Thread lifting loops is a lifting device for lifting anchors, such as reinforcement anchors, wave anchors, and lifting sleeves. They are economical lifting loops and applicable for a lot purposes, especially construction or operation sites. They are not suitable for turning or position. Labels of loops are marked with the related

Special custom design grabs, hooks, clamps, or other lifting accessories, for such units as modular panels, prefabricated structures and similar materials, shall be marked to indicate the safe working loads and shall be proof-tested prior to use to 125 percent of their rated load.

Scope. This section applies to slings used in conjunction with other material handling equipment for the movement of material by hoisting, in employments covered by this part. The types of slings covered are those made from alloy steel chain, wire rope, metal mesh, natural or synthetic fiber rope (conventional three strand construction), and synthetic web (nylon, polyester, and polypropylene).

Employers must not use improved plow-steel wire rope and wire-rope slings with loads in excess of the rated capacities (i.e., working load limits) indicated on the sling by permanently affixed and legible identification markings prescribed by the manufacturer.

An eye splice made in any wire rope shall have not less than three full tucks. However, this requirement shall not operate to preclude the use of another form of splice or connection which can be shown to be as efficient and which is not otherwise prohibited.

Except for eye splices in the ends of wires and for endless rope slings, each wire rope used in hoisting or lowering, or in pulling loads, shall consist of one continuous piece without knot or splice.

Wire rope shall not be used if, in any length of eight diameters, the total number of visible broken wires exceeds 10 percent of the total number of wires, or if the rope shows other signs of excessive wear, corrosion, or defect.

Cable laid and 6 × 19 and 6 × 37 slings shall have a minimum clear length of wire rope 10 times the component rope diameter between splices, sleeves or end fittings.

Safe operating temperatures. Fiber core wire rope slings of all grades shall be permanently removed from service if they are exposed to temperatures in excess of 200 °F (93.33 °C). When nonfiber core wire rope slings of any grade are used at temperatures above 400 °F (204.44 °C) or below minus 60 °F (15.55 °C), recommendations of the sling manufacturer regarding use at that temperature shall be followed.

Wire rope slings shall have permanently affixed, legible identification markings stating size, rated capacity for the type(s) of hitch(es) used and the angle upon which it is based, and the number of legs if more than one.

Employers must not use natural- and synthetic-fiber rope slings with loads in excess of the rated capacities (i.e., working load limits) indicated on the sling by permanently affixed and legible identification markings prescribed by the manufacturer.

In manila rope, eye splices shall contain at least three full tucks, and short splices shall contain at least six full tucks (three on each side of the centerline of the splice).

In layed synthetic fiber rope, eye splices shall contain at least four full tucks, and short splices shall contain at least eight full tucks (four on each side of the centerline of the splice).

Strand end tails shall not be trimmed short (flush with the surface of the rope) immediately adjacent to the full tucks. This precaution applies to both eye and short splices and all types of fiber rope. For fiber ropes under 1-inch diameter, the tails shall project at least six rope diameters beyond the last full tuck. For fiber ropes 1-inch diameter and larger, the tails shall project at least 6 inches beyond the last full tuck. In applications where the projecting tails may be objectionable, the tails shall be tapered and spliced into the body of the rope using at least two additional tucks (which will require a tail length of approximately six rope diameters beyond the last full tuck).

Safe operating temperatures. Natural and synthetic fiber rope slings, except for wet frozen slings, may be used in a temperature range from minus 20 °F (-28.88 °C) to plus 180 °F (82.2 °C) without decreasing the working load limit. For operations outside this temperature range and for wet frozen slings, the sling manufacturer"s recommendations shall be followed.

Splicing. Spliced fiber rope slings shall not be used unless they have been spliced in accordance with the following minimum requirements and in accordance with any additional recommendations of the manufacturer:

In manila rope, eye splices shall consist of at least three full tucks, and short splices shall consist of at least six full tucks, three on each side of the splice center line.

In synthetic fiber rope, eye splices shall consist of at least four full tucks, and short splices shall consist of at least eight full tucks, four on each side of the center line.

Strand end tails shall not be trimmed flush with the surface of the rope immediately adjacent to the full tucks. This applies to all types of fiber rope and both eye and short splices. For fiber rope under 1 inch (2.54 cm) in diameter, the tail shall project at least six rope diameters beyond the last full tuck. For fiber rope 1 inch (2.54 cm) in diameter and larger, the tail shall project at least 6 inches (15.24 cm) beyond the last full tuck. Where a projecting tail interferes with the use of the sling, the tail shall be tapered and spliced into the body of the rope using at least two additional tucks (which will require a tail length of approximately six rope diameters beyond the last full tuck).

