Demag load detectors |
Increased safety for supporting structures by means of overload protective device
All DRPRO wire rope hoists are equiped with standard overload protection, but this optional load detector is used for more accurate display
Efficient production requires all hoists to be working to capacity. However, it is sometimes difficult to estimate loads. The Demag load detector provides effective protection for supporting structures and hoist units against overload - and satisifes the overload protection requirement laid down according to the EC Machinery Directive. The Demag load detector offers protection for all Demag and also third-party hoist units, for open winch crabs and the entire load range, also for arduous applications.
Mechanical load detection
MGS load link with mechanical micro-switches and MKA-2 electronic evaluator for overload protection and overload cut-off. Maximum switching point deviation ± 2.5 %, with reference to 2 x 106 load cycles.
Load spectrum recorder
Relevant legislation in many countries stipulates that the remaining safe working period (SWP) has to be determined. WLK-1 or FWL load spectrum recorders make it easy to calculate the remaining service life accurately.
Electronic load detection
Carrier link with strain gauge bridge, FGB frequency generator and FAW-1 frequency evaluator for overload protection and overload cut-off. The electronics provide setpoint load limitation, summation measurement and hoist motor cut-off in the case of slack rope.
Load display unit
An optional feature is a digital load display which can be used for assessing the approximate handling rate of an installation. Three-figure digital display, with a choice between type ANZ-1 in the DST control pendant, type ANK-1 in the driver’s cab, or ANG-1 large format display (character height 120 mm).
