Speed Controllers - Brake

Commonly referred to as pallet brakes, Ensalco speed controllers operate similar to automotive shoe type brakes. Centrifugal forces generated by the outer brake hub cause internal gearing to force the brake pads against the inner surface of the brake hub. Faster rotation increases the braking action. Ensalco speed controllers can be easily mounted for direct or indirect braking.

The function of a Ensalco speed controller is exactly as the name indicates... to control the speed of pallets, totes and cartons, while guiding and maintaining flowability on gravity conveyor tracks. This controlled speed of flow is achieved by planetary gearing, which at every revolution presses the centrifugal brake disks against the roller body, raising it's braking force proportionally to the speed of rotation. This self-energized device requires no external power source. Speed Controller spacing is generally one pallet position apart, although ideal spacing is best determined by testing of actual pallet and load. Correct placement of the speed controllers and the proper model selection are influenced by several factors.


Environments, such as wet conditions, cold or heat Slope or pitch of the conveyor rails
Construction and capacity of the conveyor rails Resistance of the speed controller
Characteristics of the goods being conveyed (size, shape, etc.)

Speed controllers are easily installed in either a "direct" or "indirect" method, as illustrated below. In a direct braking configuration, the speed controller has immediate contact with the load.

Indirect braking is preferred in many cases as the speed controller is mounted underneath the conveyor rollers and does not make direct contact with the load.
