About this file

This document is a parts catalog and technical manual for the DT50-55 crane, providing detailed component breakdowns, illustrations, and part lists for various major assemblies and systems. The manual is organized into chapters covering different crane subsystems, including the boom/turret/pedestal, swing drive, hydraulic systems, electrical components, and power units.

Key sections include detailed part lists with Allied Systems Company (ASC) part numbers, quantities, and descriptions for components such as the sheave case, swing drive, cylinder, reeving arrangement, cab/platform, electric swivel, hydraulic power unit, and load moment indicator (LMI) system. The manual provides exploded view diagrams for each major assembly, showing how individual parts fit together, and includes notes on part interchangeability, installation procedures, and specific part characteristics like "not sold separately" items. The technical documentation is intended to support maintenance, repair, and parts replacement for the DT50-55 crane model.

7.2.5 Description

This column lists the item nomenclature along with those modifiers necessary to identify the item. Additionally, cross references for repairable subassemblies are listed in this column.

One dot preceding the description indicates that the item is a component part of the previously listed item or assembly with no dot. Two dots indicate that the item is part of the previously listed item with one dot.

Example:

Electric Swivel . Collector Ring Assembly . . Screw . . Brush Holder Assembly . . . Brush Spring

The Collector Ring Assembly is a first level subassembly of the Electric Swivel as indicated with one dot. The Screw and the Brush Holder Assembly are second level components of the Collector Ring Assembly as indicated by the two dots. The Brush Spring is a third level component of the Brush Holder Assembly which is indicated with three dots.

7.3.6 Illustrations

Parts location illustrations may differ from engineering drawings because they have been altered to fit on the page or to improve clarity by omitting items that are not replaceable components such as weld-ons.

7.1 INTRODUCTION

This illustrated parts list contains all components of the crane that can be separately identified as well as parts necessary for equipment support.

7.1.1 Major Subassemblies

Figure 7-2 and Table 7-1 identify all major subassemblies of the crane. Quantities indicated are total per crane except indented items which indicate total per subassembly.

Equipment specifications (such as power requirements, dimensions, etc.) for major subassemblies are contained in Chapter 1.

7.1.2 Special Notes

Essential information regarding the interchangeability of parts, initial condition settings or special installation procedures are offset in italicized text in the parts breakdown illustrations when necessary.

7.2 FORMAT

Component parts lists (Pages 7‑8 through 7‑94) are presented in 5-column format.

7.2.1 Item

Index numbers found in this column correspond to the numbers found on the respective parts location illustration.

Some items are shown for reference purposes only to illustrate their relationship to other systems.

7.2.2 Notes

This column identifies footnotes applicable to specified items.

7.2.3 ASC P/N

This column lists the Allied Systems Company Part Number.

7.2.4 Qty

This column lists the total number of a specific item required per assembly or subassembly. This number may not necessarily be the number of items used in the end item or system. Only one set of components is listed whenever the components of two assemblies are the same.

“A/R” (as required) identifies bulk items whose length or other dimension must be specified when requisitioning.

“Ref” identifies items shown for reference purposes only to illustrate their relationship to other systems.

“NSS” (not sold separately) identifies items such as valve housings and spools, ring gears and pinions, etc., which must be ordered as a set because they are closely mated at manufacture.
