Model 76 Control Stand - Imperial

Model 76 Control Stand - Imperial


    Econoline fixed center drives utilize the same type of spring-loaded pulley as an adjustable center drive, only it is normally mounted on the driven shaft. The driver pulley is of similar size and construction, but it is manually adjustable. A fixed center drive offers greater driven speed range in a more compact space. There are two types of controllable pulleys: the M type with a hand wheel and built-in adjusting device, and the MLA type that uses an external control. The MLA type pulley can be used with the Lovejoy #76 Control Stand or some other type of linear controller.
Motorized Torque Arm - Imperial

Motorized Torque Arm - Imperial


    A motorized control feature is available for all three drive packages, making it possible to convert from the standard handwheel to convenient remote control. This option consists of a servo motor that opens and closes the driver pulley flanges from a separate control station, allowing accurate speed adjustment in locations that may be inconvenient, remote or hazardous. Conversion is easy, requiring only the removal of the hand wheel and torque rod from the standard manual pulley, installing the motorized torque arm in place of the hand wheel, and connecting the CN2601 control switch to the servo motor and power source.
501 Torque Arm Bracket - Imperial-2

501 Torque Arm Bracket - Imperial


    Fixed center drive assemblies require a torque arm bracket to prevent the hand wheel from spinning. This allows speed to be changed while the drive is running. This bracket may be used with Econoline, WB, Hi-Ratio, and Hexadrive Fixed Center Drives. Bracket is NOT needed with the MLA type pulley.
