Wire Rope

Wire rope is generally composed of wires, strands and core.

Wire rope varies:

• By Diameter

• The Grade of Steel

Wire rope may be manufactured from many grades and types of steel and alloys. Some of the more common grades are as follows:

IPS (1770 Grade)              – Improved Plow Steel

EIPS (1960 Grade)            – Extra Improved Plow Steel

EEIPS (2160 Grade)          – Extra Extra Improved Plow Steel

• Rope Lay

The “Lay” of the wire rope directly affects the operating properties.

The two most common types are:

1. Ordinary (or Regular) Lay

In Ordinary Lay wire rope, the direction of the wires is twisted in an opposite direction than the direction of the strands. Ordinary Lay may be Right Ordinary Lay or Left Ordinary Lay

Therefore,

Right Hand Ordinary Lay (or Right Hand Regular Lay) = RHOL (or RHRL) = Z Lay

Left Hand Ordinary Lay (or Left Hand Regular Lay) = LHOL (or LHRL) = S Lay

2. Lang Lay

In Lang Lay wire rope the direction of the wires are twisted in the same direction as the strands. Lang Lay may be Right Lang Lay or Left Lang Lay depending upon the direction of the strands.

The wires of an ordinary lay wire rope seem to travel parallel and along the length of the rope while those of a lang lay rope appear to travel around the rope.

• The Finish on The Wire

Most wire rope has an ungalvanised or galvanised finish. In addition, many wire ropes are stainless steel, or plastic/vinyl/urethane coated.

• The Core Material

The core is the central member about which the main strands are laid. Its main purpose is to provide support to the outer strands. Most wire ropes are supplied with either a fiber or steel core.

Fiber Cores – Natural Fiber Core or Synthetic Fiber Core (FC)

Steel cores – Independent Wire Rope Core (IWRC) or Wire Strand Core (WSC)

These steel cores provide more support than fiber cores to the outer strands. Steel cores resist crushing, are more resistant to heat, reduce the amount of stretch, and increase the strength of the rope.

 • Wire Rope Construction

There are hundreds of wire rope constructions; some of the more common arrangements are as follows:

Wire Rope	Construction	Application
6 x 19S IWRC		General Purpose Crane Duties Hoist Duties
6 x 25Fi IWRC		General Purpose Logging Crane Duties Hoist Duties
6 x 29Fi IWRC		General Purpose Lifting Crane Duties Hoist Duties
6 x 36(WS) IWRC		General Purpose Lifting Crane Duties Hoist Duties
18 x 7 WSC / 19 x 7		Crane Duties Hoist Duties
8 x 19		Elevator

WIRE ROPE SLING

Wire rope can be made into wire rope slings to meet the needs of any industry including Oil & Gas, Mining, Construction and Manufacturing. Numerous wire rope sling configurations can be made, such as single leg sling, multiple leg slings and a wide variety of end fittings.

There are different ways of securing the ends of wire ropes:

• Hand Splice
• Turnback Eye Mechanical Splice
• Flemish Eye Mechanical Splice
• Wire Rope Clamp
• Spelter Socket
• Swage Socket
• Stop End

How to order wire rope slings:

1. Define wire rope diameter / wire rope sling capacity
2. Define number of wire rope sling leg
3. Define wire rope end terminations
4. Define types of eyes (Thimbe Eye or Soft Eye)
5. Define any end fittings (Masterlink, Hook or Shackle)
6. Define the length of the wire rope sling

Soft Eye Turnback Mechanical Splice	Thimble Eye Turnback Mechanical Splice
Flemish Eye Mechanical Splice	Closed Swage Socket
Open Spelter Socket	Closed Spelter Socket

At PT. Supra Lifting Indonesia, we can manufacture wire rope slings by fitting and pressing the specific terminations according to customer’s special needs. Please contact us at (031) 561 8613 or email us at supra.liftindo@gmail.com

CAMLOK Container Lifting Lugs are supplied in sets of 4, serve as flexible lashing points for the transportation of containers.

There are two models available for the container lifting lug:

1. CLT – Vertically mounted at the top of the container
2. CLB – Horizontally mounted to the side of the container

CLT CAMLOK Container Lifting Lug

The CLT type is vertically mounted in the hole at the top of the container and is locked into place by simply turning the lug 90°. This configuration allows for transportation via the use of a spreader beam in conjunction with cables, chains or slings.

Model	Type of Lift	Top Angle between Slings	WLL set of 4 (ton)
CLT	TOP LIFT	VERTICAL	56
CLT-TOP LIFT-		VERTICAL – 56 -

CLB CAMLOK Container Lifting Lug

The CLB model is mounted horizontally to the side of the container at either the top or the bottom fixing holes. This model has a spring loaded bolt to prevent accidental release.

Model	Type of Lift	Top Angle between Slings	WLL set of 4 (ton)
CLB	SIDE LIFT	50 deg	32
CLB	SIDE LIFT	36 deg	40
SIDE LIFT – CLB CAMLOK Container Lifting Lug		CLB CAMLOK Container Lifting Lug

Webbing sling is sling belt manufactured from polyester that is normally used for heavy lifting under the circumstances where wire rope sling lifting or chain lifting are not applicable.

In comparison to wire rope/chain, webbing sling has got the following benefits:

• Lighter in weight
• Higher flexibility
• No corrosion
• Easier to inspect
• Smoother surface thus not damaging the surface of lifted products
• Cheaper at cost

Webbing sling applications include:

• Lifting heavy concrete pipe, big sized PVC or steel pipe
• Lifting cargo
• Lifting marble, glass and fragile products
• Lifting machine
• Safety latch for trucks, etc

At PT. Supra Lifting Indonesia, we sell and distribute polyester webbing sling under the brand name Superlift, manufactured in China.

POLYESTER FLAT WEBBING SLING

TYPES OF FLAT WEBBING SLING

There are several types of flat webbing sling, the most common use in the industries are:

• Double Eye & Eye (DEE)
• Single Endless (SES)

TYPES OF EYE

In the industry, Half Twist Eye is the most common used. Upon the customer request we can assemble the flat webbing sling with Flat Eye or Reversed Eye.

CAPACITY OF FLAT POLYESTER WEBBING SLING

 POLYESTER ROUND SLING

Round sling is polyester sling that is filled with twisted raw material yarn inside, thus resulting a round shaped sling. It is normally used to lift products that required softer approached.

CAPACITY OF POLYESTER ROUND SLING
