The 871 Series delivers continuous torque capacity up to 670 lb-ft (908 N-m) with no derating required for continuous-duty use. Nine speed ratios and thirteen output options give installers wide flexibility across fire and rescue, refuse, truck crane, and pumper-cleaner vocations. The compact housing reduces clearance concerns compared to larger-footprint units. This series replaces the Chelsea 870 Series and carries over all three of Chelsea's premium options: Wet Spline, SmartStart, and Quiet Gear.
