Chokweza chamkati cha boom ndi nsanja yogwirira ntchito yamlengalenga yofanana ndi boom yokhala ndi kapangidwe kapamwamba ka chassis kakang'ono, komwe kamathandiza kuti igwire ntchito bwino kwambiri pamene ikusunga thupi laling'ono, zomwe zimapangitsa kuti ikhale yoyenera kwambiri m'malo opangira mafakitale monga mafakitale ndi malo osungiramo katundu omwe amafunika kugwiritsidwa ntchito m'malo otsekedwa. Chokweza ichi chamagetsi chodziyendetsa chokha, chopanda chilengedwe, chili ndi kapangidwe katsopano ka boom komwe kamathandiza kuyenda ngakhale nsanjayo itakwezedwa, zomwe zimapangitsa kuti magwiridwe antchito azigwira ntchito bwino kwambiri.

Nsanjayi ili ndi makina oyendetsera magetsi amphamvu kwambiri omwe amapereka mphamvu zotulutsa mphamvu komanso kukwera, komanso malo ozungulira ochepa kwambiri—zomwe zimathandiza kuti ntchito ikhale yosinthasintha m'malo ovuta. Kapangidwe kake kopepuka kamapereka zabwino zingapo zazikulu: kuchepetsa mphamvu ya pansi kuti malo azitha kusinthasintha, kuchepetsa kugwiritsa ntchito mphamvu ndi mpweya woipa, komanso kunyamula mosavuta, komanso kuthekera kosuntha pakati pa malo pogwiritsa ntchito magalimoto ang'onoang'ono.

Dongosolo lamakono la batri limawonjezera moyo wa batri kwambiri, zomwe zimapangitsa kuti ntchito zambiri zitheke pa chaji imodzi. Pulatifomu yokhazikika ya anthu awiri imatha kukhala ndi ogwiritsa ntchito awiri pamodzi ndi zida zofunika. Chokweza cha boom chodziyendetsa chokha chili ndi dongosolo lowongolera lokwanira bwino lomwe limaphatikizidwa ndi boom yapamwamba yobwezeretseka, kuonetsetsa kuti ntchitoyo ikuyenda bwino, molondola komanso malo oyenera mkati mwa malo ogwirira ntchito. Zinthu izi zimapangitsa kuti ikhale yankho labwino komanso losangalatsa chilengedwe pantchito zamakono zamafakitale.
