This Technical Manual TM 5-3810-294-34P covers the Harnischfeger Model M320T2 Truck-Mounted Crane, identified under FSN 3810-151-4431, and is dated June 1972. For collectors of U.S. Army technical manuals, military construction-equipment references, and Cold War field-support publications, this is a strong period document tied to a specialized and increasingly hard-to-find piece of Army engineer equipment.
Because this is a -34P technical manual, it belongs to the repair parts and special tools side of Army documentation at the higher maintenance level. Manuals in this category were intended to support the identification of assemblies, components, repair parts, and special tools required to keep equipment serviceable. That gives this publication strong technical and workshop-oriented value for collectors, researchers, and restorers.
The Harnischfeger Model M320T2 Truck-Mounted Crane
The Harnischfeger Model M320T2 Truck-Mounted Crane belongs to the broader family of military engineer, construction, lifting, and material-handling equipment. As identified by its nomenclature, it is a truck-mounted crane, placing it squarely in the support side of Army operations rather than in the category of conventional weapons or combat vehicles.
Equipment in this class was associated with lifting, loading, positioning, recovery support, and general construction work where a mobile heavy-lift platform was needed for field engineering tasks. The truck-mounted configuration gave machines like this the mobility needed for military service, while the crane arrangement made them useful for a wide range of engineer and support roles. In Army use, equipment like this fit naturally into the world of construction units, maintenance areas, engineer operations, and field-support activities where lifting capability was essential.
For collectors, that makes this manual especially interesting because it documents the technical side of Cold War military heavy equipment rather than more commonly seen combat hardware. It also has strong crossover appeal for anyone interested in military construction machinery, truck-mounted cranes, and U.S. Army engineer support systems. The inclusion of FSN 3810-151-4431 adds cataloging value for collectors who prefer manuals with a specific government stock-number reference rather than only general nomenclature.
What This Manual Covers
As a repair parts and special tools technical manual, TM 5-3810-294-34P would have been intended to support the higher-level maintenance and parts-support functions for the Harnischfeger Model M320T2 Truck-Mounted Crane.
In practical terms, a manual like this is especially relevant for:
- nomenclature and identification
- repair-parts identification
- assembly and component breakdowns
- special tools listings
- maintenance-related parts support
- archival and restoration research use
That makes it valuable not only as a collectible, but also as a practical reference for anyone studying how the Army supported mobile crane equipment during the Cold War period.
Historical Significance
The date June 1972 places this publication in the Cold War period, when the U.S. military maintained extensive technical literature covering not only weapons and vehicles, but also the engineer and construction equipment required to build, lift, recover, move, and support military operations. Manuals like this reflect a period when Army documentation extended into every part of the logistical chain, including cranes, lifting equipment, maintenance tools, and field-support systems.
For collectors and historians, this manual is especially relevant to subjects such as:
- Cold War U.S. Army technical manuals
- military construction and engineer equipment
- truck-mounted cranes and lifting machinery
- Army repair parts and special tools documentation
- dated military technical publications
Because it covers a specialized truck-mounted crane rather than a more common tactical vehicle or weapon system, it also adds variety to collections that already include standard ordnance or maintenance manuals.
About This Manual
This listing is for Technical Manual TM 5-3810-294-34P for the Harnischfeger Model M320T2 Truck-Mounted Crane, identified under FSN 3810-151-4431 and dated June 1972.
It is especially well suited for:
- U.S. Army technical manual collections
- Cold War engineer and heavy-equipment displays
- crane and lifting-equipment collections
- museum exhibits on military construction and support systems
- archive and research libraries focused on U.S. military technical publications
Because manuals were working documents, surviving examples are valued not only for their content, but also for their connection to real military maintenance and support practice.
Why This Manual Matters
Many military manuals focus on operator use or more visible front-line equipment. This one is useful because it documents the repair-parts and special-tools structure behind a mobile crane used for engineer and construction work in the field. That makes it especially relevant for collectors who want to preserve the broader technical and logistical picture of Army operations rather than only combat hardware.
For collectors, it is a solid stand-alone Cold War technical manual with a specialized subject focus. For researchers, it offers a useful reference point for Army crane documentation, parts-support systems, and construction-equipment maintenance history. For museums, it helps explain the behind-the-scenes machinery that supported lifting, recovery, and field engineering operations.
Ideal For
This manual is a strong fit for:
- U.S. Army technical manual collections
- Cold War engineer and support-equipment displays
- crane and lifting-equipment collections
- museum and archival reference libraries
- collectors of military paperwork and dated technical publications
