Nettet31. mar. 2024 · On most tower cranes, the limit switch is a geared mechanism attached to the hoist rope drum, which includes a deceleration limit and a final stop limit. In the two tower crane incidents, the hook block weighing around 400kg fell 50m and 100m respectively causing significant damage below. NettetTypically, the hoisting limit switch system on a tower crane includes a: deceleration function that slows the hoisting speed down; final limit switch that physically stops the hook two blocking. Both limiting functions prevent damage to the hoisting system and help prevent catastrophic failure of the hoist rope. Nettetpulled, the switching function of the pull-wire switch is activated. Hoist limit switches are used as signal emitters when the wire rope is relieved and must be pretensioned by something such as a weight. 2.4 Technical data Standards: IEC 60947-5-1 Enclosure: Thermoplastic Cover: Thermoplastic Protection class: IP67 to IEC 60529 coreldraw 2018 download link
