The initial enquiry was received through our website from a multi-national marine engineering company, based in Canada. They had seen our standard TELSHACK-B product, but it did not suit their requirements precisely.
They liked the principle of a wireless telemetry shackle, but wanted to measure ship docking tension on a winch and the load cell had to handled by one person. This was hard to achieve with a conventional shackle, when the measurement range is 85te. A more compact solution was needed.
The main criteria we were given was as follows:-
|Rated Load (RL):||85 tonne|
|Proof Load:||95 tonne|
|Ultimate Breaking Load:||>180 tonne|
|Output:||2.4GHz Wireless Radio Telemetry|
|Transmission Range:||100 metres, clear line of sight|
|Power Supply:||2off Internal AAA rechargeable batteries|
|Battery Life:||200 hours of continuous use, between charges|
|Operating Temperature Range:||-20 to +60°C|
|Compensated Temperature Range:||-10 to +40°C|
|Zero Temperature Coefficient:||<±0.01% of Rated Load/°C|
|Span Temperature Coefficient:||<±0.01% of Rated Load/°C|
|Environmental Protection Level:||IP67|

The LCM3782 was designed using the standard wireless products used in our TELSHACK-B wireless shackle load cell as the basis of the product. Using our experience, which has been gained from more than 25 years experience in manufacturing load cells for harsh environments and with wireless telemetry incorporated, we were able to produce a product that met all of the customers requirements.
The LCM3782 is typical of many of the custom design products we manufacture, in that, our client identified a standard product from our range, which they thought would almost met their requirements. In discussing these requirements with our Engineers, we ensured it did.
LCM Systems 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 supplied with our TR150 handheld battery powered indicator, with built in analogue signal conditioning, digital outputs or with wireless telemetry.
We have manufactured shackle load cells based on many different shackle manufacturers' products, including; Crosby, Van-Beest, GN Rope to name a few.
