A two-ply ladder cart is an auxiliary operation tool for climbing to access goods. The two-ply ladder cart comprises a cart body, treadles (3) movably fixed on the cart body, an armrest (4) above a rear support rack of the cart body, and caster wheels (1), and is characterized in that the number of the caster wheels (1) is two, and the caster wheels are arranged on the outer side at the bottom of the rear support rack of the cart body (2). The caster wheels are not at the bottom, so that an operator is prevented from swaying when using the ladder cart. When the ladder cart is used, four standing supports are in direct contact with the ground, so that the cart body is more stable. The two-ply ladder cart has the advantages of safety, reliability, simple structure, convenience, quickness and the like.
