non rotating wire rope specifications made in china

Original equipment wire rope and replacement wire rope must be selected and installed in accordance with the requirements of this section. Selection of replacement wire rope must be in accordance with the recommendations of the wire rope manufacturer, the equipment manufacturer, or a qualified person.

Wire rope design criteria: Wire rope (other than rotation resistant rope) must comply with either Option (1) or Option (2) of this section, as follows:

Option (1). Wire rope must comply with section 5-1.7.1 of ASME B30.5-2004 (incorporated by reference, see § 1926.6) except that section"s paragraph (c) must not apply.

Option (2). Wire rope must be designed to have, in relation to the equipment"s rated capacity, a sufficient minimum breaking force and design factor so that compliance with the applicable inspection provisions in § 1926.1413 will be an effective means of preventing sudden rope failure.

Type I rotation resistant wire rope ("Type I"). Type I rotation resistant rope is stranded rope constructed to have little or no tendency to rotate or, if guided, transmits little or no torque. It has at least 15 outer strands and comprises an assembly of at least three layers of strands laid helically over a center in two operations. The direction of lay of the outer strands is opposite to that of the underlying layer.

Type II rotation resistant wire rope ("Type II"). Type II rotation resistant rope is stranded rope constructed to have significant resistance to rotation. It has at least 10 outer strands and comprises an assembly of two or more layers of strands laid helically over a center in two or three operations. The direction of lay of the outer strands is opposite to that of the underlying layer.

Type III rotation resistant wire rope ("Type III"). Type III rotation resistant rope is stranded rope constructed to have limited resistance to rotation. It has no more than nine outer strands, and comprises an assembly of two layers of strands laid helically over a center in two operations. The direction of lay of the outer strands is opposite to that of the underlying layer.

Type I must have an operating design factor of no less than 5, except where the wire rope manufacturer and the equipment manufacturer approves the design factor, in writing.

When Types II and III with an operating design factor of less than 5 are used (for non-duty cycle, non-repetitive lifts), the following requirements must be met for each lifting operation:

A qualified person must inspect the rope in accordance with § 1926.1413(a). The rope must be used only if the qualified person determines that there are no deficiencies constituting a hazard. In making this determination, more than one broken wire in any one rope lay must be considered a hazard.

Each lift made under § 1926.1414(e)(3) must be recorded in the monthly and annual inspection documents. Such prior uses must be considered by the qualified person in determining whether to use the rope again.

Rotation resistant ropes may be used as boom hoist reeving when load hoists are used as boom hoists for attachments such as luffing attachments or boom and mast attachment systems. Under these conditions, all of the following requirements must be met:

The requirements in ASME B30.5-2004 sections 5-1.3.2(a), (a)(2) through (a)(4), (b) and (d) (incorporated by reference, see § 1926.6) except that the minimum pitch diameter for sheaves used in multiple rope reeving is 18 times the nominal diameter of the rope used (instead of the value of 16 specified in section 5-1.3.2(d)).

The operating design factor for these ropes must be the total minimum breaking force of all parts of rope in the system divided by the load imposed on the rope system when supporting the static weights of the structure and the load within the equipment"s rated capacity.

Wire rope clips used in conjunction with wedge sockets must be attached to the unloaded dead end of the rope only, except that the use of devices specifically designed for dead-ending rope in a wedge socket is permitted.

Prior to cutting a wire rope, seizings must be placed on each side of the point to be cut. The length and number of seizings must be in accordance with the wire rope manufacturer"s instructions.

Wire ropes can be seen everywhere around us, they are made of strands or bundles of individual wires constructed around an independent core, suitable for construction, industrial, fitness, commercial, architectural, agricultural, and marine rigging applications.

Wire rod is made from high carbon steel wires(0.35 to 0.85 percent carbon) in a hot rolling process of a required diameter, usually from 5.5mm to 8 mm.

Wire rod is drawn to the required diameter by the 1st drawing machine after descaling dust and rust, adding mechanical properties suitable for application.

Positioning the wires different or the same size lay in multiple layers and same direction, or cross lay and diameter is maintained by one-third of the rope size.

