Safety Cages are typically made from galvanized steel, stainless steel, or aluminum alloy, as listed in the product specifications. The choice depends on the application environment and required corrosion resistance.
According to ISO 14122-4, typical parameters include ladder width of 400–600 mm, cage diameter of 700–800 mm, cage height of 2000–3000 mm, vertical bar spacing of 250–300 mm, and horizontal hoop spacing of 1200–1500 mm. These are reference ranges; exact dimensions must be confirmed with the supplier.
The cage surrounds the climber, providing a physical barrier. If a slip occurs, the climber can grasp the hoops or rails to arrest the fall. It is a passive system that does not require active engagement.
Safety Cages are referenced in standards such as OSHA 1910.27, ANSI A14.3, and ISO 14122-4. These standards specify dimensional and performance requirements. Compliance should be verified with the manufacturer.
