Application

Latchways Cable Based Engineered Fall Protection System; used in the Construction Industry to allow operatives to work safely at height. All in conjunction with the latest Global standards.

The system has been developed alongside major Roofing manufacturers to ensure that warranties and guarantees are not affected.

Description

Guided type fall arrest system using a cable attached to Constant Force® anchor posts. Provides individual protection, requiring direct action by each user to ensure they are protected. Must be used with personal protective equipment (PPE), e.g. full body harness to BS EN 361, energy absorber to BS EN 355, and lanyard (of correct length) to BS EN 354. PPE procurement is normally the responsibility of the building owner/ user.


The level of user competency required to safely use different categories of system varies:

  • Perimeter system: Fall restraint; no PPE adjustment necessary; basic user training required.
  • Perimeter system with fall hazards in addition to roof edge (weak rooflights, vents, etc): Fall arrest; no PPE adjustment necessary; basic user training required.
  • Ridge system: Fall arrest; PPE adjustment necessary; advanced user training required. Not advised for roof pitch greater than 25°.

Note that perimeter systems generally do not give blanket coverage of a roof. If this is required, and a ridge system is deemed impractical/ unsuitable, then a series of interconnected systems must be installed, covering the full width of the roof.


Components are designed for compatibility with most roofing systems; Latchways technical literature gives specification details for the following:

Latchways® systems can be retrofitted to existing buildings.


Product options:

Finish to Constant Force® posts:

Polyester powder coating can be matched to roofing panels, if required.

D ring and hanger:

Attaches to intermediate CF post to form intermediate cable support.

90° Corner bracket:

One piece bracket; attaches to intermediate CF post to provide change of direction.

Variable bracket:

Attaches to intermediate CF post to provide angle change of between 0° and 80° in horizontal or vertical plane.

ClimbLatch™ attachment:

Required for inclined sections if roof pitch is greater than 15°.


Features and benefits:

  • Anchorage device: 7 x 7 stainless steel cable, grade 1.4401 (316S), to BS MA 29.
  • Turnbuckle, swage and clevis assemblies: Provide methods of terminating cable at ends of system. Turnbuckle incorporates a tension indicator, which spins freely when the system is correctly tensioned.
  • Transfastener: Connects system user to anchorage cable. Passes through intermediate cable supports without need to detach and re-attach, allowing smooth, hands-free operation. Made from stainless steel, grades 1.4401 (316S) and 17/4 PH.

Specification data - Guided type fall arrest systems

System performance

Design of anchor device fixing points

Guidance for specification option:

Extremity or corner post (CFp Type 2) includes an integral 316 (1.4401) grade stainless steel energy absorbing coil and roller mechanism. This enables the coil and body assembly to deploy in a predictable manner, in any direction and at a controlled rate.

Each intermediate post (INT) includes an integral 316 (1.4401) grade stainless steel mechanism that enables the post body assembly to deploy in a predictable manner and in any direction.

Pre-installation survey

Survey to be carried out by a Registered MSA Latchways Installer.

Structural anchors

Constant Force® post.

Guidance for specification option:

  • Integral, stainless steel, energy absorbing coil ensures that, in the event of a fall, load transferred to roof cladding does not exceed 10 kN.
  • Dome: Marine grade stainless steel; Collar and base plates: Zinc coated carbon steel.
  • Each post carries a unique serial number to ensure traceability.
