strand jacking
 n.— «What is impressive about strand-jacking is its simplicity. It requires two gantries to be constructed either side of the object to be lifted.—A cross beam was mounted on top of the gantries and, after this, the lifting cables were fed through two apertures in the cross-beam. Mounted on top of the cross-beam were two strand jacks. These hydraulic lifting devices are rather like the hydraulic jacks that most people have in the boot of their car.» —“Record Lift” by Andrew Lanham Mining Weekly (Garden View, South Africa) Sept. 30, 2005.
