Ama-trailer angu-Semi-asetshenziswa kakhulu ekuthuthweni kwempahla, ekusabalaliseni izinto, ekwakhiweni kobunjiniyela nezinye izinkambu ngenxa yomthamo wawo oqinile wokuthwala nokuzinza okuhle. Ikakhulukazi{2}}ezokuthutha ezihamba ibanga elide kanye nezokuthutha zomgwaqo onguthelawayeka, ama-semi{3}}ama-trailer azuze ukuqashelwa okubanzi nokunconywa ngokusebenza kahle kwawo okuphezulu nokuphepha.
2. Izinzuzo ezibalulekile
(1) Umthamo oqinile wokuthwala: Ama-semi{1}}ama-trailer enziwe{2}}ngensimbi yekhwalithi ephezulu, anesakhiwo esiqinile futhi akwazi ukumelana nesisindo esikhulu sempahla. Lokhu kwenza ama-semi{4}}ama-trailer abe nokusebenza kahle okuphezulu kwezokuthutha kwezokuthutha futhi kunciphisa izindleko zokuhamba.
(2) Ukuzinza okuhle: Idizayini yama-semi{1}}ama-trailer icabangela ngokugcwele izinkinga zokuzinza phakathi nokushayela. Ngokusebenzisa izilungiselelo ezinengqondo ze-counterweight kanye nesistimu yokumiswa, ama-semi{3}}ama-trailer angagcina ukuzinza okuhle ngesivinini esiphezulu nezimo zomgwaqo eziyinkimbinkimbi, aqinisekise ukuphepha kokuthuthwa kwempahla.
