Measuring Lego Technic Crane Efficiency

[TechnicBrickPower]

Hi All,

For those that like measuring and calculating things...like me...here's a video I made on measuring the efficiency of a Lego Technic MOC crane.

Would appreciate any comments or feedback - it's a lot of work (but fun work of course) making a video so I do hope some people out there enjoy this kind of thing. Am always trying to improve my videos - am a newbie at it lol. If you have any video ideas around this theme let me know (unless you're making one yourself already).

Even better would be if you could subscribe to my channel - that will encourage me to make more videos! It's hard to get content out there.

Please share with your friends if you think they might enjoy it too.

Take care, and keep building... Rob

That's a really interesting video! The results surprised me too!

It would also be interesting to measure the efficiency of different gear combinations, for example 8T-40T vs 8T-24T + 12T-20T (both 1:5)

Interesting work! I wonder if this is directly the efficiency curve of the motor, or whether the gearing has a variable efficiency based on the amount of torque/weight involved (my guess is that at least the spool axle has increasing friction losses with more weight)

Thanks Sadap and vectormatic. Glad you both enjoyed this measurment. It's nice to receive some good feedback on my hobby videos. Yes the results are interesting and am looking doing some more tests with other gear combinations like you suggest. The heavier weights do increase the friction dramatically and I need to design the support around the axles better so they don't bend as much.

Am away on a 4 week holiday at the moment so won't be until next year!
