5. NJ Bambi 2014 Torrentula Operations and Service Manual version C 8 ET Section 3 Deploying the Bambi Bucket Procedures and Calculations Important Note To avoid potential rotor strikes when using the Bambi bucket the operator must measure the extended length of the Bambi bucket and the distance from the belly hook to the closest possible point of the tail rotor A Always measure the overall extended length of your Bambi bucket And B Measure the distance from the belly hook to the closest possible point on the tail rotor B must always exceed A by at least six 6 inches Instant Deployment System IDS The Instant Deployment System IDS uses a hub and spoke mechanism to automatically expand the mouth of the bucket as soon as the suspension cables take the weight of the Bambi Caution Operating the Torrentula valve with the bucket collapsed may cause damage to the valve and or control head If the valve must be operated on the ground please refer to an important note on page 2 of this manual When the bucket is full the IDS Deployment Cable and hub Restrainer Cables should be slack they should not bear any load Their function is to position the hub and spoke mechanism to hold the bucket open The main parts of the IDS are illustrated in the parts section of this manual To deploy the IDS System on the ground reach into the bucket grasp the hub of the IDS and pull outward fully until the two cables from
6. Section 9 PowerFill System System Components The PowerFill Torrentula system is comprised of a set of electrically driven high efficiency pumps mounted within the confines of the valve structure on a Torrentula valve equipped Bambi bucket The pumps can fill the bucket rapidly and completely in shallow water sources as low as 21 0 53 m deep The system consists of the following main components Two or four depending on model 28 volt DC driven pumps Multi conductor wiring and breakaway plugs Electrical junction box Applicable Bucket Models Bucket models 4453 through 7590 receive a two pump system while the larger size buckets HL4000 through HL9800 receive four pumps The optimal pumping rate for each pump is 400 to 450 GPM 25 28 L sec Configuration Each system is supplied with a bottom stand off that supports the bucket and helps to maintain flow into the pump intakes when the bucket is resting on the bottom of the water source To prevent damage to the pump impellers each system has large area filter screens mounted inside the valve structure Each pump is equipped with a low restriction one way valve to prevent back flow through the pumps when they are not running The PowerFill Torrentula system comes complete with all the required electrical equipment and wire leads for operation of the pumps Bambi 2014 Torrentula Operations and Service Manual version C 16 Section 9 PowerFill System Syst

C 14 ET Section 8 Landing Landing Procedures Section 8 Landing Landing Procedures The recommended landing procedure is to allow the bucket to touch down ahead of the helicopter and then maintain tension on the suspension lines by backing up slightly thereby keeping the control head at an angle while landing Do not release the control head from the cargo hook while hovering This could damage the control head If the control head must be released while hovering have ground personnel support the control head before releasing Do not drag the Bambi over rough surfaces when landing or ground handling or land at high speeds This may damage the bucket shell Torrentula valve and the control head Caution To avoid damage to helicopters with low skids never land on a vertical control head This could damage the helicopter and or the control head The head is approximately 24 610mm in length Caution If the control head has experienced a severe impact it is necessary to visually examine all three shackle bosses on the control head base to determine if they have been bent or otherwise damaged If any of the shackle bosses have been damaged the control head base requires replacement Operating with a damaged control head base casting could result in failure and unintentional release of the bucket m Bambi 2014 Torrentula Operations and Service Manual version C 15 ET Section 9 PowerFill System System Components
