Section I.
GENERAL INFORMATION
This chapter provides general information, equipment description and principles of operation for both configurations of
the Container Roll-In/Out Platform (M3 CROP).
a. Type of Manual.
Operation and maintenance manual, including Repair Parts and Special Tools
List (RPSTL).
b. Model Number and Equipment Name.
The Container Roll-In/Out Platform (CROP) part
number is 12468780, Model M3, NSN 3990-01-442-2751. Figures 1-1 and 1-1a illustrate the M3 CROPs in various
configurations. M3 CROP serialization (S/N SC09001 and up) identifies the latest model of the M3 CROP.
c. Purpose of Equipment.
The M3 CROP is a flat cargo body with a folding front end structure
assembly, designed for use with the Palletized Load System (PLS) truck and trailer. The M3 CROP is designed to be
loaded on the PLS truck and trailer and in an ISO container using the Load Handling System (LHS). The M3 CROP is
capable of being transported by other modes of transportation through the supply distribution system in a stand-alone con-
figuration, or in an ISO container.
d. Equipment Specifics.
The M3 CROP (S/N SC09001 and up) differs from the original configura-
tion in how the handling equipment is conveniently stored on the front of the platform for quick accessibility, the design of
the end structure assembly (A-frame) and a rear underneath storage area for the hook arm extension. Functionally, all oper-
ations, handling, PMCS, maintenance and repair procedures are basically identical for both versions of the M3 CROP.
Specific tasks that apply only to S/N SC09001 and up are cited in Change 1 to this manual.
