CHAIN HOISTS

Chain hoists (sometimes referred to as chain falls or their older term, ‘chain blocks’) are popular piece of equipment to lift heavy loads. A chain hoist is durable and allows heavy loads to be lifted with ease since they require much less strength on the part of the rigger. However, this means they’re more likely to be abused since they typically make a lift much easier, but are not suited for every application.

Rigger Colin Grieg of Brampton, Ontario shared what to look for when inspecting your chain hoist and tips for use.

Before you install your chain hoist, check: chain hoist, Welcome to Ontario: brampton riggers talk chain hoist safety, hercules slr

  • Clean the load chain with a solvent, then add slack to the chain and make a link-by-link inspection for nicks, gouges, twisted links and excessive wear or stretch;
  • That the load chain anchor pin is in good condition;
  • That the top and bottom hook safety catches are operating correctly;
  • Check hooks for cracks, damage, distortion and excessive throat opening – a damaged hook often means it was misused and should be removed from service;
  • Hooks swivel freely;
  • Check name plate and see that SWL, ID number and colour code (if used) are clearly visible.

After installation and mounting, check:

  • That load chain sits correctly in the pocket wheel. To do this, run the unloaded hook up and down a reasonable distance – the chain should run free of snags or binds;
  • The hoist is rigged to lift in a straight line from hook to hook;
  • The hoist is free to swivel on the upper hook;
  • For damage on the handwheel and gear covers.

CHAIN HOISTS: hand chain

Although hand chains are not load bearing, make sure:

  • The chain is free of twists and damage to links;
  • The chain is smooth to touch and ‘joint’ links sit firmly in the chain wheel’s pocket;
  • The chain wheel turns freely with no signs of a bent spindle, buckled wheel or damaged ‘chain pockets’;
  • Make sure operation in ‘hoist’ mode produces a ‘hard’ sound – this is the sound of a ratchet running under a spring-loaded pawl.

CHAIN HOISTS: safety first

  • If the chain’s twisted, don’t use the hoist;
  • Don’t use the load chain as part of a sling configuration;
  • Chain hoists can only be used at its maximum capacity to lift a load vertically – if you must lift a load at an angle, the hoist’s capacity is greatly reduced;
  • Don’t operate a chain hoist beyond the capacity specified – you will cause the bottom hook to run beyond it’s range of lift, and possibly add too much weight to the load-chain slack-end anchorage;
  • Don’t lift a load beyond it’s specified SWL (safe-working load);
  • Don’t let dirt, grease or other harmful debris/chemicals to collect in the load’s profile or hand-chain wheels;
  • Don’t use your load chain if it jumps, is not ‘smooth’ or has marks – this means it’s likely ‘out of pitch’ and should be replaced and removed from service;
  • You should not need extra force/strength to operate your chain hoist – if using extra strength, stop the lift immediately and find the cause. (An easy tip? If it takes more than one man – something’s wrong!)

CHAIN HOISTS: post-mount & pre-use 

After you mount your chain hoist but before you actually use it, you should inspect the following:

  • The chain hoist shouldn’t be allowed to lay against a support, since this can cause the hook or frame to bend and damage the unit;
  • Make sure the hoist can swivel through 360° on the top hook;
  • Make sure the ‘member’ the hoist hangs from is sat all the way in the middle of the chain hoist’s saddle.

CHAIN HOIST: crane hooks

When you suspend a chain hoist from a crane hook, stay safe with these tips:

  • The chain hoist’s SWL will be reduced by 15% – this allows dynamic loading;
  • A safety link with a SWL of 5 times the load weight should be fit between the crane hook and load shackle;
  • Before you hoist with a crane, conduct a short lift test with both to make sure the hoist brake is locked.

