    3 SAFETY PRINCIPLES 3.1 SAFETY SUMMARY Danger exists when lifting and travelling with loads, particularly when the chain block is not used properly or is poorly maintained. Since an accident or serious injury could result, special safety precautions apply to the operation with the chain block during its assembly, maintenance and inspection.

  • Page 5: When In Use

    3.2.2 When in use ALWAYS make sure the load is properly seated in the hook. ALWAYS make sure the safety latches of hooks work in the correct way. ALWAYS pay attention to the limit positions. ALWAYS use manual power only. ALWAYS when lifting loads approaching the nominal lifting capacity of the lifting device, we recommend, regarding the operating forces, the operation...

    ! WARNING The permissible maximum deflection of the trolley beam track from loading by own mass and nominal loading capacity is 1/500 of distance between suspending (supports). Permitted maximum gradient of running surface is 0,3%. Maximum height of the trolley beam track above the floor is 20m. An application of the chain block on higher trolley beam tracks is necessary to be consulted with the manufacturer.
