Example of selection Use two sets of jacks in the following equipment, and lifting stroke is 300㎜ in a minute, please select the jack model number. In addition, the usage load of one is 30KN, and the jack is self lock. (1） Select JA type from the list of products. (2） According to basic specification of JA (E-14), select JA050-H whose nominal capacity is 50KN. (3) It is suitable since 50KN at operation speed of −0.3m/min is permissible operation load per load speed chart (E-17). (4) Observe curve 2 of permissible axial direction load (E-20) ηf＝1 L＝530 it is suitable since permissible axial...

Permissible load of jack while rest and operating is equal or not. permissible load at rest is more than 1.2-2 times of operating load. R e s t The force to rotate toward same direction as worm wheel is acting on screw shaft. Function of whirl stop is to stop rotation of screw shaft. and to change that force into thrust. Can hold 1.2-2 times more Why need screw shaft whirl stop Guard against rotate together must have lock pin What is the difference between trapezoid screw and ball screw? Trapezoid screw has self protection (self-lock) function. It has excellent safety such as prevent...
