New light compaction line from Doosan Portable Power to debut at World of Concrete

Doosan Portable Power will showcase a new light compaction line in exhibit W1119 at World of Concrete 2022. Four new light compaction machines will be on display: a forward plate compactor, a reversible plate compactor, a trench roller and an upright rammer. The trench roller is a new product addition to the Doosan Portable Power lineup, while the other three machines have significant product updates.

Each machine in the lineup is redesigned and powered by the latest Honda or Yanmar engines. Extra attention was paid to making service points easy for operators to access without tools while also adding guarding in vulnerable places to maximize durability.

New machine options increase ease-of-use and maintenance, including available transport wheels for all models, hour meters to track service intervals and water sprinklers.

The Doosan DTR3275 trench roller

The new Doosan DTR3275 trench roller enables more efficient, safer trench compaction. The roller is operated from a wireless remote that is solar-powered, so crews do not need to enter the trench or worry about charging a remote.

The Doosan DT3275 articulates left to right while also oscillating up and down. This wide range of movement increases roller ground contact to complete the job in fewer passes. The central articulation joint is maintenance-free for increased up-time.

Doosan DRX70 upright rammer

The Doosan DRX70 upright rammer has an optional air pre-filter system that lowers pressure on the air filter and extends air filter life to reduce the cost of machine ownership. To further extend up-time, all major service points can be accessed without tools.

The rammer's offset shoe design makes it easier for operators to place the shoe against walls, and is available in six different shoe widths. Operators can adjust the handle to three positions, matching the height of the operator, for a more comfortable, ergonomic operation
