Compression cells discover load discrepancy

RIDDERKERK, Netherlands: February 2019. Lifting and rigging equipment rental company LGH Hijsmaterieel (LGH) used four compression cells from UK manufacturer Straightpoint (SP) to discover a five-tonne discrepancy in the weight of a magnetic resonance imaging (MRI) machine prior to transportation.

The MRI scanner measured 5.13 metres x 2.01 metres and weighed in at 21.17 tonnes compared to the paperwork supplied with the load that suggested it should have been 26 tonnes. As a result, the MRI was placed correctly on a trailer for the move by Wesdijk Exceptioneel Transport based in Alphen aan den Rijn.

LGH says the load cells and software are usually combined to verify the centre of gravity and weight of large and heavy objects that may not be evenly proportioned. The system captures the weight on each individual load cell, total weight, and centre of gravity, and displays it in a HTML report.

“The information was principally gathered for the crane team in Madrid who had to prepare their lifting tackle for offload,” explained Matthijs Senff, LGH sales engineer for Holland’s western region. “Jacking timbers were used to raise the scanner so the load cells could be positioned. The load cells were positioned and then a connection to the laptop was made. Upon configuration, the trailer was lowered to let the [MRI] unit rest on the load cells,” he continued.

“We frequently use our range of SP products in such applications. The equipment is cutting-edge technology and offers great user-friendliness onsite. Heavy lifting, onshore, and offshore industries, and the maintenance sector are among those utilising the technology for load tests and other applications,” he added.

The Crosby Group lifting and rigging company acquired SP at the beginning of this year.
