Palletized Load System Trailer (PLST) M1076 A1.

The PLST M1076 A1 (Figure 1, Item 7) is a three axle trailer designed to carry Flatracks (FR) and ISO containers

up to a gross weight of 35,750 (16,231 kg). Flatracks and Engineering Mission Modules (EMM) are loaded/unloaded

onto the PLST M1076 A1 (Figure 1, Item 7) using the Load Handling System (LHS). It can accommodate both full

and partial loaded flatracks. ISO containers are loaded/unloaded onto the PLST M1076 A1 (Figure 1, Item 7) using

the Load Handling System (LHS) with either a Container Handling Unit (CHU) or Enhanced Container Handling Unit

(ECHU). This is done with the use of the cart (Figure 1, Item 1) that is located on the back of the PLST M1076 A1

(Figure 1, Item 7). The cart (Figure 1, Item 1) can be positioned in three different configurations (container mode,

flatrack mode, or stored on the bumper) depending on the mission. Guides (Figure 1, Item 2) laterally position the

FR on the trailer rear stops (Figure 1, Item 8) and these locate the longitudinal position of the FR in relation to the

PLST M1076 A1 (Figure 1, Item 7). These stops prevent the FR from sliding rearward. A pneumatic locking device

(Figure 1, Item 6), located between the frame rails just above the second axle, hooks to engage the lock points and

secure the FR to the PLST M1076 A1 (Figure 1, Item 7). An air valve controls the position of the lock hooks. Springs

retain the hooks in the locked position. The PLST M1076 A1 (Figure 1, Item 7) has a standard 12 volt electrical

system with 24 volt military adapters. Also provided are two intervehicular electrical connecting cables (Figure 1,
