Lift, camera, action! Dropping aircraft at NASA Langley Research Center

LC---dropping-aircraft

 

Sometimes, a story comes our way that just makes you wish you worked for NASA! Their Landing and Impact Research Facility at Langley includes a massive steel gantry, originally used to train Apollo astronauts to land on the moon. In the 1970s, the massive 240ft high structure was used to establish aviation crash testing techniques.

Getting tired: potential fatigue failure in load cells

LC---Fatigue-failure-LoadCells

Load cells are extremely hard-working and robust tech, designed to be in continual use for extended periods of time, with the minimum of maintenance and care required. With regular recalibration, your load cells can last for years even in challenging conditions. However, even load cells can become fatigued through rapid and repetitive loading and unloading, due to their metal construction.

Polar bears and load cells [Updated February 2020]

LC---weighing-polar-bears

One of our most popular articles has been this one - how to weigh a polar bear. So, with International Polar Bear Day approaching on Thursday 27th February 2020 (6a), we’ve updated this classic article with new information - and links to some great new pictures!

It all started with a simple question: had load cells been used in any form of polar bear research, given the extremes of temperature in the bear’s native Arctic, and the challenges of performance and data storage extreme cold presents.

Pancakes: flipping formulas, world records and low profile load cells

LC---pancakes

As Shrove Tuesday approaches, many of us will be gearing up for an evening of throwing half-cooked pancake batter in the air in the vain hope that it returns uncooked side down to the pan rather than sticking to the ceiling.

At The Load Cell Shop, every day is pancake day, of course! Our pancake load cells, aka low profile load cells, are ideal for a range of industrial measuring, testing and laboratory applications. Low profile load cells resist extraneous loads including bending, torque and side loads. So, pancake load cells are highly effective for fatigue testing, test rigs and for force measurement testing. Our low profile load cells are available in a wide range of capacities from 2.5kN to 300kN, and are compatible with our load cell bases.

Replace or recalibrate? Ensuring load cell accuracy

LC---Load-cell-calibration

Load cells are pretty robust pieces of kit, designed to withstand continual use in a variety of conditions, from underwater to freezing temperatures. However, their accuracy diminishes over time, and they do not last indefinitely. So, if your load cells are not performing as well as they did, what should you do?

Burning issues: load cells and bush fires

LC---Bushfires-Jan-2020

The Australian bush fires have dominated the news this month, and despite some very welcome rain and cooler temperatures in the last few days, the emergency is far from over. Our article this month investigates how load cells are helping scientists research the effect and possible solutions for wild fires.

 

A wind tunnel for studying wildfires

Wildfires are, buy their very nature, unpredictable and affected by natural factors such as wind, vegetation type, the land topography and more. A team in Canberra built a dedicated fire-proof wind tunnel to allow them to safely study of fuel combustion during a bushfire by reproducing a range of conditions. Load cells were, quite literally, taking centre stage in this project.

Bread and butter: load cells in the food industry

LC---Dec-2---xmas-food-2

If, like us, you’ve been glued to the TV series “Inside the Factory”, you’ll know just how much food production is mechanised and automated, from mixing ingredients to final packaging.

A new bread production line launched in the USA uses load cells under a conveyor belt to measure precise weights of dough. It allows bakers to divide up large quantities of dough within a single line. The dough line is headed up by a feeder that “Adjusts the dough sheet width depending on the products being made, thereby reducing the amount of trim and increasing quality. The line can either divide the dough pieces by dimension or accurately cut by weight.”

Braving the storm: calibrating load cells in marine environments

LC---Dec-1---calibrate-marine-1

Load cells are used extensively in marine environments, from the legs of oil rigs to cranes loading container ships. Load cells are effectively self-contained, so can be manufactured to be totally waterproof and work reliably even when submerged for long periods.

One of the issues in marine environments is that a lot of equipment will be naturally in motion due to weather, tides and wave action. This is particularly true for mooring winches, which are used to tie a ship to its berth when in port. When a ship is loaded or unloaded, or in a high swell, the winching ropes can suddenly tighten or loosen. If the cables were held at a fixed length, they could easily snap or be damaged, even given their own natural elasticity.

