Smart Hook for Telehandlers Uses Straightpoint Load Cell

Load cell hook up

As described previously, the force needs to be applied to each load cell without any side forces or moments. If you have a three-wire strain guage then you will need a high accuracy resistor divider to provide the other arm of the bridge. It is a safe and simple solution.

They have load charts for each position but in most cases the end user does not know the weight of each load they are lifting, which should be confirmed before the operator extends out the boom. Operators typically read data via a device in the cab. Read up about instrumentation amplifiers for more insights. Under the ends of each of the support bars are where the load cells are installed. Four legs act as storage stands to keep the load cell off the ground.

Since I am very much a visual person, I would assume you mean something like this when you speak of a resistor divider. The output value is the voltage difference between amp's output and its reference. Search for examples of the chips use. However I appreciate any guidance given on this project.

Smart Hook can be easily attached to all kinds of telehandlers, giving users a Crosby swivel hook that incorporates a wireless load shackle positioned at the center of a in. My understanding is the while under strain, the load cell measures the change in resistance.

The support bars transfer the weight of the quadcopter to the load cells. Even a crude drawing in mspaint would help, things are much better explained visually for me. Further, it gives an accurate load measurement without confusing set-up or programming. When the test stand was reassembled in the new shop the support bars were completed.

The Smart Hook allows the operator to weigh the load and consult their load chart before starting a lift. It would be great to be able to see a diagram of how I can relate the load cell, amp, and Arduino together, I can understand the mapping of circuit diagrams. The support bars are setup to accomplish this.

Once I got the reading with the quadcopter on the load cells, I then weighed the quadcopter using the scale. With the two readings and two weight measurements, I now have a calibrated setup where I can weigh the quadcopter and measure the thrust produced. The next step will be securing the hardware and making so that I can read the thrust measurement while the quadcopter is running. The final step was calibrating the load cells.

Here's a shot of the electronics connected to test stand. This measurement is initially very small to my understanding and that is why an amp is needed. Since I'm still prototyping, I decided for now to assume symmetry from left to right of the quadcopter and only hook up the load cells on the right side of the support bars.
