Modular Steel Ballast System for Flexibility

摘要

The CW34 is an eight-wheel roller with an operating range from 10 to 27 metric tons, designed for work on granular materials as well as all types of asphalt mix designs on all phases of compaction, Cat says. The CW34 delivers compaction with flexible ballast, oscillating front and rear wheels, front suspension, and optional air on the run. Rear ballast options include modular and non-modular steel, sand, and water. The modular steel ballast system can be added or removed, making it easy to adjust operating weights and match job site requirements. The oscillating front wheels deliver vertical and horizontal forces that reduce air voids, while the air-on-the-run option allows the operator to adjust wheel pressures in order to increase or decrease static loads.
