  • Page 22 ESSENTIAL ARACHNIPOD CONFIGURATIONS Bridge assembly An Arachnipod Bridge (Figure 32) is used for spanning larger openings or voids where a regular tripod, A-Frame or quadpod would not be able to. These include trenches, large holes, mine and lift shafts. Bridge beams are available in lengths of 2m, 3m and 4m.

  • Page 29: Principles Of Edge Management

    Edge Management is the assessment of the rigging tasks and equipment required to safely manoeuvre a load over an edge. A high change of direction is the key to successful edge management (Figure 48, 49) and the Arachnipod is an exceptionally versatile tool to facilitate this solution.
  • Page 30 (Figure 53), the rope would remain stationary because the load forces are equal and no movement would occur. If an Arachnipod is placed under this rope, the same rules would apply. However, because there is a change of direction in the rope, a resultant force now exists (Figure 54).
  • Page 31 Anchor selection and anchor rigging techniques are not within the scope of this manual. Using an Arachnipod leg as an anchor The Arachnipod Equipment Bracket may be used as a rated attachment point. It is designed and tested for attachment to the middle leg section.

  • Page 32: Stabilising The Arachnipod

    ESSENTIALS: STABILISING ARACHNIPOD 5 - STABILISING THE ARACHNIPOD Stabilising the Arachnipod Additional rigging may be required to stabilise the Arachnipod. The purpose is to manage sideways forces (e.g. change of direction) or other situations where the Arachnipod may become unstable.
  • Page 33 ESSENTIALS: STABILISING ARACHNIPOD Lazy Leg TRIPOD STABILISATION A Lazy Leg or easel leg tripod is similar to a regular tripod because it uses three legs in compression. A Lazy Leg tripod is constructed as an A-frame, utilising a Lazy leg as the third leg.
  • Page 34 Figure 63 the resultant below the load is directly contributing to the stability of the bridge. A Bridge Ratchet Strap Kit, customised for convenient use with the Arachnipod, is available for stabilising the bridge system. A-FRAME STABILISATION An A-Frame makes use of two legs to form two compression members.
  • Page 35 ESSENTIALS: STABILISING ARACHNIPOD SIDEWAYS A-FRAME STABILISATION (Figure 66) This configuration has two legs positioned close to parallel with the load line. The leg lengths and positions are set so the resultant is focused between the two legs but not in direct alignment with the legs.

    INSPECTION & MAINTENANCE ARACHNIPOD KIT RECORDS Each Arachnipod Kit is assigned a Kit Number. This is one collective number recorded on Ferno Australia’s database, which references all individual serial numbers contained within the Arachnipod Kit. A kit contains more than one item with a serial number. It can range from a tripod, or a tripod plus accessories to a full Total Edge Management System (TEMS) Kit.

  • Page 48: Form: Regular And Annual Inspection Record

    The unit must be inspected before and after every use by the competent person/s using the equipment. • Additionally, the Arachnipod must be inspected by a competent, instructed, accredited person at least once a year to ensure the unit is fully functional. Details of this annual inspection should be recorded using the Inspection Record Form below.
