Hydraulic crane (T and J) #1: Crane boom

3263
11

This is part 1 in a 4 part series: Hydraulic crane (T and J)

A while ago I started another T and J building process. And from that what I think might be interesting I will make a blog entry.

According the plan the boom of the crane is equipped with spacers. But when the humidity change also the fitting will change. Therefore I made (wooden) springs. The boom is made out of ash. And ash is great for making a compression spring.

Thanks for watching.-

That is impressive , what type of crane are you building . I love cranes , I run a 25 ton Grove for years . I never ran a tower crane , but one day I want to make a scale model of one . Can’t wait to see your finished crane

Great technique Jan. It could also be used for and extendable lamp for example.

Very cool. What type of wood are you using? Being that the parts are very small or thin are you still using normal woodworking equipment?

Very cool. Yes ash is one of the more flexible hardwoods out there.
Enjoy watching our work.

This is interesting and I will be watching this as you go along .
I love how you made the boom tube assembly and the design may have applications elsewhere so I will put that in a special drawer for further reference .
