CASE STUDY
WEIGHBRIDGE - COMET QLD
PROJECT OVERVIEW
Slab Jack Industries spearheaded a weighbridge re-levelling project for a prominent sorghum wheat operation encompassing over 20,000 hectares. The existing weighbridge, vital for the efficient operation of a large-scale agricultural enterprise, had become inaccurate and uncalibratable. A thorough investigation revealed significant subsidence of the crucial bearing beams supporting the load cells, posing a challenge to accurate weight measurement. Faced with this complex issue, Slab Jack Industries responded with a reliable solution to restore accuracy, employing their expertise in concrete lifting.
SCOPE OF WORK
The initial survey for this works package was client supplied due to the remote Queensland location. The client has a large-scale sorghum wheat operation (+ 20000 hectares) which requires a road train capable weighbridge to be on site and operational.
The client’s installed weighbridge had become inaccurate, and not able to be re-calibrated. Upon investigation, the 500mm x 500mm x 4000mmL bearing beams supporting the load cells have been found to be subsided/undermined by approximately 15mm.
The 15mm subsidence was measured via dumpy level and supplied by client. Upon physical inspection of the weighbridge by Slab Jack Industries, the affected beams were found to be -12mm & -14mm from datum.
PROPOSED SOLUTION
The client required a solution that was capable of accurately re-levelling the 40000kg weighbridge, to within a +/- 5mm tolerance. Other factors to be considered were asset downtime and longevity of repair.
Slab Jack Industries proposed raising and re-levelling the bearing beams using structural lifting polyurethane.
Through careful analysis of supplied information and the clients clearly communicated requirements, the criteria for success was to be measured against the following benchmarks;
Levelling the affected beams longitudinally to within 5mm tolerance
Stabilising the beams using stabilisation polyurethane
Asset downtime of - 48 hours
Physical testing of weighbridge for operational accuracy post works
OUTCOME
Upon completion, operational testing confirmed the weighbridge's accuracy and fault-free functionality. The bearing beams, surveyed again using Zip Level Pro, demonstrated an impressive 2mm tolerance, surpassing client expectations by over 100%. Asset downtime was successfully minimised to just 12 hours.
