Onboard Weighing Systems for Civil Construction

Onboard Weighing Systems for Civil Construction

Onboard weighing systems play a vital role in optimising productivity for projects in the civil construction industry. The RDS MME Loadex 100 excavator weighing system is just one example of this, designed to operate in the fastest loading environments and perfect for the complex nature of civil construction.

Civil construction, a branch of Civil Engineering, is defined as the maintenance, design, and development of natural and physically built infrastructure. This includes projects concerning railways, buildings, roads, water reservoirs, airports, sewer systems, and dams.

Civil Construction: Why Onboard Weighing is Important

As with any industry, onboard weighing in the context of civil construction has massive benefits for increasing focus and productivity. Given the highly complex nature of their logistics, civil construction projects are often on tight schedules that require high levels of efficiency to avoid delays and schedule pushbacks – both of which will result in extra costs.

There are numerous advantages of using onboard weighing systems to aid a civil construction project and the cloud-based Sitelink3D-enabled Weighing Solution helps weigh and track the movement of materials on and between zones.

A combination of hardware, online tools and pay-by-the-day app-based functionalities keeps users aware of weights, loading and dumping zone activities, routes, cycle times, important averages and other critical information for real-time decision making, costing, billing and scheduling.

The system makes it easier to ensure equipment, trips and profitability are optimized. Automated load weighing and logging are safer, faster and more accurate than other tracking methods. Plus, the system is automatically updated in real-time making it easy for project managers or other stakeholders to remotely manage multiple drivers, operators and projects in real-time.

The Loadex and Loadmaster weighing systems can be mounted on haul trucks, excavators and wheel loaders.

  • Accurate weighing in difficult conditions and terrains.
  • Aids construction practices such as cut and fill excavation.
  • Geofenced locations provide auto product recognition and ensure material is dumped at the linked destination.
  • The ability to set individual product targets to ensure the correct loading of trucks.
  • Enhanced efficiency that reduces product wastage.
  • Real-time weight and load monitoring.
  • Load and equipment optimization.
  • Remote visibility of job sites.
  • No subscriptions or paying for unutilized machines.
  • Safer, faster and more accurate than other tracking methods.
  • Actual versus projected scheduling adjustments.
  • Billing and estimation validation/accuracy.

Loadex 100

The Loadex 100 can be retrofitted onto both tracked and wheeled 360-degree excavators to weigh the amount of material in the bucket.

It has been designed to operate within the fastest loading environments to maximise tons per hour performance. A correct first-time loading of a dump truck will reduce vehicle movement, fuel usage, and machine & tyre wear.

How does it work?

Two pressure sensors  measure forward and return pressure in the hydraulic lift circuit. The pressure signals are captured, filtered, and corrected by measuring the angle of the main boom, dipper arm, & machine chassis. A gyro sensor measures the effects of slewing.

When used dynamically, the pressures are captured through a set weighing zone. The system can also be used in static weighing mode, in which the boom can be lifted to a set weighing position where the pressure is captured or measured constantly in a “live” mode at any required boom height. Both dynamic and static weighing positions are adjustable by the operator to suit the job, which will enable the machine to be used at its most efficient output.

All calculations are made in the weighing module and sent via CAN protocol to the terminal in the cabin. Load and store information is saved here and can be sent to Sitelink via 4G or wi-fi.
