e-lyne, the digital era’s horizontal lifeline system

E-lyne is the engineered fall protection system developed by Elytra. With almost three decades of experience in the installation of such systems, the design of our very own system has focused on ensuring that technical improvements go hand in hand with technological solutions.

Technical improvements:

  • Certified to EN 795:2012
  • Spans of up to 18M
  • Lower end anchor forces.

Components of the engineered fall protection system

Line tensioner
Tensor de e-lyne
1 tensor 2 pre-tensions

We have modified the cylindrical body of the tensioner to develop an interior mechanism which, based on the compression exerted during the line tensioning operation, releases the new rod housed inside.

This allows the installer to select, from the possible pre-tensions permitted by the lifeline, the pre-tension at which the lifeline will be installed once the final tensioning operation has been performed.

A single tensioner for all the e-lyne installation models. It can be used for the e-lyne models in which the pre-tension is lower, such as the ARC, or where the pre-tension is generally very high such as the Over Head.

Connector

Designed to be mounted in straight lines of less than 100 metres in length. This part also shows the exact points at which the cable needs to be crimped.

Intermediate guide

With 5 different positions, the intermediate anchor is designed to dissipate the initial impact of the fall.

Traveller

Compact and lightweight, the traveller features a triple safety system that will give you great peace of mind as you work.

Minimises the end anchor forces, making it possible to secure the line ends to less critical points.

e-lyne absorbedor
Standard post
e-lyne poste standar

At the customer’s request, we can supply standard supports to attach the line to the corresponding structure.

Corner bracket

We can supply brackets with a 90º or 45º rotation. For mounting on either a horizontal surface or a vertical wall. For this latter case, there is the option of either a closed or open fixture.

e-lyne ARC, Load Reducing Anchor

e-lyne ARC
The spring
This is the most important component of our ARC. Designed to progressively reduce the load generated by the impact, the degree of opening is based on the load transferred by the fall.
Línea de vida e-lyne ARC

Our ARC Load Reducing Anchor, entirely developed by our engineering department, is designed to reduce the high loads that are transferred to the lifeline supports during a fall. It is therefore possible to speed up the lifeline installation process given that there is no need to secure the lifeline to the interior structure of the building. This fast installation in no way impairs the safety performance of the system.

  5. Moisture-proof housing:
    the moisture-proof housing is totally independent of the ARC so that, if there is a need to replace the roof insulation fabric, the same housing can be re-used.
  6. ARC

Mounting on sheet metal or sandwich panel roofing

In this case, the ARC is mounted on corrugated sheets or sandwich panels. The post is secured with American rivets, and neoprene gaskets are used under the ARC base in order to guarantee the watertightness of the holes made.

Mounting on standing seam roofing

When mounted on this type of roofing, the large variety of standing seam gasket types means that the fastenings vary considerable with regard to size and strength. The correct choice of clamp is key to a good result.

This is an item specifically developed for our ARC cans. It makes it possible to install an intermediate one in the same can in which the end of the lifeline is housed.

e-lyne Overhead System, the traveller

e-lyne Over Head
e-lyne over head

We’ve made a few changes to the original traveller on our e-lyne lifeline, adding rollers for a smoother, more seamless travel.

What’s more, this traveller allows you to :

  • Detach it from the line
  • Go round bends.

The same tensioner for different pre-tensions.
As this is a common component for all the e-lyne lifeline models, you can pre-tense our tensioner to 1kN or 5kN, which is the pre-tension of the Overhead line.

The e-lyne OH cable
By introducing the 8mm stainless steel cable in the 1x19 model, we get a lifeline that is more rigid and performs far better with the 5kN pre-tension than the standard option of a 7x7 cable for the e-lyne.

Lifelines on Travelling Cranes and Runway Tracks

Cranes are one of the most common applications for the certified horizontal lines.

Puente grúa linea de vida horizontal e-lyne
Travelling cranes

Movements along travelling crane beams for crane maintenance and repair work can only be protected with flexible horizontal fall protection systems. Let's explain: There is no collective protection for this type of fall, given the fact that railings are insufficient for protecting against inward falls between beams. The fall factor is generally adverse: posts at least one metre high, generally need to be erected in order to prevent an excessive fall.

Carril de rodadura linea de vida horizontal e-lyne
Running Rails

Access to the cranes from their running rails is also a high risk area for different level falls. Access to cranes often involves moving along the running rails. Unless the gangways are extremely wide, these movements are difficult to protect with collective protection systems. In general, these are usually longer routes, in which the fall protection systems are secured to the structure of the industrial building itself. It is also normal practice to mount the lifelines above the user's head in order to greatly facilitate the calculation of the free fall distance.

 

Lifelines on roofs

Fijación a estructura línea de vida horizontal Elytra
Structural anchorage

As already indicated above, cable lines transfer the loads to the end anchor points, multiplying the loads generated at the point of the fall. This is known as the cable multiplier effect.

Moreover, for structural anchorage, the standard establishes that they should be made for double the load calculated.

If the loads sustained at the end points are already going to be high, and given the fall factor 2 used for anchorages of this type, it goes without saying that particular care should be taken over the anchorage place of installation.

Depending on the roof type, these structural members can be:

  • Decking; for roofs with conventional tiles.
  • Truss structure for lightweight roofs; sheet metal, panels, etc.
  • Beams; for roofs with hollow bricks.

Load Reducing Anchors, ARC

When seeking an anchor point to secure a fall protection system, it can be complicated to find the best structural member and difficult to value its cost.

To avoid having to find structural members, someone came up with the idea of Load Reducing Anchors (ARC).

The great advantage of this fixing system is that these anchors reduce the loads to under the load that can be sustained by lightweight roofs. Moreover, they considerably simplify the installation work and the cost can be calculated more accurately.

To achieve this, the anchor posts are equipped with an internal shock absorption system.

They can be installed on:

  • Sheet metal or sandwich panel roofing.
  • Kalzip, standing seam roofing.
  • Inverted or DECK type roofing

Other fall protection system applications

Fall Protection Systems for Train and Bus Roofs

The free fall distance between the roof and ground tends to be very low. In order to minimize the free fall distance, a fall factor 0 system shall be installed above the operator's head.

In addition to the height at which the fall protection system is mounted, with a view to reducing the free fall distance, other factors also come into play.Reducing the catenary of the lifeline spans.

  • Using more rigid cables.
  • Making the lifeline tauter at its ends.
  • These changes have resulted in the creation of specific systems for overhead work.
Fall Protection Systems for cleaning curtain walls and windows

The installation of fall protection systems of this type is not a problem unless the fixing to the structure is complicated.

The necessary free fall distance is not such an important requirement as it was in the application above, unless dealing with windows on the first floor, close to the ground. In this case, the fall protection system shall be mounted with a fall factor of 0.
