Adoption stage for autonomous Bell ADTs

Autonomous Bell ADT

UK quarries among those set to introduce autonomous articulated dumptrucks during 2023

FOUR years after commencing extensive testing, global ADT specialists Bell Equipment report that autonomous technology is now at the adoption stage with more customers in the UK, South America, and Australia set to introduce autonomous Bell ADTs during 2023.

‘We’re extremely excited to have reached the adoption stage,’ said Bell Equipment product manager Brad Castle. ‘Right now, we are working closely with one of our UK customers. They are a leading mobile plant supplier and earthmoving contractor that has a large existing fleet of Bell ADTs and is looking to initially install an autonomous system on to two B30Es for a quarry application. Initially, they will be introducing autonomous ADTs on two of their sites as part of a continuous drive to improve safety.

‘At the same time, we have a mining customer in Australia who will be introducing five autonomous Bell ADTs later in the year. Both these customers have chosen xtonomy as their preferred guidance system.’

Mr Castle explained: ‘Providing autonomous-ready machines will be a part of our core business in the future, but in terms of sensing and guidance systems we decided that it makes more sense to partner with market leaders and innovators, as we do with drivetrain, hydraulics, and electronics technologies in our trucks. Bell currently have two approved service providers, xtonomy based in Europe and Pronto AI in the US, both of which can work with Bell customers from anywhere in the world.’

Xtonomy have had B30Es operating autonomously in the Alps since 2020. Pronto have established two test sites in the US, one at a Texas sand mine and another in Reno, Nevada, where three autonomously operated Bell B45Es and a Bell B50E are working in a quarry. In addition, they will soon be establishing a demo site in South America.

‘As part of our strategy to enable interoperability between our ADTs and various control systems, so that customers have a choice of third-party suppliers, we have recently engaged with a third supplier and hope to begin testing this system later this year,’ added Mr Castle.

The xtonomy and Pronto AI systems, although both autonomous, offer different benefits depending on a customer’s needs.

‘Xtonomy have vast experience in the autonomous field with years of stable testing. They offer a complex radar-based system, which is less affected by inclement weather, but requires higher upfront costs and relies on the loading tool operator to manage the operation,’ said Mr Castle. ‘However, the continuous site and object mapping, with minimal manual interaction, makes the system well-suited to multiple load and dump sites. In addition, the advanced in-cab display and supervision screens allow for easy integration with other equipment on site to provide a fully autonomous offering.

‘Pronto AI, on the other hand, offers quick deployment with a much simpler, integrated system that has subscription-based pricing with minimal upfront costs. Theirs is a camera system and the non-dynamic site and object detection require manual interactions. However, it is controlled by a user-friendly mobile app and routes can be easily changed by manually driving them. It is also possible to run this system over a private LTE network.

‘The beauty of both systems is the flexibility they offer our customers. Bell provide a standard cab with no extra hardware taking up space to create an environment where manual, remote or autonomous operation is interchangeable. This means that once an ADT has finished a contract on an autonomous site, the sensory and control system can easily be removed and the truck either fitted with a new system for another site or used in a manual operation.’
