This is a guide how you can use the different connection methods in RoR.
ties: these are beams that grab a node and pull them tight

hooks: nodes that interlock with other nodes or ropables
The documentation about ropables can be found here
The documentation about ties can be found here
Ties (as commands) can only work over an RPM of 800 and might request more power from the engine when being used.
So basically define a tie on the transport truck and a ropable on the load you want to tighten.

Hooks lock against nodes in a search area of 40 centimeters.
