    K2 WST enclosure ® RIGGING MANUAL VERSION 3.0 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 a safety factor of 4:1 or higher for flown deployments.

  • Page 9: Assessing Mechanical Safety

    Assessing mechanical safety In order to assess the actual safety of any array configuration before implementation, refer to the following warnings: Rated working load limit (WLL) is not enough The rated WLL is an indication of the element resistance to tensile stress. For complex mechanical systems such as loudspeaker arrays, WLLs cannot be used per se to determine the maximum number of enclosures within an array or to assess the safety of a specific array configuration.

    K2 WST enclosure ® RIGGING MANUAL VERSION 3.0 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.

    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°...
