2.1 MAINTENANCE CONCEPT:
This conveyor will not require special or new maintenance considerations. Maintenance operations can be
accomplished within the current maintenance concept for Material Handling Equipment.
Nature and extent of maintenance
Maintenance Allocation Chart (MAC): Maintenance will be performed as necessary by the category indicated in the
MAC (Appendix B) to retain and/or restore serviceability. Units may exceed their authorized scope and functions in the
MAC when approved by the appropriate commander.
Unit Maintenance: Is performed by the operator, crew and/or unit maintenance personnel. It is
characterized by quick turn-around based on repair by replacement and minor repairs. Inspections by sight and touch of
external and other easily accessible components. Lubrication, cleaning, preserving (to include painting), tightening, and
minor adjustments to easily accessible mechanical, electrical, and hydraulic systems.
Direct Support (DS) is characterized by one stop painting of skirts, fenders, body and hull sections.
Receive, store and issue Class IX supplies. Evacuation of unserviceable end items and modules to designated repair
General Support (GS) is characterized by: commodity oriented platoons performing repair of components
and end items in support of the theater supply system; back-up maintenance support to DS, Job Shop/bay or production
line operations: diagnosis and isolation of material, and module malfunctions to the internal part level; adjustment,
alignment and repair of materiel and modules as necessary , when authorized; repair of module by replacement of external
and internal parts; replacement of defective modules beyond the authorized capability of lower maintenance levels;
performance of heavy body, hull, turret, and frame repair; collection and classification of unserviceable or abandon Class
VII materiel for proper disposition; evacuation of unserviceable, unrepairable materiel through selected disposal channels;
fabrication or manufacture of repair parts, assemblies, components, jigs, and fixtures as approved by MACOMS (reference
AR 750-1 Chapter 2, Section I, Para 2-1, K).
(d)Depot: There is no scheduled depot maintenance on the conveyor belt.
Maintenance Expenditure Limit (MEL): The MEL is based on a life expectancy of 15 years. Repair limits are
based on 5Opercent of replacement cost for the first 10 years and 25 percent for the remaining 5 years (Appendix D).
