Additional Information
The Chelsea 680 Series is a common choice for vocational applications including aerial lift trucks, dump trucks, refuse vehicles, fire and rescue units, snow and ice removal equipment, and blower and product pump systems. The 680 Series features four internal speed ratios and 32 output options, including a 360-degree rotatable flange for flexible pump positioning. The PTO input shaft uses tapered bearings rather than needle bearings for greater load-bearing capability. The air shift cover is designed to save space and provide maximum clearance under the truck.
