We developed 4 type of small dinting machines, which has some feauture to get high efficiency and reduction of labor Then, we put to use them at some pit in fact and investigated about following points
(1) Ability of dinting
(2) Suitability of machines
(3) Durability of machines
(4) Application to subsidiary work
In findings, every machine made higher efficiency by a large marginlv than human efforts. And they can raise it morenver by improvement of way.
About suitability of machines, they have no difficulty on space where we planned.
Also they can answer to operations to make the most of each feauture.
About durability of machines, each was dammeged partly, but there were no defect in structural. We can find COMP of subsidiary work with them.
We expect that they could raise the overall effeciency on maintenance of roadway.
