| Hydraulic drive trencher  The improvements made as a result of the experience of the 300P series 1 to 3 have made it possible for the UNAC research department to design and produce the UNAC series 4 300P, equipped with a new generation 300hp Caterpillar diesel engine. The UNAC 300P carrier is versatile. Changing from one tool to another - saw, chain orvibrating ploughshare - can be done in an average time of one hour. This makes it possible for the same carrier to be available for all types of worksite. Thanks to the tilt corrector and hydraulic offset, the tool remains permanently vertical.The 300P also exists in a 500hp version. On the same basis as the 300P carrier, UNAC has developed the 300C carrier, on caterpillar tracks. It has been studied for work in all conditions, and is equipped with a chain and vibrating ploughshare. write your comments about the article :: © 2010 Construction News :: home page |
