One of the most crucial components of every rail operation is rail weighing. It is an element that aids in expenditure control and compliance in nearly every aspect of train transport — from tracking product shipping and deliveries to avoiding overloading penalties. Therefore, the dependability and accuracy of the methods and technologies utilized throughout the weighing process are critical to obtaining reliable results. And one way to achieve this is through railroad scales.
This article will walk you through everything you need to know about railroad scales, including their importance, procedure, and various types.
What Is a Railroad Scale?
A railroad scale is a weighing technology that uses strain gage systems. It is also used to ensure that the railroad car is not overloaded, which could damage the rail tracks and pose a security risk to the public. In addition, it prevents undocumented cargo and minimizes theft before and after transit.
Several sectors have recently recognized the significance of a railroad scale and have expanded its application for various purposes. For example, the construction and agricultural industries have benefited from rail-scale technology through shipments of industrial parts and food crops recycling.
Importance of Using Railroad Scales
Railroad scales are considered the ultimate technology for accuracy, resulting in cost-effective weighing for transportation and shipping. Here are some of the reasons why these scales are used in a wide range of industries:
To invoice customers for the exact amount of products and goods transported, transaction purposes, and verifying that customers are not overcharged or undercharged.
- To prevent overloading occurrences that could impact infrastructure and avoid eccentric loading that could cause delays and cancellations.
- To ensure that potentially damaging shipment leaks are spotted upon entry at the transfer station to avoid hazardous situations.
- To facilitate chemical components because most existing systems do not possess cavities or structures that lock up air heavier than explosive gasses.
- To align material flow specifications and manage loads during automated bulk loading to gain maximum capacity without overloading.
- To calculate the weight to collect the freight revenue from shippers.
How Railroad Scales Work
The scales are installed on the train tracks. First, the total weight of the cargo within the railroad car is calculated by measuring the vehicle’s mass and then applying the tare weight or the weight of an empty car. Then, you can compare it to other data obtained to ensure that the cargo and everything else is in order.
Most Common Types of Railroad Scale Products
The following are different types of rail scales, with each requiring varying site preparation, scale foundation, and track work to ensure a successful installation:
Pit Design Scale
Railcar scales in pit design are constructed into a trench so that the plate or load cell is at floor level. They operate very similarly to a standard human weighing scale. They also have more complicated mechanisms because railcars must pass over the scale to have their weights measured.
Railboss® Railroad Track Scale
The Railboss® Rail Scale from Rice Lake Weighing Systems is a low-cost and simple-to-install piece of equipment for weighing stationary rail cars. It is operated by Rice Lake’s 920i and Railboss software and comes in eight-section full-draft or four-section double-draft configurations.
