Abstract
A drum spooling system with a line protective material or wrap that can be wound and unwound with a load-bearing line, such as a wire rope, on a load drum to form a superposed arrangement of layers of the load-bearing line and protective material around the load drum, which advantageously reduces the pressure on the drum, radial space and/or drum size requirements, and damage to the wire rope resulting from the spooling and unspooling process, among other things.
Claims7
A drum spooling system, comprising:
- a) a load drum mounted for rotational motion, the load drum being operatively associated with a motor for driving rotational motion thereof;
- b) a storage drum mounted for rotational motion;
- c) a load-bearing line having a first end engaged with the load drum, a second end attached to a load, and an intermediate section, the intermediate section being alternately spooled on the load drum and unspooled from the load drum responsive to alternating rotational motion of the load drum;
- and
- d) an protective wrap having a longitudinal groove defined therein, the protective wrap having a first end engaged with the storage drum, a second end engaged with the load drum, a first intermediate portion and a second intermediate portion, wherein responsive to alternating rotational motion of the load drum, the first intermediate portion is alternately spooled on the storage drum and unspooled from storage drum and the second intermediate portion is alternately spooled on the load drum and unspooled from the load drum simultaneously with the intermediate section being alternately spooled on the load drum and unspooled from the load drum,
- wherein the intermediate section of the load-bearing line is received in the longitudinal groove of the second intermediate portion responsive to the spooling of the intermediate section of the load-bearing line on the load drum.
