and lower stages, and the scales are so set that the value obtained by adding both the scales 16 and 17 is the constant value obtained by subtracting the chassis height H1 of a trailer 21 from container restriction height H3; and a sliding rule 13 is provided with an excessive height scale 19 showing excessive height O/H exceeding the container restriction height H3 and a container ground height scale 20 in upper and lower stages, and at each matching position, the value obtained by subtracting the excessive height scale 19 from the container ground height scale 20 is set to the container restriction height H3.</p> |
