The big advantage for Ameriloc HLD (Hydraulic Locking Devices) is the short time it takes to install. With larger diameters, 530 mm, the HLD can be tensioned in a few minutes, compared to several hours required for another similar design. The hydraulic pump required for assembly can be a stationary unit, but use of a hydraulic hand pump is also possible for tensioning at difficult-to-reach places, such as the turret of a wind turbine. Torques range to 5,835 kNm. A wide range of possibilities is available with outer diameters up to 1,450 mm, and shaft diameters up to 750 mm. The mechanical locking device is shown.
