Steel Wear Strips in Concrete

How about embedding some wide-flange beams with the top surface flush with the bin floor?

It all depends on the actual size and configuration of the concrete bin floor. you have several options that you can utilize:

Continuous steel plate anchored to the slab with Nelson shear studs or concrete anchors.

Parallel steel channels with shear studs or anchors welded to the inside face of the web, with the backside of the channel flush with the concrete surface (flanges, with tips pointed downwards, would be embedded into the concrete).

Install an industrial floor topping over the existing concrete floor, such as "Trap Rock". There are also "ferro" based concrete toppings that can be applied to the roughened surface of an existing or new concrete floor slab. These are extremely durable and highly resistant to equipment scraping blades.

Is this an existing concrete bin slab or a proposed one? Also, what material(s) are you scraping-up with the front end loader? Abrasive in nature, such as sand or rock salt, etc.?

Those are just a few suggestions that I can offer to you.....
