First published in bauma Preview - February 7, 2019

Dynapac is now offering special High Climb (HC) soil compactors. These are specially-adapted versions of the CA2500 and CA3500 models bearing HC logos and which meet the Stage IV and Tier 4 Final emissions requirements. A key feature of the High Climb models is that they are able to climb the same grade of slope, whether operating in forward or reverse. The High Climb application is suited to duties such as compaction in trenches and allows a machine necessity to reverse up the grade of a trench, where turning around is unfeasible due to the narrowness.

This higher gradeability in reverse as the machine is equipped with the firm’s latest Anti-spin versions of its NoSpin rear axles. To achieve this, the firm has used new, heavier components in the rear axle, drive, motor and transmission. The new configuration allows the drum to push the machine in reverse up a slope of 28°.

PD machines and D machines are fitted with pad shells achieve a perfect grip in soil. However, the smooth drum versions also offer sufficient grip to drive the machines in reverse. Special mechanical stops have been added on the drive side of the drum, preventing unwanted overload of the rubber elements. In order to assist the operator, the displays on HC machines indicate both tilt and gradeability.
