4.12.16 Preparation for Littered Patient Loading.
Use the litter lift controls on the overhead control panel or the side control panel for the following procedures.
1. Simultaneously, press and hold the LOWER PLATFORM, FWD and AFT controls to the DOWN position. The lower litter platform moves down. Hold the switches until the plat-form stops moving, releasing and pressing the FWD or AFT switches as necessary to ensure the platform maintains a level position. The platform should stop about 3 inches above the .oor.
2. Simultaneously, press and hold the UPPER PLATFORM, FWD and AFT controls to the DOWN position until upper platform moves down to the desired level. Press and release the FWD or AFT switches as necessary to ensure the platform maintains a level position while moving.
4.12.17 Litter Lift System Patient Loading and Un-loading.
To prevent patient injury or death, or damage to equipment or cargo, ensure the patients platforms do not come in contact with the patient, each other, cargo, or the aircraft.
Do not operate the litter lift mechanism continuously for more than one minute or damage to drive mechanism may occur.
Patient restraints are secured prior to loading the heli-copter. Up to a maximum of four patients can be carried on the platforms. To load litter patients:
4.12.17.1 Load First Patient.
1.
AUX SW panel MED INT switch -ON.
2.
All four cabin medical control panel EMER-GENCY STOP switches placed -RUN.
3.
Ensure associated medical station control panel SEAT OVERRIDE switch -ON.
4.
Position and secure the .rst patient on the litter platform using the platform restraint belts. If injuries permit, the belt closest to the head is placed under the arms and over the chest and
tightened. The other two belts are placed over the entire body and tightened.
NOTE
EMERGENCY STOP switches are pro-vided on each control panel to stop lift mo-tion if necessary. To stop all lifts from oper-ating, place any of the four EMERGENCY STOP switches to the STOP position. To resume lift operations, pull the switch out-wards, past the raised notch and move it up to the RUN position.
5.
Simultaneously, press the UPPER PLAT-FORM, FWD and AFT controls to the UP po-sition. The upper litter platform moves up.
6.
As the platform approaches the desired .ight position, release the switches. The platform stops. For three patient con.gurations, use the upper lift positioning reference mark on the side control panel to determine approximate posi-tion of the top patient. (Figure 4-23).
7.
Use individual FWD or AFT controls to adjust the platform to the necessary tilt being careful to avoid patient to aircraft contact.
4.12.17.2 Load Second Patient.
1.
Position and secure the second patient on the litter platform using the platform restraint belts.
2.
Simultaneously, press the LOWER PLAT-FORM, FWD and AFT controls to the UP po-sition.
3.
As the platform approaches the desired .ight position, release the switches. The platform stops. For three patient con.gurations, use the lower lift positioning reference mark on the side control panel to determine approximate posi-tion of the middle patient. (Figure 4-23).
