Opis: 6 Factors to Consider When Choosing Chain Lifting Slings The Occupational Safety and Health Administration (OSHA) is a body in the United States that plays a critical role in enhancing workplace safety around the country. If you operate a manufacturing company, you must be OSHA compliant so that you can avoid being on the wrong side of the law and so that your employees will be protected from harm. One of the main safety issues that you need to prevent in your manufacturing entity is injuries associated with falls. Several fall protection measures, which have been in place since 1971, govern workplace safety practices. To prevent falls and associated injuries, you must use the right types of lifting slings in your lifting operations. Given that there are several types of lifting slings, some people find it hard to select the best chain sling. This article highlights some of the factors that you need to consider when it comes time to buy chain slings for your company. 1. Weight and Strength of the Load Every time you evaluate different types of lifting slings for your operations, consider the weight and strength of the load. It’s common to see a load falling and breaking, especially it isn’t well-supported from the sides. Use strong rigging when dealing with a heavy load and provide support from all directions. Providing support from the sides will prevent falling, thereby preventing injuries to the workers on site. 2. Sling Flexibility It’s common knowledge that alloy lifting chain slings are flexible enough and can easily be stretched by a heavy load. There are other types of lifting round slings that can be stretched as well. Although this is not a very attractive property of lifting slings, it’s useful in adjusting the load’s center of gravity. This flexibility prevents the load from leaning on one side, which is extremely dangerous in the workplace. 3. Temperature Limits When choosing lifting slings, make sure that you pay attention to their temperature limits. Lifting slings have been made to accommodate temperatures of up to 1,000 degrees Fahrenheit. Anything beyond these temperatures could be catastrophic. If you’re buying chain slings to lift heavy machinery and equipment in harsh conditions, make sure that you check the temperature standards. The chain sling and lifting clamps you choose should be able to withstand excessive temperatures without stretching or melting. 4. Sling Ratings Most of the slings available have industrial ratings, which indicate specific conditions of use. Some of the specific details that will be indicated include temperature, load, operational conditions, and how they are attached to the load. Make sure that the chain sling with hoist that you will be getting meets the sling ratings consistent with your needs. If sling ratings and your needs don’t align, this could spell disaster for your workers. 5. Wear and Tear Resistance Chain slings are exposed to heavy stretching and lifting of very heavy loads. Therefore, signs of fatigue, wear, and tear is a very common problem encountered when using lifting string. When buying a lifting sling, try and find a sling that can withstand fatigue. You should get a chain polyester sling that does not crack when bent by a small radius. Get a lifting sling that can withstand wear and tear to serve you for several years. 6. Lifting Points Before making a purchase, make sure that your lifting sling has proper lifting points on the load. There should be a mechanism which allows your slings to be attached to the load. Otherwise, you will have to come up with methods of attaching the chain webbing slings to your loads. Check that the holes are big enough to accommodate the entire weight of the load and prevent falls. There are many different types of lifting slings available to you. Therefore, you have to conduct an exhaustive analysis before deciding on which lifting sling you need to use. After a careful analysis of your needs, you will easily come up with a lifting sling that meets your needs.

