SWL蝸輪螺杆升降機JBT8809-1998
SWL Worm and Worm Wheel Lifter
一、概述Brief:
蝸輪螺杆升降機是通(tōng)過蝸輪轉動螺杆完成提升，下(xià)降，推進等功能，廣泛應用(yòng)于機械，冶金、建築，水(shuǐ)利、化(huà)工等各項行業，具有結構緊湊，體積小，安裝方便、可(kě)靠性好， 穩定性高(gāo)，使用(yòng)壽命長(cháng)等優點。本系列升降機可(kě)自鎖，承載能力在2.51- -35t之間， ***高(gāo)輸入轉速1500/min.工作溫度在- 20'C一100"C之間。
Worm and worm wheel Liter performs moving up.down and forward by worm driving. It is widely used in field of machinery, architecture, chemistry etc. The lifer has advantages of compact structure,small size, easy installation .good roliability .high stability and long life span. It has self locking. The maximum loading capability is 2.5 to 35 ton and the miximum input RPM is 1500r/m.
The environment working temperature is botween-20'C and 100'C.
二、型式和(hé)标記Type and Earmark
2.1結構型式Structurat mode
