200 kN Cubic Screw Jacks

200 kN Cubic Screw Jacks Key Features
1. Maximum static load 200 kN or 20 Ton. Maximum dynamic load 85 kN or 8.5 Ton.
2. Lifting screw sizes Tr 70x10. Customized stroke length.
3. Translating and Rotating Screw configurations, Anti-rotation (keyed) design option.
4. High ratio 10:1, Low ratio 40:1.
5. The 200 kN Cubic Screw Jacks can be connected together in systems so that multiple units can be operated and controlled together.  
6. Manual operation, Electric driven or both together.

200 kN Cubic Screw Jacks Specifications

1. Note: The dark gray figures in the tables indicates operational restrictions due to thermal limits. Static only (dynamic not permitted). Selection of screw jacks using these figures should only be carried out in consultation with our engineers. When your selection is made within the areas dark gray, you will need to reduce duty cycle or choose larger model screw jacks in order to allow effective heat dissipation.
2. Conditions: Duty cycle 20%/h or 30%/10min, 20 °C ambient temperature. 
3. Gear Ratios: H: high ratio, L: slow ratio.
4. Nm: Input torque required, kW: Input power required.
200 kN Cubic Screw Jacks Design and Configurations
* US: Upright configurations, translating screw.
* IS: Inverted configurations, translating screw.

UK: Upright configurations, keyed anti-rotation screw.
IK: Inverted configurations, keyed anti-rotation screw.

UR: Upright configurations, rotating screw with lifting nut.
IR: Inverted configurations, rotating screw with lifting nut.
200 kN Cubic Screw Jacks Stroke
Example: 300 mm stroke, lifting screw travels 300 mm, then we will make the lifting screw length=stroke+housing height+screw end length. All lifting screws stroke is made following your requirements. Special lifting screws design, please consult us!!
200 kN Cubic Screw Jacks Gear Ratios
* H: high gear ratio 1/10, lifting screw travels 1mm per turn of input shafts revolution.
* L: low gear ratio 1/40, lifting screw travels 0.25mm per turn of input shafts revolution.
Customized medium speed ratio 1/20, lifting screw travels 0.5mm per turn of input shafts revolution.
200 kN Cubic Screw Jacks Lifting Screw End Conditions
Standard lifting screw end conditions such as top plate, clevis end, threaded end, plain end, spherical hinge, forked head. Can make lifting screw ends following your required. Before ordering, please send us your special design drawing of lifting screw ends.
