design of electric overhead travelling cranes and hoists etc. Breaking load of the wire rope should be 1313×8 = 10500 kg (approx.) Three construction of wire rope are in most common use for the design of hoists etc. 6/19, 6/24 (with fiber), and 6/37 out of these three, 6/37 is preferable, being more flexible than the other two.

supplier any idea of the actual rope design specification. For example, a 6x19 Warrington and the more current 6x25 Filler Wire are both 6x19 classifications but have very different design specifications. Wire rope construction evolved to serve different needs. As buildings became taller, the eight-strand rope was developed for use on eleva-tors.
14. Procedure for Designing a Wire RopeProcedure for Designing a Wire Rope 1. First of all, select a suitable type of rope from Tables 20.6, 20.7, 20.8 and 20.9 for the given application. 2. Find the design load by assuming a factor of safety 2 to 2.5 times the factor of safety given in Table 20.11. 3.
If you want a permanent location for the rope-making machine, plan enough room to make the length of rope that you want. A …
Figure 1: This drawing graphically illus- trates the movement of strands when wire rope is bent over a sheave or drum. Note that the marked area on the outer strands moves as the outer wires elongate and inner wires compress. 26 23 Tight groove contours as a result of wear can have a dramatic effect on rope life.
The aim and objective of this project are to design a small scale 'Automatic Braiding Machine' that fulfills the design criteria and is efficient and practical. Content …
The machine was built to produce 1.5-inch rope for cable railways--80 tons could be loaded at a single spinning, which provided 30,000 feet of unspliced cable at a batch. The demand for ever longer cable car ropes led to its design. It was a vertical machine, standing 64 feet, requiring the machine and building to be built as a unit.
To make the rope spinner, start with a piece of pine (or any softwood) about 1-1/2" thick by 2" wide by 12" long. This can be cut from a two-by-four (2" by 4"), which is a type of construction lumber. Draw the basic shape of the spinner on the wood, following the pattern shown in figure 71. Cut the basic shape with a coping saw.
Seale construction strand make it comparatively stiffer than the filler wire strand, but eight-strand rope is more flexible than six-strand. So a 6 X 25 filler wire has more flexible strand construction, but having six strands compromises overall rope flexibility.However,six times 25 equals 150 wires, which attests to substantial rope ...

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. 1926.1414 (c)
As the rope is tugged, the pulley turns. The force on the rope travels around the pulley to the other end of the rope, so the pulley changes the direction of the force. If you were to attach a weight to one side of a rope, loop it around a pulley, and pull down on the other side of the pulley, the weight would lift up! It's very simple.
in rope design. Below are a few types of commonly found rope constructions. By no means is this a complete list or exhaustive in nature, but it is a sampling of some ropes found on the market today. 3-strand rope: This twisted or laid rope construction uses three strands of twisted filaments and lays them into a spiral, creating a single rope.
this modern groove design can be reduced. Why? With an increase in rope-to-sheave contact pressure, created by the gripping ac-tion (or rope pinching) of the groove, a large arc of contact is not needed to sustain trac-tion. The Undercut U-groove Sheave With the reduction in sheave diameter comes a loss of con-tact area between rope and sheave.

Flexible wire rope is formed by using many small diameter wires twisted around a central core. Wire rope is widely used for hoists, haulage, and conveyor applications, where the wire rope supports tensile loading along its length.
