How Much Does an Arrow Board Weigh?

The weight of arrow boards may vary depending on their size, design, and structural materials.

Typically, the weight of an arrow board trailer, including the board itself and the trailer frame, can range from 500 to 1500 pounds (227 to 680 kilograms) depending on its size and materials.

Vehicle-mounted arrow boards are lighter because they are designed to be installed on vehicles such as trucks or vans. Usually, the weight can range from 50 to 200 pounds (23 to 91 kilograms).

What Do Different Numbers of Lights Mean?

Small arrow boards suitable for less complex traffic situations, typically have 8 or 12 lights.

Large arrow boards come with more lights (e.g. 15 or 25 lights), some even double-sided, with 50 lights. Arrow boards with more lights have greater visibility and brightness, making them suitable for use in busy areas or low-visibility environments, such as on highways or at night.

What Does a Flashing Arrow Board Mean?

An arrow board usually indicates temporary changes in traffic or roads, and it can change the flashing mode and pattern of LED lights to adapt to different traffic situations. For example, if the arrow points to the right, the driver should move to the right lane or follow the indicated detour route. Similarly, if the arrow points to the left, the driver should move to the left lane or follow the designated alternate route.

Here are some flashing patterns on the arrow board:

Solar Panels on Arrow Board

Solar panels are crucial in providing sustainable and reliable power to arrow boards. Several solar panels are usually installed at the top of arrow boards to capture sunlight and convert it into electricity through photovoltaic cells. Then store it in batteries for future use.

The solar power allows the arrow board to operate independently of traditional power sources, and minimize environmental impact. It enables the arrow board to be deployed in different locations for temporary or remote traffic control.

Batteries of Arrow Boards

Arrow boards use rechargeable batteries, which are typically sealed lead-acid (SLA) or lithium-ion batteries.

Li-ion batteries have a higher energy density compared to other rechargeable batteries, so they can store more energy in a smaller and lighter package. But Li-ion batteries can be prone to overheating, fire, and explosion if they are damaged or improperly handled.

OPTRAFFIC arrow boards utilize gel batteries, which are a type of special lead-acid battery. The special feature is that the electrolyte is added with silica gel to form a gel state. The electrolyte in gel state has better anti-vibration ability and anti-leakage performance than the traditional liquid electrolyte. The internal structure of gel battery has been improved to make the pressure inside more balanced and reduce the risk of leakage and corrosion. In addition, gel batteries release oxygen during the charging process to recombine with water, ensuring the internal liquid level is relatively stable.

What Is an Arrow Board Controller?

Arrow board controller is a handheld device with a built-in management system used for operating and controlling arrow boards.

OPTRAFFIC handheld controller comes with a built-in WEB system, which is an integrated operating system that allows users to remotely operate and manage equipment through 4G network connections and integrates various functions, including setting flashing patterns, GPS positioning, data recording, equipment tracking, and monitoring. Repeated comparisons have proven that OPTRAFFIC handheld controllers are more convenient, user-friendly, and have faster signal transmission speeds than those on the market.
