tipper motor recommendation

[pedrcri]

hey guys,

need a little advice on what would be a good performing motor for a tipper trailer which can easily unload heavy sand weighing about 10lbs? I currently have a screw drive from Aliexpress which is hooked up to a small esc which is running a 100rpm motor. I feel it struggles to run till most of the dirt/sand is dumped. its a 30mm motor.

any advice helps with anyone who already has a build that works with similar setup.

it is for this trailer dumper.
