CHAPTER 2

TRANSPORTABILITY DATA

Section I. GENERAL 2-1. Scope This chapter provides a general description and identification photographs of the D7 tractors as well as transportability data necessary in moving the tractors.

2-2. Description The D7 tractor is a commercial, track-type tractor modified for the US Army. It is diesel-engine-driven, has a rollover protection system (ROPS) canopy, and has a straight blade. It also has either a rear-mounted towing winch or a ripper. However, the rip-per and winch are not interchangeable. The ripper can be mounted only on D7 tractors equipped with ripper mounting devices; the winch can be mounted only on D7 tractors equipped for a winch. Figures 2–

1 and 2-2 show the D7G with ripper and the D7G with winch, respectively. The D7E and D7F model tractors are similar in appearance to the D7G.

2-3. Transportability Drawings Figures 2–3 through 2–6 are detailed side- and end-elevation transportability drawings of the D7G with ripper and the D7G with winch. These drawings show dimensions and lifting and tiedown provision locations with load rating capacities. The D7E and F models have similar features except the weights and dimensions vary as shown in table 2–1. Also, the D7E and F models have one extra tiedown provision on the track roller frame. The provision is located between the other two multipurpose provisions on each side.

Section II. CHARACTERISTICS AND RELATED DATA

2-4. General Transportability Characteristics The data in this manual apply to the model number or national stock number (NSN) shown. Changes in model number or NSN may affect the loadability of the item as related to the guidance in this manual.

Dimensions and weights are given for both opera-tional and reduced configurations. The reduced D7 configuration consists of removing the ROPS, exhaust stack, precleaned, blade, and winch or rip-per. Figures 2–7 through 2–11 show the removable items.

2-5. Unusual Characteristics require special attention be given to temperature, atmospheric pressure, or humidity variations during exposure to normal transportation environments.

2-6. Hazardous and Dangerous Characteristics The D7 crawler tractors will not present any special hazardous characteristics during exposure to normal transportation environments.

NOTE

CHAPTER 4

AIR TRANSPORTABILITY GUIDANCE

4-1. Scope This chapter provides air transportability guidance for moving the Cater-pillar D7 crawler tractors. It covers significant safety considerations and pre-scribes the materials required to prepare, load, and tie down the tractor on, or unload the tractor from, US Air Force aircraft.

4-2. Maximum Utilization of Aircraft The loads described in this section are not maximum aircraft loads. General guidance on total cargoloads and operating ranges is in TM 38–236/AFP 71–8.

Additional cargo and/or personnel within allowable load limits and restrictions prescribed by pertinent safety regulations can be transported.

4-3. Applicability The D7 tractors are transportable in C-130, C-141, and C–5 aircraft. Procedures in this manual and those prescribed in TO 1C–130A–9, TO 1C-141A–9, and TO 1C–5A–9 apply.

4-4. Safety In addition to the safety precautions in chapter 3, note the following instructions:

a. The activity offering the equipment for air transport must notify the aircraft commander, or designated representative, when hazardous materials are to be transported. It must also state whether these materials have been prepared for shipment according to TM 38-250/AFR 71-4.

b. Ensure the tractor fuel tank is no more than one-half full.

c. Tie down the tractor according to procedures in

TO 1C-XXX-9.

d. Check each tractor carefully to ensure that all loose items are properly stowed and secured.

e. Transport the tractor aboard C–130 and C–141 aircraft in the reduced configuration (remove blade, ripper or winch, ROPS, and exhaust stack).

f. Use rolling and parking shoring aboard all air-craft.

g. Park the tractor between fuselage stations 337 and 682 on C–130 aircraft.

h. Straight-in load the tractor aboard C–141 air-craft.

i. Adequately restrain the tractor and all accom-panying loads. The tractor restraint system must withstand loadings of 3g forward, 2g vertically up, 4.5g vertically clown, and 1.5g aft and lateral.

WARNING

Fire extinguishers must be readily available during all loading and unloading operations.

WARNING

Proper ventilation must be provided during loading and unloading operations. Prolonged exposure to carbon monoxide fumes could be fatal.

WARNING

On C–130 aircraft, the width of the tractor may not allow for a proper safety aisle for passengers, in which case passengers would be limited to mission essential personnel only.

CAUTION

The tractor must not exceed 3 mph inside the aircraft or on the loading ramp.

CAUTION

The clearance between the dual rails on the C–130 is critical and will require careful maneuvering or building the shoring above the rails.

