Check friction clutches using 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 types of the use of chain hoists.
Like all hoists, chain hoists are subject to recurrent testing relative to the work equipment directive (2009/104/EG) of the EU. If the overload protection can be mechanical and designed by means of a friction clutch, only the FRKPS from WIKA can be considered for the test. In the abbreviation FRKPS the ?F? means ?Force? which identifies the device as a force transducer. The ?RKPS?, which follows, abbreviates the German ?Rutschkupplungspr�fset? ( Behind The Scenes ).
Chain 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. Additionally it is important to ensure that the reliability of the application is definitely guaranteed. Minimal downtimes and low maintenance and service outlay will be the goal. Launch (German social accident insurance) also stipulates that lifting equipment should be checked regularly. However, users can save themselves the awkward handling of weights by using the FRKPS chain hoist test set. This is also suitable for chain hoists with chain links made of 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. So that Up-sell 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 against the bottom of the chain hoist and block the chain. The force transducer measures the utmost force before friction clutch is activated and transmits this value to the display unit. The user can read it off easily there. Around 99 data sets can 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 between 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. 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 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.
