Bucket works one tooth at a time

Leading Edge Attachments, Inc., introduces the patent-pending STAG Bucket, a high penetration bucket utilizing “staggered tooth” technology. It is designed for excavators, allowing the operator to easily dig compacted soils, coral, shale, caliche, stratified materials, shot rock or frozen ground with higher concentrated breakout force. The new bucket is priced below the company’s Multi-Ripper Bucket. The STAG bucket design allows the operator to focus the excavator’s full breakout force on one tooth at a time because the front leading edge is angled. Creating flat trench bottoms is easy with this new bucket also because the teeth are on the same plane, similar to a conventional bucket.

The volumetric mixer carries the materials necessary for concrete production in separate bins and they are measured out at the job site where the concrete is produced in the machine’s exclusive pump master mix auger. Mix designs can also be changed per specifications with a simple and quick resetting of the aggregate bin gates.

N.M. OKs gravity retaining walls

New Mexico’s Department of Transportation has approved the use of Redi-Rock gravity retaining walls in DOT projects. The retaining walls allow engineers to design walls up to 24 feet high without geogrid or reinforcement due to the massive weight of each block. The DOT’s approval allows the walls that look like natural stone to be built up to 12-foot tall in DOT applications. The structural walls consist of individual one-ton blocks that interlock to create structural walls that require no mortar or pins.
