The layout of the jacks is attached.
The operating mode of the jacks is one cycle with a stroke of 20 mm in 90 seconds, during a working shift of no more than 8 hours and one cycle with a stroke of 710 mm 1 time in 8 hours
Operating conditions: Operating temperature from +10 to +35 degrees Celsius, there are no aggressive media, the presence of dust, dirt, abrasives, the presence of corrugation on the screws is preferable
The real dynamic force on the nut when moving, the real static force on the nut when moving: When the nut moves in both directions, the force on the jack will be 10 kN.
At the greatest distance of the nuts from the gearboxes of the jacks, in a stationary position, the external force increases to 700 kN for each jack. The screws of the jacks with this force work for compression. In other words, the jack must hold a force of 700 kN without movement.
The maximum traverse stroke is 710 mm
The required linear movement speed is about 18 mm/s
Optionally, we may be ready to consider offers for electric motors selected on the basis of the data provided.
Stainless steel screw is not required
Preferably the gear ratio RL 1:36
Fixing the jack is possible in any way (jack housing with threaded holes FF or with through holes FP)
For the position of execution 2 when choosing the jack, we did not see the difference in the mounting positions left LH and right RH. It is necessary to select and offer on the basis of the attached scheme, attach a justification for the selection to the proposal.
We are ready to consider alternative designs with mandatory application of overall dimensions.
