Yes, but only for a very short period, otherwise damage may occur and reduce the life of the shaker components. For the best results, you should always stay around the 80% rated capacity. This is the same for all shakers on the market.
In addition to this, we would state that you should size the shaker to be above this rating to prevent issues caused by measurement errors, dynamic responses, control position tolerances and overall calculation errors of practice vs theory. 100% is achieved at the factory under strict conditions but we do not expect our customers to try this. The maximum values are there as a performance guide of a perfect setup to provide limits for the 80% calculation. There is typically a 10% overall uncertainty of measurement, which means that 90% limitations are already restricting the actual measured capability.
