I'm a student from the KULeuven in Belgium and I'm doing some research on developing a hydraulic energy recovery system. I've already modelled in Matlab/Simulink (mathematic program) a hydro-pneumatic system that recovers braking energy. But now I want to model a system that recovers energy from lowering a load.
I'm using two one-way cilinders.
The pump must be driven by an ICE (internal combustion engine). The energy that is recovered doesn't have to be stored in a battery but in accumulators so I can use the recovered energy for lifting a load.
I'm looking for a hydraulic scheme for this energy recovery system and maybe some formulas. Any help would be most welcome!!!

Some Linde turret trucks are equipped with regenerative lowering. I'm told that it won't work on a standard forklift truck because if you are lowering the forks empty the regeneration effect overcomes gravity and the carriage stays in the air. You need a turret truck to do that because of the excess weight of the turret head.
Hi guys i have recently been informed that STILL have got an energy recovery system on the lowering of their new reach trucks also on some man up trucks.
some research has been done on this subject and from what i could understand systems requiring gravity to perform part of the process are not well suited for "regen" recovery. anything done to restrict or redirect oil flow adds heat which is all lost energy as well as being detrimental to the system itself. i hope you can figure this out, it could potentially lower the horsepower requirements for (ice) systems and save energy as well as money. i would say the environment would benefit but i beleive (global warming) is a GIANT bunch of B.S.
