Project to design and calculate the hydraulics for a deck crane

[Nero]

Hi, Iam having a really hard time with this university project.

The project is to design and calculate the hydraulics for a deck crane.
The crane boom must be lifted with one or more cylinders and you want a boom angle from 0 to 80 degrees.
Lifting capacity must be 10 ton on 20 m arm at a boom angle of
0 degrees (horizontal). Boom weight is 4 ton
Lifting speed on hook is 0.5 m / s and boom can be operated and lifted with full load from 0 to 80 degrees in 30 seconds.
The time for a complete crane rotation must be max. 1 minute

Can someone help please? how to start and what are the things i should take in consideration

Welcome to the PF.

Since this is your schoolwork project, you will need to do the bulk of the work.

What are the Relevant Equations for this type of mechanism/device? It sounds like you are supposed to use hydraulic cylinders for this project? Can you post some pictures of typical deck cranes in this size range and talk about how they have solved the various issues involved in their design? Thanks.

Like this one, for example?

Welcome, Nero
What is the scope of your work?
Is it limited to calculating and designing a rigid non-extensible boom, its pivot points and hydraulic cylinder?
Do you have a commercially available selection of hydraulic cylinders and pumps to choose?
What have you done so far?
