SWL, QWL points a worm screw lifts, lift the bottom plane of the entire installation shall be so consistent with the direction of the screw axis force. If you use inconsistent in the next, according to the catalog, please check the load chart. 2. Lift the motor drive shaft coupling when direct screw lift, to adopt flexible coupling for rotation to be flexible. 3 lifts using lithium grease lubrication, the new machine has been added grease, use regular fuel mining, oil change beginning with six months should be cleaned once. 4, the simultaneous use of multiple lifts shall adjust screw stroke, consistent force after mounting to prevent uneven load generated early damage. 5 lifts installed after the load should be carried out gradually loaded. Under normal circumstances, the operation should be smooth, non-impact, noise and loopholes and so on. 6, on the question of the use of lifts found, should make a detailed record of the specific technical parameters and related information, please read the catalog of non-standard screw lift, or contact our technical department. 7, supporting the use of lifts host manufacturers must be incorporated into the host of the use of points to the instruction manual in order to ensure the credibility of the host to use. SJA spiral screw lift unique selection square casing design, material selection ductile iron, a substantial increase in the strength and performance of the housing screw lift manufacturers, as well as in the high and widely used at low temperatures. Use a square tail cover design screw lift manufacturer, does not control the rotation of the lead screw.
