Capacities vary by model. Examples given include 110 lb, 330 lb, 550 lb (hand truck mode), 600 lb (4-wheel mode), 700 lb, 770 lb (platform mode), 800 lb, and 1000 lb. One model also notes a fold-out nose extension that supports an additional 100 lb.
Folded size varies by model. Examples include units that fold to about 12.6 x 9.3 inches and others that collapse to roughly 25 x 18 x 4.5 inches. Many descriptions simply note a slim folded profile suitable for trunks or closets, so check the spec for exact folded dimensions.
Wheel types vary by model. Examples include small smooth 3-inch wheels; 8-inch puncture-proof/never-flat main tires paired with 3-inch 360° swivel casters; 10-inch pneumatic wheels with 5-inch swivel casters; and solid rubber wheels with swivel casters. Check each listing for exact wheel material and size.
Common materials include metal frames, alloy steel with reinforced plastic bases, reinforced spray-coated metal, and high-strength aluminum alloy (noted as rust-resistant in some listings). Review the product page for exact frame and base materials.
Included accessories vary but examples list elastic/bungee ropes, a plastic hook, a user manual, and on some models a foldable plastic basket and adjustable elastic straps for securing cargo. Verify the product description for the exact accessory list.
Some models list higher capacities in platform/4-wheel mode than in upright hand truck mode. For example, one model shows 550 lb in hand truck mode versus 770 lb in platform mode; another notes up to 600 lb in 4-wheel mode alongside other capacity figures. Check each listing for its mode-specific ratings.
