Izinga Lokufakazela Ukuqhuma Kwe-Crane-Ubufakazi Bokuqhuma

Izidingo ezihlukene zezigaba ezivikela ukuqhuma zama-cranes zivela ezindaweni ezihlukahlukene ezivuthayo neziqhumane.. Lezi zidingo ziwela ezigabeni ezintathu eziyinhloko:

Isigaba Sesimo	Ukuhlukaniswa Kwegesi	Amagesi amele	I-Minimum Ignition Spark Energy
Ngaphansi Kwemayini	I	I-Methane	0.280mJ
Izimboni Ngaphandle Kwezimayini	IIA	I-Propane	0.180mJ
	IIB	I-Ethylene	0.060mJ
	I-IIC	I-hydrogen	0.019mJ

1. Okhreni abangaqhumi bekilasi I, eqokwe njenge-Exd I;

2. Okhrayini abangaqhumi bekilasi II, eqokwe njenge-Exd IIB T4 noma i-Exd IIC T4;

3. Okhreni abangaqhumi uthuli, eqokwe njenge-DIP A21 TA T4;

Ngaphakathi kweClass II, ama-cranes avikela ukuqhuma ahlukaniswe ngokuthi angashi “d” futhi iphephile ngaphakathi “i” zihlukaniswa zibe IIA, IIB, kanye namazinga e-IIC. Ama-Cranes anesilinganiso se-IIB afanele izindawo ze-IIA, kuyilapho ama-cranes alinganiswe nge-IIC afanele kokubili izindawo ze-IIA ne-IIB.
