Robust and practical

The weighing platform is galvanized and has a carrying capacity of 15 t per axle. The scale is waterproof and 4 weighing cells with a 10 t nominal load each ensure it`s overloadproof as well.

Automatic weighing while in motion

The AGRETO drive-over-scale weighs the axle load of several vehicles that move over the platform. Axle loads are automatically added to calculate total weight. You don`t have to stand still or get out of your vehicle, and you don`t need extra personnel like you do with a weighbridge. PC software automatically logs all weighing data.

Reliable axle recognition

The AGRETO drive-over-scale`s light barrier system identifies tyre size, wheelbase, driving direction and driving speed. This enables exact and error-free weighing of large tractor rear tyres, as well as all axle combinations (tandem, tridem axles).

Control with PC software or weighing terminal

Optionally, the AGRETO over-ride scale can be operated with the new AGRETO weighing terminal or with a PC and the PC software. Please select as accessory either the terminal or the software control.

Installation requirements:
When choosing a location for your scale, make sure that the area for approaching and exiting the scale is as even as possible, for the entire length of the vehicles that need to be weighed (30 to 32 m in total for semi-trailer trucks). Ideally this roadway is level in all directions. A slight slope to the side or upwards in the driving direction is acceptable, when this slope is exactly the same everywhere on approach, scale and exit. For weighing multiple axles we advise the construction of a concrete slab at least 3 m before and after the weighing platform. The approach and exit are essential parts of the scale and must be constructed with care. In practice, proper installation and use will guarantee only minimal deviations from a calibrated weighbridge.
