Design. Build. Test. " Monkey Claw" - new equipment attachment

What happens here

The team reviews the 3D CAD (Computer-Aided Design) model of the 'Monkey Claw' on dual computer monitors with DJ (the designer). The design features three lower tines, intended to provide a large surface area for handling loose concrete and allowing for shaking out dirt. The upper section incorporates two independently moving claws, designed to effectively grapple uneven loads. The discussion also covers the use of replaceable wear edges on the tines, made from AR400 abrasion-resistant steel, which can be sharpened with a grinder as they wear. The cylinders operating the claws are internally protected within the attachment's frame, eliminating the need for external guards.

Goal: Finalize the design specifications of the 'Monkey Claw'

out for you all right cool let's check it out you want to check her out yes i do so this is dj right yep this is dj dj how you doing man good how are you good so this is the monkey claw this is it could you blow that up a little bit bigger dj so we can see it so what we did too is we uh added them replaceable edges on it so the design has just let's go over this real quick for these guys the design has three tines on the bottom and what what we were hoping to achieve by doing that was we wanted to have a larger surface area so that when we got more loose concrete material we'd have something but also by having the more tines here if we wanted to shake any of that dirt out we could do it and then we decided to go with two claws on the top and the reason we wanted to do that is as we had more loose material we wanted to be able to have something that could come down over the top and just grab on to them now do these each float separate so that if we have more material on one side oh perfect yeah so they they're so if you get a load that's uneven mm-hmm you'll be able to grab both sides of it perfect now what were you saying about the wear edges derek well the only thing that we're worried about is this it almost gets utilized like a fork and we brought these two pieces up and we're meeting and putting a weld one of the worries is is that's going to wear over time so we do feel if we put this in production that they should be a solid steel chunk that's milled down kind of like a fork yeah that way as it wears you can just keep it sharpening with a grinder but i think the first one for the prototype we're going to do it this way because it's easy and fast less machining but long term i think it's a part that we would have to be machining out and i see you've got replaceable teeth on the sides yeah we do that we started doing that on the rotating grapples and it's really nice when you have an investment to try to protect that investment as well and everybody has a different idea they don't maybe don't want teeth that's where we come out with a flat edge so we have options of giving people something different if they need it and then replaceable teeth on the top too right on the end there yes we're going to build them out of a ar 400 so it's an abrasion resistant material okay are the grapples actually activated by one cylinder two cylinders probably well actually blo what we did is we we we got rid of the guards all together and we're just uh we have a drain…
