In addition to a wide selection of force transducers and load cells, WIKA of course also offers force measuring instruments. The FRKPS series chain hoist test set provides a force measuring instrument with which the friction clutches on chain hoists can be checked. These checks are carried out at regular intervals in operations using chain hoists. With the mobile FRKPS, this regular check is particularly easy because the instrument is extremely easy to handle. The chain hoist test set consists of a hand-held indicator, several centring sleeves and adapters, a charger and the signal cable. As the set includes a number of common adapters for the most frequently used types of chain, including section steel chains, the FRKPS is suitable for almost all industrial chain hoist testing applications. Because it is delivered in a handy aluminium case, all components are stored in an orderly fashion and quick and simple utilisation is thus ensured. The handling is very simple. At the chain of the hoist, the force transducer is pulled up to the chain hoist stop and blocked there. Then the resulting force is measured to test the maximum force at which the friction clutch is triggered. Based on a comparison with the permissible values, compliance with the limit values is checked. With an accuracy of approx. 1 kg, the FRKPS can be used for measuring ranges of 40 kg up to 3,500 kg.
