Izikethi ezihambayo 、 Inqola yemithwalo ingasetshenziswa noma kuphi lapho izinto ezisindayo kufanele zihanjiswe khona.Umthwalo ungaphakanyiswa kusetshenziswa i-roller crowbar noma ujeke, okuvumela ama-skates ukuthi abekwe kalula.I-roller enayiloni enobubanzi obukhulu evalwe uphawu iqinisekisa ukuhamba kalula futhi isakaza umthwalo, ivikela ikhwalithi ephezulu emonakalweni obangelwa imithwalo yamaphuzu aphezulu kanye nokungcoliswa kwamafutha / amafutha.Ama-skates awalungiswa futhi afakwe izibambo ukuze kube lula ukuzithwala nokuzibeka.
Isebenza ezimpahleni ezihambayo nezijikelezayo.Lo mkhiqizo usebenzisa ikhwalithi ephezulu yokukhiqiza insimbi ye-carbon alloy steel
