Crankshaft thiab scissor nqa: tsim nta

Huab cua yog siv rau tus me nyuam ntawm hnyav loads ntawm tej qhov siab. Qhov no cov khoom tswj tib neeg ua hauj lwm thiab qhia los ntawm hom mus rau hauv:

• crankshaft;
• scissor;
• telescopic;
• masted.

Wb tham ntau txog cov thawj ob hom, xws li. A. Nws yog tsis suav hais tias yog feem ntau nrov thiab ntau.

Scissor. Nws yog hu ua li ntawd vim hais ntawm nws cov lifting system muaj levers thiab hydraulic lub tog raj kheej yog heev uas zoo sib xws nyob rau hauv nws tsim rau txiab. Lub system ntawm thooj voos kheej kheej thiab levers - ib tug them nyiaj yug rau lub platform uas tus luj yog yuav tsum tau tsa. Rau ib tug xov tooj ntawm cov kev tshawb fawb uas muaj tsuas ntsug zog, koj yuav tsum yuav scissor nqa rau kab rov tav - cranked.

Scissor nqa muaj ib tug me me luaj li cas, vim li ntawd nws yog ib qho yooj yim mus rau tiv nrog lub chaw ua hauj lwm nyob rau hauv ib qho nyuaj mus cuag qhov chaw. Nthuav fact: txiav txim scissor nqa ntsiab cai no siv nyob rau hauv lub laptop keyboard.

Qhov no mobile ntaus ntawv yog kev koom siv nyob rau hauv me me siv qhov chaw, nyob rau hauv warehouses nyob rau hauv lwm qhov chaw uas nws yog tsim nyog los tsa ib tug hnyav load rau ib tug zoo siab. Tsiv cov khoom nrog rau cov kev pab los ntawm lub chassis, los ntawm kev uas nqa tsub kom maneuverability. Mus ua hauj lwm nyob rau hauv cov khoom no yuav tsum muaj ib tug tshaj plaws ntawm 2 cov neeg. Yog hais tias ib tug txawv teb chaws yam khoom twg thiaj li raug nyob rau hauv lub platform, nqa tam sim ntawd lawm ua hauj lwm, tab sis tsis tawg. Nruab kom tsis txhob tus siab kawg nqa qhov siab, uas yog tseem ceeb rau lub du lag luam ntawm lub hydraulics.

Muaj yog ib tug lub cev muaj zog tiv thaiv thiab tau mos mos nres, ceev tswj ntawm lub hydraulic system. Scissor nqa yog cheaper crankshaft vim muaj ib tug yooj yim mechanism. Ib co ua qauv muaj peev xwm ntawm lifting mus txog rau 10 tons ntawm cov khoom rau ib qhov siab ntawm nees nkaum-tsib meters. Scope ntawm no hom ntawm cov khoom - qhov chaw uas lwm txoj kev ntsug zog ntawm tus cargo yog unreal. Siv tsa ob khoom thiab cov neeg ua tsev kawm ntawv los yog warehouse. Lug siv nyob rau hauv kev tsim kho chaw, nyob rau hauv lub engineering kev lag luam, kev txij nkawm thiab kho ntawm cov txuas hniav thiab cranes rau lub installation ntawm advertising sawv, nyob rau hauv lub chaw ua hauj lwm nyob rau hauv cov sab nrauv ntawm cov tsev.

Crankshaft. Qhov no lub npe tau muab vim lub fact tias cov crank hoist tsim yog ua raws li yog hais rau ib tug ntev heev ceg ib tug ob peb laps, uas yuav tsum tau bent nyob rau hauv txawv kev qhia. Muaj cov qauv nrog ib tug diesel thiab electric tsav. Nrog diesel - ntau haib. Cranked nqa scissor loj npaum li cas thiab no heev txwv lub Scope ntawm nws siv. Feem ntau cov feem ntau nws yog siv nyob rau hauv ib tug qhib qhov chaw, t. Yuav kom. Nws yog nqa tau lub load rau ib qhov siab ntawm plaub caug meters. Tab sis ib tug ntau ntawm qhov ceeb thawj, nws yuav tsis siv. Yog hais tias koj xav tau kev los txhawb thiab tsiv mus nyob rau load nyob rau hauv cov kev taw qhia, tsis yog thiab nce thiab nqis, yuav ib tug crank nqa - lub feem ntau txawj ntse tshuaj. Nws raug nqi kim kim txiab, tab sis cov ntau yam ntawm kev ua ub no thiab nws yog loj npaum li cas thiab ntau.

Qhov no lifting khoom muaj ib tug muaj kev kawm siab vim hais tias ntawm lub proportional tswj ntawm movements thiab tsis tau heev ob peb boom tswj manipulation. Tag nrho cov-vajvoog kev pab txhawb nqa ntaus ntawv yuav qhia lub sij hawm mus nqa tawm kev ua hauj lwm nyob rau hauv lifting loads nyob rau hauv ceev Metakhim. Mob siab siv no hom ntawm nqa nyob rau hauv cov kev siv thiab los ua ke ua hauj lwm, uas yog. Yuav kom. Ua rau nws tau tsa ib tug load nyob rau hauv ib tug me me qhov chaw. Vim lub curving sub nrog loj lawm nyob rau hauv ntev, cov txheej txheem no ua hauj lwm zoo txawm nyob rau hauv siab altitudes, nyob rau hauv tsis yooj yim tej yam kev mob, qhov chaw uas qhov kev siv ntawm lwm yam khoom tsis yooj yim sua.
