Ronstan S22 Safety Rail System — User Instructions

Certification & System

• Certified to EN795:2012 Type D (anchor devices), CEN/TS16415:2013 Type D (anchor devices for more than one person simultaneously) and AS1891.2:2001 (horizontal lifeline and rail systems). Testing is witnessed by a Recognised Organisation, member of IACS.
• For use with personal protection equipment to protect against falls from a height, such as when working outside conventional guardrails for cleaning and maintenance. Not for lifting equipment or any other purpose.
• Up to three persons simultaneously, one dedicated car (single or tandem) per user. Each harness or device must be secured to a separate attachment point.
• Fall arrest use: the user must have a means of limiting the maximum dynamic force during arrest of a fall to 6kN.
• "Rope access" use (EN363), where the user's weight is supported by the anchor device: a dedicated tandem car with separate attachment points for the working line and the fall arrest safety line, plus a suitable fall arrester and harness, for each user. "Restraint" or "Fall arrest" use: a single car may be used.
• Track rail: plunger stop holes at 50mm centres, mounting holes at 100mm. On standard rails the last mounting hole is 48mm from each end; on rails cut to length on site, no more than 50mm.
• Marine grade anodised aluminium cars, rails and end stops; recirculating Torlon® ball bearings; Grade 316 forged stainless steel pivoting shackles; rubber buffers; spring-loaded stainless plunger with elliptical knob that can be locked disengaged.

System Components

Additional sliding cars for tools or equipment connect to the RCC22-2A tandem car with the RCC22-5 connector plate. The RC12281PS cover plate fits the RC12281S end stop to conceal the end of the track.

Installation

• Installed only by competent persons or organisations, and verified by calculation and post-installation testing.
• Track rail: 6mm countersunk Grade 316 stainless fasteners at 100mm centres, minimum tensile strength 700MPa. M6 hexagon socket countersunk A4-70 DIN7991 screws recommended, torque no more than 7.1Nm. End stops also use 6mm countersunk Grade 316 stainless fasteners.
• Longer runs: use more than one rail and trim to length, never exceeding 100mm between mounting fasteners (across a join of standard rails the spacing is 96mm). Joining insert RC1221J aids alignment.
• Mount so the cars travel in a horizontal plane (parallel to the water plane) within ±5°; the rail itself may be on a vertical plane (0°), horizontal plane (90°) or an incline between.
• Maximum loads transmitted to the structure: Fy = 12kN, moment M = 266.4Nm (22.2mm dimension shown on the load diagram). The structure and fasteners must not fail at these loads; isolate the fastener from the structure where needed to prevent corrosion.
• Cars come with ball bearings fitted, on a short loading track rail: remove the RC12281S end stop, butt the loading rail end-to-end against the installed rail, slide the car across and refit the end stop. Do not discard the loading rail.
• If a car cannot pass a discontinuity, a second car must be available after it: the user must always be attached to at least one car.
• On multi-user systems, display the RCC22-ID plate at the user entry point(s), typically next to an end stop.

Testing & Use

• Post-installation test before first use: 6kN on a single car for at least 15 seconds at each extremity and near the midpoint (on multi-rail systems, near the midpoint and at least one rail join). Then inspect per the annual procedure and record the results (Appendix A and B of the instructions).
• Periodic test: the same 6kN / 15 second test, repeated for each car on a multi-user system, at intervals of not more than five years in the absence of other regulations.
• Use only by trained, competent persons with approved personal protective equipment, and with a rescue plan in place.
• Disengage the plunger only while changing position; once in position, re-engage it to hold the car.
