Bi-directional ratchet need help

We are using a winch in order to telescope this year, and the only realy problem with our setup is that when there is no powere given to the motor (once it is no longer stalling) the motor will backdrive. to eliminate that i thought i could use some kind of ratchet. So my real questions are:

Have other teams used ratcheting winches, how did they work ?

Did you only have it ratchet in one direction or did you do both ?
personally i would like to do both but i have no clue on how i can engage and disengage the pawl.

Is there anyother way to do it without ratchets?
worm gears are out of the question, because i cant really affor to reduce the motor anymore.

The only other setback is that we are not using pnumatics so they are basically out of the question.

Thankyou in advance
