For starters i am a complete noob when it comes to hydraulics so any advice would be greatly appreciated. I am mason contractor based out of NY with an itch to design and build my own equipment.

I am looking to fabricate some mast climbing scaffolding for our operations meshing some known technology that has already been on the market with a new design for the rest of the scaffolding units.

These particular scaffold units raise up the vertical masts by means of a cogged wheel that engages the mast, which is turned by a hydraulic motor of some sort and is powered by a small Honda gas engine. The scaffold "Power Units" are twin mast and each PU has 1 Honda motor, & 2 cogged wheels. 1 Wheel per mast and are perfectly synchronized. These PU are then bridged together to adapt to the buildings dimensions.

I need some help with designing a hydraulic system that can run off this small hp Honda engine. That can run 2 hydraulic motors perfectly synchronized and be a push button operation. The motors would have to turn very slowly and have plenty of torque. Ive been researching LSHT Char Lynn T brake motors for this but im open to suggestions. I will post up plenty more pictures of the power supply and hydro system from this Bennu model.

This particular design has seen alot of bad press over its lifetime due to collapses mainly from the flimsy mast sections. However the lifting mechanism is superior to the competitors. My goal is to apply this lifting mechanism to a more robust platform. That being said im having a hard time getting to the actual mechanics of this Bennu PU systems components. I dont want to copy cat. Im also not looking to market what i build. This will be for my own use. Cost is a big factor in this endeavor and i would like to find a low cost solution to this. Thanks very much for any advice. If i get some interest here i will post loads more info.
