Tangle free spacer cart

Abstract

A method and cart for handling spacers used for spacing the wire mesh reinforcing cages used in the production of concrete pipe. The spacers are placed and shipped on hollow tubes laid in layers in a shipping container. The spacers are shipped to the user stored on these hollow tubes together with a mobile cart that has a vertical support containing a plurality of outwardly extending arms. When ready to be installed at the concrete pipe production site, a tube containing the spacers is removed from the shipping container and slipped over each arm. The cart can then easily be moved around the production location where the spacers for readily available for use in making the concrete product.

Description

[0001]This application claims priority under 35 USC 119 to Provisional Patent Application Ser. No. 61 / 241,245 filed on Sep. 10, 2009, the contents of which are hereby incorporated by reference.BACKGROUND OF THE INVENTION[0002]In producing large concrete products such as box sections, round pipes, culverts or manholes, reinforcement wire mesh cages are required to provide the necessary strength to the finished product. When these cages are placed in the forms, they must be spaced from each other and also spaced from the surfaces of the form used to produce the particular concrete product.[0003]Commonly known spacers used for double cage reinforcement wire mesh cages for rectangular concrete products, such as box sections, have an eye at each end of a straight section. The eyes serve to space each of the cages from the surfaces of the product form. The straight piece between the eyes determines the spacing between the two reinforcement cages. For use with the double cage wire mesh cag...
