Ameridrives - Model HLD - Hydraulic Shaft Locking Devices
From Wind Turbine Locking Devices
Ameriloc hydraulic (HLD) and mechanical (MLD) locking devices are custom engineered for a lightweight,high torque connection between the turbine main shaft and gearbox. Units are domestically manufactured to provide years of trouble-free service in wind turbines rated up to 3 MW. The greatest advantage of the Ameriloc HLD (Hydraulic Locking Devices) is the significant time savings during installation. With larger diameters,such as 20.8 in. (530 mm),the HLD can be tensioned within only a few minutes, compared to several hours required for a mechanical locking device. The hydraulic pump required for assembly can be a stationary unit,but the use of a hydraulic hand pump is also possible for tensioning at difficult-to-reach places such as the turret of a wind turbine.
