Hoisting technology and cranes without downtime

[] Kran- und Hebetechnik

Many cranes and lifting equipment are forced to shut down if there is a problem with the power supply. Upcoming electrical problems are recognised early using Bender ISOMETER®s and/or fault current monitoring devices, enabling prompt error localisation and repairing. This avoids sudden shutdowns.
