Weighbridge Calibration, Repairs and Maintenance Packages

Your weighbridge is a critical control point. When it’s working properly, it protects your margins, cuts down on disputes, keeps you compliant, and keeps trucks moving through the gate. When it starts playing up or breaks down completely, you feel it straight away: queues at the weighbridge, dodgy tickets, rejected loads, frustrated drivers, and commercial arguments that burn time and money.

Micro Weighing Solutions covers everything you need for weighbridge support: calibration, breakdown repairs, maintenance packages, load cell replacement, and general upkeep. We keep it practical and focused on what matters at your site: get the accuracy back, cut the downtime, and stop the same faults coming back.

Keeping accuracy where it should be

Calibration isn’t about ticking a box. It’s about confirming your weighbridge is performing correctly and consistently across its full range. Even small errors stack up fast when you’re doing hundreds of weighments, and accuracy problems tend to creep in gradually. You might not notice until there’s a dispute or an inspector turns up.

How we Help

When we calibrate, we check the things that matter: zero stability, span performance, repeatability, and whether the weight changes depending on where the vehicle sits on the deck. If readings shift around based on truck position, if the weight drifts during the day, or if it won’t settle back to zero, your weighbridge needs looking at.

Not sure when you last had it calibrated? Seeing inconsistent weights? Give MWS a call and we’ll tell you what to do next.

Weighbridge Repairs: quick response, proper fix

Weighbridge problems usually get reported as “the indicator’s wrong” or “it won’t settle,” but the real issue could be in the mechanics, the environment, or somewhere in the electrical signal chain. Our repairs focus on getting you back up and running quickly, but we also fix what actually caused the fault so it doesn’t just happen again.

Common problems we see:

• Unstable readings jumping around when the load hasn’t changed
• Zero drift or the scale won’t go back to zero after a truck drives off
• Corner or position errors where the weight changes depending on axle placement
• Intermittent faults from damaged cables or dodgy connections
• Water getting in, debris building up, or drainage problems in the pit or structure
• Impact damage from heavy braking, trucks hammering onto the deck, or overloading

Once we’ve sorted the immediate problem, we’ll advise on practical improvements: better cable protection, cleaning routines, sealing up gaps, and how often you should be maintaining it based on your traffic levels and site conditions.

Load Cell Replacement: precision work, not just a part swap

Load cells are the heart of the weighbridge. They get damaged by shock loading, corrosion, moisture, cable faults, poor installation, and electrical events like lightning strikes. Load cell problems usually show up as unstable weights, repeated calibration failures, or unexplained drift that won’t respond to basic adjustments.

Replacing load cells properly is more involved than just swapping a part. MWS treats it as an engineered job:

• Confirm the fault through proper diagnosis so you’re not replacing good components
• Check mounting hardware, alignment, and mechanical constraints that might cause the same failure again
• Install and protect cabling properly to avoid pinch points, strain, and water getting in
• Check junction boxes and connections for moisture, corrosion, or poor terminations
• Complete post-replacement calibration and performance checks so you’ve got defensible accuracy

If you think you’ve got a load cell issue, dealing with it early usually saves cost and downtime. We see plenty of sites waste valuable time trying resets and quick fixes when the underlying problem is mechanical or electrical and needs proper attention.

Planned Maintenance Packages: fewer breakdowns, lower overall cost

Most weighbridge downtime is avoidable. The worst faults usually come from predictable causes: contamination under the deck, water management problems, cable wear, loose hardware, and gradual drift. Planned maintenance cuts down on emergency callouts, keeps accuracy tight, and helps your load cells and structural components last longer.

MWS maintenance packages can include:

• Scheduled servicing matched to your traffic levels and site environment
• Mechanical inspection of deck condition, check rods, mounts, and restraints
• Electrical health checks including cables, junction boxes, and signal stability
• Cleaning and housekeeping recommendations for pit clearance and drainage
• Planned calibration visits as part of a consistent accuracy programme
• Priority support for time-critical sites

A maintenance package usually makes the most sense for high-throughput sites where delays cost real money and accuracy needs to be reliable every single day.

General Weighbridge Upkeep: small habits that protect accuracy

A lot of weighbridge problems start with basic site conditions. Regular housekeeping makes a real difference to accuracy and reliability. If your weighbridge is in a pit, keeping drainage working and stopping debris buildup is essential. If it’s surface mounted, keeping the approach areas clean and stable helps reduce shock loads and improves consistency.

Simple upkeep that helps:

• Keep the pit and under-deck areas clear of mud, stone, and material buildup
• Check for standing water and sort drainage issues early
• Look for cable damage, loose connections, and signs of rodents
• Get drivers to enter and exit steadily, avoiding harsh braking on the deck
• Report changing behaviour early: drift, instability, slow settling, or inconsistent tickets

When to call MWS

If you’re seeing any of this, give us a ring:

• The same vehicle gives different results within a short period
• Weights drift throughout the day or after rain and temperature changes
• The scale doesn’t return to zero reliably
• Corner errors or position sensitivity across the deck
• Repeated calibration failures or you can’t get it to calibrate
• Water, debris, or contamination in the pit or around load points
• Visible cable issues, intermittent faults, or erratic indicator behaviour
