5.0 Applications

The Load Ranger wheel weigh pads can be arranged to serve multiple applications. The adjustment from one scenario to another is made quickly and easily with the wireless and portability features of the Load Ranger system. This section highlights several of the arrangements available.

5.1 Wireless Setup

A wireless system allows for weighing with up to 16 connected wheel weigh pads per Ai-1 indicator. The wireless system is connected by following Section 2.0 through Section 3.0.

Typically wireless setup is configured for 2, 3, 4, 5 or 6 pads.

Wireless setup with an Ai-1 indicator is not limited to 2 to 6 platforms. The following illustrations show only the most common applications.

Two Platform Applications

Two platform applications include weighing axles of the vehicle individually or trailers with only one axle.

Figure 12. Two Platform Application

An illustration showing two wheel weigh pads positioned under the wheels of a single axle vehicle or trailer.

Three Platform Applications

Three platform applications include weighing small planes, three-wheeled vehicles or trailers with a support pin.

The size and capacity of the third platform can differ from those of the other platforms.

Figure 13. Three Platform Application

An illustration showing three wheel weigh pads positioned for a three-wheeled vehicle or a trailer with a support pin.

Four Platform Applications

Four platform applications include weighing two-axle vehicles, trailers, containers or other items with four support points.

Figure 14. Four Platform Application

An illustration showing four wheel weigh pads positioned for a two-axle vehicle or trailer, with two pads under each axle.

Five Platform Applications

Five platform applications include weighing two-axle trailers with a support pin. A sixth platform can be used when weighing both directions.

The size and capacity of the fifth platform can differ from those of the other platforms.

Optional sixth platform.

Figure 15. Five Platform Application

An illustration showing five wheel weigh pads positioned for a two-axle trailer, with two pads under the front axle and three under the rear axle (or vice-versa). It mentions an optional sixth platform for weighing in both directions and notes that the fifth platform's capacity can differ.

Six Platform Applications

Six platform applications include weighing three-axle vehicles or structures with six support points.

Figure 16. Six Platform Application

An illustration showing six wheel weigh pads positioned for a three-axle vehicle or structure, with two pads under each axle.

5.2 Charging Platforms

The power connection port is located on the underside of the wheel weigh pad.

For large weigh pads, the port is located on the black junction box at the wheel side (see Figure 17).

For small weigh pads, the port is located on the junction box at the handle-end of the platform and is the port closest to the handle (see Figure 18).
