At the heart of grain elevators lies the crucial process of weighing trucks that bring in the precious grain. Effective communication during this operation is paramount to ensure a smooth workflow. Truck scale intercoms play a pivotal role in facilitating seamless communication between truck drivers and scale operators. However, like any system, there are challenges to overcome to achieve optimal performance. In this article, we will delve into the common issues faced with grain elevator intercoms and explore innovative solutions to address them.

Common Challenges with Grain Elevator Intercoms

Truck drivers encounter difficulties reaching intercom buttons from within their cabs, especially when their trucks are equipped with protruding mirrors. To overcome this challenge, advanced wired and wireless intercoms employ amplified speakers, producing ample volume for effective communication without requiring drivers to get too close. Additionally, incorporating optical sensors on the outside intercoms allows for automatic calls to scale operators, enabling convenient hands-free communication.

Noisy Engines

The loud engines of trucks pose a hurdle for scale operators in understanding drivers' communications. A successful truck scale intercom system necessitates two key technologies: Acoustic Echo Cancellation (AEC) and Active Noise Cancellation (ANC). AEC ensures full-duplex communication and effectively cancels feedback on both ends of the system. By further integrating ANC, engine noise is suppressed, resulting in clear and intelligible conversations. Investing in high-quality components and engineering is paramount to achieving both volume and clarity in communications.

Truck Height

Truck scales encounter a variety of vehicle sizes, prompting the question of optimal intercom positioning. If the intercom does not require manual button activation, it can be mounted at an intermediate height, accommodating trucks of varying sizes. However, when button activation is necessary, a dual-height, pad-mount pedestal pole with options for 72" and 42" installation allows the placement of two intercoms at different heights.


The installation of wired intercom systems may become impractical due to obstacles like concrete, railroad tracks, or other barriers. In such scenarios, opting for wireless truck scale intercom systems becomes essential. Nevertheless, wireless systems may also face obstacles from buildings or hills. Overcoming these challenges may involve raising antenna height or employing wireless IP bridge equipment to convert wired systems to wireless.

Truck Length

Dealing with trucks of varying lengths can present dilemmas in intercom placement. For trucks of similar lengths, positioning the intercom based on the desired stopping point on the scale is an ideal solution. Conversely, trucks of different lengths may require placing the intercom towards the front of the scale, as long as the scale maintains accurate measurements for smaller trucks. Utilizing signage can also assist in guiding truckers to the appropriate stopping positions.


Grain elevator intercoms are indispensable for streamlining communication between truck drivers and scale operators, ensuring an efficient workflow. Overcoming challenges related to driver arm length, engine noise, truck height, obstructions, and truck length is pivotal in establishing effective communication. Investing in high-quality systems equipped with advanced AEC and ANC technologies guarantees the necessary volume and clarity for seamless conversations.
