i am building a 6X12 hydraulic dump trailer. i want to keep the hydraulic ram from extending below the frame and losing ground clearance. in order to do this i need to make a bell crank to be the tilt mech. for the bed. any design ideas out there? i could "trial and error" my way through it but would rather not. thanks in advance. btw it will be rated at 10,000 lbs.
