Horizontal lifeline Systems

Harcon Service are a leading specialist in the design, supply, installation and commissioning of a number of horizontal cable based lifeline systems.

With our in-house design service and technical support team we can offer a solution to most height safety requirements.

Each system would be designed specific to the site requirements, whether that be direct fix to a solid structure, steelwork, overhead, inclined or to various types of roof structure using Top-fix posts that are capable of being fixed to built-up or composite trapezoidal metal roof sheets, single ply membrane roof profiles, concrete roofs, lead lined roofs.

Based on an 8mm 7x7 stainless steel cable passing through intermediate cable guides and varying corner assemblies.

The cable is terminated at either end using hex swaged fork end or tensioner units connected to end anchorage assemblies.

All constructed from high grade stainless steel for longevity of life.

The systems are manufactured under the quality control standard ISO 9001 and in compliance with European standard EN795 class C

Various forms are available as follows:

Fixing to walls: Components are fastened direct to the fabric of the building using suitable anchors, for masonry or concrete structures, suitable resin anchors are installed and site pull tested to a force dependant on application. The system can be fitted at different levels subject to site requirements. The intermediate and corner assemblies are adaptable to suit different positions.

Overhead systems: Using special intermediate brackets the system can be fixed direct to the soffit. The shuttle device even with the use of fall arrest block will run freely over the intermediate and corner units. In-line shock absorber units as shown opposite reduce the resultant end loads in the event of a fall occurring to subsequently reduce the impact onto the main structure

Fixing to Steelworks: Components are fastened direct to the steelwork using bolted connections.Isolators are fitted between the components and the steelwork to avoid bimetallic reaction.

In-line shock absorbers are employed as deemed necessary to reduce resultant end loads.

Post fix systems (Roof top applications). Various types are available to suit specific site requirements, Posts are capable of absorbing a high proportion of the forces created n the event of a fall occurring, this allows the posts to be fitted to a wide variety of roof build-ups. For higher load requirements special energy absorbing posts are installed to further reduce resultant end loads.

Herewith are a few examples:

Trapezoidal Roof profiles: Post bases sits on-top of the crown of the roof sheet, fixed in position with Bulbtite Industrial rivets. To avoid further weather-sealing the underside of the post base includes a mastic sealing strip. Posts are compliant with European standard EN795 class A.

Standing seam Roof profiles:

Post bases are clamped ontop of the Standing seam profile using four alloy clamp assemblies that fasten carefully around the seam, again avoiding the need for penetration.

Posts are compliant with European standard EN795 class A

Single-ply membrane profile: Posts sit on-top of the single ply membrane, secured in position using four M8 studs that pass through the roof build-up either secured with toggle assemblies to the underside of the metal deck or plywood liner trays. Or using resin anchors into concrete sub structures.

Post bases have a special coating to allow direct bonding by the roofing contractor.

For non compatible coatings post bases the baseplate can be supplied in naked format, allowing the roofing contractor to dress over the base and up the post assembly in a similar method to sealing soil and vent pipes.
