Expansion Continues for LCM Systems and Customers Benefit from Increased Product Ranges

A combination of customer demand for our ex-stock and customised load cell products and an increase in the number of the market areas served, has resulted in major investment here at our Isle of Wight HQ. Since the start of 2012, our manufacturing and storage facility has increased by 70%, providing an expansion of the testing facilities, as well as an increased area to hold next day delivery load cells and instrumentation. An increase in the workforce over coming months will further strengthen LCM Systems’ expansion plans.

We have seen a steady increase in demand for our customised load cells from a range of different market places, especially our heavy duty shackle load cells for the offshore oil and gas industry. The manufacture and testing of these large sensors require additional space and so we have expanded our facilities by purchasing the next door unit. Consequently, we are now able to handle an increase in orders and the extra space has also meant that we have substantially increased our storage facilities so customers can benefit from a larger range of products available to be dispatched ex-stock.

 

The EDF Energy London Eye Capsules Lowered Safely and Steadily Thanks to an LCM Systems Load Cell

As any company, I like to write about interesting applications in which are load cells are used. But often customers can be quite wary of giving away too much information and I quite understand this. However, if the application is not sensitive, talking about it can be great publicity  for your company. We employ an experienced and professional PR team at In Press who will be able to put together the story on your behalf and get it published in the relevant media. So, if you would like to work with us to gain publicity for your company and the work that it does, then please contact me.

Here is an example of joint publicity we completed with EDF Energy on a great project we did on the London Eye. EDF and their publicity department had final say on the copy and we had it published in a variety of different journals throughout the trade and technical sector.

LCM Systems Helps EDF Energy London Eye Project

Since 2009, The EDF Energy London Eye, the UK’s number one paid-for visitor attraction, has been going through a £12.5 million upgrade that is set to further improve the visitor experience, increase environmental credentials and ‘future proof’ one of the UK’s most iconic landmarks for years to come. The work will be completed in time for the 2012 London Olympics.

This complex project, which involves removing each of the 32 10tonne capsules in turn, has over 20 companies working on design, planning, sub-projects and logistics. The owners of The EDF Energy London Eye, Merlin Entertainments Group were committed, wherever possible, to use UK businesses and this has been achieved thanks to the enormous amount of UK industrial expertise.

Companies such as Isle of Wight-based LCM Systems have played a small, but crucial part in the process. The company is known throughout the world for designing and manufacturing a wide range of load cells for a variety of lifting and weighing applications. Its part in the upgrade programme involved providing a shackle load cell and TR150 hand-held indicator to ensure that when a 10tonne capsule was removed from the cantilevered observation wheel, it could be safely and securely lowered on to the pontoon that was waiting to transport the pod up the Thames.

The capsules are attached to wheel via 4 pins that need to be extracted before the capsule can be removed. The process involved attaching the load cell onto an air hoist that was in turn attached to the capsule. Air was driven into the hoist until the load cell gave a reading of 10.5tonnes on the indicator, monitored on the ground by an experienced engineer. Once engineers were satisfied that the capsule was secure and could be lowered safely, the pins were extracted and the pod began its controlled descent. Without a safe and reliable load cell, the weight of the capsule would be unknown.

Mark Robinson, Technical Operations Manager at EDF Energy London Eye, has been very pleased with the performance of the LCM load cell. “Although a relatively small part of the overall operation, it is vital that the load cell is reliable and accurate. We have also found it is easy to install and operate, with the digital indicator enabling us to monitor the load from the ground.”

The SHK-B is one of an innovative range of shackle load cells designed specifically for lifting and weighing applications in harsh or rugged environments.  LCM Systems can provide the cabled versions with Crosby shackles as standard or as an option with Greenpin shackles. Safety is paramount for the demanding applications in which these shackle load cells are used and the use of high-quality shackles is essential to comply with safety standards and regulations as well as to maintain integrity.

All shackle pins are forged from high tensile carbon steel and proof loaded to 150% of the normal rated load. The products are sealed to IP66 to protect against harsh weather conditions.

The TR150 handheld load indicator used in the project is a versatile and intuitive precision instrument. It is a portable, environmentally sealed unit that has been specifically designed for accuracy and versatility.

With only six keys to access, the operator can easily set up the unit and the configuration menu enables the setting of a tare value, display resolution, filter rate, auto power off and selection of low power mode – all through the front panel. This menu option also enables the user to tailor the instrument’s response to the application. The TR150 accepts an input range of up to 50mV/V and two separate ranges are available which means that the instrument can both read and display two separate parameters. In each range all the variables can be set, including zero and filtering.

 

Custom Designed Shackle Load Cells for Offshore Mooring Tension Application

As well as providing a comprehensive range of standard load cells, we have highly experienced in-house design engineers who time and time again have demonstrated their ability to meet both the commercial and technical requirements of clients. For one offshore engineering systems integrator, we provided a complete shackle load cell solution designed to match stringent criteria, complete with full American Bureau of Shipping (ABS) traceability.

The enquiry was made by a long-term client who had previously bought load pins from LCM to be installed into shackle and pin assemblies already on site. This project was to provide a complete shackle load cell solution for measuring mooring tension but there were some important criteria that needed to be met.

