Check friction clutches utilizing the chain hoist test set

Chain hoists are used for lifting and lowering freely moving loads. As a lifting device, the chain hoist supports, for instance, ergonomic lifting during assembly work and even makes this possible to begin with. Conveyor technology or crane systems are further examples of the usage of chain hoists.
Like all hoists, chain hoists are at the mercy of recurrent testing in accordance with the work equipment directive (2009/104/EG) of the EU. If the overload protection is also mechanical and designed by means 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).
ไดอะแฟรม hoist test set, also for section steel chains
The friction clutch on chain hoists should be checked regularly to guarantee the safety of individuals and machines. It is also important to ensure that the reliability of the application is always 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 must be checked regularly. However, users can save themselves the awkward handling of weights utilizing 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 consists of a force transducer, a display unit and the guide sleeves suitable for the respective chain thickness. So that you can check the release force of the friction clutch, the force transducer is hooked in to the chain alongside the appropriate adapter sleeve. They 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. ไดอะแฟรม ซีล can read it off easily there. Around 99 data sets could be saved. This eliminates the major effort required when working with 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 utilize the FRKPS in rough environmental conditions without the problems, the force transducer meets the high ingress protection of IP67. ไดอะแฟรม of the force transducer to parasitic forces and moments is ensured by the look as a shear beam load cell. The display unit may also be easily operated with gloves because of large buttons. The entire system comprising 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.
