NSA-14〜50
Features
Shallow type improves workability
NSA type is top class shallowness compared to equivalent models of other companies. This reduces the risk of water gushing or coming into contact with bedrock, resulting in a 15% reduction in excavation volume. In addition, the simple structure of the contact aeration makes it easy to maintain.
