She insisted on working alone, using a hydraulic lift, which she pushed from spot to spot.
With that, the street sweeper used a hydraulic lift to tilt its hopper full of trash into a dump truck.
Strength was measured by using a hydraulic Jamar gauge.
Handgrip strength was also measured by using a hydraulic hand dynamometer (Sammons JAMAR 7498-05 Handaulic HanDynamometerer; Sammons Preston Rolyan, Chicago, IL, USA).
For this reason, as binders alternatively a blended cement and a hydraulic lime were used, both proving to be unsensitive to sulphates.
Grip strength of the dominant hand was measured using an hydraulic dynamometer (Jamar Hydraulic Hand Dynamometer Model J00105, Lafayette Instrument Company, Inc., IN, USA).
Portland cement is a successor to a hydraulic lime that was first developed by John Smeaton in 1756 when he was called in to erect the Eddystone Lighthouse off the coast of Plymouth, Devon, England.
While planning the lighthouse, he discovered the best mortar for underwater construction to be limestone with a high proportion of clay, and thus he was the first to recognize what constitutes a hydraulic lime.
The latter, combined with the absence of alite and other silicates, indicates that this is a hydraulic lime with no additions of cement (Figure 3b).
These days, he uses a hydraulic Murphy bed of his own design, hidden behind a sofa during the day.
