Cart Test Procedures <br />The tests outlined in this document primarily focus on measurement of the container’s <br />ability to withstand the rigors of regular usage in a waste collection system. Additional <br />consideration should be given to the testing described in ANSI Z245.30-1999. These <br />ANSI tests focus to a greater extend on ease of use and safety issues. <br />1.LOADED CART DROP TEST <br />The subject cart is loaded with 300 pounds of sand or other static ballast. The carts are <br />then lifted to a height of 12 feet and dropped onto a concrete surface . The test is <br />repeated five (5) times. Carts are then carefully inspected for evidence of any failure. <br />The Loaded Cart Drop Test simulates the stresses that carts must endure through years <br />of lift cycles, especially in fully-automated applications. This test provides a very good <br />indication of the overall strength and durability of the cart. <br />2. WHEEL DURABILITY <br />The test cart is fitted with the subject wheels. The cart is loaded with 336 pounds of <br />static ballast. The cart is then rolled off of a standard curb with a dead drop of at least 6 <br />inches, onto a solid surface. <br />The test is repeated a minimum of 520 times. Wheels are inspected for cracks, flat <br />spots or any deformation. <br />3.AXLE STRENGTH TEST <br />The subject axle is positioned for testing with support 1” from each end. Weights are <br />added to apply downward force against the center of the axle. Additional weight is <br />added until a permanent deflection in the axle is noted. <br />The amount of force it takes to bend an axle is a measure of how well it will hold up <br />when being rolled while fully loaded. <br />In conjunction with the wheel durability test, the axle strength testing also indicates how <br />well a cart will perform when dropped onto the wheels, being rolled up and down curbs <br />or stairs, or is rolled over rough surfaces.
