Pit Type Steel Weighbridge by Nipro Weitek

Overview

About the Pit Type Steel Weighbridge

The Nipro pit type steel weighbridge is installed in a prepared pit so the steel deck sits level with the surrounding road. Trucks drive straight on and off without ramps, which keeps traffic moving at busy gates and suits sites with limited approach space.

The platform is built from heavy-duty structural steel sections and rests on high-precision digital load cells. Every weighbridge is designed for use with weighing software, slip printers, RFID and automation systems, so it can grow with your operation.

Applications

Where it is used

Public Weighbridges, Toll & Check Posts

The Public Weighbridge software version produces customised tickets, and we assist with legal metrology stamping.

Manufacturing

Weighbridge and process weighing data can be integrated with SAP, ERP or Tally for one source of truth.

Steel & Cement

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

Installation

Site & installation requirements

Requires a civil pit built to our foundation drawing, with drainage so water cannot collect around the load cells.
The platform sits flush with the surrounding road, so vehicles can enter and leave from either direction without ramps.
Our team shares the drawing, checks civil readiness, then installs the platform, load cells and indicator and commissions the system.
Ready precast foundation blocks can be used to shorten the civil work.

How our installation and maintenance works

FAQ

Questions about this product

A pit installation keeps the deck level with the road, so vehicles drive on and off from either direction without ramps. It saves space at busy gates and suits sites with limited approach length.

Keep the pit drainage clear so water cannot collect around the load cells, and remove debris from the gaps between the deck and the pit walls. Our annual maintenance contract includes periodic inspection and calibration.

Standard platforms run from 7 m to 18 m long and 3 m wide, with capacities up to 200 t. Custom sizes can be built to suit your longest vehicle.

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.
