New Hand-Held Compaction Control System

A new hand-held compaction control system CompLogger is introduced by Dynapac as a soil compaction analyzer providing the customer with a real time image of compaction over the entire surface to be compacted.

This easy to use CompLogger can be used for production planning and throughout compaction. Further, the data can also be saved for future quality control and evaluation.

Based on Dynapac´s existing Compaction Meter and Compaction Analyzer, the new hand-held system is thought to be an industry first and features a rugged PDA and wireless data transfer technology.

The new hand-held facility is an easy to use, simplified version of the fully comprehensive Dynapac Compaction Analyzer system (DCA) which, nevertheless allows the operator to continuously read a direct feedback of the compaction results; enhancing the operators efficiency and compaction performance.

It is able to accommodate and evaluate a wide spectrum of parameters. These include rolling direction, rolling speed, vibration frequency and amplitude as well as the Compaction Meter Value (CMV) as measured by the roller,
Compaction results identifying possible problem areas are illuminated with user-friendly graphics.

Areas showing a poor compaction result are quickly identified allowing additional passes. If the compaction value does not improve, the operator is alerted and able to address the problem before the next layer is laid. In this way, for example, the operator is able to recognize and correct any problems whilst the machines are on-site. To return to the project and correct the compaction problems at a later date is both expensive and creates additional delays.

Weighing just 0,5 kg the robustly-built, compact hand-held CompLogger is easy to install as it is battery-powered and utilizes wireless technology. The system also features dust and waterproof hardware. Similarly it does not inhibit operations in anyway and can be instantly connected/disconnected with ease as required, including from roller to roller on multi unit applications.
