Due to the pronounced vertical components of motion in the single-toggle machine, it is obvious that a wiping action takes place during the closing strokes; either, the swing jaw must slip on the material, or the material must slip along the stationary jaw. It is inevitable that such action should result in accelerated wear of the jaw plates; consequently, the single-toggle crusher is not an economical machine for reducing highly abrasive, or very hard, tough rock. Moreover, the large motion at the receiving opening greatly accentuates shocks incidental to handling the latter class of material, and the full impact of these shocks must be absorbed by the bearings in the top of the swing jaw.
Metals are important raw materials for the industry and can be repeatedly returned to the recovered resource cycle with very little loss. The recycling of metals saves valuable raw materials and energy as opposed to the new processing of ores.

Caterpillar engineers have been testing two 795F AC prototypes, including the truck shown at MINExpo, at the Tucson Proving Grounds. The development program has provided input for the construction of a new 795F AC in Decatur, Illinois. The new truck recently shipped to a copper mine in North America where it will serve as the first field-follow 795F AC as it works at the mine. The 345-ton-capacity (313-tonne-capacity) 795F AC will enter a new size class for Caterpillar, and, as a result, the primary focus of the Caterpillar AC electric program has been on the 795F AC. The commercial launch date will be defined as the field-follow program progresses.
