Hlau tensioners yog categorized rau hauv tes ua haujlwm (qib) hoists, ratchet hlau tensioners, thiab ob-nuv hlau tensioners.
Tes-ua haujlwm (qib) hoists feem ntau yog siv rau tensioning fais fab kab thiab overhead cables, ntxiv rau rub thiab txav cov khoom hnyav xws li cov khoom siv. Lawv kuj tau siv los ua kom ruaj ntseg cov cuab yeej loj thiab cov khoom lag luam thaum lub sijhawm thauj khoom thauj. Tes-ua haujlwm (qib) hoists raug cais los ntawm lawv cov txheej txheem tsav: phau ntawv thiab qib-ua haujlwm. Phau ntawv hoists ua tiav tensioning thiab nqa los ntawm rub cov saw, thaum lub zog hoists muaj xws li saw lever hoists thiab hlau hlua lever hoists. Lever hoists ua tiav tensioning thiab lifting los ntawm kev khiav hauj lwm ib tug lever ntawm cov saw los yog hlau hlua. Tes ua haujlwm (siv) hoists tuaj yeem siv rau kev nqa, rub, txo qis, thiab ua haujlwm calibration. Nrog rau qhov sib ntxiv ntawm cov khoom siv tshwj xeeb xws li hlau clamps, kev ua haujlwm tsis yog linear traction tuaj yeem ua tau, thiab cov haujlwm tsim nyog tuaj yeem xaiv tau yooj yim. Lub peev xwm thauj khoom tuaj yeem muab faib los ntawm cov cuab yeej me me tonnage. Rau qhov hnyav dua tonnage loads, ob peb tes ua haujlwm (lever) hoists tuaj yeem siv ua ke.
Lub ratchet hlau tensioner, tseem hu ua ratchet tes-ua haujlwm hoist, yog ib qho cuab yeej siv hauv kev siv hluav taws xob xaim hluav taws xob kom nruj steel strands thiab me-section conductors. Feem ntau, ib lub xov hlau clamp yog siv los tiv thaiv tus neeg xyuas pib ua ntej, thiab tom qab ntawd cov tensioner yog siv los zawm tus neeg xyuas pib mus rau qhov tsim nyog sag.
Ob chav nuv hlau tensioner yog ib qho cuab yeej siv thaum lub sij hawm siv hluav taws xob xa hluav taws xob rau kev ua kom nruj txiv neej cov xov hlau, kho qhov chaw ntawm cov khoom siv lossis cov khoom siv, hloov cov insulators, thiab lwm yam haujlwm tensioning. Ob chav nuv hlau tensioners muaj nyob rau hauv steel thiab aluminium alloy. Lub qub yog hnyav dua tab sis muaj peev xwm ua tau siab dua, txog li 100kN; tom kawg yog sib dua thiab yooj yim rau nqa thiab siv, tab sis nws qhov siab tshaj plaws load feem ntau tsis ntau tshaj 50kN.
Txhawm rau siv cov hlau tensioner, ua ntej loosen cov hlau xaim hlua los yog galvanized hlau hlau ntawm lub tensioner thiab ruaj ntseg rau crossarm. Clamp tus neeg xyuas pib nrog hlau clamps, thiab tom qab ntawd ua haujlwm tshwj xeeb wrench. Hlau tensioners tuaj yeem txhim kho kev nyab xeeb thaum nqa thiab thauj khoom.