4-5. Preparation of the Vehicle

a. Inspect the D7 tractor for leaks, damage, and operation; repair as required.

b. Fabricate and place shoring.

c. Reduce crawler (required for C-130 and C–141 transport) by removing blade, ripper or winch, ROPS, and exhaust stack.

d. Palletize removed items.

NOTE

The tractor must be loaded onto a semi-trailer or similar transporter for straight-in loading aboard C–141 aircraft.

NOTE

The tractor ripper shanks should be turned upward when transporting the operational tractor aboard C–5 aircraft.

4-6. Transport by US Air Force Aircraft This tractor is tied down according to the applicable TO 1C–XXX–9, section IV. Figure 4–1 shows the suggested tiedown pattern for the D7G in the C–130 aircraft. The suggested tiedown pattern for the D7E and F tractors is similar to the D7G except that the transporter should use the additional center tiedown provisions located on the track roller frames in between the other two multipurpose provisions. This additional tiedown is required to adequately restrain the D7E and F tractors for air transport because the D7E and F tractors are heavier than the D7G. For C–141 and C–5 transport, fewer tiedown devices are

Section III. TRANSPORT BY TRACTOR/SEMITRAILER

5-4. General.

This section covers the D7 tractors transported by the M916/M870 and M123A1C/M172A1 truck-tractor/ semitrailer combinations. The D7 tractors must be in the reduced configuration for highway transport on these combinations. The exhaust stack and pre-cleaner can be stored and secured on the tractor. The blade, pusher arms,ROPS, and winch or carrier beam and ripper must be transported on a separate truck-tractor semitrailer combination and can be positioned as shown in figure 5-1 for the D7G. Move-ment over paved public highways will not be made without specific approval as outlined in AR 55-162.

5-5. Transport of the D7 Tractors on the M916/M870 and M123A1C/ M172A1 Truck-Tractor/Semitrailer Combinations

a. Restrictions. Restrictions for D7 tractor trans-port on the M916/M870 and M123A1C/M172A1 com-binations are major. Both legal and permit limits are exceeded for CONUS transport. Width, single-axle load, and most combination gross vehicle weights exceed legal limits, but are within permit limits for both combinations, Some additional restrictions will be encountered when transporting the D7 by the M916/M870 because of the length of this combination.

However, these restrictions are also within permit limits. Some permit limits, however will be exceeded for the high tandem-axle loadings and combination gross vehicle weights. Of the two transporters, the M123A1C/M172A1 combination will encounter the most restrictions when hauling the D7. In general, overseas highway transport is more restrictive than CONUS highway transport. Legal limits for overseas are identified in “Limits of Motor Vehicle Sizes and Weights,” International Road Federation, Geneva, Switzerland.

b. Materials for Blocking and Tiedown. Adequate tiedown chains and binders for securing the D7 crawler tractors are basic issue items (BII). Table 5- 1 gives the bill of materials for blocking and tiedown of the D7 tractor on the M870 semitrailer. Table 5-2 provides data concerning application of materials for tiedown on the M870. Blocking and tiedown diagrams compatible with standard loading practices are provided in figures 5–2 and 5–3. These procedures will offer adequate restraint against forces encoun-tered during movement at normal speeds and operat-ing conditions.

NOTE

The tiedown procedure for the D7E, F, and G is similar except that the shipper must use the middle tiedown provision on the D7E and F, as shown in figure 5–2, as an addi-tional tiedown point. The center tiedown provision is not available on the D7G;

however, additional tiedown is not required on this model. The D7E and F models require the additional tiedown because they are heavier than the D7G.

c. Loading.

WARNING

At no time during loading operations should personnel, other than the guide and the driver of the tractor, be on the semitrailer bed.

WARNING

Loading should not be conducted with the semitrailer sideways on a slope that exceeds 10 percent or with a tractor-to-semi-trailer offset angle greater than 5°. Loading also should not be conducted on a severe down-grade, because the tractor driver may not be able to safely control movement of the tractor.

e. Inspect all lifting provisions, including lifting eyes and shackles, to ensure they are not damaged.

f. Caution personnel not to walk under items being lifted.

g. Ensure all lifts have at least two tag lines attached to control the swing of the lift while sus-pended.

NOTE

When the D7 tractor is loaded on vessels that are adequately ventilated by power blowers, such as the roll-on/roll-off (RORO) ships, fuel tanks need not be drained.

6-3. Water Shipment The D7 tractor is transportable by a great variety of inland-waterway cargo carriers, lighters, and barges and by all seagoing cargo vessels.

