3.1 Attaching to Cargo Hook
The Bambi Bucket is rigged for a lateral cargo hook.
Correct attachment is indicated when the name plate on
the control head faces forward in flight; this ensures that
the ballast on the Bambi will face forward in flight.
CAUTION: It is IMPORTANT that the ballast faces
forward In flight. This will avoid twisting of the
suspension lines and possible jamming of the
trip line.*
There are two different styles of control head used on the
Bambi Bucket. The head used on Models 6072-4453
has a moveable yoke which can be rotated by 90 degrees.
The yoke is machined to orient in either direction.
If your helicopter has a longitudinal hook, rotate the
shackle yoke unit at the top of the head by 90 degrees.
This will place the name plate on the control head forward
in flight.
The head used on Models 5566-HL9800 is rigged for a
lateral cargo hook. It has a fixed top shackle. If your
helicopter has a longitudinal hook, use a second shackle
attached to the head shackle. This will effectively rotate
the attachment point by 90 degrees.
CAUTION: If using a second shackle on Models
HL5000-HL9800, it must have a load rating
equivalent to the top shackle supplied with the
head. Using a shackle with a lower load rating
could result in a shackle failure.
For either style of head, if using a swivel hook, operate in
the locked position to assure that the ballast is always
facing forward in flight.*
Caution: The Bambi Bucket may not be suitable
for a direct hook-up to the cargo hook. The
actual hook-up will be different for various
aircraft, and operators must comply to all
instructions and bulletins supplied by the
aircraft manufacturer. It is the operator's
responsibility to ensure that the Bambi Bucket
is correctly fitted to the helicopter.
3. DEPLOYING THE BAMBI BUCKET
3.2 Connecting Power
NOTE: To operate the solenoid and release the
water use a momentary contact switch rated only for
5.5 amps at 24 VDC. A suitable switch is available from
SEI. Alternatively, a lower rated switch may be used
with a relay--see suggested wiring diagram Section 17.
The solenoid has a 10% duty cycle. This means it is not
intended to be operated more than 10% of the time.
Operating the solenoid continuously will result in solenoid
failure.
The control head of the Bambi Bucket comes equipped
with a short length of two wire electrical cable. A popular
wiring hookup involves fitting a common household plug
to the end of the cable. To complete the wiring hookup:
1. Connect a 110 volt household plug to the wire
supplied on the control head.
2. Make a 12 AWG or heavier two wire interconnecting
electrical cable long enough to run from the bucket cable
to the accessory plug on the belly of the helicopter (leave
enough length for the control head to swing freely).
3. Attach the mating household plug to one end of the
interconnecting cable.
4. To check for continuity in the connections, push the
momentary contact switch. A clicking sound should be
heard from the control head.
5. With the engine running, test for a minimum of 24 VDC
at the breakaway plug (12 volts for 6072). If the voltage
is lower than 24 volts, use a heavier gauge wire for the
interconnecting cable. Re-test to confirm a minimum of
24 VDC at the breakaway plug.
The purpose of the household plugs is to offer a clean
“breakaway” if the Bambi Bucket has to be jettisoned
from the aircraft in an emergency. It is suggested that
the household plugs be lightly taped together with vinyl
tape while in use to ensure that wind action does not
separate the plugs. Current draw is only 5.5 amps. (24/
28 VDC)or 5.0 amps for 6072 (12-14 VDC).
*EXCEPTION: If you are using a swivel with an electri-
cal connection, then it is acceptable for the bucket to
be flown without the ballast facing forward. The Bambi
Bucket has been tested with the Canam Aerospace
swivel, and performs very well despite rotating in flight.
The swivel also prevents the suspension lines from
twisting up after dipping the bucket.
