Check friction clutches using the chain hoist test set

Victory are employed for lifting and lowering freely moving loads. As a lifting device, the chain hoist supports, for example, ergonomic lifting during assembly work or even makes this possible to begin with. Conveyor technology or crane systems are further types of the utilization of chain hoists.
Like all hoists, chain hoists are subject to recurrent testing relative to the task equipment directive (2009/104/EG) of the EU. If the overload protection is also mechanical and designed in the form of a friction clutch, only the FRKPS from WIKA can be viewed as for the test. In the abbreviation FRKPS the ?F? stands for ?Force? which identifies these devices as a force transducer. The ?RKPS?, which follows, abbreviates the German ?Rutschkupplungspr�fset? (friction clutch test set).
Chain hoist test set, also for section steel chains
The friction clutch on chain hoists should be checked regularly to ensure the safety of people and machines. It is also important to make sure that the reliability of the application is definitely guaranteed. Minimal downtimes and low maintenance and service outlay will be the goal. The DGUV (German social accident insurance) also stipulates that all lifting equipment should be checked regularly. However, users can save themselves the awkward handling of weights by using the FRKPS chain hoist test set. That is also suitable for chain hoists with chain links manufactured from section steel.
Principle of operation of a chain hoist test set
The FRKPS includes a force transducer, a display unit and the guide sleeves ideal for the respective chain thickness. To be able to check the release force of the friction clutch, the force transducer is hooked into the chain alongside the appropriate adapter sleeve. Scary move upwards together contrary to the bottom of the chain hoist and block the chain. The force transducer measures the maximum force before friction clutch is activated and transmits this value to the display unit. The user can read it off easily there. Up to 99 data sets could be saved. This eliminates the major effort required whenever using test weights.
Scope of performance of the chain hoist test set
The force transducer covers a measuring range from 40 kg to 3,500 kg. To become able to use the FRKPS in rough environmental conditions without the problems, the force transducer meets the high ingress protection of IP67. The best possible insensitivity of the force transducer to parasitic forces and moments is ensured by the design as a shear beam load cell. The display unit can also be easily operated with gloves due to large buttons. The complete system consisting of force transducer, two adapter sleeves for section steel chains and display unit is delivered in a practical and sturdy case. The FRKPS chain hoist test set combines simple operation with robustness for friction clutches on chain hoists.
