Uhlu olusisiseko lweikreni yokulinganiselainokwahlulwahlulwa ibe ziindidi ezintathu, eyokuqala yi-mechanical balancing crane, oluluhlobo oluqhelekileyo lwe-balancing crane, oko kukuthi, ukusebenzisa i-motor ukuqhuba isikrufu ukuze inyuke ukuze iphakamise impahla; eyesibini yi-pneumatic balancing crane, esebenzisa umthombo womoya ukufunxa impahla, ukuze ikwazi ukuphakamisa. Uhlobo lwesithathu yi-hydraulic counterbalance crane, esetyenziswa ngokubanzi ekuphakamiseni impahla enzima.
Ikhawuntarai-crane yokulinganisela"ngokulinganisela kwayo kobunzima bomxhuzulane" kwenza intshukumo ihambe kakuhle, ilula kwaye ilula, kwaye ifanelekile ngokukodwa emva kwenkqubo yokuphathwa rhoqo kunye nokuhlanganiswa, okunokunciphisa kakhulu amandla omsebenzi kwaye kuphucule ukusebenza kakuhle komsebenzi.
Isetyenziswa kakhulu kwizityalo zoomatshini, ezothutho, iikhemikhali, kunye nezinye iindawo zoshishino lokukhanya, kwaye isebenza kakuhle kakhulu ekulayisheni nasekukhupheni izixhobo zoomatshini, imigca yokuhlanganisa, imigca yokucubungula, ukulayisha nokukhutshelwa kweemveliso ezigqityiweyo, iibhokisi zesanti, kunye nezinto zokugcina impahla.
Iingenelo ezintathu eziphambili ze-balance crane.
1. Ukusebenza kakuhle kokungaguquguquki. Inxalenye yengalo yekreni echaseneyo yenzelwe ngokwemigaqo yokulinganisela kunye nokudibana, kwaye kwangaxeshanye, ubunzima bento ekwihoko (ubunzima bokuphakamisa) abuyitshabalalisi le meko yokulinganisela. Kufuneka koyiswe kuphela ukuxhathisa okuncinci kokungqubana okuqengqelekayo xa kushukuma.
2. Ukusebenza kakuhle. Ngenxa yengalo yayo eqinileyo, into ephakanyisiweyo ayizukushukuma lula njengekhreyini okanye i-electric hoist xa ishukuma.
3. Kulula ukuyisebenzisa. Umsebenzisi kufuneka abambe into ngesandla aze acinezele iqhosha lombane okanye ajike isiphatho ukuze into ihambe kwindawo enemilinganiselo emithathu ngokwendlela ebekwe ngayo kunye nesantya esifunekayo ngumsebenzisi (i-variable speed counterbalance crane). I-crane yokulinganisela uhlobo olungenamxhuzulane inamandla okulawula isantya sezinto ezihambayo ngokwentando yomqhubi kunye nemvakalelo yesandla.
