1 ton manual worm gear screw jack for lifting. Manual screw jack (hand wheel screw jacks, hand crank screw jacks, hand operated screw jacks) is driven by a hand wheel or crank or handle. The best advantage is suitable for heavy load, low speed, low service frequency. Our manual screw jacks have different configuration form and assembly type,and the lifting height can highly customized according to users' demand, low cost and easy operation.
Hand Wheel Screw Jack is very popular for all kinds of applications.So when to use it?
1. In case of power failure, screw jacks can be moved manually via a handwheel. To do this, one input shaft shall be available on the screw jack for the connection of the handwheel. If a brake motor is used, the brake shall be un-clamped firstly, so to allow for movement.
2. Light load, low duty cycle, low-speed application.
3. Intermittent positioning applications
* 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.
