Link Belt HSP-8055 Crane Service Pdf Manual
Link-Belt HSP-8055 Crane Service PDF Manual
Built to handle demanding lifting applications where both reach and lifting capacity matter, the Link-Belt HSP-8055 combines a 55 U.S. ton (49.9 metric ton) rated capacity with a fully synchronized telescopic boom, heavy-duty hydraulic system and four-wheel-drive rough terrain carrier. Designed for refinery turnarounds, steel erection, heavy industrial construction, power generation projects and infrastructure development, the HSP-8055 became one of Link-Belt's most capable rough terrain cranes of its era. This OEM Factory Service PDF Manual provides the detailed repair procedures, specifications and diagnostic information required to overhaul, inspect and test the crane to factory standards.
About the Link-Belt HSP-8055
The HSP-8055 was engineered for contractors requiring greater lifting performance without moving to a larger truck crane. Its fully synchronized four-section boom extends from approximately 33 ft to 105 ft, while optional 33 ft and 58 ft lattice jibs increase maximum lifting height for specialized applications. A planetary swing system, hydraulic hoists and multiple steering modes allow the crane to work efficiently on confined and uneven jobsites.

Workshop Insight
The HSP-8055 introduced one of Link-Belt's most refined synchronized boom systems in the HSP family. During complete rebuilds, experienced crane technicians generally inspect boom synchronization, extension cylinders, swing bearings, planetary hoists and hydraulic pumps together because these systems work as an integrated lifting package. The factory service manual provides inspection tolerances, adjustment procedures and testing methods that help restore lifting accuracy while extending component life.
