Lifting and Rigging Equipment—Your Hardware Guide

Rigging Equipment

Though some individuals think they can do anything, construction workers are not strong enough to lift and monitor heavy loads. That’s where lifting and rigging equipment comes in.

Building construction and transportation of cargo wouldn’t be possible without the correct equipment. Most of the equipment used to load trucks and harness heavy building components are designed to get the job done fast. These heavy machinery components are also there for safety.

So what kind of rigging and lifting equipment can you get & how versatile are they? Go through the following types of rigging and lifting equipment to find out.

Types of Equipment for the Job

Load Measuring

Most of the time when there’s an exceptionally heavy load that needs to be lifted workers will use load monitoring equipment. The monitoring device is used to weigh loads under heavy stress. They are needed with lifts where the friction of the load could result in more strain on the tackle or hoist.

The monitoring device can also be used when loads that need to be lifted are more than 90% of capacity the equipment can handle. Measuring devices are also used to give the exact weight of a load.

Shackle Equipment

Shackles are manufactured with anchor and chain formations to be used for rigging projects. Typically shackles come with safety bolts, screw pins, and round pins. An anchor shackle has a rounded eye which makes it suitable for attaching multiple slings and hooks.

A Chain Shackle features a straight eye and they’re designed to connect to a single lifting device.

Eyebolts

There are two types of eyebolts; the shouldered or unshouldered eyebolt.

  • Shouldered eyebolts: Used for angular and vertical lifts. When used for angular lifts the shouldered eyebolt should only be used for lifting angles of less than 45°.
  • Unshouldered eyebolts: These components can only be used for vertical lifts as angular lifts will bend the threaded shaft.

The eyebolt is used to firmly attach a securing eye to a structure. They feature self-locking nuts for safety and security.

Usually, the minimum thread connection between an eyebolt and tapped hold is 1.5 times the diameter of the thread engagement. Minimum thread engagement must be maintained for safety purposes.

Hooking Equipment

A hook is typically attached to a hoist and it’s used to lift heavy loads off the ground. Hooks are known to be the weakest component to lifting equipment. They tend to bend if there’s an overload of material being hoisted. To avoid bending, always use a safe working load.

Loads are centralized with full capacity when combining shackles with multiple sling eyes and integrating them onto a hook. Hooks should also feature a safety latch to bridge the throat opening which prevents the release of load lines.

Wire Load Clips

Wire load clips are used to make an eye on a wire rope. You get three different types of load clips:

  • U-bolt
  • Fist grip
  • Collet connection clip

Load clips are never used more than once for an application. They may not have the same torque if they’re used for the second time.

Ring Components

Forged steel rings are not made by welding the rings together. They’re solid rings that are standard in lifting operations. Rings should not be welded closed as they’re susceptible to snapping. Rings should always be inspected for openings, cracks or twists before they’re used for lifting heavy loads.

Turnbuckles

A turnbuckle is used to adjust the tension and length of ropes, tie rods & cables. Typically turnbuckles consist of two threaded eye bolts. For durability and safety turnbuckles should always be forged using alloy steel.

Turnbuckles are rarely used in rigging systems but when they are they should be secured to a frame with lock pins or wires to prevent them from loosening.

Hoists

A hoist is a mechanical lifting device that moves heavy objects vertically and they support hanging loads. You’re able to evenly distribute weight by using pulley systems or gears. Hoists can be a fixed or they can be mobile. They’re designed for:

  • Construction work
  • To lift engines out of heavy trucks or buses
  • Logging
  • Mining
  • Automotive removal

Hooks are incorporated onto a fixed end. The rope or cable is connected to a crane and the hook is used to engage the load.

Manual Hoist

Manual hoists are operated without electricity. A manual hoist uses two different chains called the hand chain and the load chain. The hand chain is used to control the lifting and the lowering of materials. The load chain is used to support the materials being lifted.

Powered Hoists

You get three different types of powered hoists:

  • Electrical
  • Air/Pneumatic
  • Hydraulic

The lifting speed of a powered hoist is a lot faster. Usually, scales can be integrated into powered hoists to measure the weight of a load.

What is Lifting and Rigging Equipment Used For?

If you’re not sure if this article is for you, what we’ve discussed can be used to lift and maneuver heavy objects safely, such as:

  • Hoisting heavy pillars
  • Loading cargo onto trucks
  • Lifting heavy machinery
  • Securing components to a machine
  • Securing cargo
  • Monitoring the weight of heavy loads

Final Thoughts

There are many safety measures construction workers have to adhere to when working with heavy machinery. Always check your construction equipment for any cracks, dents or weak points before working on a site.

When buying equipment always exam hoists, hooks and any connection links to make sure they’ resecure & sturdy. Someone’s life could depend on it.

Pipe Recovery

5 Important Tools For Pipe Recovery Operations

For well lodging and digging you use many types of equipment like drilling tool, lodging tool, measuring tools and more for perfect well. You can attach these tools with a single string or with group o strings and put them down in the wellbore. However, due to some reasons, either the wireline string breaks or the digging tool gets stuck in downhole formations. Does your drilling string often get set stuck inside the well? If so, then use pipe recovery operations to release the string or to make it free from the blocked position. Pipe recovery services use to make the portion of jammed string free from well formations. These services help you in identifying the location of block pipe, to cut the stuck string and finally to bring back the free portion of the pipe from well. If your pipe gets stuck and you wish to release it then, below are some tools that will help to take out the portion of blocked pipe from downhole or well. Free Point Indicator Tool: This tool is used for pipe recovery services to identify the location of stuck pipe in the wellbore. It works by measuring the torque and pressure of wireline in the downhole to identify the location of blockage in the well due to the stuck pipe. You can also use it to judge the stuck point in all type of tube wells, coiled tubes, and well casing. Back Off Tool: Once you are done with a location check of the stuck point of pipe, you might be thinking on the way to release it. There is a back off a tool that helps you to remove the free portion of the string from the well. It works by applying the torque on a stuck portion of wireline and detonate it. Hence the free string gets separated from stuck string and can be pulled up from the wellbore. Chemical Cutter: It is a good tool for the recovery of electric wireline services and is widely used in operations where no need of any torque to pull up the string. It is capable to cut coiled tube, well casing and drill pipe without providing any harm to other portion of pipe or well. These tools are designed to operate in conditions like extreme pressure and temperature which make it best tool for oilfield well. To make a clean cut and not leave any debris in the hole. Radial Cutting Torch: It is lowered down into the well to cut the stuck string. It uses the mixture of powdered metal that a burn with high temperature on ignites and it melts to become molten plasma. This plasma is then ejects through a nozzle onto the target string and cut. Fishing Tool: You can use this tool to release or remove the stuck pipe and any other suspended material from the wellbore. There are many fishing tools available such as spear, overshoot, junk mill and boost basket that help you to recover the stuck string from the well.  A spear is a tool that can fit within the pipe and help to grip the pipe from inside. However, overshoot tool grips the pipe from outside and help to bring it up from the well. Recover the wireline as soon as possible to save the drill time off well. Recovery of the pipe is also a need that protects further damage to the good casing. If you feel that wireline recovery operation is not easy for you then, you may call any pipe recovery service provider.

