The locking system of ProMet III is common to the entire range of lip protectors, which include plate lips, cast lips and rope shovels.

Composed of a block, a plate and a bolt, the new locking assembly brings the following benefits to the system:

• Greater reliability against loss or fall in the most demanding uses, thanks to the replacement of the pin and retainer with a bolt and a plate that offer better performance.

• Reduction of replacement time, by minimizing the effects caused by compaction to the bolt, facilitating cleaning and subsequent handling.

• Increased safety because the bolt is handled from the top, improving its usability.

• Improved management by having unified all three components in a single part number.

ProMet III locking assembly for Cast Lips and Rope Shovels is compatible with previous weld-on bases. Below, we show the compatibility table between ProMet II and III for Plate Lips:
