GRAM PR is a mobile axle scale designed to quickly determine vehicle weights by weighing axle by axle. Its flat aluminium platforms can be used directly on the ground or installed flush into the floor, enabling flexible use as a mobile or semi-permanent weighing station.

Thanks to its 60 mm low-profile design, vehicles can drive on and off the platform without ramps in most situations. Integrated carrying handles allow the platforms to be transported and positioned easily, while the robust construction supports axle loads of up to 20 tonnes.

GRAM PR is ideal for applications where vehicle weight control, overload prevention, or mobile weighing is required without the complexity of a full weighbridge installation.

PW-Link Software

PW-Link is GRAM’s software for real-time weighing data capture and reporting. It connects your scale to a PC via RS-232 or USB and records each weighing automatically — including date, time, weight, unit, and weighing number. The result is a live, structured table where weights are captured instantly, eliminating manual entry and reducing human error.

From weighing to reporting, everything stays simple. Users just select a cell and continue weighing while data is registered automatically. Weighing records can be exported to spreadsheet or PDF formats, branded with your company logo, and saved directly to a defined local folder — making documentation, traceability, and reporting fast and reliable wherever accurate weighing data matters.

Connectivity & Data Output

GRAM PR offers flexible PC connectivity via USB, Direct K USB and RS-232C, allowing reliable data transfer for documentation and system integration. Standard USB and RS-232 connections support background data transmission to EX-Link software, a free Excel template, or custom IT systems using defined communication protocols.

For simple plug-and-play data entry, the Direct K USB cable sends the weight value directly as a keyboard input to any open application. For advanced reporting and traceability, PW-Link PC software enables structured weighing reports with date, time and weighing number, exportable as CSV or PDF files.