Apartment Home Hunting Like a Pro

A house is not a home, and neither is an apartment home is where the heart is. If your heart is everywhere, then the very outdoors could be your home—but that’s not the case for most people. The point is, even if you’re just going to rent a place for a little bit, you want somewhere you can rest your heart comfortably. Now what makes you comfortable at your core is necessarily going to differ from that which makes someone else comfortable. Everyone has their own deal makers and their own deal-breakers. Following, we’ll examine a few features of apartment home-hunting that, for the most part, are generally agreed to be relevant. Before we get into them, keep in mind: to get a good idea of what’s available, it’s fundamentally essential that you examine multiple units. Try to look at five, minimum, before deciding. If you can see twenty units and closely examine them all, that’s ideal; but for most, five will be a good minimum spread. That said, consider the following tactics. Techniques To Follow For Apartment Home Hunting Set A Price Range, Consider Travel, Know Leases How much are you willing to spend? This number can’t be static, it’s got to have a range. You can get a better apartment home for less if you’re willing to rent from landlords on the outskirts of the city where you work. However, what you pay in wear-and-tear for your vehicle and gasoline may actually end up being more expensive over the long term. If you found an apartment right on top of where you work in Dallas, Texas, and one on the outskirts of town for half the price, it could be that the centrally-located unit saves you money. The commute in and out of the city center will be an hour, minimum; meaning two hours a day. If you work five hours a week, that’s 520 lost hours a year (assuming you work 52 weeks). If your time is worth $10, that’s $5,200 you’re losing. If your time is worth $100 an hour, then that’s $52,000 you lose in time alone. There’s an opportunity cost to a commute, depending on how productive you are when you aren’t working. That doesn’t take into account gas or wear-and-tear, either. At .58 cents a mile, and 40 miles’ round-trip commute five days a week, that’s $6,032. A long commute can collaterally cost you as much as $11,232 a year. That’s $936 a month. If you’ve got an apartment home right on top of where you work, and you can walk, that’s preferable to the commute even considering the increased cost. The difficulty is how long you’re locked into a lease, and how long you’ll be working where you are. Top-Tier Units Have Collateral Advantages It might be worthwhile to check out some of these good looking apartments in Galleria, Dallas. Sites such as that in the link provide you a broad spread of communities that have varying advantages and benefits. You want the broadest spread of potential units to choose from in order to make the best choice. Additionally, those units should be relatively qualitative. While “home is what you make it” may have some validity, it’s a lot easier to get comfortable in new apartment home where all the appliances work and you can trust your neighbors. Certainly, you can make a home of rent-controlled units or low-income housing options, but that’s going to get iffy real quick; especially when your recovering addict neighbor knocks on your door at two in the morning to borrow rice or toilet paper or something. General Quality Of Units Apartments are generally rentals, so you may not need to find something that has any resale value down the line. You’re looking for a right-now solution. Renting doesn’t build equity. Buying does. If you’re buying a condo or an apartment, that’s a different story. The quality of the unit you inhabit will depend on your overall purpose in purchasing it. Making The Best Choice Know your price range, what kind of travel you’ll have to deal with, how much money you’ll be making every month, how long you plan on staying in the apartment, and what sort of quality you can handle. Once you know these things, look at a minimum of five units which fit such qualifications, and do some. Read Also: Buying A House Vs Renting An Apartment: Which Is More Affordable?

Don’t Forget To Plan For These 7 Hidden Costs Of Moving

Moving is a very expensive decision — whether you DIY with a rented truck or hire the professionals. You probably budgeted for the truck or moving company before you started packing. But these are just some of the most obvious expenses involved in the typical move. Unless you’re a seasoned professional or frequent mover, you may not realize plenty of other expenses are in your future. Things like child sitting, elevator charges, and parking tickets can up your costs significantly. You can usually rely on a line of credit when you’re faced with unexpected expenses. But when you have already put down $2,000 on a moving company, you may not have a lot of room left on this account. Part of managing your line of credit responsibly is learning to anticipate supposedly unexpected expenses before they happen. This article is critical reading for anyone who wants to limit how often they use their line of credit during a move. Planning early means you can start saving for these expenses in advance. 1. Child Sitting If you have children, you might have to think about getting a babysitter for your child. To save money, you can ask friends or family willing to look after your kids. Either way, removing your kids from the equation is easier for you and your movers. That way, you don’t have to worry about them being underfoot when you move heavy furniture. 2. Pet Boarding The same rules apply to your furry children. Keeping your dogs and cats away from the action protects everyone involved. 3. Takeout With your kitchen packed up, you will be relying on takeout and readymade meals far more often. You can save money by preparing frozen meals in advance, moving them quickly from one freezer to the other. Keep shelf-stable snacks handy, too. 4. Parking Tickets  If your moving company parks illegally on the sidewalk or in a no-parking zone, you (not the company) will have to pay the ticket. Avoid this by seeking out a parking permit for your new neighborhood. 5. Security Deposit  That hole your friends caused when they moved your antique armoire? If you can’t patch it up before you move, you might lose out on the security deposit you put down when you first moved in. DIY repairs might help you avoid losing your deposit, but even DIY work costs money. 6. Elevator Fees  If you live in a condo, you will have to book the freight elevator to move your things. Depending on the condo company, they may apply a charge for this elevator. This fee is usually non-refundable and must be paid when you book the elevator. To make matters worse, most moving companies also charge elevator fees if you live on an upper floor. They may also charge stair fees if you live on the top floor of a walk-up. 7. Utility Setup Once you arrive at your new place, you have to set up utilities to heat and power your home. Some utility companies may require you to put down a security deposit before they start the service. They usually ask if you have poor credit or are a brand-new customer. These deposits can be costly, charging as much as twice your average monthly use. Keep this in mind as you create a moving budget. It’s better to struggle to save this amount than the opposite, being surprised by it when you go to hook up utilities! But if all else fails, your line of credit can pitch in.
