ROLL-ON/ROLL-OFF (RO/RO) PROCEDURES
NOTE
Refer to FM 55-17, Cargo Specialists' Handbook for further information on RO/RO procedures.
Introduction.
1.
a.
The yard tractor is used to load and unload trailers on ships during RO/RO operations.
b.
At all times, the yard tractor's movements are under the overall control of the RO/RO vehicle director. Loading and
unloading is accomplished by following the vehicle director's traffic control plan.
c.
Trailers are loaded by moving them from dockside to the appropriate level and hold on board ship. Once stowed,
crews secure trailers for shipping by lashing, shoring, blocking or bracing, as appropriate. Unloading is accomplished
by moving trailers from on board ship to dockside.
d.
In order to accomplish RO/RO, the yard tractor must operate up and down ramps on the ship. The grade of the ramps
will vary, depending on the tide and the weight of the ship at the time of loading or unloading. Under the worst case
scenario, the ramp could have a 12-15 degree grade.
e.
Ground guide assistance is mandatory when the yard tractor is operating on ramps. One ground guide must be sta-
tioned at the bottom of the ramp and another at the top. The operator and ground guides communicate with each other
using hand signals.
f.
The key to safe and timely RO/RO operations is teamwork between the yard tractor operator and the ground guides.
The driver cannot see most of the interference problems that arise between the trailer being towed and the ramp. The
ground guides can see these situations. They tell the operator when to raise or lower the fifth wheel in order to elimi-
nate the interference.
2.
RO/RO Regulations.
WARNING
Safe RO/RO operation depends on strict adherence to RO/RO regulations. Failure to do so may result in
injury or death to personnel or damage to equipment.
a.
Only qualified and screened operators are permitted to drive the yard tractor in RO/RO operations.
WARNING
Operation within the confines of a ship during RO/RO operation requires hearing protection. Failure to wear
hearing protection may result in hearing loss.
b.
All personnel working in vehicle operating areas MUST wear hearing protection.
c.
DO NOT move tractor about the ship without a ground guide present.