Firstly, the load cell had to be a shackle type, designed to fit into an existing link plate and the pin had to be manufactured from 17-4PH stainless and withstand full submersion to 500psi. Secondly, material and proof load certificates were required for the shackle, with the load pin requiring full traceability to pass inspection by the ABS. Additionally, all cables had to be robust and protected.

The result was the LCM3064 150te subsea submersible D-type shackle load cell that answered all the criteria. The load cell was designed using a GN Rope H11 shackle rated to 150te, with the pin manufactured from 17-4PH stainless steel. It also featured a mating 10m subsea moulded connector cable assembly, protected by heavy duty, steel reinforced hydraulic hose and a special anti-rotation bracket to loop back the hose for the correct cable path. In order to ensure the load cell would fit into the existing assembly, loose spacers were supplied for added flexibility when it was installed into the widely toleranced link plate.

We offer a wide range of standard shackle load cells and also have an extensive selection of custom design versions, which could also be used to satisfy other applications. Many of these products are also supplied with LCM Systems’ TR150 handheld battery powered indicator, with built in analogue signal conditioning, digital outputs or wireless telemetry. Customers are also able to specify a particular shackle that they wish to use, including the renowned GN Rope, Crosby and Greenpin. Here at LCM, we will either supply the complete solution or design a load pin to suit the specified shackle.

Don’t Just Buy A Load Cell …..

tell us your application because you never know, we may be able to help with a better solution to your problem.

I say this because recently I had a little chuckle when talking to a customers of ours about their particular application. We sell a lot of our load cells for lifting and weighing applications, particularly for cranes. In this case, the customer had installed some equipment for load monitoring with the readout on the ground, this meant that when the crane was holding its maximum load, someone on the ground had to shout up to the man in the cab that the limit had been reached. Obviously this has lots of drawbacks, not least that it becomes a two-man job and requires vigilance and a loud voice! By using a load cell with a telemetry/wireless option, then the operator can see directly that the load limit is being reached and can plan his actions accordingly.

It’s a win-win situation. You tell us your application and we can suggest the best possible solution, either from our standard range or a customised  solution from our in-house designers.

So, you can shout about that :-)

How Do You Decide Who To But Your Load Cells From?

I know this is a very difficult question to answer, but it is one I often find myself discussing both internally with people here at LCM Systems, my marketing people and friends down at the Golf Club. What makes people decide to buy? And in this case, I am talking about technical and engineering products.

Sometimes it’s obvious, the company you buy from is the only one that offers the exact product for your precise application. We often find this when engineers approach us for sophisticated and complex weighing systems, our design engineers are the only ones who truly understand what is required from the load cells and how they can seamlessly integrated to solve their application conundrums.

But what else drives people’s buying decisions? Of course, a product that is used in critical applications, particularly those with heath and safety implications need to be of the highest possible quality, otherwise lives could be at risk. I’ve written about this in a previous blog on LCM Systems’ Shackle load cells.

What about some of the intangibles? Is it important to you that our products are manufactured in the UK? Is delivery a key factor? What about price, is that the be all and end all of your search for load cells? With our internet sales growing year on year, I suppose it is also easy to forget that some people find that having a knowledgeable, helpful and friendly voice at the end of a phone to guide them through their buying decision is a major factor in deciding what company they buy from.

I’d love to hear from you. What is your Top 5 list of what influences your buying decision with respect to your engineering components? And most importantly, if you buy from LCM Systems, how do we rate?

Decisions, decisions

Reject the Throw Away Culture – Safety is All Important

We are all very aware of today’s throw-away culture. In her recent book the Story of Stuff, published in May 2010 in the UK, Annie Leonard discusses how only 1% of products that we buy are in use 6 months later. You can see her talk about it in this excellent short animated discussion at The Story of Stuff.

But it’s not just the consumer culture that is to blame for this huge wastage. Many of us want to follow the latest fashions, be they in the consumer world or business to business sector. Because fashions come and go, products are often made without much regard to quality so they can be sold cheaply. And here lies another problem – cost. If something is only going to be used for a short space of time then what’s the point in spending a lot of money on it?

But, and here is my point, what if the product is meant to last and its failure would have serious safety implications? The “pile ‘em high, sell ‘em cheap” culture cannot be applied here, can it? Unfortunately it often is.

I know negotiation on price is part of business but compromise shouldn’t be. Take for example the LCM Systems’ shackle load cells for lifting and weighing applications in harsh, rugged industrial environments. Known throughout the world as manufactured to the highest possible specifications in high tensile carbon steel and using Crosby or Greenpin shackles, there is no doubt that they can do the job, day in, day out without any safety or quality issues. So why are people buying cheaper? LCM Systems is not the only company (unfortunately ;-) ), who sell such high quality products, so it’s simply a matter of choice.

It really is a case of Caveat emptor – Buyer Beware. The cheap shackle load cells you are buying may claim to be equal, but is the safety of your personnel and the reputation of your company worth saving a few hundred dollars or pounds?

When quality, reliability and accuracy are essential, please check out the credentials of the company you are buying from – it could save someone’s life
