JOMY Cage ladders or Caged ladders are permanent ladders with a safety cage. This JOMY safety cage can be composed of complete hoops, 3/4 hoops or 1/2 hoops.
According to standard ISO 14122-4 (machinery access), a safety cage is required for ladders above 3m (except when a lifeline is used). The safety cage has to provide a free diameter at a minimum of 65cm and a maximum of 80cm.
Each JOMY safety cage is composed of five round cage uprights at 18mm, which pass centrally through the hoops with square section of 25mm. The free diameter within the hoops is 70cm. The vertical distance between the hoops can be fixed freely according to required specifications. It is recommended to limit this vertical distance to a maximum of 1m.
A JOMY permanent cage ladders in one piece cannot be longer than 10m according to standard ISO 14122-4 (machinery access). Longer JOMY ladders must be composed of multiple fights, each at a maximum of 6m. The user can switch from one flight to the next via rest-landings. On these landings JOMY provides double cages.
JOMY makes the cages also according American OSHA rules including the flared openings. These are ready available in our warehouse in the U.S.A..