NOTE

The methods described in this chapter for lifting and securing the D7 tractor are sug-gested procedures. Other methods of hand-ling and stowage may be used to accomplish safe delivery without damage.

Section II. LOADING AND SECURING

6-4. General Rules for Stowing

a. General. When possible, stow the D7 tractor below deck for protection. In general, good stowage means placing vehicles fore and aft as close together as practical, with minimum spacing (about 4 to 6 inches) between outer vehicles and the sweat-boards. Also, protect breakable parts and stow spare parts in or near the parent item. Set the brakes and place the transmission control in neutral.

NOTE

The ripper shanks should be turned upward for marine transport.

Secure the D7 tractors with blocks in front, in rear, and on both sides of the tracks to adequately restrain the vehicles. Brace individual tractor blocks to bulkheads, stanchions, and other vehicle blocks. Lash all vehicles with wire rope or chains to nearby padeyes, bulkheads, or stanchions.

b. Lifting. The correct lifting points on the D7 trac-tor are on the front and rear of the track roller frames. Figure 6-1 shows a typical lifting diagram.

c. Loading. Load the D7 tractor on vessels in the operational configuration when possible to avoid time-consuming and costly disassembly. Make sure the hatch girder clearance of the specified vessel is greater than 134 inches (3.40 m) for the operational tractor. With the ROPS and exhaust stack removal, the D7F and G tractors require a hatch girder clear-ance greater than 96 inches (2.44 m). The D7E trac-tor requires a hatch girder clearance of 101 inches (2.57 m). The D7 can be driven, or lifted by cranes of adequate capacity, aboard landing craft beach dis-charge lighters, heavy amphibious lighters, and land-ing ships. It also can be driven or towed aboard RORO vessels, or onto the decks of barges from a pier, when tidal conditions are suitable and ramps are available. The D7 can be loaded onto seagoing vessels by shoreside of floating cranes of adequate capacity or by heavy-lift ship’s gear. The D7 tractor cannot be transported on the LARC-V or LARC-XV lighterage vessels. Transport by the LACV-30 can be made pos-sible by reducing the D7 tractor weight to no more than 45,000 pounds. This involves removing at least two of the D7 major components such as the blade, ROPS, ripper, or winch. Figure 6–2 shows typical blocking and tiedown details. Bill of and application of materials for blocking and tiedown are given in tables 6-1 and 6-2.

CHAPTER 7

RAIL TRANSPORTABILITY GUIDANCE

Section I. GENERAL

7-1. Scope This chapter provides rail transportability guidance for moving of the Caterpillar D7 crawler tractor. It covers physical characteristics and safety considera-tions. It also prescribes the materials and guidance required to prepare, load, and tie down the D7 tran-

7-3. General The transportability guidance in this section applies to transport of the tractor on CONUS railways. It includes both single and multiple movements for the types of flatcars normally used in moving this tractor.

7-4. Preparation Load the D7 tractor on the flatcar in the operational configuration, when possible, to avoid time-consum-ing and costly disassembly. However, the D7 may require disassembly along some rail lines where restrictions such as tunnels or bridges occur. When transporting the D7 tractor with minimum restric-tions in CONUS on a standard 50-inch-high flatcar, remove the tractor dozer blade to reduce the width.

Remove the exhaust stack to reduce the height. The exhaust stack can be transported on the tractor if it is securely stowed. Also, turn the ripper shanks upward to prevent railcar damage.

7-5. Loading the D7 Crawler Tractor on General-Purpose Flatcars

a. The tractor may be placed in the tiedown posi-tion on the flatcar by a crane, or it may be driven or towed if a suitable ramp or bridge is available. When loading the vehicle by crane, follow the procedures and precautions in paragraphs 6-2 and 6-4b.

b. Figure 7–1 shows typical loading diagrams of the tractor on a general-purpose flatcar with a minimum width of 10 feet 4 inches. The type of blocking and tiedown shown is compatible with standard loading practices and provides adequate restraint against the forces encountered during movements at normal speeds. Figure 7–2 shows the D7 blocking and tiedown details.

CAUTION

Do not allow the tractor to exceed 3 miles tor on open-top flatcars.

7-2. Maximum Utilization of Railcars Additional cargo, as approved by the activity offering the items for transport, may be transported with the tractors.

Section II. TRANSPORT ON CONUS RAILWAYS per hour during loading and unloading oper-ations.

