What Is the Crosby | Straightpoint Radiolink Plus Load Cell?

How Does the Crosby | Straightpoint Radiolink Plus Load Cell Help with Your Lifting Applications?

Matt Florjancic

“An investment in knowledge pays the best interest.”

Benjamin Franklin was a man of many talents, but the writer, scientist, inventor, statesman, diplomat, printer, publisher, and political philosopher was ahead of his time. His words translate well to the lifting and rigging industry. Knowing the weight of your lifts could be the difference between going home safely or suffering catastrophic injury / death.

To know the weight of the load, you need a device built to measure the strain on the crane. The Crosby | Straightpoint Radiolink Plus Load Cell helps you know your load’s exact weight and eliminate the risks associated with guessing.

Eliminating hazards as often as possible when lifting loads could prevent catastrophic failure. Experiencing a catastrophic failure could not only result in damaging a load, but, more importantly, cause injury or death.

In this article, we’ll look at the following:

  • What is the Crosby | Straightpoint Radiolink Plus Load Cell?
  • How do you read the results from the Crosby | Straightpoint Radiolink Plus Load Cell?
  • What are the key specs of a Crosby | Straightpoint Radiolink Plus Load Cell?
  • What separates the Radiolink Plus from other Crosby | Straightpoint Load Cells?
  • What are the limitations of the Crosby | Straightpoint Radiolink Plus Load Cell?

What Is a Crosby | Straightpoint Load Cell?

Using a load cell or dynamometer is all about knowing how much you’re going to pick up.

The load cell is a device that indicates how much weight you have on your hook. Strain gauge technology measures the microscopic strain on the body of the load cell. Then, the results are converted into a pound, kilogram, kilonewton, or metric ton reading.


Crosby Straightpoint Radiolink Plus Load Cell with Handheld Display Device

The RadioLink Plus is Crosby | Straightpoint’s link-style load cell with shackles on the top and bottom of the device. It is their most commonly used load cell for monitoring loads. In their opinion, monitoring load weight should be done for every lift.

You put one shackle on the hook and attach the rigging to the bottom shackle. A wireless handheld device receives the information, which helps keep operators a safe distance away from the lift.

The wireless handheld device has a 1,000-meter range, which equates to more than 3,280’. Although Crosby | Straightpoint has never seen a need to be that far away from a lift, it means the Radio Frequency (RF) signal from The Radiolink Plus remains strong at varying distances from the load.

Sometimes, you will see load cells with an integral screen, which creates a couple of issues in some cases:

  • Puts the operator in close proximity to the lift
  • Is difficult to read from far away

Because of space limitations, the screen is typically an inch or less tall, and sometimes, not backlit. You’ve either got to be really close to the load and put yourself at more risk for serious injury/death, or utilize a lower-tech option like binoculars.

Binoculars still may not be enough, as it could be difficult to tell apart similar-looking numbers on the screen. Results obtained this way may not be able to answer if the crane/rigging gear being used to complete the task is suitable to perform safe lifts.

The Radiolink Plus load cell is strictly wireless. There is no screen/read-out built into the structure of the cell. Even if gouged or dinged, the Radiolink Plus remains functional because it features a completely polycarbonate front plate.

If your load cell’s screen is damaged, it can no longer be used without first going in for assessment / repair.

Crosby Straightpoint Radiolink Plus Load Cell Being Rigged to Load and Sending Signal to Handheld Device

The following specifications are among the most important when researching the Radiolink Plus load cell:

  • Range
  • Weight
  • Capacity
  • Battery type / life
  • Display type
  • Operating temperature
  • Accuracy
  • Frequency
  • Protection


The wireless radio frequency signal can reach up to 1,000 m or 3,280’.


Depending on which of the 14 models of the Radiolink Plus you select, it can weigh as little as 3.3 lbs. (1.5 kg), or as much as 425 lbs. (193 kg).


The smallest Radiolink Plus has a capacity of 2,200 lbs. (1,000 kg), and the largest model has a capacity of 1.1 million lbs. (500 metric tons).

Battery Type / Life

The Handheld Display requires 2 AA batteries, while the load cell needs 4 AA batteries.

Display Type

The Radiolink Plus comes with a 240×128 multi-line dot matrix display with a backlight.

Operating Temperature

The Radiolink Plus can operate between 14°F to 122°F (-10°C to +50°C).


Across all 14 models, the Radiolink Plus has an accuracy of +/- 0.1% full scale.


The Radiolink Plus has a 2.4 GHz frequency.


The Radiolink Plus is IP67 rated. It is dust tight and watertight against water immersion between 15 cm and 1 m for 30 minutes.

Crosby Straightpoint Radiolink Plus Load Cell and Bluelink Dynamometer

The biggest differences between the Radiolink Plus and another Crosby product, the BlueLink Dynamometer, are:

  • Range
  • Accuracy
  • Capacity


The wireless signal range of the Radiolink Plus is up to 1,000 m or 3,280’, which is 10 times the frequency strength of the BlueLink Dynamometer (100 m or 328’).


The Radiolink Plus has an accuracy of +/- 0.1% full scale, while the BlueLink has an accuracy of +/- 0.2% full scale.


Because there are 14 models of the Radiolink Plus, they can have a capacity of anywhere between 2,200 lbs. (1,000 kg), and the largest model of 1.1 million lbs. (500 metric tons). The BlueLink Dynamometer comes in one model, and its capacity is 14,300 lbs. (6.5 metric tons).

Crosby | Straightpoint’s load cells are designed to operate between 14°F (-10°C) and 122°F (50°C).

If you’re making a lift in sub-zero temperatures, it’s probably not a fit for Crosby | Straightpoint load cells.

Conversely, in hot forge foundries, customers will put a load cell on a crane that’s getting up to 150°F, and others have said, “It’ll flash a temperature of 250°F.” Crosby | Straightpoint doesn’t have an effective solution for something that hot.

Crosby | Straightpoint does make custom project load-monitoring solutions, so special applications can be reviewed for capabilities.

If you work in a hazardous environment where you’re using spark-resistant cranes and hoists and explosion-proof equipment, Crosby | Straightpoint has an ATEX (Atmosphere Explosible)-rated load cell that can be used. The specialized load cell must be marked by ATEX and has to be ATEX-approved.

***Remember to have conversations with your rigging specialists and reach out to manufacturers to understand what you’re getting into because the equipment/tools business is not a “one-size-fits-all, out-of-the-box” application. Do your research on what you’re about to rig BEFORE you rig it.
