Smart support for machine operators

Successful further development

Bad Laasphe: Weber MT, the specialist in hand-controlled compaction technology, is now beginning the market launch of the product innovations presented at the last BAUMA. One of these innovations is the "Weber Smart Assist" (WSA). The new system digitally supports the machine operator in the operation and maintenance of the machines.

The operation of hand-held soil compactors does not necessarily pose major problems for the experienced construction worker. However, the shortage of skilled workers on construction sites and the increasing rental of machines lead to new challenges. Users are therefore grateful for support in operation and maintenance.

This is where the new Weber Smart Assist comes into play. A product that combines familiar and new technologies. The innovation consists of the already proven compaction control COMPATROL and the MDM motor monitoring, now complemented by the user support WSA.

Motor monitoring

With the MDM engine monitoring system, which has been tried and tested for many years, the engine is always switched off then if engine damage is to be expected when driving on. Understandable, language-independent symbols on an easy-to-read display warn the operator, for example, of excessive engine temperature, lack of oil or low battery voltage. Ok the degree of contamination of the air filter is displayed, alerting the operator that the filter element should be cleaned or replaced in a timely manner.

User support

Simple symbols on the display now support the user in solving the problem signaled by the engine monitoring as well as in performing regular maintenance. Step by step it explains how to change the air filter element or where to refill engine oil. These are just two examples for which Weber Smart Assist provides support. Many users are familiar with such support from copiers that indicate how to fix a paper jam.

WSA offers even more. The compact display provides up-to-date information on engine speed, battery voltage and remaining available operating time until the next service. In addition, error messages that have occurred can be read out.

Compaction Control

Also part of the Weber Smart Assist is the compaction control COMPATROL, which appears in a new design. This indicates to the user the compaction progress in an easy-to-read and easy-to-understand bar graph. Weak spots in the soil can be recognized and remedied in time. Because unnecessary compaction is prevented, up to 25% time and costs can be saved.

The Weber Smart Assist is available as a new version with the designation WSA for the CR 6, CR 7, CR 8 and CR 9 reversible soil compactors. The machines weigh between 400 and 700 kg and have centrifugal forces between 55 and 100 kN. The development of the WSA was made possible by the use of Hatz diesel engines of the E1 series. The engines have electronic engine control, which automatically adjusts the correct speed.

Also new is the operation of the machines. After starting, the vibration is switched on by pressing a button. A throttle pedal or lever is sought here in vain. Two engine speeds can be selected that are matched to the centrifugal clutch. The engine controls the rest completely independently. WSA also takes ecological aspects into account. As soon as the machine runs without function for more than 3 minutes, the motor automatically switches to standby mode. This prevents unnecessary emissions.

On request, the CR 6 WSA and CR 7 WSA soil compactors can also be equipped with a diesel particulate filter - another new development from the Hatz engine plant. This enables operation in trenches or enclosed areas.
