yard forklift
I recently started building a yard forklift, the goal is to have a set of forks for skids and regular cargo, and an add on grapple for containers. I started this because I was frustrated with the newray conversion I had, it basically lacked power and controlability, this should eliminate that!
So far the specs are: tamiya f350 rear axle with aluminum lockouts stock tamiya semi tires venom creeper transmission planetary gearbox for lift motor duratrax chains and sprockets in the lift system custom machined mast brass chassis rc4wd 80t motor hitec 645mg steering servo hpi sf1 1/4 scale servo for tilt on the mast venom esc and tamiya esc to run the motors heres a starter pic....... |

Re: yard forklift
Looking good. Remember to keep your center of gravity as low as possible, any way to lower that transmission or use one that sits lower? Also add as much weight to the chassis as you can but keep it as low as you can.
When they talk fork lifts you will hear the "stability triangle", that is the imaginary triangle that runs across the front axle and back to the center of the rear axle. Your load weight should never be outside of that. Last edited by Claus; 05-14-2013 at 02:43 AM. |

Re: yard forklift
Thanks for the info, the transmission itself looks high but the motor bolts on at the bottom frame rail. The lift motor and batteries also mount low on the frame so most of the weight is below the top of the tires.
I had to mount the tranny like that so the drive shaft could come in over the top of the gearmotor that runs the mast. Once everythings done I plan to add a "tray" tot eh bottom of the frame and fill it with lead stick on weights as necessary to lover the CG and balance it. |
