Brake Size This must be selected to give required braking torque and also be suitable to dissipate heat generated during braking operations without over heating. Brake Torque This is often negated to drive motor torque by an arbitrary service factor, typically 100% full load torque for crane travel and similar inertial loads which tend to be self-stopping or 150% for crane hoist and other overhauling loads. Continuous Rating Coils operate at class 'B' temperature while contiguously energized. Intermittent Rating Short time rated for up to 120 operations per hour max. 5 min. in 15 min. (33% on). Flameproof Magnet (Hazardous Locations) Some magnet sizes available with flameproof enclosures (Type AF) to BS229 for Group I,II, & III. Allow +40% weight for AF type, please contact us. |
