Shaftlocking devices

Ameriloc wind-turbine shaft-locking devices provide secure shaft/ hub connections. The MLD (mechanical-locking devices) and HLD (hydraulic-locking devices) are custom engineered and manufactured for years of trouble-free service.

The HLD offers faster installation. With larger diameters, such as 20.8 in., the HLD can be tensioned within minutes, compared to the several hours needed for a mechanical-locking device. A hydraulic pump, required for assembly, can be a stationary unit, but a hydraulic hand pump can also be used for tensioning at difficult-to-reach places, such as the wind-turbine turret.

The MLD eliminates the need for keyways or splines, provides unlimited shaft positioning, and features zero backlash, reduced shaft stress, and high contact pressure for greater torque. It can fit into smaller installations and only requires standard tools to assemble.

Features include torque up to 4,425,372 lb-ft, outer diameters up to 57.1 in, and shaft diameters up to 29.5 in.
