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.

Claims (12)

1. A method for storing and handling spacers having an eye at one end of the spacer, the spacers being used for spacing wire mesh cages employed in the manufacture of large concrete products, said method comprising:

providing a plurality of hollow tubes;

sliding a plurality of said spacers onto each tube with the tube extending through the eye of each spacer;

providing a moveable cart having a vertical support with a plurality of outwardly extending arms spaced apart vertically on the support;

sliding the tubes containing said spacers onto the arms; and

removing the spacers from the tubes as needed.

2. A method for storing and handling a plurality of spacers each having an eye at one end of the spacer that can become entangled with other spacers when they are stored or handled, the spacers being used for spacing wire mesh cages employed in the manufacture of large concrete products, said method comprising:

providing a plurality of elongated, substantially straight members smaller in thickness than the eye of said spacers;

sliding a plurality of said spacers onto each member with the member extending through the eye of each spacer; and

placing the members containing said spacers in a shipping container the width of which is slightly wider that the length of the member so that the spacer will remain on the members until removed from the container.

3. The method of claim 2 in which the members containing the spacers are placed in the shipping container in layers, each layer being separated by a barrier.

4. The method of claim 3 in which the members containing the spacers are removed from the shipping container; and the spacers are removed from the members as needed.
