Ameridrives Couplings now offers mechanical & hydraulic shaft locking devices which are custom engineered and manufactured at our Erie, PA facility. Ameriloc locking devices are highly engineered to provide years of trouble-free service.
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.
The MLD (Mechanical Locking Device) units eliminate the need for keyways or splines, provide unlimited shaft positioning, and feature zero backlash, reduced shaft stress, and high contact pressure for greater torque. The MLD series has the ability to fit into smaller installations while only requiring standard tools to assemble.
All units are pre-assembled, ready to install. Torque range up to 4,425,372 ft.lbs. (6,000 kNm). A wide range of possibilities is available with outer diameters up to 57.1 in (1,450 mm), and shaft diameters up to 29.5 in. (750 mm).
