How a trailer is made

Twenty-five different components, many of them in several variations, are the ingredients needed to produce one KoloFogo trailer.

No, we don’t want to brag about how much we have to handle, we just thought it would be interesting if you knew how many materials and components need to be put together to make one of our trailers. The fact is, it doesn’t seem difficult at first glance. You’d think: a few bent and welded pipes. Believe me, it would be a lot easier for us – if it were so easy 🙂

For everything to work as it should, and for it to last a long time and be reliable, all the parts of the frame need to be put together from tubes that will stand up to calculations and tests, but at the same time won’t weigh a ton. We don’t bolt it all together to make it squeak and rattle in the field, but we build it honestly.

Sure, we make it the old-fashioned way, but we want to make sure the trailers leave us with 100% quality. And because we manufacture here, we can also offer all our customers fast service.

So what do we actually put together? If we were writing a recipe for a KoloFogo trailer, it would be quite a respectable list, but you can judge for yourself:

9 types of aluminium tubes (by diameter and wall thickness)
2 types of aluminium bars (by diameter)
1 type of aluminium steel with rounded edges
4 types of stainless steel tubes (by diameter and wall thickness)
8 types of aluminium cut-outs
2 types of stainless steel cut-outs
18 original smaller couplings
2 original larger couplings
1 original tow bar bracket
3 types of CNC machined aluminium parts
2 types of plastic sliding bushings
1 type of bronze sliding bushings
2 types of fabrics for cover production
3 types of fabrics for the production of the infant sling

Plus a whole range of other components: wheel set (2 x 12 inch, 1 x 20 inch), quick-release hubs, shock absorber, brake with disc, lever, cable and bovden, 10 types of bolts, washers and nuts, 9 types of small plastic parts, small upholstery material (zippers, Velcro, reflective tape, thread, etc.), etc.

Tubes, rods and yokes are needed:
1. cut into 22 different lengths, 2. bent, 3. drilled, 4. milled, or machined on a lathe, 5. welded into 9 parts of the frame, which we call (also in the drawings) : lower part with seat, back support, upper shorter part, upper longer part, swingarm, axle, pull bar, handle bar tube and handle, 6. clean some parts of the frame after welding with a reamer and taps, 7. re-polish the welded stainless steel handles with a grinder

Subsequently, we need to:
1. take the finished parts of the frame to the paint shop, 2. assemble the painted parts (screw them together), 3. cover the finished frame with upholstery, 4. install the shock absorber and brake, 5. fit the frame with wheels, 6. test the swingarm and brake adjustment, 7. test the functionality of the adapter and tow bar, 8. disassemble the trailer and pack it in a box, 9. send it to the owner

That’s it. Now you know a little bit more 🙂
