Power & Free Design
Power & Free conveyors are based on a twin-track system. The top track is used for the power chain and the bottom track for the carrier trolleys. On an equal pitch pusher dogs are fitted in the power chain and are used to pull the carriers around the system. The movable cams of the pusher dogs latch onto the trolley to form an interlink connection.
Stop stations are used to disengage the link between the power chain and trolleys. When a stop station is closed the carrier will stop while the power chain keeps moving. Because of the pusher dog and trolley design multiple carriers can buffer behind a stop station.
Advantages of a Power & Free Conveyor
- Compact design with movable parts inside the tack.
- Modular system with standard parts.
- Flexible design for optimal lay-out planning.
- Advanced automatic control system with touch screen user interface and remote access.
Components
Track sections are available as Power & Free, Free or only Power in standard or cut-to-length sections.
Bends can be horizontal or vertical. The radius of the bends is often standard. Non standard bend can be made on request.
The power chain comes in standard chain link pitches and can be fitted with open or closed bearings.
Depending on product dimensions and the conveyor lay-out the product carrier can have different trolley configurations. Using multiple trolleys the load capacity of carrier can be increased.
A Power & Free system needs a drive system. Depending on the type of Power & Free conveyor the drive mechanism can be a caterpillar drive or a helical-screw drive.
