Here’s the loader demonstrating a logging device. Weight for this rig is quoted at 1,700 kg, suggesting it’s been built strongly–as if this photo isn’t enough evidence of the same. All machines appear to be controlled with conventional, off-the-shelf twin stick controllers.
The man in the middle of this photo seems to be the builder and seller. Weighing 2,300 kg, the dumper’s load capacity is estimated to be a hugely impressive 4,000 kg or nearly 9,000 pounds! Tires look accurate and must have been custom made.
