This new secondary guarding system is designed to encourage boom lift operators to attach their harness lanyards to established platform anchor points. It comes in “Alert” and “Advanced” configurations and is comparable to the automotive industry's universal adoption of seatbelt in-use while driving warning systems. Designed for affordability, easy installation and quality, this device is easy for fleets to incorporate, whether large or small, so that it is available to everyone. It can be purchased both as a factory-fit option or as an aftermarket kit, retrofitted to all Genie boom models manufactured as of 2003 and is compatible with industry’s most popular lanyard carabiners (clips). The aftermarket kit can be retrofitted to existing models with basic tools in just under 15 minutes and without altering the machine - simplifying service work and fleet management.
