Cantilever: ngwaọrụ na ngwa

Na ọdabara kreenu cantilevered isi dị ka onye aka na akwa kreenu na arụnyere na otu ụlọ, ma na a ala larịị. Nke a na ụdị na-arụ oké ewu ewu na ụlọ ọrụ. Nke a bụ n'ihi ya egosipụta ọtụtụ ihe, na ala na arụmọrụ.

The ụlọ ọrụ na-bụ-eji abụọ na ụdị jib cranes - mobile na anyịnya kreenu console. Roll bụ a console ofu aka ha ọtọ eku. Eku, n'aka nke ya, na-adịgide na ụkwụ abụọ na a iche iche drive. Nke a valvụ bụ ofu na mgbidi, nwere ike na-akpali tinyere ya. Nyefe emee na pụrụ iche na-eduzi site nke electric usoro.

The abụọ ụdị - Cantilever anyịnya. Nke a na ụdị ma mmasị ka ụlọ mgbidi, ma ọ bụ ka a ekwesị guzo tubular ma ọ bụ igbe-kọlụm. Mgbe a na kọlụm na-etinye na ntọala. Na omume na console nwere ike pivoted, ụdị na-akpọ "jib kreenu".

The ije nke ibu mere site hoists n'ịnyịnya na console na-aga ya. Ọ pụrụ ịkpali ma site a usoro arụnyere na onwe ya, ya mere, na-enyemaka nke cable traction, na-eduga na winch console. Nke abụọ ahụ na ọ bụ omume na-akpali ibu na a nnukwu iche iche nke gbapụrụ ọsọ. The console onwe ya na-akpali aka site n'aka a eriri, mgbe mgbe, n'elu ọgwụgwụ ya, ma ọ bụ ihe electric moto. Na nke ikpeazụ ahụ, ngwaọrụ ga-akpọ "cantilever kreenu electric."

Mgbe e ji dị ka a na-akwado kọlụm na tap nwere ike abụọ ogwe aka. Ọ na-akpọ a na-agha. Single Ogwe aka (otu-doo) cranes mfe ma dị ọnụ ala. A abụọ-agha nwere ike ebuli ibu karịa ịnyịnya ibu na idi ibu.

The feasibility nke na-eji dị iche iche nke cranes

1. Ke edinam na ị chọrọ ebuli igwe bụghị kwa arọ, ọ dị mma iji a kreenu console na ntuziaka ndoli na ntuziaka adiana nke console. Ndị a na ngwaọrụ na-abụkarị nnọọ adaba, dị ka mfe jikwaa.
2. Mgbe i na-ebuli ihe na-akpali ibu, ọ dị mma iji a kreenu na electric traction. Ọzọkwa, mma ma ọ bụrụ na ọ na-onwem na ndoli (electric ndoli maka akpụ akpụ ndoli).
3. Ọ bụrụ na, n'ihi na ihe ọ bụla na ihe mere, na mmepụta chọrọ pụrụ iche kwụsie ike, ọ kasị mma ime ka ibu site a abụọ-agha kreenu console.

Ke adianade do, nke a na ngwá bụ maka azụmahịa na na iji, ma ọ bụrụ na ọ dị mkpa, ọrụ ya na ụdị ụfọdụ nke kpọmkwem ọnọdụ. Nke a nwere ike ụba ogologo nke console, n'akuku nke adiana, elu nke ígwè, na nke ngụkọta ikike nke kreenu.
