Pertanyaan umum tentang LIFT-ALL dari 3G Electric.
What are the main differences between LIFT-ALL Type 4 and Type 5 web slings?
LIFT-ALL Type 4 web slings are twisted-eye slings with sewn eyes at each end, designed for use with hooks or shackles. They are available in single-ply or multi-ply constructions and are rated for vertical, choker, and basket hitches. Type 5 slings are endless (continuous loop) slings that can be used in a variety of hitch configurations, including vertical, choker, and basket, without the need for end fittings. Type 5 slings offer flexibility in rigging and are often used when the sling must be threaded around a load. Both types are available in polyester or nylon, with protected-edge options to extend service life.
What do the part numbers on LIFT-ALL web slings indicate?
LIFT-ALL part numbers follow a pattern that encodes sling type, material, ply count, width, and length. For example, in MPN EN1804TX18: 'EN' indicates endless (Type 5), '1' indicates 1 ply, '8' indicates 8,000 lb rated capacity (approximate), '04' indicates 4-inch width, 'T' indicates polyester, 'X' indicates protected edge, and '18' indicates 18-foot length. Similarly, 'EE' in a part number denotes twisted-eye (Type 4). The exact coding may vary by series, but the tag on each sling provides the rated capacity and working load limits for all hitch configurations.
Can LIFT-ALL polyester web slings be used in outdoor or wet environments?
Yes, LIFT-ALL polyester web slings are suitable for outdoor use because polyester resists UV degradation and moisture absorption better than nylon. Polyester slings maintain their strength when wet and are less affected by sunlight exposure over time. However, all slings should be inspected before each use for cuts, abrasion, UV damage, or chemical exposure. For environments with strong acids or alkalis, consult the sling's chemical resistance data. Nylon slings, while stronger per unit weight, lose strength when wet and are more susceptible to UV damage.
What is the working load limit (WLL) of a LIFT-ALL Type 4 sling with a 6,400 lb vertical hitch capacity?
The 6,400 lb figure is the rated vertical hitch capacity for that specific sling (e.g., MPN EE2802DTX6). In a choker hitch, the capacity is reduced to 80% of the vertical rating (5,120 lb), and in a basket hitch, the capacity is 200% of the vertical rating (12,800 lb), provided the sling is not twisted and the load is evenly distributed. Always refer to the tag on the sling for exact ratings, as capacities vary by sling type, material, ply count, and configuration. LIFT-ALL slings are designed with a 5:1 design factor.
How should LIFT-ALL web slings be stored and inspected?
LIFT-ALL web slings should be stored in a clean, dry, and cool environment away from direct sunlight, UV sources, and chemicals. They should be hung on racks or pegs to avoid kinking or crushing. Before each use, inspect the entire sling for cuts, fraying, abrasion, broken stitching, heat damage, chemical attack, or distortion of the tag. If any damage is found, remove the sling from service immediately. Slings should also be inspected annually by a qualified person per ASME B30.9 standards. Records of inspection should be maintained.
