品名：礦用卷揚機
卷揚機又叫絞車，主要有下列幾種：
手動絞車
手動絞車的手柄回轉的傳動機構上裝有停止器(棘輪和棘爪)，可使重物保持在需要的位置。裝配或提升重物用的手動絞車還應設置安全手柄和制動器。手動絞車一般用在起重量小、設施條件較差或無電源的地方。
電動絞車
電動絞車廣泛用于工作繁重和所需牽引力較大的場所。單卷筒電動絞車(圖)的電動機經減速器帶動卷筒，電動機與減速器輸入軸之間裝有制動器。為適應提升、牽引和回轉等作業的需要，還有雙卷筒和多卷筒裝置的絞車。一般額定載荷低于10T的絞車可以設計成電動絞車。
液壓絞車
液壓絞車主要是額定載荷較大的絞車，一般情況下10T以上到5000T的絞車設計成液壓絞車。

Winch and winch, basically have the following several kinds:
Manual winch
Mounted on the manual winch handle of rotary actuator stop (ratchet wheel and pawl), can keep the weight in the location of the need. Assembly or ascension weight with manual winch should also set up the handle and brake. Manual winch generally used in the small weight, establishment conditions with poor or no power.
Electric winch
Electric winch is widely used in heavy work and the required traction larger places. Single drum electric winch (figure) of the motor through reducer drive drum, between the motor and reducer input shaft is equipped with brake. To meet the needs of the ascension, traction and turning operation, there are more than double drum and drum gear of the winch. Generally rated load is lower than 10 t winch can be designed electric winch.
Hydraulic winch
Hydraulic winch is rated load larger winch, usually more than 10 t to 5000 t winch hydraulic winch.
