Hi all,

I dug the Tamiya forkie out and dusted it off for some photos today.

Here's the completed forkie and tethered controller.
The silver switch is for the red warning flasher and driving lights.
The controller takes 2 C-cell batteries.





What's under -

This is why this forkie is not suitable for a gritty work area,
note the exposed gears on the traction motor gearboxes.

There is also 3rd motor/gearbox above these,
that drives the up/down of the tines on the mast assembly.


 

The front section of the roll cage was removed,
to show Earl and the Tilt and Raise levers for controlling the mast.

These are just dressmakers pins bent to suitable positions,
then glued into the fabricated control panel.





Here's the view from the other side,
showing Earl, the control panel and the added mudguard/steps.





Just like real 1:1 scale large forklifts the forward visibility is very limited,
because of the amount of ironmongery in the way.





I spent more than a few years in heavy industry,
working around forklifts in a past career.

The Tamiya forkie probably comes in at about 20 to 30 ton lift capacity.
These are seriously LARGE lumps of moving machinery.
Here's my unofficial "safety rules" for working around these beasts:
  1. First rule of Safety - Keep out of their way. They have ABSOLUTE right-of-way.
  2. Second rule of Safety - NEVER assume that the driver has seen you.
  3. Third rule of Safety - ALWAYS have somewhere safe to retreat to if one comes your way unexpectedly. Beware of being caught in a "pinch situation" - find something very solid and immovable to "hide behind", never in front of.   
  4. Fourth rule of Safety - NEVER approach the driver unless you have been signalled in by the driver to approach the driving position. 
  Hey, they worked - I'm still walking around to tell the tale(s).

:glad:

Hi all,

I told you about the Tamiya forkie,
so that I could tell you about 2 more forkies.

Both of these are closer to a "scale-looking" forklift,
of about 3 - 6 Ton lift capacity.

These 2 would become the "main use" forklifts,
on 'Randim Stackum & Wrackem' once it neared completion.

There's a whole lot more to come in that layout story,
so I'll stop here and focus on these two forklifts.


Both of these are analog radio-control.

One of them is relatively common and still available,
the other rare, I haven't seen one since I got mine in 2008 or so.

Side by side they look remarkably similar,
and both were advertised at a very nominal 1:20 scale.


So what am I talking about ??
Meet the forkies -





In my best "boxing announcer" voice" -

In the green corner, on the left,
we have the 3-speed "Mini Jack" forklift,
that can lift to 150 mm height as shown above.

This is the "rare" one.
It also has operational headlight lights on the rollcage.


In the red corner, on the right,
we have the single-speed "IndustryFork Car" forklift,
that can lift to 110 mm as shown above.

This forklift is the "more common" one,
available under different names like "Engineering Fork" or similar.


This second forklift is fine for working in more open spaces,
but the first 3-Speed "Mini Jack" wins by a "long reach",
when it comes to precision control in tight operating conditions.
(like those on the RS&W)

The following photo shows the results of a throttle "blip" -





The smaller distance indicated by the movement of the front "Mini Jack" unit,
shows just how much more precise this unit is with its lowest of the 3 speeds.
Both units are roughly equal if top speed is used on the "Mini Jack" unit

The packaging is quite different,
but the shape of both the forklift and the controller is almost identical.
This makes them hard to tell apart when buying a large scale forklift.





The "Mini Jack" packaging has a lift up flap.





Here's a closer look at the forkie that is still available,
showing the pallet and the fold-up packing crate load.





And that's probably more than anyone wanted to know about "operational" large scale forklift trucks.

Hi Dave, all,

If anyone really wants to do something cool with the Tamiya forkie, then try this

https://youtu.be/bu-eC3ihZWY
or
https://youtu.be/DWDcn4aEDIE

This makes the Tamiya unit very suitable for some precision forkie driving. This type of gear wasn't readily available when I built mine back in 2008 or so.

The clunk when the mast is on the way down is easily fixable. It is caused by some burrs around a couple of tapped holes in the mast assembly. A few swipes with a file and some powdered graphite rubbed into the sliding faces in the mast fixes that problem.
