CHAPTER 3

PREPARATION FOR USE AND SHIPMENT

3-1. PREPARATION FOR USE.

3-2. The following procedures need to be followed to ensure proper use of the aircraft engine lift trailer.

c If proper tiedown points were not used during shipment the equipment may be damaged and should not be accepted.

1. Verify that the proper tiedown points were used during shipment. See Figure 3-1.

2. Remove two cargo straps, one forward and one aft, securing the I-beam cradle assembly to the positioning frame.

3. Open storage box (25, Figure 4-4, Sheet 1).

4. Remove control pendants (Figure 4-10) from storage box (25, Figure 4-4, Sheet 1).

5. Close storage box (25).

NOTE

There is an alternate remote hook up point for the control pendant on the lower left forward frame.

6. Connect control pendant (Figure 4-10) to main con-nector on junction box (26, Figure 4-4, Sheet 1).

7. Connect second control pendant (Figure 4-10) to remote connector on junction box (26, Figure 4-4, Sheet 1).

8. Perform power up procedures. Refer to paragraph 4-91.

9. Perform power down procedures. Refer to paragraph 4-93.

w

• The MB-2/U30 tow vehicles are the only au-thorized tow vehicles for towing the lift trailer on flat surfaces and up to 15% slopes. The bobtail vehicle shall only be used for towing on flat surfaces and up to 3% slopes. When these vehicles are not available, (refer to Table 3-1) Towing Force Calculations for Engine Trailer Towing Vehicle to determine an equivalent vehicle. Failure to comply could cause injury to personnel or damage to equipment.

• The MB-4 tow vehicle shall not be used for towing of the lift trailer until completion of TCTO 35D3-3-79-511 is complied with on that specific lift trailer due to the dynamic braking and hard stops of this vehicle. Failure to comply could cause injury to personnel or damage to equipment.

• Forklift type vehicles with clevis drop pin shall not be used for towing of the lift trailer. Failure to comply could cause injury to personnel or damage to equipment.

10. Remove the lift trailer from the transport vehicle.

3-3. PREPARATION FOR TOWING AND

SHIPMENT (AIR/GROUND).

3-4. Prepare equipment for shipment in accordance with TO 35-1-4 and as follows:

w

• The MB-2/U30 tow vehicles are the only au-thorized tow vehicles for towing the lift trailer on flat surfaces and up to 15% slopes. The bobtail vehicle shall only be used for towing on flat surfaces and up to 3% slopes. When these vehicles are not available, (refer to Table 3-1) Towing Force Calculations for Engine Trailer Towing Vehicle to determine an equivalent vehicle. Failure to comply could cause injury to personnel or damage to equipment.

• The MB-4 tow vehicle shall not be used for towing of the lift trailer until completion of TCTO 35D3-3-79-511 is complied with on that specific lift trailer due to the dynamic braking and hard stops of this vehicle. Failure to comply could cause injury to personnel or damage to equipment.

• Forklift type vehicles with clevis drop pin shall not be used for towing of the lift trailer. Failure to comply could cause injury to personnel or damage to equipment.

c

• For transportation by air or truck, stabilizing foot pad assemblies must be positioned to remove most of the lift trailer weight from the tires. Tires must be in contact with the ground at all times. Failure to comply may cause damage to equipment.

• Remove the tow bar from the steering assembly if it cannot be stored in its lowered or raised position in front of the lift trailer. This opera-tion is required for all truck and air transporta-tion. Failure to comply may cause damage to equipment.

• Two cargo straps, one forward and one aft, shall be used to secure the I-beam cradle assembly to the positioning frame to support the 2 “G” up requirements. Failure to comply may result in damage to equipment.

• The engine lift trailer assembly requires a special drive on “low boy” (Figure 3-3) tractor trailer with removable goose neck adaptor which allows the air ride flatbed to be lowered within inches of the ground for loading. Failure to comply may result in damage to equipment

NOTE

For towing operations, follow steps 1 thru 6.

1. Secure tow vehicle to drawbar (31, Figure 4-4, Sheet 1).

w The safety cable located on the surge actuator of the engine trailer tow bar shall be connected each time the trailer is towed. Failure to comply could result in injury to personnel or damage to equip-ment.

2. Attach surge actuator safety cable to tow vehicle.

3. Release forward and aft hand brakes (1).

4. Remove the lift trailer from the transport trailer.

c

• Do not back trailer without disconnecting brake line. Failure to comply could cause damage to equipment.

• Do not back trailer with pressure applied to the surge actuator of the engine trailer. Failure to comply could cause damage to equipment.

NOTE

Omit steps 5 thru 6 if the trailer is not being backed up.

5. Ensure the surge actuator is in the neutral position (bellows is not compressed).

3-5. SHORING PROCEDURES FOR AIR/

GROUND SHIPMENT.

NOTE

Refer to TO 1C-17A-9 for airlift shoring proce-dures.

3-6. Shoring of the engine lift trailer for ground shipment is as follows (Refer to Figure 3-2):

1. Place two stacks of shoring 41 long by 12 wide by

15.5 to 17.5 inches high, longitudinally between the floor and lower frame parallel to each other. Use additional pieces of shoring as needed to maintain the maximum gap of one inch or less between the frame and shoring.

2. Shoring should be centered as close to the trailer center of gravity as possible and secured in place with tiedown straps.

CHANGE 1 3-3

3-7. ALTERNATE SHORING PROCEDURES.

3-8. Place protective shoring (32 by 32 by 3/4 inches) under stabilizing struts and lower the stabilizing pads onto the protective shoring.
