A
pallet racking comprises at least one pair of spaced, parallel rails and first and second wheeled carts mounted in rolling relation with the pair of rails, the wheels of first and second carts respectively rolling on the same rolling surfaces. The front wheels of the second cart are positioned between the front and rear wheels of the first cart. As the result of this, the second cart can roll between a first, vertically overlying position relative to the first cart, and a second position where most of the second cart is spaced along the rails from the first cart.
In a
pallet racking which comprises at least one pair of spaced, parallel rails, having rolling rail surfaces, and first and second wheeled carts mounted in rolling relation with said pair of rails and defining a load-carrying area and front andrear wheels, said second cart being capable of rolling over said first cart to overlie said first cart, the improvement comprising, in combination:
said rails being each of I-shaped cross section, the wheels of said first and second carts respectively rolling on the same rail surfaces, the front wheels of said second cart being positioned between the front and rear wheels of the first cart,whereby said second cart can roll between a first vertically overlying position relative to said first cart and a second position where most of said second cart is spaced along said rails from said first cart;
The
pallet racking of claim 1 in which each of said pair of rails comprises a vertical web and a pair of generally horizontal flange portions having upper surfaces extending outwardly in opposed directions from said web, the wheels of said firstand second carts riding on the same one of said flange portions.
