Manitowoc 777 Liftcrane Parts Manual Serial 7771160 PDF

The Manitowoc 777 Liftcrane Parts Manual Serial 7771160 PDF is a serial-number-specific parts reference for the Model 777 Liftcrane, Series 2. The machine record identifies S.O. 7723, serial number 7771160, and a January 2011 shipment date. Across 628 pages, the manual organizes illustrated assemblies, part numbers, quantities, drawing revisions, installation notes, and machine data around the rotating structure, upperworks machinery, controls and electrical systems, power plant, lowerworks, attachments, and referenced purchased components.

This manual is particularly useful when the exact crane configuration matters. The basic specification pages identify the installed QSL9−T3 power plant and engine serial number 73131377, the crawler arrangement, counterweights, boom and jib rigging, and wire-rope information before the parts sections begin. That gives parts personnel and technicians a machine-specific starting point instead of relying only on a generic Model 777 reference.

Machine Configuration Recorded in the Manual

The front specification sheets tie this parts book to a defined 777 Liftcrane configuration. The power plant is listed as QSL9−T3, engine serial number 73131377. The crawler is shown with a 24’−9″ length and 48″ tread. The upper counterweight assembly is identified as 197010 with a listed total weight of 142,700 lb, while the carbody counterweight is identified as 178275 with a total weight of 44,000 lb.

Boom data identifies rigging assembly 178288 with Boom Type #78 and a 210 ft boom configuration. The boom data lists a 22’−6″ butt, 37’−6″ top, 10 ft, 20 ft and 40 ft inserts, and the associated pendant lengths. The mast is identified as 178695−2. Jib data identifies rigging assembly 179331, Jib Type #134, with a 60 ft jib using a 15 ft butt, 15 ft top, 10 ft and 20 ft inserts and a 12’−6″ strut. The same opening data records a 1200 ft 1″ DYFORM 34LR MAX lift load line, an 890 ft 1″ DYFORM 34LR MAX lift whip line, 140 ft of 1″ mast rigging, a 15 ton hook and weight ball, and a 45 ton hook block.

Illustrated Parts and Assembly Reference

The Manitowoc 777 serial 7771160 parts manual is built around drawing-based identification. Assembly sheets pair illustrations or exploded views with item numbers, part numbers, quantities, descriptions, revision information, and notes. Examples include the operator’s cab, rotating bed, counterweight handling system, drum shaft, swing drive, hydraulic reservoir, drum brakes, control consoles, electrical harnesses, crawler components, boom and jib hardware, and attachment systems.

Many drawings also carry useful service details directly beside the parts information. The drum shaft pages, for example, include fastener torque values, thread-locking instructions, bearing-retainer installation notes and encoder installation clearances. Swing-drive information includes installation torques and gear-set backlash data. Drum-brake pages show initial brake assembly and adjustment guidance. Other sections identify hydraulic hose routing, valve arrangements, electrical wiring, connectors, pressure-related components, and assembly-specific cautions. These details help connect a part number to its actual location, mating hardware and installation context.

Each main section is arranged numerically and followed by an alphabetical index, while the back of the manual includes indexing for Groups A through F and the O-number material. That structure makes it practical to move from a system or assembly name to the relevant drawing and then to the itemized parts list. The early specification and weight pages also provide crane dimensions, component weights and configuration references that help distinguish the serial-specific machine from other 777 arrangements.

Built for Accurate Parts Identification

For a crane with serial number 7771160, this parts book supports more than simply looking up a component name. It can be used to identify assemblies and subassemblies, match item callouts to part numbers, verify quantities, trace hose and wiring locations, compare optional versus standard arrangements where shown, and review installation notes before disassembly or reassembly. Repeated instructions to provide the machine serial number when ordering reinforce the importance of matching parts to the actual crane configuration.

The drawing revisions in the book span many component updates, including late revisions to the counterweight, carbody, crawler, control wiring, boom rigging and attachment drawings. For technicians maintaining an older crane, those drawing-specific revisions and replacement notes can be important when a later component supersedes an earlier part or when a subassembly has more than one configuration.
