Section I. GENERAL

TM 55-2420-224-14

2-1. Scope

This chapter provides transportability characteris-

tics of the SEE, HME, and HMMH.

2-2. Description

The SEE, HME, and HMMH are commercial items
of construction equipment. The tractor portion of
the equipment is a light truck chassis equipped
with a diesel engine, multispeed range transmis­sion, and offroad flotation tires. The tractor has a
45-mile-per-hour (72-km/h) highway convoy speed
as well as a full drive rough-terrain capability.

a. The SEE tractor configuration consists of the
basic tractor with a 3/4-cubic-yard-capacity front
end loader and rear-mounted backhoe. The back­hoe has a 7-cubic-foot-capacity bucket, as shown in
figure 2-1.

b. The HME variant consists of the same basic
tractor as the SEE, but with a dozer blade (85
inches wide and 32 inches high) on the front end

and an entrencher on the rear. No photograph is
available at this time.

c. The HMMH variant consists of the same

basic tractor as the SEE, but with a 4,000-pound

(1814-kg)-capacity forklift mounted to the front

and a 6,000 pound (2722-kg)-capacity crane at-

tached to the rear of the vehicle, as shown in

figure 2-2.

2-3. Transportability Drawings

Figures 2-3 through 2-5 are detailed side- and
rear-view transportability drawings of the SEE,
HME, and HMMH with dimensions, tiedown and
lifting provisions, and load-rating capacities.

4-6. Transport by US Aircraft

a. The SEE, when shipped in C–130 and C–141
aircraft, will have the backhoe attachment in the
operational configuration. The SEE should be
backed into the C-130 and C-141 aircraft using
two qualified operators. One driver operates the
tractor and the other operates the backhoe, adjust-

ing height during loading and unloading opera-

tions. Each SEE requires two stacks of parking

shoring (2 x 6 inches x 4 feet, two per stack)

between the front end loader and the aircraft floor.

Also, place two stacks of shoring (2 x 6 inches x 4

feet, two per stack) under lowered bucket and

aircraft floor.

b. The HME and HMMH, when shipped in
C–130 and C–141 aircraft, must be in the travel
configuration.

(1) HME. Install 1/2-inch wire rope (safety

cable) through ROPS and over entrenched attach-

ment, forming a loop. Secure the loop by pulling
and installing the wire rope taut (not tight) with

two 1/2-inch clips. Each HME requires two stacks

4-1

TM 55-2420-224-14

of parking shoring (2 x 6 inches x 4 feet, two per
stack) between the front dozer blade and the
aircraft floor.

(2) HMMH. Install 1/2-inch wire rope (safety
cable) around top crane arm and through left
center tiedown provision on chassis, forming a
loop. Secure the loop by pulling the wire rope taut
(not tight) and installing two 1/2-inch clips. Repeat
same procedure for right side, except loop wire
rope through right provision on chassis. Each
HMMH requires two stacks of parking shoring (2

x 6 inches x 5 feet, two per stack) between the
front forklift tines and the aircraft floor. Also the
rear outriggers are to be secured with 1/2-inch
wire rope (safety cable) looped around each outrig­ger and secured with two 1/2-inch clips.

c. The C–5 aircraft can transport the SEE,

HME, and HMMH in the travel configurations.

(1) SEE. Install 1/2-inch wire rope (safety
cable) taut (not tight) around the ROPS and the
backhoe attachment and secure with two 1/2-inch
clips. Also, install on right outrigger a 1/2-inch
wire rope (safety cable) taut (not tight) through the
bucket tiedown provisional and around outriggers.
Repeat procedures for left outrigger. Each SEE
requires two stacks of parking shoring (2 x 6
inches x 4 feet, two per stack) between the front
end loader and the aircraft floor.

(2) HME and HMMH. To transport the HME
and HMMH in the C–5 aircraft, follow the same
procedures in paragraph 4-6b.

d. The shoring is required to protect the aircraft
floor and any downward motion of the front or
rear implements on the aircraft floor.

e. All shoring material will be furnished by the
shipper and installed as directed by the aircraft

loadmaster.

f. The aircraft commander or his/her representa-

tive ensures that the vehicles are loaded/unloaded
and properly secured in the aircraft according to
the criteria in section IV of the appropriate techni­cal order.

g. Typical tiedown diagrams (figs 4-1 through

4–3) are based on acceptable methods. They can be
used as a guide for loading and securing the SEE,

HME, and HMMH aboard aircraft and also for

preparing a vehicle for air transport. The tiedowns
are part of the aircraft equipment.

4-7. Transport by LVAD and LAPE

The SEE is certified for low altitude parachute

extraction (LAPE) from US Air Force C–130 air­craft and certified for low velocity airdrop (LVAD)

from US Air Force C-130 and C-141 aircraft.

Preparation and procedures for LAPE and LVAD

airdrops are described in FM 10–539 and TO
13C7-1-17.

4-8. Helicopter Transport

The SEE is within the external lift capability of
the CH–47D helicopter in either single-hook (fig
4–3) or dual-hook (fig 4–4) configuration at air­speeds of 100 knots. The load is also suitable for
external transport by the CH–54 helicopter (fig
4-5) at airspeeds of 95 knots.

a. Materials.

(1) Sling set (25,000-pound capacity) – one

each.

(2) Nylon cord, Type III-as required.
(3) Cotton webbing–as required.
(4) Tape, adhesive, pressure-sensitive, 2-inch

(1) Ensure that the front end loader assembly
travel locks at the ends of both front end loader
boom cylinders are properly pinned in place.

(2) Secure steering wheel, doors, and all loose
equipment with cord and tape as necessary.

(3) Fold side mirrors inboard and tie or tape
as required.

(4) Tape windshield wipers to windshield.

(5) Securely tie and tape engine compartment
hood.

(6) Tie or tape the hydraulic lines and hoses
close to the forward lifting provisions to prevent
possible entanglement during hookup.

c. Rigging Procedures.

(1) Place apex fitting on top of the falling
object protection system (FOPS). Route the outer
sling legs (1 and 2) to the front of the SEE and the
inner sling legs (3 and 4) to the rear of the SEE.

NOTE

Sling legs 1 and 3 should be the same side

of the load.

(2) Loop the chain ends of sling legs 1 and 2
through the respective front lifting provisions, and

insert link 3 into the grabhook. Wrap a felt sheet
around the chain ends of the sling legs and secure
with tape or nylon cord (fig 4–7).