So in theory, it is very simple to manufacture wire ropes. However there are many more details that must be closely monitored and controlled, and this requires time and experienced personnel since it is a super complicated project you cannot imagine.

Higher strength-to-diameter due to compacted wires in the strands. With increased metallic area, it provides rope strengths equal to 6-strand XXIP IWRC ropes of the same diameter.

Resistance to bending fatigue due to the uniformity of the wires within each strand. The strand’s outer surface is smooth, reducing contact pressures between the rope’s strands and radial pressures as it operates over sheaves and drums. This substantially cuts rope expense and extends service life.

Technical scheme: in order to realize foregoing invention object, the technical solution adopted in the present invention is: a kind of anti-rotation alternatelaywirerope, comprise right-laid and left-hand lay, described steel wire rope is made up of the identical right-laid of quantity and left-hand lay, the sth. made by twisting of each adjacent layer stock is on the contrary, namely described right-laid and left-hand lay are alternately arranged, and the levels stock of any right-laid is left-hand lay, and the levels stock of any left-hand lay is right-laid.

1, a kind of anti-rotation alternatelaywirerope of the present invention has the advantage of non-spinning wire rope and Lang lay rope, variantly to be alternately arranged in rope to stock, add the contact surface of steel wire, mechanical property also than non-spinning wire rope and Lang lay rope good, by to Mechanics Performance Testing of the present invention and adhesion test, select same materials, its performance change is as follows:

2, the present invention can substitute original left-hand lay wire rope and right-hand lay wire rope half and half completely, the situation that combination collocation uses.

As shown in Figure 1, the rope of non-spinning wire rope to the sth. made by twisting of stock to contrary, twist with the fingers to point sinistral coiling and a dextrad spiral.If rightlay rope is namely for be twisted into stock by steel wire rope by sinistral coiling, then make rope by stock to dextrad spiral turn.

As shown in Figure 2, the rope of Lang lay rope to the sth. made by twisting of stock to identical, it is twisted with the fingers to being also divided into left and right sth. made by twisting, is twisted stock as right-laid is silk along wiring, and stock is twisted rope again and is dextrad spiral twisting and forms.

As shown in Figure 3, a kind of anti-rotation alternatelaywirerope, comprise right-laid 1 and left-hand lay 2, described steel wire rope is made up of 3 bursts of right-laid 1 and 3 bursts of left-hand lays 2, and described right-laid 1 is alternately arranged with left-hand lay 2, i.e. the levels stock of any right-laid 1 is left-hand lay 2, the levels stock of any left-hand lay 2 is right-laid 1, the sth. made by twisting of each adjacent layer stock, on the contrary, makes the twist stress of stock mutually balance, reaches good anti-rotation effect.

1. an anti-rotation alternatelaywirerope, comprise right-laid (1) and left-hand lay (2), it is characterized in that: described steel wire rope is made up of the right-laid (1) of equal number and left-hand lay (2), described right-laid (1) and left-hand lay (2) are alternately arranged, namely the levels stock of any right-laid (1) is left-hand lay (2), and the levels stock of any left-hand lay (2) is right-laid (1).

Rotation resistant wire rope refers to a series of steel ropes which minimizes the tendency to spin or rotation under load. These wire ropes boast special design - the outer layer is twisted in the reverse direction of inner layers for counteracting torsional forces generated from multi-layers of strands.

To achieve the resistance against the spin and rotation, all wire ropes are composed of at least two layers of strands. In general, more layers a rotation resistant wire rope has, more resistance it will boast. For example, 2-layer ropes is much easier to spin and rotate than 3-layer ones. Meanwhile, if one end of free rotation is allowed, 2-layer rope can only develop 55% to 75% of its breaking strength comparing with 95% to 100% of 3-layer ropes.

The 3-layer rope with more outer strands is capable to distribute more radial pressure onto inner layers and ideal for larger mobile such as all tower cranes.

Wire ropes with 8 to 10 strands & 2-layer constructions without reversely twisted inner strands have very similar appearance to rotation resistant wire ropes, but they are not.

Rotation resistant wire ropes are considered to be less stable needing to be handled and installed with great care. They must be taken to avoid high loads with small diameter sheaves.
