Iko kukurumidza kuchinja kwemabooms kuburikidza neK100 system kuchaita kuti makondirakiti afunge zvakare nzira dzavanoshandisa pamabasa ekuputsa. Semuenzaniso, mabhomu anosvika kure anogona kushandiswa pamativi akareba echivako; apo simba guru rekuparadza rinodiwa, kukurumidza kuchinja kune pfupi boom kunogona kuitwa kuunza zvinorema, zvine simba zvekuparadza maturusi. Mukuwedzera, iyo yekuchera imwe chete inogona kutakurwa nezvinhu zvekutakura, kuchengetedza pamari yekushandisa panzvimbo.

PC490HRD-11 Iyo pasi yese yemuchina inochengetedzwa kudzivirira kukuvara kubva kumarara pasi. Pamusoro peiyo yakakwira yekuwedzera boom mamiriro, iyo PC490HRD-11 yepasi chimiro inosimbiswa zvakare kuitira kuti ikwanise kurarama nehuremu huremu uye hurefu hwekuwedzera masimba kumberi kwe telescopic boom.
