1. Intebe yubushakashatsi irangwa nimirongo 2 yumukara, intera iri hagati ya 250 ± 0.2mm;
Umurongo wo hasi, 3 ± 0.2mm uhereye kumpera yintebe yubushakashatsi, ni umwanya wikintu cyo kwinjiza kumpera;
Umurongo muremure niwo murongo wo hagati wumuyoboro wamazi hafi 25mm hepfo uhereye hejuru yikigereranyo.
2. Impengamiro ya platform yubushakashatsi ni dogere 25;
3. Ibikoresho: cyangwa igikoresho gisa nacyo (gikoreshwa muguhindura umwanya wo hagati wikigereranyo) gishobora gukosora ingero kumwanya wa (140 s 0.2) mm ihuza umurongo werekeza.
4. Ahantu rwagati (kugirango harebwe imiyoboro ya axial irekura amazi);