CHAIN HOIST: storage 

To store your chain hoist:

  1. Raise bottom hook
  2. Wrap load chain
  3. Wrap hand chain
  4. Secure ends

When storing your chain hoist, be sure to: 

  • Lubricate chain hoist with oil or grease – be careful, as misapplied lubricant may enter the brake disc and cause it to fail under the load;
  • Make sure you have a dedicated spot to store your chain hoist – this place should be dry and free from injurious pollution and extremes of temperature;
  • Chain hoists should be suspended by their top hooks, and the hand chain should be clear of the ground – this will prevent damage to the chains;
  • Don’t use strong solvents on your chain hoist – ensure wet or dirty chain hoists are clean before storing.

CHAIN HOIST HOW-TO: light load brake lock-out test

  1. Suspend chain hoist from a suitable lifting point, and apply a load test of 5% chain hoist SWL to the load hook;
  2. Stay clear of the load – raise test load 70 to 100mm from the ground;
  3. Enter restraint pin through lack side of load chain;
  4.  Operate the chain hoist and lower the direction until the restraint pin gives a lock against the heavy pull of the chain hoist;
  5. Remove the restraint pin and make sure the brake engages right away, which will stop the load from dropping;
  6. If the load drops – don’t use the chain hoist. Remove them from service, and have them repaired.

Women in Industry – Angela Penton, Improving Processes

Angela-Penton

When Angela Penton returned to NSCC at 39, she’d already achieved success as a chef, a landscaper, a textile artist and a metalsmith. What she felt was missing, however, was a high school diploma.

“I left high school a year before I graduated,” says Angela. “Back then, you didn’t have to have your high school diploma to start an apprenticeship program, so I left and did cooking at NSCC.”

During that time, Angela’s artistry in the kitchen inspired her to branch out, and she soon found herself in a metalsmithing, design and art history degree, and running her own textile business on the side. As the demands of running a business, attending school and raising a young family became too much, Angela says she had to make a choice. “I left my degree with just a handful of courses remaining.”

Angela Penton 3“I ran my own business for six years, and also supervised at a landscaping company,” says Angela. “But, because I didn’t have my high school or degree, I was very limited in what I could do.”

With her heart set on a more stable and rewarding career, Angela decided she was going to finish what she had started.

Back to class

“I completed my last year of university first. Then, I enrolled in the Adult Learning Program. Because I had just finished my degree I was able to get credit for nearly all the high school credits that I required, except math.”

Through the program, Angela discovered her aptitude as a problem solver.  “I realized I really wanted to change careers and do something technical –– something that would allow me to get into a management role.”

Angela says she saw NSCC’s two year program options as the fastest route to starting a new career. “I wanted to get some real intensive education that would allow me to go right into the work world.” She adds,

“I looked through all of NSCC’s programs and I kept coming back to Industrial Engineering Technology because I saw that these professionals were in every industry. It was something that didn’t narrow my opportunities, as many of my life choices had up to that point.” ~ Angela Penton

Angela admits she was scared that she was “too old” to go back to school and worried that employers wouldn’t hire someone her age. “I knew I had the potential, but it took the program to retrain my mind to see myself as someone who could operate as a professional at that level.”

Entering the industry

She soon discovered that age wasn’t an obstacle. “I was past that point in life where I was worried about standing out, asking questions or feeling silly. I put myself out there and networked.”

Her hard work paid off. After graduation, Angela was hired as the Process Improvement Specialist for Hercules SLR — a specialty industrial equipment, products and services company.

Angela says her position is the perfect blend of creativity and technical thinking. “I felt badly about leaving my artistic career and thought that I’d never get to be creative again; but, I learned that creativity isn’t just limited to making things or designing things. It’s a way of thinking.”

Hitting her stride

Angela penton 2Angela says she now works to ensure that the company’s more than 400 employees remain focused on reducing operational waste and variance across processes.

Angela explains that a large part of the success of this project and others like it is strategic communication. “The first thing that we learn in the program is the idea that you have to go to where the work is being done — a gemba walk. See it, ask questions, learn from the person doing it and show respect. Treat them like the experts that they are.”

She adds, “It’s only when an Industrial Engineering Technologist does that, that we see the truly meaningful impact we can make.”
