Frequently Asked Questions

Q: What types of carts are compatible with these triangle stair climbing wheels?

A: These triangle cart wheels feature a universal plug-in design with a 7.5mm installation aperture, making them compatible with most standard shopping carts, hand-drawn trolleys, laundry carts, and small pushcarts. If your cart axle fits a 7.5mm opening, these wheels should install easily.

Q: Are these wheels foldable or collapsible?

A: No — these wheels are non-foldable by design. Their fixed, rigid construction is what gives them their exceptional stability and high load-bearing capacity of up to 35 kg per wheel, ensuring safe and reliable use on stairs and flat surfaces alike.

Q: How do the triangle wheels help when climbing stairs?

A: The triangular arrangement of the wheels creates multiple contact points as the cart meets each step. This distributes the cart's weight more evenly across the stair edge, allowing the cart to roll up or down stairs smoothly rather than getting stuck or tipping — making multi-level trips far more manageable.

Q: How many wheels come in one package?

A: Each package contains 1 triangle stair climbing wheel unit. If your cart requires a full set, please order the appropriate quantity.
