ESCO’s new Ultralok Tooth System eliminates a separate pin from the tooth/adapter interface. Each tooth/point has an integral hammerless locking mechanism to simplify installation and replacement. The Ultralok retainer is integrated into the tooth, so there is no separate pin to manage during installation and removal. Ultralok will be offered in seven construction sizes – the first two introduced at Conexpo-Con/Agg 2008. The tooth-and-adapter line will supply 6- to 75-metric-ton excavators and 3- to 12-cubic-yard wheel loaders. Key to the Ultralok system is that the adapter carries the load, and the pin simply retains the tooth on the adapter during most of the duty cycle.
Liebherr has developed a new range of Z-System ground-engaging tools to complement its mining-backhoe and face-shovel bucket design.
LEA’s staggered Multi-Ripper teeth function like trencher teeth, applying the excavator’s full breakout force on each tooth tip sequentially.
