Ibisobanuro ku bicuruzwa:

Umunara wa crane Nylon Pulley nkubwoko bumwe bwibikoresho bya pulasitiki bidasubirwaho byakoreshejwe cyane muburyo bwa crane.Nylon pulleys yabanje kwakirwa muminara ya crane yatangiriye mubudage kugirango isimbuze ibyuma kubera uburemere bworoshye, kurinda insinga zicyuma, Kwiyitirira amavuta, kwishyiriraho byoroshye, kugiciro gito.Buhoro buhoro nylon pulleys ikoreshwa cyane muminara ya crane yo guterura kwisi yose ikora amateka yimyaka irenga 20.

Gusaba: umunara wa crane;

Ubushobozi bwo gutanga:

1, Umusaruro wa buri kwezi Ibice birenga 100000

2, Abakozi barenga 150 bahagaze

3, 23 abakozi ba tekinike gushushanya no kubara

4, Igisubizo cyihuse kubicuruzwa byabigenewe

5, Ubwoko burenga 1000 bwa nylon pulleys mububiko

6, Gutanga vuba
