Page 12: Functions
Functions The load is lifted, lowered or tensioned by operating the lever. The load pressure brake prevents automatic lowering of the load. NOTICE! If used "overhead" or "lashing" undefined forces may appear. We recommend to use a hoist with slipping clutch for these cases. NOTICE! The best protection against functional failures in case of extreme environmental impact is the regular use of the equipment. -
