Underloading a haul truck wastes a cycle; overloading one shortens frame and tyre life and, on many sites, voids the warranty. Tanberg's TR240 tries to settle the question at the shovel by reading hydraulic pressure in all four suspension struts and converting it to payload in real time.
The approach is not new, but Tanberg claims a tighter tolerance: plus or minus 1.5% once the truck has rolled 50 metres, against the 3% to 5% typical of earlier strut-based systems. The gain comes from compensating for grade, body temperature, and the oil viscosity shift between a cold start and a hot afternoon.
Lopsided loads show up first
Because each strut reports separately, the system also sees side-to-side and front-to-rear imbalance. A load biased to one side by more than 8% raises an alert on the shovel operator's screen, not just the truck's, which is where the behaviour that caused it actually lives.
Tanberg says two iron ore operations in Western Australia have run pre-production trucks for eight months. Commercial deliveries start mid-2027.
