  1. Rope clamps are not laid crossly. The interval of rope clamps should be about six to eight times the rope diameter (the clamp interval of 16 mm wire rope should be 96-128 mm). Another standard requires a clamp interval of 150 to 200 mm. The fastened extent should take wire rope deformation to one-third as standard
  2. The recommended clearances are 1.5 mm up to rope diameter of 28 mm and 3 mm for rope diameter above 28 mm. The groove diameter of the pulley or sheave should always be larger then actual diameter of the rope. But if the groove diameter is too large the rope will tend to flatten and if it is too small pinching or rope will take place
  3. Ratio B =22.5 (sheave diameter) = 303/4 (wire rope diameter) Ratio B =12 (sheave diameter) = 163/4 (wire rope diameter) The relative fatigue bending life for a ratio B of 16 is 2.1 (see above Table) and ratio B of 30 is 10. Relative Fatigue 10 = 4.7Bending Life = 2.
  4. Overall, 7x7 is used when flexible pieces are required and 7x19 is employed when an even greater level of flexibility is preferred. If you have to make slight bends, then 7x7 ropes may be preferred. Mechanical assemblies that call for sheaves and pulleys work well with 7x19 pieces
  5. How Sheave Size Affects Wire Rope Strength. Severe bending is a major cause of short rope life. By contrast, the larger the sheave diameter, the less wear on the rope and the greater its strength efficiency. Study the graph Strength Efficiency of Wire Rope
  6. Hang these pulleys from hooks, screws, and bolts to assist with horizontal pulling or to guide a rope.. Pulleys with two grooves are for use where multiple pulleys move a single load, such as block and tackle systems. They require about half the force of a single-groove pulley to move the same load. They have a bracket on the bottom for tying off one end of your wire rope
  7. The specification is covering the general requirements except for man riding purposes like lifts and escalators. The three grades recommended are tensile designation of 1570,1770 and 1960. The diameter of ropes covered range from 8,13 to 40 mm. Where fibre core is used it shall be of soft jute fibre. Refer Table 1 & 4 of IS 185

Also known as sheaves, use these pulleys to assist with horizontal pulling or to guide a rope. Pulley Diameter Checkers Also known as groove gauges, these measure the groove of your pulley to check for wear as well as determine the correct wire rope size Light duty pulley, suitable for wire antennas, etc. 1 7/8 nylon sheave, zinc plated frame with swivel eye. Handles up to 1/4 rope. Light duty stealth pulley, suitable for wire antennas, etc. Small size is almost invisible from the ground. Red acetal sheave is 7/8 in diameter and UV resistant Also, pulley diameters less than sixteen rope diameters fall into a range in which cable life is relatively low. The life of steel cable pulleys is reduced as the groove radius changes from the contour of the cable to a flat surface. For maximum cable life, the groove should make contact with the cable on at least 1/3 of the cable circumference

Rope - Ropes, bungees, straps & chains - B&

It is recommended to have a minimum shoulder width (distance between the outer edge of the rim and inside the groove) of 1/8. This allows for sufficient side loading support. With this, a calculation can be done to determine the width of the sheave at the rim Effective Sheave Size Wire ropes are manufactured in a great variety of constructions to meet the varying demands of wire rope usage. Where abrasion is an important factor, the rope must be made of a coarse construction containing relatively large outer wires. In other cases, the great amount of bending to which the rope is read more

Minimum 0.53 to 0.535 x d. Maximum 0.55 x d. Recommended: ≈ 1% over the actual wire rope diameter. Groove depth (h): Recommended: ≈ 1.5 x d or d x √2. Sheave throat angle: For normal applications use 35° to 45° opening. Applications with deflection angles of more than 1.5° use 60° opening. Opening angles below 35° must be avoided Because of the wide range of rope use, rope condition, and exposure to the various factors affecting the rope, it is impossible to make blanket recommendations as to the correct choice of rope to use. However, we have provided the tensile strength for each diameter and type of rope. These strengths are based on tests o wire rope diameter by about 5%. This allows for the tolerance in the rope diameter and assures good support for the wire rope. The groove depth should be at least 1.5 times the rope diameter to prevent jumping. A groove angle (throat angle) of between 30° and 45° assures the best support for the wire rope. When usin

