Also known as back savers, these Spring Lift Platforms make all kinds of material handling easier and less strenuous on your back because they eliminate excess bending! When loading materials into the cart the platform automatically lowers with the weight. When the materials are removed the platform automatically raises, bringing your materials up to the top of the cart. Spring Lift Platforms are available for just about all Starcarts. Spring Lift Platforms are easy to install; simply hook over the lip of the cart.
