Pit Type Weighbridge
A weighbridge installed flush with ground level inside an excavated pit — no ramps, level access from every side, and a compact footprint for space-constrained yards.
Capacity: 5 MT to 100 MT (configurable)
Pit type weighbridge — flush, space-saving, and easy to approach
A pit type weighbridge (also called a pit-mounted weighbridge) is installed flush with ground level inside an excavated pit, so the weighing deck sits level with the surrounding surface. With no approach ramps, vehicles can drive onto it from any side — which makes it the natural choice for yards where space is tight or traffic flows from several directions.
Caliber Scales manufactures pit type weighbridges from 5 MT to 100 MT, engineered for accurate, dependable weighing in demanding industrial conditions.
Why choose a pit type design
- Saves space. Without ramps, the weighbridge occupies only its deck footprint — ideal for compact or congested yards.
- Level access from all sides. A flush deck lets vehicles approach and leave from any direction, easing traffic flow at busy gates.
- Low profile, low wear. The ground-level deck reduces wear and keeps the site clean and unobtrusive.
- Built to specification. We engineer the pit, foundation, and drainage to match your vehicles and site conditions.
How it works
The steel weighing deck rests on load cells set within the pit. As a vehicle drives on, the load cells convert the weight into an electrical signal that a pre-calibrated digital indicator processes and displays on an LED, GLCD, or TFT screen — ready to print, store, or pass to your weighing software.
Instrumentation and options
- Pre-calibrated indicators with intelligent terminals
- Connectivity over RS232, RS485, Ethernet, and USB
- IP cameras for weighment photo capture
- Vehicle-positioning guidance and weighbridge software
- Lightning protection for exposed installations
Applications
Pit type weighbridges suit space-constrained logistics yards and plants in cement, steel, and manufacturing — anywhere a flush, ramp-free approach is preferred and the site can support proper pit drainage.
Pit type vs surface mounted
If your site has drainage or groundwater concerns, a surface mounted weighbridge may be simpler. For very heavy, continuous traffic, consider an pit type weighbridge. We will recommend the right design for your yard — see the full weighbridge range or request a quote.

Comparison
How the two most common weighbridge designs compare at a glance.
| Surface mounted | Pit type | |
|---|---|---|
| Installation | Above ground on ramps — no excavation | Set flush into an excavated pit |
| Civil work | Lower — raised foundation only | Higher — pit excavation + drainage |
| Yard space | Needs approach ramps | Saves space; level approach from any side |
| Maintenance access | Open underside — easy to clean & service | Access within the pit |
| Drainage / groundwater | Well suited to high-water sites | Needs good drainage design |
| Typical lead time | Faster to install | Longer (civil work) |
Frequently asked questions
What is a pit type weighbridge?
A pit type weighbridge — also called a pit-mounted weighbridge — is installed inside an excavated pit so the weighing deck sits flush with the surrounding ground. With no ramps, vehicles can drive on from any direction, making it ideal where yard space is limited.
How much space does a pit type weighbridge save?
Because there are no approach ramps, a pit type weighbridge needs only the deck footprint, freeing up the ramp area a surface mounted design requires — valuable on tight or busy yards.
Does a pit type weighbridge need drainage?
Yes. As the structure sits in a pit, proper drainage is essential to keep the foundation and load cells dry. We design the civil work and drainage to suit your site.
