Kevlar, many layers for walls.

 

That is the way to go.

 

So maintenance, along with the chains,

can climb up and install the rolled up kevlar,

as it will require replacement after however

many usage.

 

May work better if kevlar is

'sweeping the floor' like the chains.

lesser chances of mines hitting the machine...

 

height and width (distance) from the machine itself

is required due to blast of the radius ---

let the chains and the kevlar walls deal with

the explosion.

 

then, heal/replace what is worn out

with maintenance.

 

if the 'disc' as i mentioned earlier ---

is big enough, and the rod/pole/drill

to the ground is long enough,

 

(the disc being middle or 70% of the pole)

if it has enough radius,

should be able to lift the machine up

and then rotate to a new direction.

 

feature may be useful in programming

point of view. easier setup in direction.
