All screw jacks in the series can be manually operated. The maximum load that can be handled according to the reduction ratio of screw jacks. Obviously, greater loads can be manually handled by applying further reductions to the screw jack or by increasing the radius of the handwheel.Hand wheels are available for Linear Power Jack so that it can be easily used for manual operation. Hand wheels are used for self-lock equipped Linear Power Jacks (Machine Screw Type) only. Because Linear Power Jacks (Ball Screw Type) and Linear Power Jacks (High Lead Screw Type) are not equipped with a self-lock, the input shaft may be reversed by a load, therefore, it is dangerous to use the hand wheel. Hand wheel efficiency is determined by the required torque for a specified load and the diameter of the hand wheel. Also, vibration and shock may cause self-lock failure, in which case a brake unit is recommended.
1. Note: The dark gray figures in the tables indicates operational restrictions due to thermal limits. 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 shaded dark gray, you will need to reduce duty cycle or choose the bigger size screw jack in order to allow effective heat dissipation.
