Renold has developed a chain for motor graders that allows the transmission of 30% more power without increasing the size.
According to Chris Lodge, Renold Chain’s engineering manager, this was achieved by varying the relative sizes of pins, inner plates, bushes and roller.
“There was some new materials technology in there as well,” he explained.
The customer was a “major manufacturer of earth moving vehicles and equipment”, which wanted a chain for a new range of motor graders, that were to be 30 per cent more powerful than their predecessors without a change of chassis.
The new chain has since been tested on motor graders that follow dumper trucks on track roads as they leave and return to a quarry near the arctic circle in order to undo the damage done by the trucks.
