Keeping your Weighbridge maintained and clean is essential. Not only is it good practice to keep your bridge clean, but it also contributes to a preventative maintenance plan and can significantly reduce the risk of equipment downtime and inaccurate weighing.
Two levels of weighbridge maintenance should be considered to form part of your regular maintenance plan.
1. Basic Routine Maintenance
Weighbridge maintenance should take place as part of a regular routine depending on the type of site. The build-up of debris and water should be monitored and obstructions should be removed from beneath the bridge to provide clearance (at a minimum of 150mm) between the weighbridge and the ground.
Pit weighbridges should be checked to make sure clearances are clean and the correct gap between the deck and pit wall are maintained.
‘T’ section rubber is sometimes used to maintain gaps and should be replaced if worn or damaged.Before installing, it’s best to consult your specialised weighbridge expert, to ensure weight integrity will not be compromised.
Regular end-middle-end tests should be carried out to review the accuracy of the scale. This basic cleaning and maintenance can be carried out by a site foreman or weighbridge operative. If there is any difference or discrepancy revealed during the testing, it should be reported to your weighbridge expert.
2. Specialised Weighbridge Cleaning
Over time, build up of any product or debris can have a negative impact on a weighbridge’s performance. Compacted mud can set hard and reduce the movement of the weighbridge. This in turn causes reduced accuracy in weighing. Certain types of the site environment will suffer more with mud and slurry issues and weather conditions can also play a part. In these instances, professional weighbridge cleaning is advised to ensure the longevity of your product and your weighing accuracy.
SWIA can arrange a professional bespoke weighbridge conducted under the watchful eye of one of our expert technicians. This service can be provided during normal operating hours, but should be scheduled during quieter hours for a quicker cleaning process with less traffic.
Weighbridge cleaning is a highly skilled task and should only be performed by a trained individual with specialist equipment. The water jet force required to remove dirt and debris from around a weighbridge’s critical weighing points can, if not performed correctly, damage load cells and cabling. Attempting to clean your bridge yourself with pressure washing equipment can void a service contract if cells are damaged.
