2.5 ton Stainless Steel Screw Jacks

2.5 ton Stainless Steel Screw Jacks application of high-grade steel and innovative technology, this lifting solution can absolutely be used for steel hydraulics construction, food industry as well as in explosion-proof areas. For use in corrosive environments, a special lifting element series has been developed. Since neither standard paintwork nor coatings afford lasting protection, all the components that come into contact with corrosive media have been made from corrosion- resistant materials.

2.5 ton Stainless Steel Screw Jacks Key Features
1. Model JSS-2.5T,Maximum static load 2.5 Ton. 
2. Lifting screw sizes Tr 30x6. Customized stroke length.
3. Translating, anti-rotation (keyed) and rotating screw configurations.
4. High ratio 6:1, Medium ratio 12:1, Low ratio 24:1.
5. The 2.5 ton stainless steel screw jacks can be connected together in systems so that multiple units can be operated and controlled together.  
6. Hand crank manual operation, Electric motor driven or both together.

2.5 ton Stainless Steel Screw Jacks Specifications

* 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.
* Conditions: Duty cycle 20%/h or 30%/10min, 20 °C ambient temperature. 
* Gear Ratios: H: high ratio, L: slow ratio.
* Nm: Input torque required, kW: Input power required.
