SERVICE hook must entirely support the load; latch must not support the load NEVER side or back load a hook NEVER tip load a hook when using two slings make sure that the angle from the vertical is not greater than 45° always check before the use, that the hook can support the load; never lift a load greater than the working load limit; lift the load without shocks hook exposure to temperature greater than 200-250°C affect mechanical performances; in this case is better consider a WLL reduction from 20% to 40% depending on the temperature reached. In any case don't exceed 400 °C NEVER repair, modify, weld or heat a hook
COLD TEMPERATURE SERVICE (BELOW -40°C) these hooks must be ordered with certified impact properties and certified magnetic test performed by the manufacturer hooks with surface defects must not be used until these are removed by grinding (remember that the maximum reduction allowed is 5% of the original cross section) hooks that have been welded or modified must not be used all the hooks should undergo a periodic surface inspection using either visual and magnetic test all liftings should be performed at a slow rate; any shock should be avoided; don't change the speed all the hooks should be given a visual inspection before each lift
INSPECTIONS at least every 3 months, or even more frequently when the accessory is used in severe conditions, a visual inspection is recommended to detect deformations, surface defects or anything else that could affect hook performances hooks used in frequent and stressing operative conditions must be regularly inspected taking care of: thread: damaged thread cause loss of load opening: must not be greater than 10% of nominal value worn areas: in correspondence of contact with slings and of maximum strength area distortions every year, or even more frequently when the accessory has been used in severe conditions, perform a magnetic test or a non destructive test at 1,5 times the WLL make sure that the dimensions 2 and 3 are not altered significantly (more than 5% of the original dimension) hooks must be removed from service when the standards are not respected record all the inspections
MAINTENANCE Swivel without bearing At least every three months perform following operations: clean carefully contact area between swivel basket and hook' shank and lubricate inside with slightly clammy oil; rotate the swivel or hook in order to spread the oil on the hook shank Oil the contact area between nut and swivel basket
Swivel hooks with bearing At least every three months perform following operations: clean carefully contact area between swivel basket and hook' shank and lubricate inside with slightly clammy oil; rotate the swivel or the hook in order to spread the oil on the hook shank spread grease along the perimeter of the thrust washer Oil the contact area between nut and swivel basket
