Girder kreenu: nkọwa na harateristiki

Na niile na ngalaba nke mmadụ ọrụ girder kreenu nwere ike iji na-akpali ibu. Ọ bụ a na-ebuli usoro ewekarị on hoists (Trolley), nke na-akpali tinyere akwa girder.

Mbanye na ndoli kreenu doo

A kreenu usoro maka na-akpali akpali bụ electric mbanye na a cylindrical ma ọ bụ conical akwado wiil. Cylindrical wiil na-eji ikpe ebe njem nke ibu a rụrụ naanị na a ogologo akara. Tapered amị girder kreenu hiwere isi rails na-eji ma ọ bụrụ na ụzọ nwere curved okporo ígwè òkè. The actuator nwere ike ahazi dị na iche iche imewe atụmatụ. Trolley bụ a etiti Ọdịdị nke a na-akwado na-agba ọsọ ụkwụ na-adịru ibé. Ọ ike a usoro Lifting - electric ma ọ bụ na ntuziaka, na-enyekwa a limiter arụ ọrụ nko ngọngọ.

Types of doo cranes

Dabere na imewe atụmatụ nke girder cranes nwere ike na-akwado, na-ekowe na gantry. The mbụ ụdị bụ a Ọdịdị n'ịnyịnya na overground ụgbọ okporo ígwè track - vetikal posts eme ihe dị ka na-akwado nke na-n'ịnyịnya okporo ígwè na eri.

Gantry aghụghọ na-eji nanị maka njem nke multi-ton ibu. Ha na-ewetara a Ọdịdị nke kwụ ọtọ na-akwado (ike nke na-akpụ akpụ na a kwụ ụgbọelu) na kwụ ibé. Ha akporo - ibu njikwa na-ewu ụlọ ọrụ.

Girder cranes na ọganihu

A pụrụ iche ebe ke ewu na saịtị enyene a ụlọ elu kreenu na girder ọganihu. Ọ bụ a ot imewe maka loading na ebutu, nzukọ a na-ewu na-arụ ọrụ dị iche iche na saịtị. The ọganihu nke kreenu dị otú ahụ truss zita, akụkụ anọ ma ọ bụ square udi.

The ọganihu a dịpụrụ adịpụ elu na nke ala belt. Na ala iru ugbo Trolley Nkea site na actuator. Mgbe ụfọdụ, o nwere ike kpọgidere tightly na okporo osisi. Na nke a, na ije nke ibu na kwụ ụgbọelu na-ewe ebe site na-akpụ akpụ na ọganihu tinyere ndu onwe ya.

The doo nwere ike positioned ịgbasapụ ma ọ bụ na ihe n'akuku nke ^banyere 30-45. Kreenu girder na ọganihu nwere ọtụtụ uru. Firstly, ọ bụ ngwa ngwa ije nke ngwongwo na kwụ direction.

Njirimara doo cranes

Dabere na ike kreenu doo nwere ike kenyere mbụ (ruo 5 m), nke abụọ (50 m) ma ọ bụ atọ (320 tọn) otu. The winch na electric mbanye na-eji dị ka-ebuli usoro. Ọ bụrụ na okporo osisi nwere àgwà nke ọrụ kreenu ezi elu, ọ na-onwem na abụọ na-ebuli usoro: isi na sekọndrị. Ihe ọzọ dị mkpa e ji mara bụ obosara nke kreenu doo na-adịru.

girder kreenu akara usoro

Kreenu akara mgbe ground. Analọg akara dị na ozugbo visiniti nke onye ọrụ, ejikọrọ na wires na-ebuli na njikwa usoro. Remote - ọzọ usoro nke akara. Nkọwa girder kreenu isiokwu na kọmputa, nke, n'aka, na-achịkwa site na ọrụ. Cranes achịkwa si ụlọ na-eji nnukwu ulo oru ụlọ ọrụ. Driver, emi odude ke tagzi, ejisie dum usoro nke njem.
