Crane (Winter 2017)

Tuesday Crane - Week 8!

Today our goal was to be able to test the Crane out by the end of the day. To do that we needed to finish our swiveling plan, insert a pulley system between the arm and the hook, and because those things were so small and complex, we decided to make a car to pull our container to it's final destination!

Tuesday Crane - Week 7

After a week off, the Tinkerers came back ready for action. We started with an opening circle to identify the final steps needed to complete our crane project. We put our heads together and set-up our priorities.

Chloe started by attaching rope to the crane arm. 

We clamped the arm on top of the tower for a trial run. The rope successfully pulled up a bucket with a bowling ball inside. By doing this we identified that we needed to attach handles onto the opposite end of the arm to make the lifting motion easier.

So the kids set forth to design and build a handle. To do this they drilled a 1/2" hole to fit a steel rod. Then they attached 2x3 blocks along the handle to keep it sturdy.

The other half of the group worked on attaching a spool holder for the rope and creating a deck on top of the tower that would securely hold the swiveling crane arm.

Strengthening the Crane Tower

The tinkerers worked together today to make the crane tower stronger and safer. We checked for areas where screws may have been too short or the wrong size, we also looked for gaps in our construction, and checked the overall stability of the structure.

Leo presented an idea for a swivel top so that the crane arm could move from side to side. His plan consisted of attaching wheels onto the crane arm and adding handles onto the end of the arm to control its movement. At the end of our session everyone made drawings to share how we collaborated with each other.

Tuesday After School - Shipping Crane Week 3

Crane (Winter 2017)Lindsay JonesComment

To start week 3 of our project we looked at some images of cranes from the Port of Oakland  to gain an understanding of how they work and we discussed how we could engineer our design to be sturdy enough to pick up and move a 5 gallon bucket of water. Dividing into two teams (Crane and Container), Tinkerers started by reflecting on the steps completed last week and making sketches for todays ideas.

Today we began working on ideas to move a large container of water from one place to another. The idea originated from the concept of ships and containers at the port and possibly inspired by the large amounts of rain.

We spit into two groups. One worked on the carrier for the container and the other worked on the mechanisms to lift and move the container onto the carrier. Scarlett, Chloe, Ayush, and Louis each took turns measuring and cutting pieces of wood for the container