NOTE

A staggered nailing pattern should be used when lumber or laminated lumber is nailed to the floor of a railcar. The nailing pattern for an upper piece of lumber should be adjusted so that a nail will not be driven into or against a nail in a lower piece of lumber.

NOTE

For the D7E and F models, the middle tiedown provision, located on each side of the track roller frame between the multipur-pose (lifting and tiedown) provisions, can be used if additional tiedown is desired.

c. Table 7–1 is the bill of materials for blocking and tiedown of the D7 tractor on a CONUS general-pur-pose flatcar. Table 7–2 provides information for the application of materials required to restrain the vehicle.

NOTE

Refer to figures 5–2 and 5–4 for other tiedown points that can be used for trans-porting the reduced D7 tractor.

7-6. Loading the D7 Crawler Tractor on Wooden-Deck Chain-Tiedown Flatcars

a. The tractor can be loaded on the wooden-deck chain-tiedown flatcars by the procedures in 7–5a.

b. Figure 7–3 shows a typical loading diagram of the D7 tractor on a wooden-deck chain-tiedown flat-car with a minimum width of 10 feet 4 inches.

GENERAL

1. Brakes must be tightly set and secured.

2. Tractors without ripper must have the rear left and right tiedowns attached to the rear towing pin. Maintain similar angles on tiedowns as shown on drawing.

3. General Loading Rules 1, 2, 4, 5, 7, 9, 14, 15, 19, 19A, and 19B appearing in section 1 of the Rules Governing the Loading of Com-modities on Open-Top Cars, published by the Association of Amer-ican Railroads, provide guidel ines that are mandatory in application.

c. Wooden-deck chain-tiedown flatcars, usually are equipped with four parallel channels that run the full length of the flatcar deck. Two channels are about 30 inches apart, and two other channels run along the outer edges of the car, or just inboard of the tread-way loading area of the car. These channels are recessed so that the top is flush with the deck surface. Each channel contains numerous (usually 8 to 12) chain anchors, each with an attached 10- to 12-foot chain. The chain anchors can be moved along- the channel and locked in place where needed. At the free end of the chain, pass a hook through the tiedown shackle on the vehicle being loaded and pull the chain hand-tight. Then hook it back onto itself or directly to the shackle. Apply tension to the chain by tightening a turnbuckle built into the chain assembly or by turning a ratchet or screwjack in the anchor block. Use an open-end wrench to tighten the turn-buckles. Use a ¾-inch square-drive, heavy-duty socket wrench to tighten the ratchet at the anchor blocks. Wire-tie open hooks to prevent them from becoming disconnected during over-the-road forces encountered en route. Table 7–3 gives the application of materials for tiedown of the D7 tractor on wooden-deck chain-tiedown flatcars.

GENERAL INSTRUCTIONS

1. Tractors without ripper must have the rear left and right tiedowns attached to the rear towing pin and tiedown provision on winch. Maintain similar angles on tiedowns as shown on drawing.

2. Loading rules 4, 5, 7, 11, 15(g), 19, 19A, 19B, and 19C in sec-tion 1 of the Rules Governing the Loading of Commodities on Open-Top Cars and Trailers, published by the Association of American Railroads, provides guidelines that are mandatory in application.

Section III. TRANSPORT ON FOREIGN RAILWAYS

7-7. General

The transportability guidance in this section applies to transport of the D7 tractor on foreign railways. It includes both single and multiple vehicle movements for the types of flatcars normally used for moving this type of equipment. When loaded on a suitable flatcar, the D7 tractor, in reduced configuration (para 7–4), can be transported for generally unrestricted rail movement throughout Europe. Some rail line clearances will require removal of the tractor ROPS, dozer blade, and exhaust stack to meet height requirements. Flatcars with a capacity of more than 20 metric tons must be used for transporting the D7 tractor with ripper. The ripper must be removed to reduce the tractor weight if flatcars with a suitable weight-carrying capacity are not available.

7 -6

7-8. Transport on Foreign-Service Flatcars

a. General. The D7 tractor is transportable on for-eign-service flatcars of adequate size and capacity.

Within Europe are many railcars that have a suitable size and capacity for transporting the D7. A list of them can be found in the European Railway Equip-ment Register.

b. Materials. The materials required for blocking and tiedown of the tractor on foreign-service flatcars are essentially the same as those used for transport-ing the vehicle within CONUS. The 4th Transporta-tion Command Pamphlet 55–2, Tiedown Guide for Rail Movements, provides detailed guidance. Fur-ther assistance can be obtained from the 1st Trans-portation Movement Control Agency, Oberussel Germany.
