RIGGING STEPS
1. Position apex fitting in the trailer bed. Route outer sling legs 1 and 2 to the front of the trailer
and inner sling legs 3 and 4 to the rear. Sling legs 1 and 3 must be on the left side of the
load.
2. Loop the chain end of sling leg 1 through the left front lift provision located on the left
front corner of the trailer. Place the correct link from Table 3-4 in the grab hook. Repeat
with sling leg 2 through the right front lift provision. Secure excess chain with Type III
nylon cord.
3. Route the chain end of sling leg 3 through the left rear lift provision. Place the correct
link from Table 3-4 in the grab hook. Repeat with sling leg 4 through the right rear lift
provision.
4. Cluster and tie (breakaway technique) all sling legs together on top of the trailer to

2. The rigging procedures for the M149 Water Trailer (US Army) are located in
Chapter 16.
z
Materials. The following materials are required to rig this load:
„ Multileg sling set (15,000-pound capacity).
„ Tape, adhesive, pressure-sensitive, 2-inch wide roll.
„ Cord, nylon, Type III, 550-pound breaking strength.
„ Webbing, cotton, 1/4-inch, 80-pound breaking strength.
„ Felt sheet, cattle hair, Type IV, 1/2-inch or suitable substitute.
z
Personnel. Two persons can prepare and rig this load in 10 minutes.
z
Procedures. The following procedures apply to this load:
„ Preparation. Prepare the load using the following steps:
─ Secure all loose chains, hoses, and cables to the trailer drawbar with tape or Type III
nylon cord.
─ Ensure the tongue wheel is locked in the down position.
─ Close the tank lid and secure.
─ Ensure that one trailer brake is set.
„ Rigging. Rig the load according to the steps in Figure 3-5.
„ Hookup. The hookup team stands on the trailer fenders or the front of the trailer. The
static wand person discharges the static electricity with the static wand. The hookup person
places the apex fitting onto the aircraft cargo hook. The hookup team then carefully dismounts
the vehicle and remains close to the load as the helicopter removes slack from the sling legs.
When successful hookup is assured, the hookup team quickly exits the area underneath the
helicopter to the designated rendezvous point.
„ Derigging. Derigging is the reverse of the preparation and rigging procedures.

Certified Single-Point Rigging Procedures for Trailers
─ At each corner of the trailer, slide the lifting provisions out until they are completely
extended. Do not lift the trailer unless the provisions are fully extended and secured in
position.
─ Remove the side and end panels. Place two panels side by side on the trailer so that the
panel ends are approximately 10 inches from the front of the trailer. Make sure the
panels are positioned lengthwise on the trailer. Place the remaining panels on top of
the respective panels on the trailer.
─ Secure the panels on the trailer with the tie-down straps. Attach the hook end of one tie-
down strap to a tie-down ring on the trailer bed beside the panels approximately 1 foot
from the end of the panels. Connect and tighten the ratchet end to a tie-down ring on
the other side of the panels. Secure loose end of strap. Repeat with a second tie-down
strap at the other end of the panels.
─ To secure the panels lengthwise, route the hook end of one tie-down strap around the
vertical metal stiffeners on the top panel of the stack of panels on the left side of the
trailer. Attach the hook end to a tie-down ring on the front end of the trailer bed.
Connect and tighten the ratchet end to a tie-down ring on the other end of the stack of
panels. Secure loose end of strap. Repeat with a second tie-down strap on the other
stack of panels.
─ Tape or tie the intervehicular cable, hoses, and safety chains firmly to the top of the
drawbar with tape or Type III nylon cord.
─ Engage the parking brake.
„ Rigging. Rig the load according to the steps in Figure 3-6.
„ Hookup. The hookup team stands on the bed of the trailer. The static wand person
discharges the static electricity with the static wand. The hookup person places the apex fitting
onto the aircraft cargo hook. The hookup team then carefully dismounts the vehicle and remains
close to the load as the helicopter removes slack from the sling legs. When successful hookup is

