HOW TO CHOOSE A FALL ARRESTOR FRO HIGH-ALTITUDE USE

Q
What is a fall arrester for working at height?
A fall arrester is an important component in a working-at-height protection system. It is generally used to provide connection and protection while the worker is moving, and to help reduce fall distance or impact risk in the event of a fall. Common types include self-retracting fall arresters, automatic locking fall arresters, and vertical fall protection devices.
Q
What is the difference between a fall arrester and a safety lanyard?
Both fall arresters and safety lanyards are part of a fall protection system, but they function differently.
A safety lanyard usually has a fixed length and is suitable for defined connection needs.
A fall arrester generally allows the line to extend, retract, or move with the user, and it can lock quickly when a sudden fall occurs.
For jobs requiring a larger movement range or greater flexibility, a fall arrester is often the more suitable option.
Q
What are the key factors when choosing a fall arrester?

When selecting a fall arrester, the following points should be checked first:

  • Working height
  • Working movement: vertical, horizontal, or fixed-position use
  • Working environment: indoor, outdoor, steel structure, tower, construction site, etc.
  • Required movement range
  • Connection method and anchorage position
  • Compatibility with harnesses and other fall protection equipment
  • Housing, rope, or cable material
  • Certification and testing requirements

A fall arrester should not be chosen by line length alone. The real key is whether the full system matches the actual working application.
Q
How should the length of a fall arrester be selected?
The length of a fall arrester should be selected based on actual working height, movement range, and site conditions. A line that is too short may restrict movement, while a line that is too long may complicate system planning. Buyers should also consider anchorage position, working path, obstacles in the area, and required clearance below rather than focusing on product length alone.
Q
What is the difference between webbing-type and cable-type fall arresters?

Different fall arrester materials are suitable for different working environments. In general:

  • Webbing-type fall arresters are usually lighter in weight, easier to carry and handle, and offer greater flexibility during use. They are often suitable for general working-at-height applications, construction sites, or jobs that require better mobility.
  • Cable-type fall arresters are generally more resistant to wear and are often preferred in harsher environments, high-abrasion conditions, or applications where greater durability is required.

The actual choice should still be based on working environment, frequency of use, abrasion resistance requirements, weight considerations, and compatibility with the overall fall protection system.
Q
What type of harness should be used with a fall arrester?
A fall arrester should generally be used together with a full body safety harness, with the appropriate attachment point selected according to the application. A full body harness provides more complete body support and better impact distribution in the event of a fall, which is why it is commonly used in fall arrest systems.
Q
Is anchorage position important when using a fall arrester?

Yes, it is very important. Anchorage position affects the working path, movement range, fall direction, and overall system safety. If the anchorage position is not appropriate, it may reduce system effectiveness and stability. When planning a fall arrester system, buyers should evaluate anchorage position, movement direction, and site structure conditions together.
Q
Does fall arrester selection vary by working environment?

Yes. Different job environments require different fall arrester solutions. For example:

  • Construction sites often focus on durability and movement convenience
  • Steel structure or tower work emphasizes connection stability and movement path
  • Vertical climbing environments may require compatibility with vertical fall protection systems
  • General maintenance work may prefer lighter and more flexible models

For this reason, a fall arrester should be selected according to the actual environment and job type rather than using one model for every situation.
