In certain examples, a cart is for lifting a load and the cart has a base frame, a lifting frame pivotally coupled to the base frame with a link arm, a handle pivotally coupled to the base frame at a first pivot axis, and a brace. The brace has a first end pivotally coupled to the handle at a second pivot axis that is spaced apart from the first pivot axis along the handle and an opposite second end pivotally coupled to the lifting frame at a third pivot axis that is between the link arm and the first pivot axis along the lifting frame to thereby achieve a mechanical advantage for pivoting the lifting frame relative to the base frame as the handle is pivoted about the first pivot axis.
