Samson K-100 Hoist Line: The First Synthetic Crane Rope

Samson rope's K-100 hoist rope is the first of its kind - a synthetic rope to be used with mobile cranes for hoisting applications. Traditionally, steel wire rope has been used for lifting applications with cranes - the K-100 is suitable for crane or truck hoist rope, or mobile crane hoist line applications.

What Are the Benefits of K-100 Hoist Line?

The K-100 hoist rope has a high strength-to-weight ratio, bend fatigue durability and is easy to spool. It has a strength similar to wire rope - but reduces load weight by 80%. It also meets maximum line pull requirements with its 5:1 safety factor.

Samson has coated the K-100 rope in their proprietary coating that includes Dyneema® - this improves its cyclic bend performance compared to sheave applications commonly found on mobile cranes. It has a fibre core/cover - specifically, a polyester control core and a high-modulus (low elasticity) blend.

Samson K-100 Crane Hoist Features

• Corrosion resistant - no rust or lube needed, which helps eliminate environmental concerns
• Easy handling, reeving and installation
• Reduced wear on sheaves and drums
• Reduces number of change outs caused by kinking, bird-caging, or damage from diving
• Reduces risk of hand injuries from broken wires, increased handling safety
• Has same load pull and load chart, but with a 5:1 safety factor
• Standardizes main and auxiliary hoist to one rope
• Torque-neutral construction reduces load spin and cabling
• Resistant to drum-crushing

Safety Factor: Calculating Stress-Based Design Factor

There are different definitions of safety factor across many industries - which is also commonly known as the design factor. The Samson K-100 rope uses the safety or design factor calculation related to rigging and lifting applications.

The safety factor is the theoretical reserve capability of a product, which is determined by dividing the ultimate load by the working load limit (WLL). The ultimate load may also be known as nominal breaking strength. This calculation is expressed as a ratio - the K-100's safety factor is 5:1.

Samson K-100 Hoist Line: Weight Matters

Another benefit of K-100 crane wire is it's weight - as we mentioned, it's 80% lighter than wire rope and can be beneficial for operators who travel during Spring Thaw Restrictions in Canada. Spring Thaw Policies are periods of time during/following Canadian Spring, (specific timelines and affected zones vary from province to province - if you've experienced a Spring in Nova Scotia versus British Columbia you know why!) and limit damage to at-risk roads.

Studies show that pavement reacts to a load 50%-70% greater in the Spring. Basically, the same axle a truck drives on daily can cause 5-8 times more damage in the Spring than any other time of the year, due to the heavier load. For mobile operators with a lot of terrain to cover, the K-100's reduced weight can make your highway travels that much easier.

Samson K-100 Hoist Line: Inspection Matters, Too

No matter how good or durable a rope is, it will show wear and tear after a period of time. Some used rope won't reduce strength, but many will. Before inspection, consider the following:

• The length of rope;
• The time it's been in service;
• The type of work it does;
• Where the damage and the extent of the damage.

On a regular basis, inspect your Samson K-100 rope for the following conditions/damage and take the proper corrective action (repair or retire) based on your findings:

Ultimately, Samson's K-100 crane rope brings increased safety, easy handling and straight-forward inspection procedures. Hercules SLR Business Development Manager, Dwayne Fader says “Steel wire rope will always have its place - but innovations like this that are much lighter and easy to work with are always exciting.”