Removal from service. Natural and synthetic fiber rope slings shall be immediately removed from service if any of the following conditions are present:

Employers must use natural- and synthetic-fiber rope slings that have permanently affixed and legible identification markings that state the rated capacity for the type(s) of hitch(es) used and the angle upon which it is based, type of fiber material, and the number of legs if more than one.

The Wire Rope Lifting System is an economical lifting loop for utility type structures. It is used in either face or edge lifts applications and is "mucked" into the surface of the concrete. The galvanized wire rope is formed in a figure-8 shape, with the ends of the rope secured by a positive swaged clamp, and a steel band at approximately the midpoint to establish the proper shape. The Wire Rope Lifting System is embedded 2/3 of its length into the concrete. The hardware must be standard hook or clevis with a diameter at least twice the rope diameter. Each anchor has a color-coded tag which identifies the SWL in tension of the anchor.

American Step Wire Rope Loop Lifters will meet listed load rating values only when properly installed by the concrete structure manufacturer in properly reinforced structures and per the minimum embedment depth listed.

Pulling / Lifting IronsAmerican Step Pulling/Lifting Irons have many uses for lifting or as pulling anchor points when properly installed in steel reinforced concrete structures. They are manufactured at our facility in Griffin, Georgia of 1/2 inch steel cable meeting ASTM A 416, 7 Wire, 270 Grade.

American Step Pulling/Lifting Irons meet the following values only when properly installed by the concrete structure manufacturer. The 2 haunches of the pulling/lifting iron must be securely tied under the reinforcement of the structure and placed at the minimum required embedment depth as listed. The following load ratings are set in accordance With OSHA 1926.704 (c) which requires a safety factor of four to one.

Use in non-reinforced concrete can cause tensile failure of the concrete above the haunches of the pulling/lifting iron and is specifically not recommended. Improper installation can result in serious injury or death.

American Step Company pioneered the patented solid loop lifters. This lifter is used in the same manner as the wire rope loop lifter. One simply floats the lifter into the concrete to the required depth. All load ratings are based upon no steel reinforcement except for the ¾” and the one inch sizes. The advantages of the solid loop lifters over the wire rope loop lifters, whether ours or another company’s, are reduced corrosion potential due to the solid steel instead of numerous small wires and that the lifters are powder epoxy coated per ASTM A 934 which we believe is a better means to protect against corrosion than by galvanizing. We have solid loop lifters load rated from 4,000 pounds to 18,750 pounds in 4,000 PSI concrete.

The solid loop lifters are made of domestic USA steel and the parts are made and coated in the American Step manufacturing facility located in state of Georgia, USA.

The American Step utility anchors are available with wire clips for attaching to the cage reinforcement. We can custom fabricate the wire clips and their location on the lifter to fit your individual needs, and since we do it here in Georgia USA, we do not have to wait for months on the ship to arrive from China.

Wire rope clips are widely used for making end terminations. Clips are available in two basic designs; the U-Bolt and fist grip. The efficiency of both types is the same.

When using U-Bolt clips, extreme care must be exercised to make certain that they are attached correctly; Incorrect installation can reduce the working load limit by 40%. Below are general guidelines for installing wire rope clips.

The saddle shall be placed on the live end of the wire rope, with the U-bolt on the dead-end side—Remember the well-known saying: “Never saddle a dead horse.” Use at least two or three wire rope clips to secure the ends properly to the length of the rope, and tighten nuts evenly one by one until reaching the recommended torque.

Step 1. Turn back a specified amount of rope from the thimble or loop. The first clip must be placed one bridge width from the turned back rope tailor dead end of the rope, Apply U-Bolt over dead end of wire rope – live end rests in the saddle (Never saddle a dead horse!) Tighten nuts evenly, alternate from one nut to the other until reaching the recommended torque.

Step 2. When more than two clips are required, apply the second clip as near the loop or thimble as possible, tighten the nuts firmly but not yet to the specified torque.

Step 3. When three or more clips are required, space additional clips equally between the first two – take up rope slack – tighten nuts on each U-Bolt evenly, alternating from one nut to the other until reaching recommended torque.

In accordance with good rigging and maintenance practices, the wire rope end termination should be inspected periodically for wear, abuse, and general adequacy. Periodically re-tightening of the nuts must be done at 10.000 cycles (heavy usage), 20.000 e.g. every 3 months, 6 months, annually.

Malleable clips are to be used for making eye termination assemblies only with the right regular lay wire rope and only for light-duty uses with small applied loads, such as handrails, fencing, guard rails, etc.
