GRAM Speed connects seamlessly with GRAM’s digital indicators — K3X, K3iX, K3iX-P, as well as the wireless options K3W and K3iW — and the Z8 and Z8i weighing terminals, via cable or optional Wi-Fi.
All compatible models support 3-colour checkweighing, multi-tare management, totalisation, and ticket printing, powered by the platform’s fully integrated Xtrem® digital core, which securely stores all calibration and configuration data within the system.

Through its K3 indicator compatibility, GRAM Speed integrates with the PR4 compact thermal printer and the Q2 label/ticket printer, ensuring clear, reliable documentation for vehicle entries, exits and operational control.
The Q1 Bluetooth label printer offers wireless label output and full Xtrem App integration when using the Premium option.

GRAM Speed provides advanced connectivity with RS-232C as standard and optional Wi-Fi, Ethernet and RS-485, enabling direct communication with indicators, PCs, tablets and Android smartphones. Its integrated Xtrem® digital module ensures secure communication, supports mixed wired and wireless layouts and allows the platform to operate fully autonomously. Through Wi-Fi or Ethernet routers, the scale can be integrated into a centralised multi-platform network, with Web Server access for browser-based data capture via Chrome, Edge or Safari. GRAM Speed works seamlessly with PC Xtrem for legal-for-trade PC-based indication, EX Link for data capture, PW Link for real-time display and CSV export, and the Xtrem App for Android, which offers multi-terminal workflows, barcode scanning and advanced traceability when the Premium option is activated.

GRAM Speed integrates with GRAM’s installation ecosystem, including painted or stainless-steel bases with 900 mm columns, stainless U-shaped wall brackets and ABS swivel supports, ensuring ergonomic and robust indicator placement. The platform supports an extensive set of connectivity options such as ZLink® cables (4 m standard, 8 m and 15 m optional), RS-232 cables for printers, RD3 or PC, USB outputs, Direct K USB, Wi-Fi boards, Ethernet and RS-485 modules, as well as digital expansion elements like the 3-relay board or RTC board. Additional platform accessories — including the RM-25 access ramp for smooth vehicle entry and the MP pit-frame kits for flush, ground-level installation — further extend the system’s safety, flexibility and operational efficiency in demanding industrial environments.

The platform supports the RD3 repeater display, enabling clear, high-visibility remote weight indication in control cabins or elevated viewing areas.
It is also compatible with the three-level LED traffic light, providing immediate colour-coded signals for vehicle positioning, checkweighing and operational safety.

GRAM Speed is supplied with CE-M verification for legal-for-trade vehicle weighing .
Optional ISOCAL certificates (up to 10,000 kg) provide individualised calibration data to align with ISO-based quality systems.
