Determination of type
1. Type 1 = Screw jack with translating screw
Type 2 = Screw jack with travelling nut
2. Size = 2.5, 5, 10, 15, 20, 25,35 (×10KN)
3. M = Low worm gear ratio with single start lifting screw
P = High worm gear ratio with single start lifting screw
4. Direction of lifting screw
A = Upright
B = Inverted
5. Lifting screw end execution
I = Column end
II = Top flange
III = Threaded end
IV = Clevis end
6. Stroke
= mm
7. Bellows
1. PVC bellow
2. Other bellows, specify in order
8. Options
F = Locked against rotation
Example
SWL 2.5 - M - 1 - A - II - 250 - F
