Thank you all for your replies. The current system uses hydraulic cylinders to raise/lower the frame. We are trying to reduce cost by looking at alternative actuators, but it's starting to look as though the hydraulic system is in fact the most cost effective.
Hello Everyone
I'm a long time reader, first time poster to Eng-Tips.
I'm looking for a gearbox for an application we have which involves lifting/rotating a heavy piece of machinery on transportation device. I'm not entirely sure something like this is possible or, at the very least, feasible...
