BL-27100 BL-29900 BL-10300
ZGS-12000-9v1 Fixed Hoist Test Facility
1) Purpose
a. The purpose of the Fixed Hoist Test Facility (FHTF) is to allow the
operation, maintenance, and training of the operation and maintenance of
rescue hoists in use by the 160th SOAR without the need of an aircraft.
b. The FHTF works in conjunction with the ZGS-10000-5-2 mobile take up
assembly.
2) Scope
a. The FHTF provides provisions for the mechanical and electrical
attachments of three different rescue hoists.
i. BL-29900-xx
ii. BL-27100-xx
iii. BL-10300-151
b. The FHTF is intended to be used in conjunction with the ZGS-10000-5-2
Mobile Rescue Hoist Ground Equipment (RHGSE). The RHGSE has
been equipped with a work platform to enable working on the hoist while
in the operating position. This allows closer inspection of the hoist
mechanism, setting the limit switches and installing and removing the
rescue hoist cable.

c. The combined system allows operating the rescue hoists for the purpose
of setting limit switches, verifying correct setup of the hoist mechanisms,
changing the cable, and tensioning a new cable under load.
d. The FHTF is supplied with a hydraulic power supply that has been
designed to maintain the cleanliness of the hydraulic fluid used in the
hoist in order to prevent the contamination of the hydraulic system of the
aircraft.
The hydraulic power supply provides 3000 psi pressure at 6 GPM. The
system is equipped with a high pressure filter and a low pressure filter
and self sealing quick disconnects. The high pressure filter is rated to 5
Micron (abs) and has a clogging indicator. The low pressure filter is rated
is rated to 5 micron. The system also utilizes a contamination control
breather that removes moisture from the air and therefore keeps water
out of the hydraulic fluid. The hydraulic fluid used is the same as used in
the aircraft, Mil-H-83282.

e. The FHTF has been supplied with an onboard 24 Volt power supply to
provide power to the Mobile RHGSE in order to allow for continual
operations without having to stop and recharge the batteries on the
Mobile RHGSE
f. The FHTF has the mounting brackets, interconnect cables and hydraulic
lines and fittings to test all the hoists it has been designed to service.

3) Theory of Operation
a. The system is supplied with hoist adapters and a chain hoist that are
used to raise the hoist into position where two load cells attach and
support the weight of the hoist and adapter and the load applied by the
Mobile RHGSE.

b. The system is equipped with quick disconnects and electrical connector
and cables to attach the three types of hoists. The mounting bracket
moves with the hoist mount, therefor eliminating the possibility of damage
to the cable or connectors if they are not disconnected before lowering or
raising the mount.
c. The system is equipped with a 28 volt 5 amp
power supply to provide control power to the two
control boxes that operate the BL-27100 and the
BL-29900 hoists.
d. The system includes the means to mount the
control box for the BL-27100, and the pilot
control box and the pilot control box for the
BL-29900.
28 VDC power supply is inside
the control box.

e. The system is equipped with a proportional control valve and a joystick
controller to operate the BL-10300 hoist.
f. The system is equipped with a MS90362-1 receptacle to accept the plug
that delivers 115 V 3 phase 400 hz power to the BL-29900 hoist and the
BL-27100 hoist fan.

g. The system is equipped with a 30 Amp 3 phase breaker to protect the
BL-29900 and the equipment wiring in the event of a hoist malfunction.
h. The system is equipped with three 2 amp circuit breakers in the event the
three phase fan on the BL-27100 is to be operated. If the fan has a
problem with one of its windings the breakers will protect the fan and the
wiring from further damage.
i. The system is equipped with an hour meter that operates when ever the
load display is on.
j. All the pins that are used to attach the various components are tethered
to the component so they are not easily lost
k. The system is also equipped with a 24 volt power supply to provide power
to the ZGS-10000-5-2 mobile take up while in use with the Fixed Hoist
Test facility.
