Section I. GENERAL INFORMATION
This chapter provides general information, equipment description and principles of operation for the Container
Roll-In/Out Platform (M3A1 CROP).
a.
Type of Manual. Operation and maintenance manual, including Repair Parts and Special Tool
List (RPSTL).
b.
Model Number and Equipment Name. The Container Roll-In/Out Platform (CROP) part
number is 3-33000, Model M3Al, NSN 3990-01-450-5671. The M3A1 CROP is manufactured by Hyundai Preci-
sion America, San Diego, CA. Figure 6-1 illustrates the M3A1 CROP in various configurations.
c.
Purpose of Equipment. The M3A1 CROP is a flat cargo body with a folding front A-frame
assembly, designed for use with the Palletized Load System (PLS) truck and trailer. The M3Al CROP is designed
to be loaded/unloaded on the PLS truck and trailer and in an ISO container using the PLS Load Handling System
(LHS). The M3A1 CROP is capable of being transported by other modes of transportation through the supply dis-
tribution system in a stand-alone configuration, or in an ISO container.
The M3A1 CROP has a total service life of 20 years which allows for extended periods of operation in a corrosive
environment. A corrosive environment includes exposure to high humidity, salt spray, road-deicing chemicals,
gravel, and atmospheric contamination. However, because M3A1 CROP is completely galvanized, no action
beyond normal washing and repair of damaged areas is necessary to control corrosion. To prevent moisture accu-
mulation, drain holes are provided on structural areas where necessary. Stowage boxes are provided with drains.
Lubricate the M3A1 CROP according to Appendix K. Clean with high pressure water.
