    Default 1/14 Yale Forklift

    I've been wanting an rc forklift for a pretty long while. Years ago many of the great 1/14 scale modelers around built some, and made warehouses to go along with their semis. I had picked up a static Bruder Linde H30 about a year ago, but it's been pretty slow to plan out converting to rc. Then with so much time spent watching Loading Wars / Loading Kings it looks like even more fun.
    However even the Carson Linde h40 is more than i want to spend to get one here. Do i really need one... Fork yeah!

    I just picked up the NewRay Yale with pallet rack and some cargo. I sometimes run Yales at work, and it's a little bigger so i should have some room to work. It's based on something in the Yale Veracitor VX series, think looks really close to the VX50 to VX70s.





    They come set up as 3 channel binary control, runs on 3aa batterys, 9v in the tx. Not that impressive, but still kinda fun. I can see why the old reviews on these weren't great when they were still yellow and Yale branded. It had weak steering one direction, then it gave out within a week of getting it. Wasn't planning to upgrade until after the Lebanon IN meet, but it changed those plans. Nothing too crazy to start with because rush job, just parts i had on hand. 6ch rx, metal gear servo, 2 cheap escs, a blinky rotator light, some 3mm leds, 4aa rx pack.

    I went back to look again at the several rc sparks videos of upgrading the Carson h40 Linde they run on the Loading stuff and went "similar but different".

    One really nice thing about these Newray vs the Carson forks is the mast lift has retract springs instead of working on gravity, so i don't need to add weight to the fork rack that would take away from how much weight it can lift and still steer with a load on.

    The small cheap no-name brushed escs are a good fit, as it's only pushing 130 motors. Steering servo took a setup i wasn't fully happy with and will probably change if i made another, but it kept it all below the battery rack and might even get me some high speed wobble.
    I used a flysky "fs-x6b" rx, and it just happens that board uses the same mount spacing as some posts in the forklift. I don't actually reccomend it since you basically have to make power and ground bus and connect individual signal wires to evrything. I like plug&play rx options better.

    Battery lives up in the forklifts counterweight, i knocked out the seperators and forward wall to shove battery through. Also hogged out the battery cover stiffeners a little so i wouldn't need to worry about pinching a wire. Stuck some micro JST connectors on because they look pretty similar to scaled down Anderson PowerPoles.

    Had to put a yellow beacon on the ROPS... Safety Third.
    It's not right to ever try to be a spotter for a forklift without having lights shining directly in your eyes, so i drilled out the square housings for some 3mm leds with some chrome paint, all wiring routed down a channel in the ROPS and tapped the yellow beacons harness for power with a resistor. White lights & beacon come on when model turned on.

    It takes 3 screws to split the body off the chassis, and now disconnecting Light and Battery connectors to completely remove it.

    Dropped a bruder figure in the seat, probably needs a seatbelt.
    It's got a cup holder on the bulkhead, so i opened that up and shaved the bottom of a dollhouse coke bottle. Had to pop the cap and drill the mouth of the bottle.

    Think i'm probably going to need to order some decals for this after i paint the black parts. Could use some weathering.

    Later i'll set up another servo for rack tilt, and start working out how much ballast i'll need.

    I'd thought about trying to go moving steering wheel, but don't think there's enough room to keep it looking right. I'd either have to lose the steering column, or put a bulky box on the bulkhead.

    Still looks pretty similar to stock, wish i had the yellow Yale version, but i think i've got a pretty good plan for a company livery based off the orange-red





    I should have screwed on the battery cover, but i was in a hurry with those pics

    I was hoping this might be of interest to more of you. These really let you go nuts flexing your scaleness

    Found a couple logos i'm trying do decide between, fixed the stripe, made a bigger rack, made some wood pallets, scrounging some cargo...

    Looks great! I have one of those same forklifts and was waiting to see somebody make a more 'hobby grade' out of it. Be interested in seeing how you setup the esc's and steering.

    These pics from this Lebanon IN meet have been stolen from wolfws6. Thank you.

    Somebody brought these docks


    They also had one of the old Robbie forklifts, so i got to check that out a little.

    Anyway, i snuck over and put some stuff on them to operate my fork. Turns out 'loading docks' are not good at being 'warehouses'.
    I also need to mod a little more to crank my steering even tighter, it's much better than stock, but for tight use it probably needs somewhere between drift car and shopping cart.



    Huh, that one is not my fork. Mine has the full Yale blackout stripe.


