Hoist (mining) – Wikipedia Ropes for Drum and Koepe Friction Hoists This makes the rope very suitable for multi-layer coiling drums and friction hoists. The modulus of elasticity of locked coil ropes is 14,000,000 lbs./ in.². Hoists. Generally speaking, three types of hoists are employed for shaft use: Parallel drums, onto which ropes are coiled in either one or several layers. Wire Rope Installation – Winch Lines – Cargo Control The whole swift and coil then rotate as the rope is pulled off. This method is particularly effective when the rope is to be wound on a drum. 2) The most common as well as the easiest uncoiling method is merely to hold one end of the rope while rolling the coil along the ground like a hoop (Fig. 22). Wire Rope Handling and Installation | Assembly Specialty … Wire rope should be attached at the correct location on a flat or smooth-faced drum, so that the rope will spool evenly, with the turns lying snugly against each other in even layers. If wire rope is wound on a smooth-face drum in the wrong direction, the turns in the first layer of rope will tend to spread apart on the drum. LeBus International, Inc. The sleeve can be added to the smooth drum either during original manufacturing or after the hoist is in the field. Wire rope savings – Wire Rope is expensive, electro-mechanical cable even more so. Anything that promotes the increased life of the cable can be a huge cost saving.

Wire rope installation guide – Prysmian Group Ordering hoist rope QUANTITY, DIMENSIONS AND STRANDING While the information on the next three pages may be provided on the existing wire rope tag, it should be noted that the tag information may not always be accurate. 1 Count the number of ropes. 2 Determine the length of each rope. This can often be found on the instal-lation layout. Inspection of Hoist Brakes; Control and Holding Brakes … The Operator must test the functioning of hoist brakes on near capacity loads How and when does an overhead crane operator test the functioning of hoist brakes? Federal regulation OSHA 29CFR1910.179(n)(3)(vii) states that: “The operator shall test the brakes each time a load approaching the rated load is handled. Design Manual for Winch Systems – Liebherr Group Determination of the rope, drum and max. winding diameter as well as the gearbox size based on • Rope hoist • Mechanism group • Number of winding layers (1 to 7) • Number of parallel hoists (1 or 2) 26 If required: iteration of the determination of the mechanism if drum speed deviates strongly from design speed of gearbox ( n T < 11 rpm … Mine product news: Synthetic mine hoist rope passes … 24/2/2012 · The first step of the technical feasibility study was to design and proceed with a coiling test that would determine the ability of synthetic rope to spool on and off a multi-layered drum under load, to simulate underground mine hoisting. From Table 2: From Table 1: Total Line Pull Calculation … tices of wire rope manufacturers and assumes uniform winding of the wire rope. In actual practice, drum capacities may be 25-30% less than the values given by this formula due to uneven spacing, loose wind-ing, and overlapping. Drum capacity often determines the winch you select. Most power winches can be equipped with different sizes of wire rope.

Hoist Brakes or Holding Brakes | Konecranes USA Hoist brakes are essential for crane safety. Hoist brakes are an essential safety feature of overhead cranes. Designed to hold a load when the hoist motor is not running, these brakes reduce the risk of falling loads that could result in injury and property damage. This section specifies the performance requirements of hoist, or holding, brakes. mining engineering: Koepe/Friction Hoists Drum hoists are discussed separately in Chapter 13. … • The hoist wheel diameter to rope (lock coil) … Step 6: Select hoist (head) ropes. Cage Hoist. Try 6 lock coil ropes of 32 mm diameter weighing 5.58 kg/m and having a breaking strength (BS) of 890 kN.
