What is a helicopter longline?
A helicopter longline is a lifting rope system designed to connect a helicopter to a suspended external load during helicopter cargo operations.
What are helicopter longlines used for?
Helicopter longlines are used to lift and transport external loads during industrial operations such as utility work, forestry operations, construction, and remote delivery.
Are Barry helicopter longlines designed for external load lifting?
Yes. Barry helicopter longlines are engineered and manufactured for helicopter external load lifting in industrial and utility environments.
Are helicopter longlines considered life safety equipment?
No. Helicopter longlines are lifting equipment for external cargo operations. They are not designed for human suspension unless specifically certified and approved for that purpose.
What is the Working Load Limit (WLL)?
The Working Load Limit (WLL) is the maximum safe operational load the longline can carry. It is indicated on the product label and must never be exceeded.
What is the difference between WLL and Minimum Breaking Strength (MBS)?
The WLL is the safe working capacity. The MBS is the laboratory-tested breaking force. Always operate below the WLL.
Can helicopter longlines be used to lift people?
No. They are designed for cargo lifting only unless the system is specifically certified and approved for human external cargo operations under applicable aviation regulations.
Who is qualified to use helicopter longlines?
Only trained and competent personnel familiar with helicopter external load operations and safe rigging practices should use helicopter longlines.
What must be inspected before using a helicopter longline?
Before each use, inspect for cuts, torn fibers, abrasion, melted fibers, chemical contamination, damaged splices or stitching, damaged hardware, and missing or unreadable identification labels.
When must a helicopter longline be removed from service?
Remove it from service if there is excessive wear, cuts, broken fibers, heat damage, chemical exposure, damaged fittings, damaged stitching, or a missing or unreadable label.
What is the maximum shelf life and service life of a helicopter longline?
The maximum shelf life is 10 years and the maximum service life is 10 years. The maximum combined life (shelf life plus service life) is also 10 years. The longline is considered condition-based throughout its life and must pass inspections and maintenance recommendations as specified in the manufacturer’s user instructions manual.
What is shock loading and why is it dangerous?
Shock loading occurs when a load is suddenly applied or stopped, creating force spikes above the rated capacity. It can cause immediate or hidden internal damage.
Can I tie knots in a helicopter longline?
No. Knots significantly reduce rope strength and may cause failure during lifting operations.
Can helicopter longlines be shortened by wrapping or tying?
No. Any modification such as tying, wrapping, or altering the rope reduces strength and is not permitted.
How should helicopter longlines be stored?
Store longlines clean and dry, away from sunlight, chemicals, and heat sources, in a ventilated area. Proper storage reduces fiber degradation and extends service life.
Does UV exposure affect helicopter longlines?
Yes. UV exposure degrades synthetic fibers over time and reduces rope strength. Avoid prolonged exposure to direct sunlight.
How should helicopter longlines be cleaned?
Clean with mild soap and water, rinse thoroughly, and air dry in a shaded ventilated area. Do not use solvents, bleach, or heat drying.
How long do helicopter longlines last?
Service life depends on usage, load cycles, abrasion exposure, environmental conditions, storage practices, and inspection results. There is no fixed lifespan.
Can helicopter longlines be used near sharp edges?
Sharp edges can severely damage the rope. Avoid direct contact and use edge protection when necessary.
What should I do if the longline has been shock loaded?
Remove it from service immediately and perform a detailed inspection. If there is any doubt, contact Barry for evaluation.
Why is the identification label important?
The label provides traceability, product identification, and load rating information. If the label is missing or unreadable, the longline must be removed from service.
Does Barry provide technical support for helicopter longlines?
Yes. Barry provides technical support, documentation, and guidance for helicopter external load lifting systems. Visit www.barry.ca or contact Barry directly.
