TH2-lifting clutch caliber

As with all lifting devices, the lifting clutch TH2 must also be checked at least twice a year by trained personnel. Any defects found should be corrected before use. It is important to determine the amount of wear. The lettering and identification of the lifting system must be visible. If the shackle is deformed or the mouth opening is enlarged, the clutch must be taken out of use and cannot be repaired. If the limiting dimensions given in the tables below are exceeded for “H” or fall below for “M” a further use of the clutch is not safe. Repairs, especially welding operations to the clutch itself are strictly forbidden. Do not combine our products with accessories from other manufacturers.
