When referring to adjusting a spring hanger, first you must define whether or not your are talking about a length adjustment or a load adjustment. When modifying the length of a spring support, you would utilize its load column to change its original length position. When adjusting the load of a variable spring hanger, you would remove the travel stops and then alter the load by modifying the position of the load column. When adjusting the load of a constant spring hanger, you would adjust the load by changing the initial compression seen at the spring coil.
