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

15^th Dec 2011

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.
