Page 7: Mechanical Safety
2 MECHANICAL SAFETY Mechanical limits The K2 rigging system complies with 2006/42/EC: Machinery Directive. It has been designed following the guidelines of BGV-C1. 2006/42/EC: Machinery Directive specifies a safety factor of 4:1 against the rupture. The limits specified in the tables below correspond to deployments with a safety factor of 4:1 or higher. -
Page 8: Rigging System Description
K2 WST enclosure ® RIGGING MANUAL VERSION 1.0 3 RIGGING SYSTEM DESCRIPTION K2 enclosures can be ground-stacked and flown independently (K2-BUMP) or in combination with K1 system elements (K1, K1-SB, or K1-BUMP). The K2-BUMP is designed to be directly compatible with K1 and K1-SB. The K2 enclosure rigging system requires the K2-LINK interface to be compatible with the K1 rigging system. -
Page 9: Elements For Storage And Transportation
Elements for storage and transportation The K2-CHARIOT is designed for the transportation and storage of blocks of four K2 enclosures. During transportation the blocks must have an inter-enclosure angle of 10° to avoid any separation of the enclosures. This angle must be set using the enclosure rear rigging arm pin. The automatic locking system must remain unloaded. The K2-CHARIOT rear rigging arm must be at its -15°... -

Page 12: Elements For La-Rak Rigging
K2 WST enclosure ® RIGGING MANUAL VERSION 1.0 Elements for LA-RAK rigging The K2-RACKMOUNT is designed to stack one or two LA-RAK on top of a flown array. It is composed of four rails and a stabilizer. The rails are screwed on the K2-BUMP. Their number and position depend on the number of racks. The K2-RACKMOUNT must be used along with either one or two K2-BAR. - Page 13 When two racks are mounted side by side, the stabilizer is used to prevent the assembly from tipping or toppling over. The stabilizer traps one of the chains used to lift the assembly. 0° site angle 30° positive site angle Refer to APPENDIX A: PICKUP POINTS GUIDELINES for more information.
