First thing that comes to mind is lack of leverage.

Start a thread in the "All other parts" section, include pics of the whole setup & we'll go from there

Welcome to the forum. Below, is a picture of a mechanical over hydraulic cable adaptation I made. In this application, it was run off a foot pedal. The principal is the same, leverage. I fabbed the red cam from 5/16" steel plate, to replace the factory handle. Here's how it applies to you-

The turnbuckle in the picture is what the cable attaches to. The red bolt is what the cam pivots on. For an easier pull and a longer handle stroke, you would move that cable attachment point further away from the pivot. For a shorter handle pull that would require more force, you would move the cable attachment point closer toward the pivot. Leverage.

Post some pics of your setup, and we can get more specific to your application.
