Ngawaphi amanyathelo okhuseleko okugcinwa kunye nokuthuthwa kwemibhobho edityanisiweyo ye-spiral-diameter enkulu? Umhleli olandelayo uza kukwazisa.

1. Ukupakishwa kombhobho kufuneka kukwazi ukuphepha ukukhulula kunye nomonakalo ngexesha lokulayishwa okuqhelekileyo, ukukhupha, ukuthutha kunye nokugcinwa.
2. Ukuba umthengi uneemfuno ezikhethekileyo zezinto zokupakisha kunye nendlela yokupakisha yombhobho wensimbi ye-spiral, kufuneka iboniswe kwisivumelwano; ukuba ayiboniswanga, izinto zokupakisha kunye nendlela yokupakisha iya kukhethwa ngumthengisi.

3. Izinto zokupakisha kufuneka zihlangabezane nemimiselo efanelekileyo. Ukuba akukho mpahla yokupakisha ifunwayo, kufuneka ihlangabezane nenjongo yokusetyenziswa kwaye iphephe inkunkuma kunye nokungcoliseka kwendalo.

4. Ukuba umthengi ufuna ukuba umbhobho we-spiral-diameter enkulu akufanele ube nomonakalo njengama-bumps phezu komhlaba, unokuqwalaselwa ukusebenzisa isixhobo sokukhusela phakathi kwemibhobho. Isixhobo sokukhusela sinokusebenzisa irabha, intambo ye-hemp, ilaphu lefiber, iplastiki, i-cap cap kunye nokunye.
5. Iimveliso ezinodonga oluncinci zingasebenzisa inkxaso ye-tube okanye i-tube yangaphandle yokukhusela imilinganiselo yokukhusela isakhelo. Izinto ze-bracket kunye nesakhelo sangaphandle sikhethwe kwizinto ezifanayo zetsimbi kunye nempahla yombhobho.

6. Kuxelwe ngokubanzi ukuba imibhobho ye-spiral enobubanzi obukhulu kufuneka ipakishwe ngobuninzi. Ukuba umthengi ufuna ukudibanisa, kunokuqwalaselwa njengento efanelekileyo, kodwa i-caliber kufuneka ibe phakathi kwe-159MM kunye ne-500MM. Izinto ezidibeneyo kufuneka zipakishwe kwaye zinyanzeliswe ngamabhande ensimbi, kwaye i-strand nganye kufuneka iguqulwe ibe yincinci ibe yimicu emibini, kwaye kufuneka inyuswe ngokufanelekileyo ngokuhambelana nobubanzi obungaphandle kunye nobunzima bombhobho ukuze ugweme ukukhulula.

7. Iimveliso ezinobude obumiselweyo azinakudityaniswa.
8. Ukuba kukho i-threaded buckles kwiziphelo zombini zombhobho, kufuneka ikhuselwe ngumkhuseli wentambo. Gcoba ioyile yokuthambisa okanye iarhente yokuchasa umhlwa kumsonto. Iziphelo ezimbini zombhobho zivulwa, kwaye abakhuseli be-nozzle banokongezwa kuzo zombini iziphelo ngokweemfuno.
9. Ukuba umbhobho ojikelezayo onobubanzi obukhulu ufakwa kwisikhongozeli, isikhongozeli eso kufuneka sigqunywe ngezixhobo ezithambileyo zokumelana nokufuma njengelaphu lelaphu elilukiweyo kunye nemethi yeendiza. Ukuze uthintele umbhobho ukuba usasazeke kwisitya, unokubotshwa okanye udityaniswe kunye ne-bracket yokukhusela ngaphandle kwayo.
