Rotating tops are available with a number of braking options to choose from.
A manually operated locking shaft mechanically locks the rotating platform in 90-degree increments and is manually retracted to release the lock when rotation is to resume.
A spring loaded rotator lock works on the same basic principle as above. The spring loaded shaft automatically engages and locks the rotator and is manually retracted to release the lock when rotation is to resume.
Spring activated detents are available to stop the rotation at every 90 degrees or 180 degrees. As the top rotates the spring loaded ball transfers “slip” into position and the rotating top is now held in position (note that the rotating top is not locked into position with this option); a slight manual effort is required to push the rotating top past the detent and to continue with the rotation.
A rotator brake is a friction style brake that pushes upward and contacts the underside of the rotating top. The operator positions the rotating top and then turns the activating grip handle clockwise applying the brake to the underside of the rotator holding the rotating top in position. The benefit of this arrangement is that it is not subject to damage if a fork lift impacts the rotating top while loading or unloading the lift.
