Safety nuts on screw jacks work 25 kN in rotating nut design worm gear jack. High-performance worm gear screw jacks with long safety nut are used for adjusting the height of aircraft maintenance platforms. A Safety Nut Provides Safety Roles: In the event of excessive wear on the nut thread the load will be transferred from the standard nut to the safety nut. This will also provide visual wear indication as the gap between the safety nut decreases to zero as the standard lifting nut wears. In the unlikely event of catastrophic nut thread failure the safety nut will sustain the load.
The safety nut can be used to monitor the wear on the lifting screw threads on the lifting nut (rotating screw jack) or worm gear (translating screw jack). As the lifting screw thread on the nut / gear wears the gap between the safety nut and the nut / gear reduces to zero. This allows for wear monitoring and scheduling of preventative maintenance before parts become worn out.
Safety features that can be employed include safety nuts, brakes and wear monitors. The Jacking systems lifting the aircraft access structure (tail dock). Railway Carriage Lift All railway carriage bogie drop and jack systems are designed to be extremely strong, simple and very safe. Metric machine screw jacks for the lifting mechanism on this system installed.
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.
