Pitless Type Concrete Weighbridge by Nipro Weitek

Overview

About the Pitless Type Concrete Weighbridge

The pitless type concrete weighbridge is a durable, above-ground weighing solution for industries that demand high accuracy, easy maintenance and long-term reliability. A reinforced concrete deck supported by a robust steel framework gives exceptional strength and stability for continuous heavy-duty vehicle weighing.

Because it sits above ground, the area beneath the deck stays accessible for cleaning and inspection — useful at dusty quarry, mine and ready-mix sites.

Applications

Where it is used

Mining & Quarrying

Above-ground pitless designs are easier to clean and inspect, and the Crusher & Mine software version handles material-wise dispatch.

Construction & Ready-Mix

Portable weighbridges and precast foundations reduce civil work and can move with the project.

Steel & Cement

Automated, unmanned weighing with RFID and ANPR keeps queues short and every transaction recorded with images.

Installation

Site & installation requirements

Installed above ground on a raised structure with ramps at both ends.
Load cells and electronics remain easy to reach for service and calibration.
The concrete deck is cast and cured on site to our drawing before calibration.

How our installation and maintenance works

FAQ

Questions about this product

A reinforced concrete deck is less prone to deformation than a steel deck, resists weather and corrosion, and needs little maintenance — a good fit for quarries, crushers and ready-mix plants.

For example, the 50 t, 9 m pitless concrete platform weighs to 5 kg. Accuracy depends on capacity, size and load cells, so we confirm it for your configuration.

Yes. Because the platform sits above ground, load cells and junction boxes can be reached without entering a pit.

Start from the heaviest fully loaded vehicle you expect to weigh, then add a safety margin for future vehicles. Platform length should accommodate the longest vehicle so all axles are on the deck at once. Our team will recommend a model once you share vehicle types, maximum gross load and daily traffic.

A pit-type weighbridge sits in a pit so the deck is flush with the road — vehicles drive straight on from any direction and no ramps are needed. A pitless weighbridge sits on a surface-level foundation with approach ramps, needs less excavation and makes cleaning and inspection under the platform easier. Ground conditions, drainage and space for ramps usually decide the choice.

Yes. Our weighbridges work with digital indicators, weighbridge software, RFID, ANPR, cameras, boom barriers and signal lights, so automation can be added at installation or as a later upgrade.
