Haver & Boecker has completely revamped its large bag weighers, resulting in a maintenance-free system that has a new drive technology for clean filling with high weight precision. Designated Elementra, its modular design offers a high degree of flexibility. The new Big Bag system is especially suited for loose, bulk materials of every type, especially for the construction, chemicals and foodstuffs industries, permitting large package units to be filled by a variety of dosing systems.

One feature of the revamped system is its modularity, permitting different dosing units to be utilised and integrated with existing production and packing lines. The machine can be expanded and equipped with different components, including options such as:

• Filling spouts that can be swivelled
• Different dosing units
• Inflatable sleeves
• Hooks: rigid, rotatable or replaceable, instead of a carrying arm
• Movable filling head or conveyor unit
• Vibration base
• Conveying system

In this way, smaller or newly established companies can acquire a Haver & Boecker machine and to set it up so that it may fulfil additional requirements later. Thus the revamped system covers everything, from the starter model to the high performance system for all applications.

The greatest technical innovation for improving safety and preventing machine stoppages is the double-belt drive, which meets explosion protection requirements. And because of its special plastic material, it is suited for use in the food industry and in dusty environments. Thus the belt-drive system replaces the maintenance-intensive chain drive.

There is also special emphasis on cleanliness and operator friendliness. For clean filling without product loss, the filling spout can be sealed with an inflatable sleeve and a counter-pressure ring – thus providing a completely sealed-off product path. Through the operator platform, the rotatable hooks, or other optional additions, the system can be expanded to eliminate hard physical labour.

The heart of the Elementra is the standard MEC 4.0 weigher electronics that control the weigher and networks for all individual modules for a weight-precise filling. To provide optimum, intuitive operation the system is equipped with a large touchscreen panel for displaying all functions and diagnostics with just a touch of the finger. The system can be equipped with the Haverquattro Monitoring System for constant online transmission of performance data.
