Cat 777D Mining Truck

Thanks everyone-the main topic seems to be weight capacity so I decided to check it out. The dump box in this video contains 6-1/2 lbs. of dry dirt. It struggles just a bit at lift-off but handled it just fine-

A normal load seems to be about 5-1/2 lbs. but I can heap it full and carry the 6-1/2 lb. load. The hinges just have 4-40 screws thru them now and are binding just a little. I think when I get pins installed in all the hinge points it will work better. I will know more later. Also everything is dry. I don't want to grease anything until it's painted.
