回柱絞車

回柱絞車主要供煤礦井下回柱放頂之用。特別適用於薄煤層和急傾斜煤層采煤工作麵，亦可用來拖運重物和調度車輛。
絞車配有隔爆電氣設備，可用於有煤塵及瓦斯的礦井。

Back-pillar winch is mainly used for back-pillar roof caving in coal mine. It is especially suitable for thin coal seam and steeply inclined coal seam mining face. It can also be used for hauling
heavy objects and dispatching vehicles.Winches are equipped with flameproof electrical equipment, which can be used in mines with coal dust and gas.

回柱絞車可用於環境溫度-10°C—+40°C，相對濕度不超過95%（+25°c），周圍空氣中的甲烷丶煤層和硫化氫丶
二氧化碳等不超過《煤礦安全規程》中所規定的安全含量的礦井中；工作製為低速重載非連續型。

Pillar winch can be used for ambient temperature - 10 C -+40 C, relative humidity not exceeding 95% (+25 c), methane, coal seam and hydrogen sulfide in ambient air.Carbon dioxide and
other coal mines which do not exceed the safety content stipulated in the "Coal Mine Safety Regulations". The working system is low-speed, heavy-duty and discontinuous.

電動機安裝在底座上通過聯軸器與蝸輪減速機聯接，動力通過一對齒輪傳動給圓弧麵蝸杆、蝸輪，由蝸輪軸上的小齒輪經中間過橋齒輪傳動大齒輪帶動卷筒，卷引鋼絲繩進行工作。
