Streamline traffic flow and enhance driver safety.
WEM Automation understands that operators should run the plant while drivers remain in their vehicles, minimizing printer issues for efficient operation and a safe yard.
Our remote printing capabilities significantly improve operational speed and safety by keeping drivers in their trucks. Additional features like signatures and cameras reduce the need for driver-plant interaction..
The laser printer is popular for its availability of replacements and standard paper options. These rear discharge printers drop tickets into a protected tray for easy driver access.
They’re preprinted standard-size stock for multiple copies, which can be color-coded for easy identification.
Our custom remote printer enclosure houses either a thermal or laser printer. Installed at load height, it allows drivers to pick up scale tickets without leaving their vehicles. The enclosure is made of industrial steel and includes a heater and cooling fan system.

Radio-frequency identification (RFID) is the latest technology used in the asphalt industry.
RFID tags store electronically accessible information and do not require line of sight for reading, allowing them to be embedded in trucks.
Each tag contains unique information, including Truck Identification Number(s), Company Name, and License Plate Number.
RFID readers at the plant collect information as trucks pass, using it to automate various operations, such as opening access gates, issuing tickets, activating display boards and traffic lights, and managing receiving and loadouts.
The aim is to achieve automation in the receiving and loadout process.