Did the earth move for you? Load cells and landslides

LC---Nov-2---Landslide-1

Land slides may not be that common in the UK, but they can be incredibly disruptive when they do happen. The recent heavy rain, for example, caused a land slip on the main rail route into from London to Southampton, and required some major earth removals before the services could continue. Luckily, load cells can play their part in monitoring structures holding back the flow of earth.

Freight and weight: load cells keeping truckloads legal and safe

LC---Nov-1---HGVs-1

How much weight is that truck ahead of you on the motorway actually carrying? Do you know? Does the driver even know?

Legal load limits in the UK

All goods vehicles have a weight limit, known as the Gross Vehicle Weight (GVW). However, because its based on plated (maximum) weights for each individual axle, if the load on the truck isn’t balanced properly. Therefore a load might be illegal because it’s in the wrong position rather than over the GVW.

Load cell round up; old cranes, oil pumps and how to kill a lithium ion battery

LC---Oct-Roundup-1

Three neat little news stories showing the versatility of load cells.

Old tech, new tests

All over the globe, there are machines that have worked hard for decades, using long-established techniques, and can continue to work well for the business. All they need is a little TLC, regular maintenance, and calibration or adaptation for special tasks.

A ringer cranes at a ship in Malaysia, originally built in 1973, was required to load anchor piles onto a ship, bound for a new oil and gas floating production storage facility. The crane, with a capacity of 308t at 24m, needed to be tested to lift 108t of weight 1 metre above the ground at a 41m radius.

These are a few of our favourite things: load cell stories you might have missed

LC---Sept-Roundup-1

Every month, we seek out the latest and most interesting stories on load cells to include in our articles. Here are just a few of our favourites.

 

Equine health and wellbeing

Load cells play a remarkably prominent role in the measurement of forces involved in equine sports. The focus is shifting from health issues such as hoof problems to assessing and measuring the impact of elements of traditional horse tack such as reins, bits and girths.

Rockets, planes and sewers: load cells on the level

LC---Nasa

Load cells are at the heart of three very different projects that involve keeping element on a level plain, including a NASA rocket, a sewer shaft and a airplane assembly line.

 

Turning space rockets on their side

If you’ve ever had your project specs changed halfway through, spare a thought for the team at Boeing building the new NASA Space Launch System (SLS) Core Stage.

In order to, quote, “cash in on the schedule benefits of the new plan”, the carefully constructed engine section needed to be turned from its current vertical position to lie horizontally. It may have only be a 90 degree turn, but according to an incredibly detailed article at NASASpaceFlight.com, the process involved modifying existing tools and creating several new ones within just a few months.

A gentle touch: load cells in medical devices

Copy-of-LC---research

Many medical devices rely on accurately measuring force, enabling adjustments to be made either automatically or manually. What makes accurate measurement so crucial is that many of these devices are now available for patients to use at home, without a doctor or health professional available.

Equally, load cells have been playing a central role in the research and development of touch-sensitive prosthetics and the understanding of how our sense of touch can affect our body posture and accuracy of movement.

Load cells on the road with major musicals

LC---theatre

One of the UK’s most popular West End musicals, Andrew Lloyd-Webber’s The Phantom of the Opera, (https://uk.thephantomoftheopera.com/) is out on the road in the UK and Ireland next year, no doubt with a full set, impressive lighting and, of course, that pesky chandelier!

The US tour of The Phantom of the Opera back in 2015 featured an extensive lighting and sound rig featuring over 200 speakers, 85 moving lights and 10 tons of scenery, all loaded onto 20 trucks. That’s a lot of weight suspended above the performers’ heads, and a lot of load for theatre roofs and scenery towers that can date back to Victorian times.

So, in almost every modern stage or concert rig, load cells are playing a vital role in weighing the rig to ensure it stays within the venue’s capacity, and monitoring load distribution during rigging and performances.

Phew what a scorcher: load cells and temperature effects

LC---heat

Once again, Europe is bracing itself for record high temperatures in June - and this weekend we’ll get a whole day of the heat ourselves (well, most of the UK will anyway).

Whilst the media might be ramping up for pictures of Parisians in fountains or Romans in baths, UK businesses might be assessing the effect of high ambient temperatures on their equipment, processes and products.

If you’re using one of our load cells in an outside environment, it won’t even be breaking a sweat at 45 degrees C, the projected temperature for central Europe. Even in the heat of the Middle East and Africa, where temperatures regularly rise above 50 degrees C, it’ll still working just fine.
