Batch Cropping using Actions

Record Action:
select all
transform selection to desired width OR height
crop
deselect all
image size (to desired final width OR height,  ...if required)
save
close

run action on other images using file>batch.

We need more information to help you with specific instructions. Otherwise, try @Stephen Marsh  suggestion to use Canvas Size.

Those image attachments are invalid.

You can record changing the canvas size into an action, only changing the width. 

This could be a single step, centre anchor point, cropping the same amount from both left and right sides.

Or, if both sides require different values, this could be two steps: setting the anchor point on the left, adjusting the value so that the right-hand side is cropped, and repeating vice versa for the other side.

Another option is to setup a "crop file" where you load a selection and use that for batch cropping in the action.

Please post meaningful screenshots, including the fully expanded Action in the Actions Panel, the Batch settings etc. 

Edit: What is the target width, what are the current pixel dimensions of the images? 

And please post them with the »Insert Photos«-button.
