Parker Hannifin has introduced the Chelsea 522 heavy duty air shift PTO. This delivers performance and reliability from a compact unit, is available for all major truck transmissions, and is suited to pulling, pushing or lifting applications.
Designed with safety and ease of use in mind, the simple to install 522 has an internal shift mechanism to minimise transmission misuse, while the use of a gasket eliminates gear backlash to check or set and the need to adjust gaskets; these features are combined with an integrated electric switch enabling the operator to confirm when the PTO is fully engaged. The unit is rear mounted, and being compact in size gives good clearance in comparison to other heavy duty PTO’s; in addition, to increase the life of the hydraulic pump, the unit has independent shaft support bearings.
The unit is available in two shift types, air, or electric over air, with 1-1/4” tapered or parallel shaft, with ratio’s of 1:1.35 and 1:1.75.
