Listed capacities range from 800 to 1,200 pounds. Use those figures when evaluating whether a cart/dolly is suitable for a particular boulder — check the specific product listing for the exact rated capacity of the model you plan to use.
The carts include convertible or pivot/adjustable handles that let you switch between hand-pulling and tow‑behind use; one model specifically notes a 180° adjustable handle to simplify steering and maneuvering heavy loads.
They use quick‑release dumping mechanisms (often front‑mounted) designed to let you dump heavy material with minimal effort.
The carts use 10‑inch all‑terrain tires; listings mention both large air‑filled 10" tires and 10‑inch no‑flat all‑terrain tires.
Bed volumes in the results range from about 4 cubic feet up to 7 cubic feet.
Descriptions highlight weather‑proofing such as UV‑protected polyethylene bodies and corrosion‑ or rust‑resistant steel frames to withstand sun and moisture exposure.
At least one listing specifies adult assembly is required and that tools are provided; another notes easy assembly for gardening and landscaping tasks. Verify included tools and instructions on the product page for the specific model you plan to buy.