  1. A wire rope with a strength of 10,000 pounds and a total working load of 2,000 pounds would be operating with a safety factor of five. It is not possible to set safety factors for the various types of wire rope using equipment, as this factor can vary with conditions on individual units of equipment
  2. The first clip near the pulley should be 1 pulley diameter distance from the center of the pulley and achieve a 60 degree included angle between the live and dead end. Fist Grip Clips Fist grip clips are a newer take on wire rope clips and are designed to make installation easier

Wire rope can be damaged by being bent too sharply, so the diameter of the sheave in pulleys or of windlass drums is important. Manufacturer's recommendations regarding proper sheave size differ. The Coast Guard's rule of thumb is that the diameter of the sheave should not be less than 20 times the diameter of the wire rope Maximum cable diameter (including jacket): 3/16 will replace the OEM 5.5 diameter pulleys found on Universal brand equipment. Cable groove is 5/16 deep. Cable groove is 5/16 deep. The hub width is 5/8 (.625) and provides a .050 extension clearance on each side of the pulley - which is much less than the typical .125 provided by our.

The #166 pulley features swivels. These are important because rope twists under tension. This can twist your antenna and this is important in some configurations. #166 Bullet Block. Sheave diameter = 1.125. Line size = 5/16. Breaking strength = 2000 pounds. Shackle pin diameter = 3/16 rope to the drum. The length of wire rope used for anchor wraps must be added to the total travel distance to deter-mine the length of the wire rope needed for the application. a = length of anchor wraps in feet a = ((D + d) x . π. x N) ÷ 12. D = diameter of drum in inches d = diameter of wire rope in inches. π = 3.1 Essentially it's the cable thickness and cable diameter. 3/8 cable can hold the most weight, but it really isn't that necessary as it's primarily for zip lines over 1000 feet! For example, our Alien Flier zip line kits use 3/16 or 1/4 diameter galvanized steel cable which can withstand weights of up to 250 lbs

The rope is very popular in diameters from 3mm to 16mm and is used on a variety of applications. 6x19 FC and 6x19 WSC (7x19) is very flexible in diameters 3mm to 6mm and is used for many requirements where wire ropes are running over pulleys. 7x19 construction is readily available in both galvanised and marine grade stainless steel Example: What is the minimum bend radius of a 1/0, 5 kV, SHD-GC cable? Answer: SHD-GC is a shielded mining cable.According to Table 1, the minimum bend radius is found to be six times the cable's overall diameter. The overall diameter of the cable is given as 2.08 inches in the product catalog Assuming the rope is 7 x 19, this puts the ratio of drum diameter to wire (not cable) diameter at about 250. The U.S. Steel Wire Rope Engineering handbook recommends a ratio of 900 for elevators. This would put the drum diameter at almost 15. You should consider whether or not to use a spiral grooved drum. If not, be sure to wind the rope on.

The Speed Ratio is the ratio of angular velocity of the input pulley of a system to the angular velocity of the output pulley. If you've calculated gear ratios, it is almost exactly the same! This is all based on a pulley's reference diameter, as defined below: Reference/Pitch Diameter: The working diameter of the pulley, where the belt or cable contacts the pulley One thing I have found, though, is that the dual-material ropes, which almost universally have white nylon as the inner rope material, will last longer and maintain their flexibility better if you use larger diameter cord. I bought a huge roll of 1/8 dacron-covered antenna rope. It was okay, but it got brittle after a few years This is a wire rope with a high strand -- a condition in which one or strands are worn before adjoining strands. This is caused by improper socketing or seizing, kinks or dog-legs. At top, you see a close-up of the concentration of wear. It recurs every sixth strand in a 6 strand rope.
