The weight-based billing revolution

On-board weighing systems are increasingly becoming a mainstream choice for small and medium operators alike.

From eliminating payment disputes to monitoring profitability and increased compliance, weight-based billing (WBB) is revolutionising the way the industry measures its loads.

As the national distributor for Trimble LOADRITE E2750 weighing systems, Weighing Systems Australia has seen the technology’s benefits first-hand.

According to Alan Clarke, Owner of Weighing Systems Australia, those not transitioning to onboard weighing systems are now the exception rather than the rule.

“A lot of major contracts issued now have a requirement for a weighing system as part of their contract,” Alan says.

The benefits are increasingly becoming a no-brainer for many companies, as Alan says that up to 80 per cent of customers are choosing legal-for-trade systems. This includes waste generators and small and medium-sized enterprises.

“A lot of fleets are deciding which of their trucks need retrofitting or replacing and putting weighing systems on when they order a new truck,” he says.

Alan says that onboard weighing is important to ensure accurate weights are measured and customers are charged accordingly for overloaded bins and to do this the weighing system must be a National Measurement Institute (NMI) approved scale system, in addition to reducing fines and improving safety.

He says that weighing is not only essential for quantifiable profit margins, but ensuring compliance with Heavy Vehicle National Law Chain of Responsibility laws.

“WBB as it is called now also takes into account the ever-increasing cost of landfill charges and haulers must be able to identify what each clients bin actually weighs.”

Alan says that the legal for trade system allows for Class IV NMI approved systems to be installed into both front and rear lift waste collection vehicles.

Monitoring profitability is particularly important for major retailers, Alan says, as they can ascertain what they waste internally by measuring the waste removed from sites.

Payment disputes can also be prevented by being able to check, certify and stamp legal for trade records that have been calibrated to accurate weights.

Alans says a variety of configurations are available, including front and rear lift certified and non-certified systems. He says that all new refuse collection trucks now have on-board computers that collect time, weight and date and allocate these to the specific customer selected in the routing system ready to be downloaded to the office.

Solid state positioning sensors over traditional rotary triggers are also emerging as a mainstream choice for customers. Alan says the E2750 Canbus sensors include arm and fork sensors. Alan says these are easier to install, with the ability run one cable instead of multiple cables, making installation easier and less prone to cable breaks and damage when compared to older sensors.

He says the systems are also notably fully dynamic and don’t slow drivers down.

“Fully dynamic weighing systems have an advantage over static systems where the driver has to stop to weigh up and down. This costs them time and slows down their operations,” he says.

Alan says that the systems can be easily fitted to all makes and models. When it comes to after-sales support, Weighing Systems Australia offers annual calibration services and has distributors across the country in a nationwide dealer network.

Mobile shredding system for alternative fuels and biomass

The new XR3000 mobil-e capitalises on the benefits of an electromechanical drive without having to forgo the advantages of a mobile machine.  

Available through national distributor FOCUS enviro, the machine aims to provide operators with maximum efficiency and flexibility.

Just like all UNTHA XR products, the XR mobil-e is equipped with an energy-efficient UNTHA Eco Drive. This ensures minimal operating costs and maximum material quality.

A key feature of the machine is that it operates only electrically, conversely to energy consuming, and at times, noisy diesel operated alternatives. 

For the shredding process, the XR mobil-e is connected to the power supply with a hands-on quick fastener, allowing the machine to be moved across a variety of indoor and outdoor locations.

Mobility is ensured through a reliable crawler-type undercarriage in combination with a small petrol-powered engine. The XR mobil-e can be easily moved to any spot via remote control. With an extensive range of interchangeable screens and cutters, the shredder can be configured according to the customer’s output specification. 

For example, consistent 30-millimetre or 400-millimetre particle sizes are achievable, as is anything in between. This means the XR mobil-e can shred bulky, municipal solid waste, commercial and industrial, construction and demolition or wood waste with ease. Other applications include industrial waste, scrap wood, plastic bales and more. 

The machine also produces a homogenous alternative fuel to the waste-to-energy, cement, gasification or biomass markets. In addition, a height-adjustable discharge conveyor belt and an optionally available magnetic separator lead to an efficiently operating mobile shredding system.

Genox Shredders from Applied Machinery

Applied Machinery offers a diverse range of Genox shredders to process an array of waste streams down to specific sizes. 

For size reduction of flexible, medium hardness, voluminous products, Genox’s K Series Single Shaft Shredders process various plastics (films, mouldings), paper and cardboard, copper, aluminum, textiles and a range of other applications. The M Series shredder, which performs largely the same functions, is suited to other potentially contaminated materials such as metals or stones.

When it comes to small and medium size reduction, the Genox V Series Single Shaft Shredders are capable of processing a wide range of materials to uniform particle size. Typical applications include plastic, timber/wood, paper and cardboard and copper. 

If operators are looking to process large volumes, then the X Series Twin Shaft Shredders works as an ideal pre-shredder for municipal solid (MSW) and commercial and industrial (C&I) waste, scrap metal, end-of-life vehicles and a range of other applications. Segmented blades greatly reduce blade changing time and cost. 

BH Series Single Shaft Shredders are heavy-duty reduction machines designed to process a variety of untreated waste materials down to coarse or medium-sized fractions. This powerful, wear-resistant machine is suited to demanding recycling tasks and can handle MSW, C&I, construction and demolition and other wastes.

Scania P-series

Scania builds on its history of providing robust urban workhorses suited to the waste industry with the arrival of its next generation P-series.

Available as a prime mover or rigid, in a variety of power train and drive train combinations, the Scania P-series offers high levels of safety, driver comfort and excellent visibility, critical for safe and fuss-free manoeuvring in built-up areas.

The new Scania P-series comes with a range of frugal Euro-6 low emission engines with up to 450 horsepower available, making it suitable for a wide range of tough jobs. The P-series has been a successful front lift or rear-loading waste trucks, as well as being fitted with various hooklift and skip bin systems over the years and has a well-established following within the waste industry. 

The high output six-cylinder engine easily pulls bulk compacted waste bins with high gross combination mass.

In the 2019 NTG P-series, the windscreen is larger, and the A-pillars and door mirror mounts are repositioned, providing far greater visibility at intersections.

As part of the launch of a more spacious, frugal, safer and efficient overall package, Scania is offering a five-year or 500,000-kilometre service inclusive package that provides fully predictable maintenance costs for operators.

And as supplies of the NTG P-series arrive in Australia, a small number of previous generation P-series 8×4 hooklifts remain available.