Certified Single-Point Rigging Procedures for Trailers
„ Hookup. The hookup team stands on top of the trailer. The static wand person discharges
the static electricity with the static wand. The hookup person places the apex fitting onto the
aircraft cargo hook. The hookup team then carefully dismounts the vehicle and remains close to
the load as the helicopter removes slack from the sling legs. When successful hookup is
assured, the hookup team quickly exits the area underneath the helicopter to the designated
rendezvous point.
„ Derigging. Derigging is the reverse of the preparation and rigging procedures.
RIGGING STEPS
1. Position apex fitting on top of the trailer. Route outer sling legs 1 and 2 to the front of the
trailer (lunette end) and inner sling legs 3 and 4 to the rear. Sling legs 1 and 3 must be on
the left side of the load.
2. Loop the chain end of sling leg 1 through the left front lift provision located on the aluminum
frame attached to the trailer. Do not use the trailer lifting provisions attached to the chassis.
Place the correct link from Table 3-12 in the grab hook. Repeat with sling leg 2 through the
right front lift provision.
3. Route the chain end of sling leg 3 through the left rear lift provision located on the aluminum
frame attached to the trailer. Do not use the trailer lifting provisions attached to the chassis.
Place the correct link from Table 3-12 in the grab hook. Repeat with sling leg 4 through the
right rear lift provision.
4. Cluster and tie (breakaway technique) all sling legs together on top of the trailer to prevent
entanglement during hookup and lift-off.

„ Padding, Cellulose.
z
Personnel. Two persons can prepare and rig this load in 20 minutes.
z
Procedures. The following procedures apply to this load:
„ Preparation. Prepare the load using the following steps:
─ Connect one additional chain length to each chain of the sling set with the coupling link.
─ Engage the trailer parking brake.
─ Secure the doors closed with Type III nylon cord.
─ Place the radar set in the travel mode and secure the antenna cover to the antenna with
tape.
„ Rigging. Rig the load according to the steps in Figure 3-13.
„ Hookup. The hookup team stands on top of the ATG trailer frame. The static wand person
discharges the static electricity with the static wand. The hookup person places the apex fitting
onto the aircraft cargo hook. The hookup team then carefully dismounts the ATG and remains
close to the load as the helicopter removes slack from the sling legs. When successful hookup is
assured, the hookup team quickly exits the area underneath the helicopter to the designated
rendezvous point.
Notes. 1. Do not stand on the radar panel during hookup.
2. Due to limited clearance between the helicopter and the top of the ATG, the hookup
team may want to use an extended sling system on this load and hook this load from
the ground or the bed of a truck. Polyester round slings are recommended for use as
vertical pendants. The extended sling legs may not be ideal for flying this load "nap
of the earth" in a tactical environment.
Note. Hookup of this load presents substantial risk of damage to the load or injury to the
hookup personnel. Use of a reach pendant is recommended for this load.

Note. This load is flown with the lunette facing aft at an approximate 12 degree angle.
1. Position the apex fitting beside the trailer. Route outer sling legs 1 and 2 to the front (lunette
end) of the trailer and inner sling legs 3 and 4 to the rear. Sling legs 1 and 3 must be on the
left side of the load.
2. Loop the chain end of sling leg 1 through the left front lift provision. Place the correct link from
Table 3-26 in the grab hook. Repeat with sling leg 2 through the right front lift provision.
Secure excess chain with Type III nylon cord.
3. Route the chain end of sling leg 3 through the left rear lift provision. Place the correct link
from Table 3-26 in the grab hook. Repeat with sling leg 4 through the right rear lift provision.
Secure excess chain with Type III nylon cord.
4. Pad each chain with felt padding. Secure the padding with tape.
5. Install a 17-foot polyester round sling on the bolt end of the apex fitting on the sling set. Tape
the eye of the sling to prevent the apex fitting from rotating through the eye.
6. Place the free end of the 17-foot polyester round sling on the bell portion of the additional
apex fitting. Tape the eye of the sling to prevent the apex fitting from rotating through the
eye.
7. Cluster and tie (breakaway technique) all sling legs together on top of the trailer to prevent
entanglement during hookup and lift-off.
