5. Heavy Duty Screw Jack MSZ

Main Catalog - 9350 100kN

MSZ-100 Rotating Screw R 100kN

base line deepdeep deep x = calculated spindle length (chapter 4.8) + 10 mm System components are presented in chapter 14A minimum of 10mm safety clearance is requiredbetween the nut + gearbox / nut + end mounting to prevent dammage due to possible overun. Selection, calculation, checklists and order code: see chapter 4

Technical data S and R Capacity diagram stat./dyn. S and R

Max. pressure/tensile force static- 100 kN (10 t)Max. drive shaft speed- 1800 min
-1 [kN] load N = Normal speed L = Low speedThis diagram indica-tes the mascimum capacity (under opti- mal conditions). Where duty or load are near upper limits we recommend the selection of a bigger gearbox.The maximum dutycycle is affected by many factors: e.g.: lubrication, environ- ment temperature, bellows, etc.
2) (higher on request)Screw dimension- Tr 50x8 Gear reduction- 8:1 (N) / 32:1 (L) Material of box- GG grey cast Lubrication- grease Weight of lifting gear- 33 kg Weight of spindle/m- 13 kg Drive torque M
3)5) G [Nm]- F [kN] x 0,78
3)5) + M
L (N-Normal)- F [kN] x 0,25 + M
L (L-Low)Starting torque- drive torque M
4) G x 1,5Idle torque M
L [Nm]- 1,68 (N-Normal)- 1,02 (L-Low) Important notes
1) 2) - For bellows or spiral spring extensions: see chapter 4 - Tr50x8 is standard, also available: 2-pitch, INOX, left-handed, larger diameter spindle Tr60x12 (only for R version)
static dynamic 3) 4) - Factor includes efficiency, ratio and 30% safety
basis: 20°Coperating time in % per 10 ‘ 5) - May be higher in new condition - At spindle pitch of 8mm
