1.5 DESIGN CRITERIA

Assemblies allow users to walk the entire length of rail uninterrupted and provide secure anchorage to arrest a fall. Users have freedom of movement and carriages run unhindered. Assemblies can be mounted to floors, walls or ceilings and accommodate multiple users as dictated by delegated design. Users have continuous hands free access for performing tasks.

Withstand the effects of loads and stresses described in ANSI Z359.6 and OSHA 1926.502. Calculations account for dynamic loads, impact factors and assembly inertia forces.

Determine fall arrest loads for two workers. Each worker, including tools and material carried, weighs 310 pounds. Connection devices provide a maximum arresting force of 900 pounds. Incorporate a safety factor of 2.0 in calculations. The maximum load presumes that both workers are connected to a common assembly and fall simultaneously. A third worker may be added that is connected to an assembly serving a separate area.

Select combinations of rails, anchors, harnesses, lanyards and cables meeting or exceeding the maximum arresting force dictated by delegated design.

1.6 WARRANTY

Furnish the standard 10 year warranty of the manufacturer. Coverage is to ensure that fall protection assembly finishes do not corrode, peel, chip, crack, blister or chalk.

PART 2 MATERIALS

2.1 ROOF RAIL ASSEMBLIES

2.1.1 Description

Horizontal rail assemblies include attachment carriages, attachment plates, joints, corners, system stops, rails, carriage stops, specialty components and similar items. Rails withstand 2,700 pounds of force maximum, and calculations are adjusted to accommodate no more than the maximum arresting force of user harness, lanyard and attaching cable.

SECTION 11 81 00 Page 3

2.1.2 Components

Low profile rails are 1.25 inch by 1.25 inch aluminum extrusions.

Concealed rail connectors are 2.11 inch by 6.06 inch aluminum extrusions and supported with 7.87 inch armatures attached to substrates. Side fixed connectors are similar and also function as an anchor without any additional support. Connectors comply with OSHA 1926.502. Corners and bends have 90 degree and 45 degree configurations. Curves are available up to a radius of 7.87 inches. System stops prevent rails from disengaging end brackets. Molded ends protect exposed edges at rail terminations. Tamperproof carriage stops prevent carriages from disengaging rails. Removable carriage stops prevent carriages from disengaging rails, however, can be removed to replace carriages.

Attachment carriages are aluminum with a tensile strength of 3,372 pounds and glide on aluminum, nylon coated wheels. A stainless steel shackle with carabiner hook creates a pivot that enables cable connection at any angle. Provide signage and identification tags.

2.1.3 Attachments

Rail fixing attachments are components fabricated from aluminum and stainless steel. End anchors secure rail terminations to the structure and control rail movement in the event of a fall. Intermediate anchors secure rails to the structure at intervals that suit the substrate of attachment. Concealed end anchors secure rail terminations to the structure and control rail movement in the event of a fall. Concealed intermediate anchors secure rails to the structure at intervals that suit the substrate of attachment.

2.1.4 Steel

Fabricated supports are carbon steel with a corrosion resistant finish.

Plates, shapes and bars conform to ASTM A36/A36M. Tubes are cold formed and conform to ASTM A500/A500M . Welding rods and bare electrodes are selected according to AWS specifications for metal alloys encountered.
