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.
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.
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.
