Figure 9-12. Engine Trailer
(3)
Principles of operation. The rails on the
trailer can be mounted two ways, either 30 or 48 inches
apart. There are rail stop assemblies at both end of
each rail to prevent the load from sliding off. The rail
stops are spring-loaded to the up position. The towbar
allows the engine trailer to be moved by a tow vehicle.
The pintle hook on the rear of the trailer permits the
trailers, to be joined together for towing by a single tow
vehicle. Two brake assemblies which are set by
depressing the pedal assemblies are located at the right
and left rear axles. The brakes prevent the trailer from
rolling when parked or while being loaded or unloaded.
The front wheels are steerable by using the towbar.
(4)
Safety practices and procedures. The
following special precautions should be observed while
using the engine trailer:
· Do not put fingers on the rails when sliding loads
on or off.
· Set the brakes so the trailer does not roll.
· Do not tow the trailer faster than 20 mph.
Remember that the momentum of a loaded,
moving trailer will try to keep the trailer moving.
(d)
When towing two or more engine
trailers together, allow for a decreasing turn radius.
(5)
Operating procedures. The following
procedures pertain to the operation of the engine trailer:
(a)
Move the trailer into position for
loading. The trailer may be moved and steered by hand
if fine adjustments to positioning are required. Set the
brakes.
(b)
Install the load.
(c)
Position the load to keep the center
of gravity at the midway point between the axles.
