How does your current hoist brand stack up against Vitali-Intl? Vitali-Intl hoists are equal to or better than the next two major competitors!

We often hear, "I like my current hoist brand and supplier. Why would I change?". The simple answer is . . . the price!

Vitali-Intl Hoists also have the SAME SAFETY CERTIFICATIONS as the competition. Every Vitali-Intl hoist comes with a manual, parts list, and Certification of Compliance. Vitali-Intl Hoists are ANSI/ASME b30.21 and HST-3 compliant.

Northern Strands is able to offer a large variety of products for tow trucks. Between our five divisions, we can equip tow truck operators with numerous products to help get the job done. 

We offer wire rope as well as Dyneema rope cut to customized lengths for tow truck drivers. Dyneema rope is a synthetic rope that has a comparable breaking strength to that of wire rope. This synthetic rope won't kink, curl, or splinter and has minimal stretch with no rotation. 

Northern Strands can also provide tow truck operators with different configurations of Grade 70 Transport Chain. This chain is high tensile carbon steel, heat treated, and is available in custom lengths. We also offer Grade 70 Grab and Slip Hooks along with Ratchet and Lever Style Load Binders.

What is Dyneema? Dyneema rope is a brand name of synthetic rope that is made from Ultra High Molecular Weight Polyethylene (UHMWPE), which is the world's strongest fiber and gives it an ultra high breaking strength.

How Strong is it? Dyneema rope is very strong. It is 20% stronger than wire rope of the same size and 7 times stronger than wire rope of the same weight.

What about Abrasion? Dyneema has the highest abrasion resistance out of any synthetic rope in the industry and is widely used in Canada by trans-oceanic shipping companies for towing and mooring their massive container ships. In Saskatchewan and the prairies Dyneema rope is most often used on ATV winch cable, flat deck winch cable and tow trucks winch cable. 

Why does this matter? Northern Strands supplies tow ropes, ATV winch lines and other accessories made from Dyneema ropes for those occasions where you need the strongest rope available and don't want to lift a big heavy wire rope. Northern Strands manufactures winch lines with hook made from Dyneema that make use of a standard eye hook for attaching to anchor points when a vehicle such as a ATV Quad or Side by Side gets stuck to the point where it needs to be winched out. The advantages of using Dyneema in these situations are huge as the rope is not only immensely strong. 

Additional properties of Dyneema rope

• Incredibly light, Dyneema will float on water.
• Literally a rope, which means that it does not kink or tangle like wire rope does, especially on the smaller drums of a quad winch, and there is no risk of puncturing your skin from a broken wire.
• The same material used in the most ultra-modern body armour that is currently preferred to Kevlar as it performs the same wet or dry.
• Woven instead of wound; meaning that Dyneema rope is torque neutral, where wire rope will unwind when subjected to extreme loads.

When conducting work site inspections, audits, or periodic rigging inspections, it is not uncommon to have to take anywhere from 80% -100% of the synthetic web slings out of service. There are a large variety of reasons a synthetic sling, “gets itself” into such a state of disrepair, but one thing that comes up from time to time when you ask a sling’s user why it is still on the rack in a clearly damaged state, a typical response might be:

“Oh, well you can’t see the red marker threads, so I thought they were still good…?”

Unbeknownst to some, many synthetic slings can be cut completely in twain and there will be no evidence of the aforementioned “red marker threads” whatsoever.

Backstory: some sling manufacturers would weave a different colored thread into the web sling material as a way to warn users of excess wear/abrasion/etc. The idea was that sling users would be able to more quickly identify a worn out sling by seeing the different colored thread.

So now we can see the issue that I have with this: the manufacturers added a feature to help sling users identify worn web slings and then sling users eventually turned it into a Go/No-Go gauge. This is made even worse by the fact that many, many slings do not have red marker threads of any kind. And even when slings do have them there can be many other reasons to take a synthetic sling out of service before they become visible.

If you’re noticing a trend like this on your worksite inspections follow this link http://www.northernstrands.com/training.aspx and we can discuss how the Northern Strands Below the Hook Rigging Training program could help you and/or your workforce learn where to draw the line and take slings and other rigging out of service before they become a hazard.

Have you wondered why rigging experts always suggest a sling that has a significantly higher breaking strength than the actual weight of the load you are lifting? The manufacturers know that the rigging used in overhead applications need to have room for error. This is known as the Safety Factor.

Northern Strands manufactures wire rope slings rated up to 36,000 lbs and sells round synthetic slings that are rated up to 140,000 lb capacity. This capacity is the Working Load Limit of the sling, which is the maximum amount of weight or force that the sling's user is allowed to put on the sling. Note: These slings do not break at the working load limit. These slings are designed with a safety factor of 5:1. This means that 5 times as much force as the working load limit has to be applied to the sling before it potentially fails. This means the wire rope slings have a Breaking Strength of up to 180,000 lbs and the round synthetic slings can withhold up to 700,000 lbs.

Why are these capacities reduced by such a drastic degree?

Among others, here are 3 good reasons:

1. Shock Loading - Unexpected drops where the load can accelerate and then must be 'caught' by the slings.
2. Wear - Working load limits are based on slings in brand new condition and a safety factor can help account for normal wear and tear until it is deemed unfit for further use.
3. Uneven loading - Slings are made up of either wires or fibers that must all share the weight of the load evenly. If any situation arises where the sling is bent or wrapped around an object, there is potential that some of the wires or fibers will be taking on a greater share of the load than others.

The Northern Strands Sling Calculator has been designed to assist you in selecting slings with enough load carrying capacity for your lifting applications. It is your responsibility to assure that the slings you use are appropriate for your application.  http://www.northernstrands.com/sling-calculator.aspx
