Safety Checklist Items

Control System - Failsafe PTO switch on radio control unit Safe-Stop button Limit movement within safe envelope via software Dual processors Dual encoders Double brakes – engage with power loss Cable tension limits via sensors & software

Collision Avoidance Power-on beacon Contact sensor Two-way radios Spotter on floor

26

Safety Checklist Items (continued)

Safe escape and rescue Controlled descent device Secondary Radio Control Unit on the floor

Fall protection Handrails Personal Fall Arrest System (PFAS) Anti-slip surface on platform floor

Fire extinguisher AMP wiring complies with codes Load tests – 3 times rated load Warning labels

27

Safety Procedures

User manual – operations & maintenance Training and certification of operators Use of primary and secondary radio control units

Override by secondary unit – keep in secure area

Role of Spotter. Use of control descent device Use of PFAS
