vice. Bolted access plates are provided for entrance into points where other access is not provided.
(3) Ramp. The steel bow ramp is hinged at the bottom and mounted so that an inflatable synthetic rubber seal will make
the seams at the bottom and sides watertight. There is a mechanical ramp latch port and starboard. The ramp seal inflation-
deflation valve is located on the starboard side near the ramp latch. Recessed crossover foot pockets are installed below the top
of the ramp. The ramp is hydraulically operated by actuating cylinder through use of air controls. The piston rods of the actuating
cylinders are connected to movable blocks by forged steel clevises working in conjunction with fixed sheaves at the bow. Wire rope is
installed in this multiplying motion block arrangement.
(4) Rigging and securing devices. A cast steel open chock is on the centerline of the LARC stern on the main deck.
Three closed cast steel chocks are on both sides of the main deck. A cast steel closed chock is at the centerline of the ramp near the
top. There are four mooring cleats on the main deck, two on each side. Two swivel combination towing lugs and jacking pads are
located on the bow. Two swivel towing lugs and two jacking pads are located on the stern. Lifelines of wire rope with plastic covering
are attached to removable steel stanchions on each side and just aft of the cargo well. Fenders are of molded neoprene and are level
with the top deck. The cargo well bulkhead is protected by removable, vertically placed timbers (battens). Cargo lashing lugs of
round bars are welded in the cargo well. A recessed steel lug with a drilled hole for the shackle is located at the intersection of the
cargo deck and the aft cargo well bulkhead on the centerline of the LARC. This pad serves as a bitter end for the winch line. Hull
lifting pads are recessed in the cargo well bulkheads over each wheel support. Each pad is equipped with a removable shackle.

Storage tanks.
CAUTION
The spare lube oil tanks must be clearly labeled. Make certain that fuel oil is
not put in the lube oil tanks and lube oil is not put in the fuel oil tanks. Be sure
to avoid a similar mistake with the hydraulic oil tank.
Two 30-gailon spare lube oil storage tanks (fig. 3-5) are located amidship, one port and one starboard. Each tank is filled from the
main deck and has two 15-gailon compartments for different weight oils. Normally, these are SAE 10 and SAE 30 oils. Two 300-
gallon fuel oil tanks are located forward, one port and one starboard, and are also filled from the main deck. The hydraulic oil tank is
located amidship under the main cargo deck, and is filled from underneath a hatch cover on the starboard side. A 12-foot boat hook,
mounted on spring clips is located at deck level on the aft side of the cargo well aft bulwark. Mooring lines are stowed in the
starboard aft wing compartments.
(6) Windshield wiper. The air-driven windshield wiper is located on the center front window of the cab. A knob on the
instrument panel controls starting, stopping, and speed of the wiper (para 2-8).
