Level 37, 680 George Street, Sydney NSW 2000 Australia CE CEC40142A1 Certified in 3 & 4 leg configurations to CEN/TS 16415:2013 for maximum 2 persons and EN 795:2012 for single person use Ferno is represented throughout the European Union by: Ferno (UK) Limited Ferno House, Stubs Beck Lane,...
Ferno knows that rigging is not always conducted on a flat surface or with a clean edge so the Arachnipod was designed with every conceivable task in mind. From the harshest vertical rescue conditions to a simple tripod for a confined space entry task, the Arachnipod will provide the flexibility that end users demand.
• The Arachnipod and associated hardware must always be secured to prevent it from falling over an edge. The Arachnipod may become unstable if used without an assessment of the resultant force and direction.
The weight of a rescue load typically ranges from 200 kg to 280 kg (440 lb to 617 lb) depending upon a number of factors. The Arachnipod offers many configurations that match or exceed the 280 kg load with only a few exceptions.
When the Arachnipod is used as part of a fall arrest system, the user shall be equipped with a means of limiting the maximum dynamic forces exerted on the user during the arrest of a fall to a maximum of 6kN.
The maximum life span of the Arachnipod is twelve (12) years from first being put into service provided it has not sustained damage, is maintained, serviced and inspected according to manufacturer’s instructions. Arachnipod components are labelled with the Date of Manufacture.
Do not use your Arachnipod if any parts are missing. The Arachnipod must not be used outside its limitations, or for any purpose other than that for which it is intended.

Edge management is the assessment of the rigging task to ensure that the load can be manoeuvred over the edge. Rigging to provide a high change of direction is the key to successfully managing an edge. The Arachnipod is a tool that can be used to achieve a high change of direction.
The Arachnipod if used correctly will provide an efficient and safe edge management system but not all aspects of the rigging and equipment use can be guaranteed by the manufacturer.
Edge Protection The Arachnipod can be rigged with the main line passing over the pulley head and a rated hauling system can be used to progressively pick the safety line up as the load is raised. This process provides additional protection against a main line failure.
Understanding the forces being applied to the Arachnipod The Arachnipod or any other edge management device is subjected to resultant forces and directions. To keep edge management devices or rigging in place the resultant forces and directions being applied must be assessed and sometimes additional rigging will be required to provide stabilisation.
Australia Assessing the stability of your Arachnipod rigging The following stabilisation examples will look at the resultant directions and suggest how the stability of the edge management scenario may be managed. Remember: an applied force has magnitude and direction. This manual will refer to resultant forces and resultant directions.

The Attachment Point Attachment point connected joint looks much like a hinge. (D-shackle) for additional legs A basic tripod is made up of three standard legs Rated load joined with Qik-link pins.
Rigging Plate A rigging plate is used when two legs are connected as an A-frame. It is used to provide additional stabilisation attachment points and is not for live loads. Arachnipod User Manual Version 6.1 DOC ID: 00184-AU-V06 (2015/03)
The foot locating spike lines up with one of the holes in a standard foot. Taking care not to impact against the Arachnipod foot or leg, hammer the hold down stake half way into the ground. Check the alignment of the foot locating spike then continue to hammer the stake into the ground.
Australia Equipment Bracket The equipment bracket must only be used when attached to the middle telescopic leg section. The WLL of the Arachnipod is reduced to 220 kg when a leg is used as an anchor. Leg pins Attachment point...
• The rigging experience of the user It is recommended that two or more people work together to assemble the Arachnipod components as follows: Step 1. Preparation Select the most appropriate Arachnipod configuration for the task. Establish a staging area where the Arachnipod components can be laid out.

Arachnipod User Manual Version 6.0 Bring the remaining head joints together and fit the last Qik-link pin. Check all Qik-link pins to ensure that they are 120° fully engaged into the head joints. Push down 120° 120° until they are retained by the spring clip.

Once desired height is achieved, fit leg pins through leg pin holes. It may be necessary to adjust some or all legs at different heights to suit the terrain. Ferno does not place a limit on the amount of differential adjustment between each leg.

Step 7. Assess the resultant force and direction Tension and pre-load lines may need to be rigged to ensure Arachnipod stability. Please read the section in this manual titled “Assessing the stability of your Arachnipod rigging”. Using hand tension, a simulated force can be applied by to the main line to visualise the resultant direction.
Using an Arachnipod leg as an anchor The Arachnipod equipment bracket can be used to provide a rated attachment point that connects to a leg of the Arachnipod. Anchoring to a leg is useful in many situations including tripod applications. The WLL is reduced to 220kg when a leg is used as an anchor.
Arachnipod User Manual Version 6.0 Tripod Stabilisation This tripod application does not require any additional rigging because the resultant force and direction is within the triangular base. The dotted lines on the ground surface represent the point where the resultant direction is focused.
The length and position of the lazy leg may be adjusted to assist with the management of the resultant direction. The dotted lines on the ground surface represent the point where the resultant direction is focused. Arachnipod User Manual Version 6.1 DOC ID: 00184-AU-V06 (2015/03)
Arachnipod User Manual Version 6.0 Quadpod Stabilisation The Quadpod allows for greater versatility and stability combining 4 legs into one system. A Quad Plate is required to ensure stability of the entire system. The principles of stabilisation are the same as a Tripod with the addition of an extra leg.
An A-frame makes use of two legs to form two compression members. A-frames always require rigging to provide at least one tension member, additional rigging can be used to provide two or more tensioned members and pre-load rigging can be used to hold the A-frame in position. A-frames can be constructed with Arachnipod components using three methods: Method 1 Standard A-frame Two legs positioned perpendicular to the load line.
Page 31
(front elevation). The SA-frame should be laid over, tilted or offset slightly for the following two reasons: 1. To provide clearance so that the main line does not contact the Arachnipod components, and 2. To ensure that the rigging is clearly identified as being “tension rigging” and “preload rigging”...
This method is ideal when there are no anchors available for pre-loading on the low side of the A-frame. This leg may also be lashed, bolted or fixed to a secure object Arachnipod User Manual Version 6.1 DOC ID: 00184-AU-V06 (2015/03)
A gin pole is positioned and rigged so that the resultant forces are being applied close to the long axis of the single leg with a slight offset for two reasons: 1. To provide clearance so that the main line does not contact the Arachnipod leg, and 2. To ensure that the tension and pre-load rigging is clearly identified The tension rigging keeps the gin pole in position and balances out any resultant forces created by the slight offset nd the preload rigging keeps the gin pole in position.
Leg securing ropes or round lashing can be used to provide tension rigging that keeps the single leg in place. Square lashing can be used to secure the leg to the hand rail. Arachnipod User Manual Version 6.1 DOC ID: 00184-AU-V06 (2015/03)