Opis: What are fishing traps WHAT IS TRAPPING? Fishing is one of the oldest ways by which people have fed themselves and their families. Except for gathering shellfish by hand and spearing fish (Figure 1), primitive trapping is probably the oldest form of fishing. In early times, flowing water caused by tidal movement and changes in river and lake levels were probably used to trap fish behind rudimentary barriers, often made from sticks and stones. It is likely that early humans found that fish catches could be improved by driving fish into these barriers. They would have found that catches from these barriers decreased over time, as fish became accustomed to them, and would have had to move the traps to fresh areas where more fish could be caught. It would have been hard work to construct new traps, either by moving stones from the old trap or finding new ones. Primitive fishers probably tried making barriers from lighter, more readily available material such as tree branches, brush and vines (Figure 2). This led to the fishers inventing lighter, movable traps made from brush and nets made from vines which they could carry with them when they moved to new areas. They may even have tried bigger, more complicated corral-type fishing traps in lakes, rivers and coastal waters. Either by accident or by inspiration, fishers then found that: fish were caught in traps as the tide fell, were forced into them by the current or could be chased into them by the fisher; fish entered the trap for protection or simply followed other fish seeking shelter; objects in the traps such as white stones attracted the fish; bits of fish or meat would attract more fish. It is from such beginnings that modern traps and pots have developed. Traps and pots do not seem to have developed in only one part of the world. As fish became an important food source, many types of traps and pots were developed. We will look at some of this variety later in the manual, concentrating on portable traps and fishing net and pots and giving less detail about corrals and other herding devices. WHAT ARE TRAPS? Traps are simple, passive fishing gear that allow fish to enter and then make it hard for them to escape. This is often achieved by: putting chambers in the trap or pot that can be closed once the fish enters; having a funnel that makes it difficult for the fish to escape (Figure 17, p. 20). Smaller traps are generally fully covered except for the entrance or entrances, while larger traps that extend above the water level are often left open at the top. TYPES OF TRAPS AND POTS People in different parts of the world are not always referring to exactly the same things when they use the words "trap" and "pot". In general, traps are large structures fixed to the shore. Pots are smaller, movable traps, enclosed baskets or boxes that are set from a boat or by hand. A simple system for the naming of traps and pots was produced by von Brandt in 1959 for FAO and is used in this manual. General types of traps and pots include: traps that form barriers to fish movement, including walls or dams, fences, fyke nets, gratings and watched chambers that can be closed by the fisher after the fish enters (Figure 2); traps that make hiding places (habitat traps), including brush traps and octopus pots (Figures 3a and 3c); tubular traps, which are narrow funnels or hoses that stop the fish from getting out backwards; eel tubes fall into this category (Figure 3b); traps that are mechanically closed by the fish, including gravity traps or box traps, bent-rod traps (whipping bough traps), torsion traps, drying net and snares; baskets, which are enclosed traps and pots usually with a structure to make escape difficult; they include pots made of wood, wire or plastic, conical and drum-like traps made of netting with hoops and frames (e.g. drum nets) and box-like traps made with strong frames (Figures 4, 5 and 6); large open traps, or fishing net accessories or corrals with a part or mechanism to stop fish from escaping, which can be fixed on sticks or anchors, set or floating (Figure 7); traps set out of the water to catch fish such as flying fish that jump off the tops of waves and glide over the surface when in danger; these can be box-shaped, rafts, boats or nets ("veranda" net types); scoop nets are sometimes used for making fish jump. Pitfall traps can be used for marine animals that migrate over land, such as coconut crabs. In this manual we will concentrate on how you can make and use the various types of transportable traps and pots, the "basket" type. The making and use of other types will be looked at only very briefly. HOW DO TRAPS AND POTS WORK? Trapping is a passive way to catch fish, shellfish, crustaceans (crabs, prawns, etc.) and cephalopods (octopus, squid, etc.) and is different from active fishing methods such as dredging and trawling. Traps can vary, from simple structures such as rock corrals able to hold various fish species passing by, to highly specialized equipment such as lobster pots. Simple trapping and potting can be carried out from small boats or canoes (Figure 8) or from large vessels. The efficiency of fishing with pots or traps can be improved by the use on board vessels of such equipment as power winches and haulers (Figure 9). Fish that enter a trap or pot find it difficult to get out and this gives the fisher time to take the fish that are caught. An advantage of trapping is that it allows some control over the species and sizes of the fish you catch. The trap entrance, or funnel, can be regulated to control the maximum size of fish that enter. The size of the holes, or mesh, in the body of the trap can regulate the minimum size that is retained. To a large extent, the fish species that will be caught depend on the type, model and characteristics of the pot or trap, or cast net being used.

