As part of a project I am looking for a supplier of vertical linear guide systems, but that would be slowed down. Let me explain.
The project:
I have to move a sheet metal box (about 500 x 350 x 100) carrying equipment, with a total weight of about 5 Kg, vertically, over a stroke of about 400 mm
But I have to be able to stop it at any level, without it falling under its weight, hence the idea of braking...
The movement must be flexible, the whole thing can be handled by hand
Has anyone designed anything like this? Or does he know a supplier?
Does this operation have to be repetitive? If so, you can buy a garage door opener system and adapt it and adjust the motor stroke so that it travels only 400mm.
A gas spring plus a locking system => principle of what we almost all have under our office chairs. No or little effort during handling provided that the choice of cylinder is well made.
For such a low mass I will use a trapezoidal screw for its irreversibility with bronze or nylon nut (you just have to put a handwheel at its end so that the operator can rotate it, no need for blocking, the irreversibility of the screw is enough if not weak enough, as well as a guide to accompany the mvt,
For the choice of guidance... a Hepco type roller guide is good because it is simple to integrate on an aluminum or steel tube without machining (constrained by ball pads).
