2011 volvo introduced a new wheel loader class

I think there may be some confusion here!

Volvo Construction Equipment (VCE) did introduce a new wheel loader class in 2011, but it was not a completely new class. Instead, it was an expansion of their existing wheel loader range.

In 2011, Volvo introduced the L150H and L180H wheel loaders, which were part of their H-series range. These machines were designed to offer improved performance, efficiency, and operator comfort. The L150H was a 15-tonne machine, while the L180H was an 18-tonne machine.

The H-series wheel loaders were designed to provide high productivity, low operating costs, and excellent fuel efficiency. They featured advanced technology, such as Volvo's patented Load Margin Control system, which helps to optimize load capacity and reduce the risk of overloading.

So, while Volvo did introduce new wheel loaders in 2011, it was not a completely new class, but rather an expansion of their existing range.