Opis: Are These Chairs the Most Versatile Dining Chairs Ever? For years, I was like Goldilocks when it came to dining chairs. I went through three different sets before finally settling on vintage Paul McCobb Planner Group chairs. They’re decidedly mid-century in their provenance, but really, they’re a riff on a classic spindle chair that could have been designed by the Shakers. I chose them because they are simple, sturdy, and comfortable, but I would also argue that this type of modern spindle chair is one of the most versatile dining chairs you can purchase. Today’s spindle chairs can easily go farmhouse or modern, depending on what table and linens you pair them with. They also have a knack for looking right at home in both casual and formal settings. Many are painted black, which both harks back to traditional Windsor chairs and creates a visually striking silhouette, but you can find them in a range of finishes or paint some in a rainbow of shades yourself, if you want to. If you’re looking to upgrade your dining table setup, consider these eight spindle armchair contenders. They’re all made from solid wood, so they are built to last for years—and will likely still be in style for the long haul. Salt Chair Ton’s beech Ironica chair, sold by Design Within Reach as the “Salt Chair,” is an icon in its own right. The company has been selling this slender take on a spindle for more than a decade and currently stocks four finishes—white, grey, black and natural. This is one instance when DWR is more “within reach.” If you search for the Ironica from other retailers, you will find other colors but with higher price points. J77 Dining Chair Hay is another European manufacturer that makes its own modern take on a spindle chair. Their J77 dining chair is a personal favorite, thanks to its stylish, lower-profile back. This design is part of Hay’s 2011 relaunch of furniture originally made for FDB, the Danish Consumers’ Co-operative Society in the 1940s, and it comes in a few different colors as well. Magnolia Home Vermont Chimney Dining Side Chair Of course Joanna Gaines, the queen of modern farmhouse style, has not one, but two, spindle chairs in her collection for Living Spaces. This particular style skews a little more on the rustic side and has just the right proportions for a smaller dining area or breakfast nook. NORRARYD chair IKEA discontinued their OLLE chair, which was my favorite of their spindle dining chairs and the perfect match to my son’s junior chair, but they do have an option in their current catalog. The NORRARYD chair, which comes in black and white, costs just $75, so it’s a great budget option, even if the OLLE was a little more sleek. Taylor Solid Wood Dining Chairs Joss & Main sells many takes on a spindle chair, but the Taylor Solid Wood Dining Chair comes in an interesting two-tone colorway that sets it apart from many of the others on the market. These would be at home in any Scandi or farmhouse modern decor scheme. Windsor Dining Chairs West Elm’s Windsor Dining Chairs are a surprisingly affordable option at less than $100 apiece. These are a collaboration with the London-based designer Aaron Probyn. You’ll have to wait a little while for these, since like many of the brand’s furniture pieces, they’re backordered until October. If you order now though, you’ll have them well before hosting Thanksgiving (if that’s a possibility this year). Thatcher Chair If American-made is important to you, the Thatcher Chair with bar stool from Room & Board is a solid but expensive option. The back is slightly higher than most dining chairs and dining table, which creates a dramatic silhouette. Crafted from maple with mortise-and-tenon joints, you can consider this style an heirloom in the making. Spindle Solid Wood Windsor Back Side Chair Want to make a bold move? Try this set of chairs finished in a shiny, electric shade of raspberry. They’re the perfect way to perk up a white tulip style table and can also work with blonde and mid-tone woods, too.

Opis: Short Review About All Types of Busbar Bending Machines Facilities Busbar bending systems are produced to facilitate bending busbars for switch boards and switch gears manufacturers these systems are present in 4 types: 1-Manual busbar bending tools 2-Hydraulic busbar bending tools 3- Simple hydraulic busbar bending machines. 4-Professional busbar bending machines. At Manual tools operator should bend busbar via hand force and it is suitable just for small size if busbars, it could bend busbars at normal axis and measurement is possible just with operator eyes . repeatability and accuracy depends on operator skills. At hydraulic busbar bending machine and tool, We have some condition for accuracy and repeatability but operator needs low force for doing job. This type is suitable for sites or places that electricity is not available and for small jobs. Simple hydraulic busbar bending machines are a good choice for small shops or factories that need bending busbar processing machine in normal axis away. Measurement of angles are by mechanical or digital angel indicators. Mostly they have “V” type head that cause two lines behind of busbar after bending they don’t calculate spring back and operator should consider and compensate this fault at bending process. Professional busbar bending machines are suitable for Professional usurers.Bending head is powered with two routable plates to prevent any damage at surface of bus bar after bending. It has high technology angel measurement system that calculate spring back (spring back compensation system) and final bends adapt to desired angel with high accuracy. That’s why at, switch gears geowy we are faced to various types of bending requirements this machine should response to most of them. Edge bending mold: At switch gears some time designer needs to bend busbars from edge especially at electrical keys they need more space for connection’s and edge bending allow them to have enough space. Edge bending mold is a good solvation for this purpose and installable at professional busbar bending machines head. It should keep two main surface of busbar to prevent any bulge at surfaces.