    -

    Behold the ugly!!!

    I had a lot of words written out explaining this, then while i was dropping keyboard off screen to reread something, it tried to post. Token expired. Grrr. "Not today Lao Che!"







    I'm going to bed. I'll fix an edit later

    I make NO claims this is the best way to mod one. This is my way, with only what i had on hand, on a tight schedule. "Yay the forklift is here! I will not mod anything on it until after the meet. Ok it needs tighter steering. I will not mod the electronics until after the meet. oh expletive the steering died. Panic and upgrade it really fast!"

    I pulled the stock steering gearbox out, hogged out the fender liners for tire clearance for more angle. I should have also trimmed the top steering retainer plate to get max angle. I matched servo horn length to the steering gear pin-fulcrum, made a J shape brass thing that pokes into the draglink. Draglink center hole was drilled to size for the brass J to take out the slop it would have had. I probably should put something like a fender liner around the servo and fwd side of fenders to help keep stuff out

    Hoist&drive are stock, i just added escs. The top of my gearboxes have 'H' and 'D' written for 'Hoist' and 'Drive' to make assembly and later Mx easier knowing which esc does what. I took the power switch wires from one esc and hooked it up to my stock power switch on bottom. I pulled red wire out of rx plug on other esc so it's not going to have 2 bec fight and free the magic smoke. Both esc hook up parallel to the battery.

    For Rack-Tilt this way, the body needs modified a little. i removed the U shape piece with the "rack cylinders" and dumped the springs. I cut slots in the rack cylinders, and drilled holes in the "rack tilt actuator rams", passed a rod through the actuators to be a crossbar. Make the rack cylinders silver or chrome. Found a place to stick a servo on the hoist/drive gearbox, made a linkage with a Z-bend and a loopy to hold the crossbar. I need to put a sleeve or something on the crossbar to keep the linkage from moving sideways. The body had some supports that i had to cut for clearance of my crossbar, study the pics, be sure to keep the parts that hold the U shape. Make sure crossbar isn't too long and binds on outer sides of body.

    *** added ***. If i were smarter my rack tilt would probably be done with a continious rotation servo mounted vertically with a linkage running to the same style actuators. This way when moved it would just cycle rack fwd and back, and should hold location where ever stopped. My current setup is normally 'about' vertical, until you push and hold rack one way. Or i could have put it on ch 5/6 and configured it as a Pot channel.

    I also opened up the slot in front of body where the hoist string exits and travels up to ease body remove / install.
    ***

    Again, pretty sure i wouldn't suggest this RX since it was made for quads with flight controllers, but it works to make Power and Ground busses to connect all outputs, then take a signal wire to each component. Adds unnecicary complexity. But i had that Rx, and it didn't work for a TTTT i wanted to make.

    Cram everything you can under the rx board. Make sure the escs aren't going to interfere with the steps in body. Stuff the extra wiring up under the seat when installing body. If you cut out part of battery compartment, take the door off to help see what binds as it closes.

    Think it through, test fit often, don't do something you can't undo unless you're sure.

    I think i mentioned cutting out the 3aa battery rack to hold a 4aa rx pack. I know it could take bigger mAh lipo than these nimh. It's got some runtime, but i'm not trying to make driving this a job.

    I'm also going to put some lead in the chassis later. Won't go too crazy, it's only like 130 size motors with a 700mAh battery.

    Looking good! I'll probably start a DIY project soon.
    Thanks for the inspiration. :)

    All you guys who work with this scale heavy equipment: I am always so impressed. Such ingenuity.

    I just saw that RC4WD has released a forklift as well, which is hobby grade (with a price to match).

    Thank you gentlemen! I'm glad it's interesting and providing some inspiration.

    Cool, i hadn't seen the Forklift from rc4wd. I'll have to check it out.

    I wasn't sure if the forklift would actually be up to the scale standards of everyone over here. With the reception of my dumptruck, I'm pretty sure my Dragline equipped Michigan Crane isn't.

    I was trying to set up some stuff to make a funny video and realized i need to figure out how to lock the hoist clutch. I also need to add some ballast weight.

    The world has been too serious, take a couple minutes to try to have a laugh.

    Here's a forklift operator who only works with pallets trying to learn to handle paper rolls.

    Yes, this is a joke about the reaction of Americans to the Covid-19 flu. I don't know why they picked Toilet Paper as the scarce commodity. 2020 is going to be an interesting year.
