Chotchinga chopanda chotchinga chopanda chotchingandi mtundu wa chotchinga-free handrail anaika m'malo a anthu, monga zipatala, nyumba zothandiza anthu, nyumba okalamba, mahotela, ndege, masukulu, mabafa ndi madera ena ndimeyi, kuthandiza olumala, okalamba ndi odwala kuthandizira kuyenda ndi kupewa kugwa mankhwala.
Zotchinga zopanda malire zoletsa kugundana zamanja zimagawidwa m'masitayilo awa: 140 zoletsa kugundana, 38 zoletsa kugunda, 89 zoteteza kugundana, 143 zoteteza kugundana ndi 159 zoletsa kugunda. Tiyeni tiwone zomwe njanji iliyonse ili nayo. Malo oletsa kugundana ndi 38mm m'lifupi. Mawonekedwe ake a cylindrical amapangidwa molingana ndi kugwirira koyenera kwa kanjedza kwa munthu. Ndizosavuta kugwira ndikugwiritsa ntchito. Maonekedwe a pamwamba amawonjezera kukangana kuti kanjedza isanyowe. Kugwira mosakhazikika ndikowopsa. Komabe, chifukwa cha m'lifupi mwake laling'ono la handrail, malo okhudzana nawo ndi ang'onoang'ono, kotero sangathe kusewera bwino zotsutsana ndi kugunda pamagalimoto, mabedi oyenda, njinga za olumala, ndi zina zotero. Ndizoyenera kwambiri ku ntchito zokalamba za anthu ammudzi, ndipo zimagwiritsidwa ntchito poyenda thandizo.
M'lifupi mwa armrest yolimbana ndi kugundana ndi 89mm, mawonekedwewo amapangidwa ngati mawonekedwe opindika ngati dontho, ndipo malo ogwirizira ndi akulu kuposa amitundu 38. Komabe, chifukwa cha vuto la mawonekedwe ake, zotsutsana ndi kugunda ndizofala, ndipo nthawi zambiri zimagwiritsidwa ntchito kubisa mphamvu ya chikuku. Ngati amangogwiritsidwa ntchito pothandizira kuyenda kwa anthu , ichi ndi chisankho chabwino kuchokera ku maonekedwe a aesthetics ndi zotsatira zogwiritsira ntchito. Nthawi zambiri zimagwira ntchito ngati malo ochitira anthu olumala.
Malo oletsa kugundana awa ndi 140mm m'lifupi ndipo ali ndi mawonekedwe otakata. Kuchita kwachindunji kwa mawonekedwe awa ndikuti zotsatira zotsutsana ndi kugunda ndizodziwikiratu. Chifukwa cha mawonekedwe ake amitundu yayikulu, imakhala yosiyana kwambiri pakusankha mitundu, ndipo imatha kusankhidwa ndikusinthidwa malinga ndi mawonekedwe onse okongoletsa. Ndizoyenera kwambiri pulojekiti ya handrail ya ndime ya chipatala.
M'lifupi mwake malo oletsa kugundana ndi 143mm, komwe ndi malo opumirako oletsa kugundana. Ndizofanana ndi kuphatikiza mwachindunji zitsanzo za 38 ndi zitsanzo za 89, kotero ubwino wake ndi kuphatikiza ziwirizi. Popeza pali zisankho zambiri zowonjezera, kusankha kwa mtundu wamitundu kumakhala kosiyana, koma kumakhala kovuta kukhazikitsa. Nthawi zambiri zimagwira zipatala ndi nyumba zosungirako anthu okalamba.
Malo oletsa kugundana awa ndi 159mm m'lifupi, ndi chogwira mozungulira kumtunda ndi gulu lolimbana ndi kugunda la nkhope yayikulu pansi. Izi ndizophatikiza 38 zotsutsana ndi kugundana ndi zida za 140 zotsutsana ndi kugundana, zomwe zimapangidwira mu chidutswa chimodzi, mosiyana ndi zida za 143 zotsutsana ndi kugunda zomwe zimaphatikizidwa mosiyana. Kupumira kwa mkono kumeneku kumapangitsa kuti munthu azigwira bwino ndikuwonjezera malo odana ndi kugundana, ndipo zotsatira zotsutsana ndi kugunda zikuwonekera kwambiri. Ndipo kusankha kwamtundu kumakhala kolemera kwambiri, ndipo kumatha kufananizidwa mosavuta ndi mitundu yosiyanasiyana yokongoletsera. Nthawi zambiri imagwira ntchito m'malo omveka bwino monga zipatala ndi malo ophatikiza azachipatala ndi okalamba.
