1. பொதுவாக, காச்டர்களால் ஏற்றப்படும் எடையை முதலில் கருத்தில் கொண்டு, சூப்பர் மார்க்கெட்டுகள், பள்ளிகள், மருத்துவமனைகள், அலுவலக கட்டிடங்கள், ஹோட்டல்கள் மற்றும் பிற இடங்களில் பயன்படுத்துவதற்கான பொருத்தமான சக்கரக் கட்டமைப்பை தேர்வு செய்ய வேண்டும், ஏனெனில் தரை நல்லது, மிதமானது மற்றும் கையாள வேண்டிய பொருட்கள் எளிதானவை, (ஒவ்வொரு காச்டரும் 10-140kg வரை ஏற்றுக்கொள்கிறது), இது 2-4 மிமீ தடிமனுள்ள மென்மையான எஃகு தாளால் அச்சிடப்பட்ட மற்றும் உருவாக்கப்பட்ட மின்கலக்கருவி சக்கரக் கட்டமைப்பை தேர்வு செய்வதற்கு பொருத்தமாகும். சக்கரக் கட்டமைப்பு எளிதானது, செயல்பாட்டில் நெகிழ்வானது, அமைதியானது மற்றும் அழகானது. இந்த மின்கலக்கருவி சக்கரக் கட்டமைப்பு பந்து ஏற்பாட்டின் அடிப்படையில் இரட்டை வரிசை பந்துகள் மற்றும் ஒற்றை வரிசை பந்துகள் என வகைப்படுத்தப்படுகிறது. அடிக்கடி நகர்த்துதல் அல்லது கையாள்வதற்காக இரட்டை வரிசை பந்துகள் பயன்படுத்தப்பட வேண்டும்.
2. தொழிலகங்கள் மற்றும் கையிருப்புகளில், பொருட்கள் அடிக்கடி கையாளப்படுவதும், சுமை கனமாக இருப்பதும் (ஒவ்வொரு காஸ்டருக்கும் 280-420kg) காரணமாக, தடிமனான எஃகு தகடு (5-6 மிமீ) அச்சுப்பதிவு, சூடான உலோகத்தை உருவாக்குதல் மற்றும் இரட்டை வரிசை பந்து சக்கரங்களின் கைத்தொகுப்பை பயன்படுத்துவது பொருத்தமாகும்.
3. இது துணி தொழிற்சாலைகள், கார் தொழிற்சாலைகள், இயந்திர தொழிற்சாலைகள் போன்ற கனமான பொருட்களை போக்குவதற்காக பயன்படுத்தப்படுமானால், தொழிற்சாலையில் கனமான சுமை மற்றும் நீண்ட நடைபாதை (ஒவ்வொரு காஸ்டருக்கும் 350-1200kg) காரணமாக, தடிமனான எஃகு பலகைகள் (8-12mm) தேர்ந்தெடுக்கப்பட வேண்டும். ) வெட்டிய பிறகு க TIG க TIG TIG TIG TIG TIG TIG TIG TIG TIG TIG TIG TIG TIG TIG TIG TIG TIG TIG TIG TIG TIG TIG TIG TIG
