从China供应商批量进口5t 20t 70m Tower Crane

The SCM-C7050 is a self-telescoping tower crane with maximum lifting capacity of 20 tonnes and jib radius reaching 70 metres, with a minimum load rating of 5 tonnes at maximum outreach. The luffing or saddle jib configuration allows height adjustment through an integrated telescoping mechanism without auxiliary climbing equipment. The structure is engineered for heavy civil construction including high-rise buildings, infrastructure bridges, and industrial projects where both reach and lift capacity are critical path factors.

The self-telescoping tower design enables incremental height increases as structure floors are completed, reducing downtime compared to external climbing systems that require crane disassembly and re-erection. The mechanism typically uses hydraulic or mechanical telescoping sections within the tower mast, allowing the crane to grow with the building. Stability is achieved through a combination of tower base anchorage, tie-in brackets to the structure at intervals, and counterweighted superstructure, though exact ballast weights and tie spacing are not stated in the source and require supplier confirmation.

Construction contractors, project developers, and rental fleet operators form the primary buyer segments for this class of tower crane. The 20 tonne maximum capacity suits prefabricated concrete element placement, steel frame erection, and heavy mechanical installation. The 70 metre jib covers large footprint sites without repositioning. Buyers should confirm with Sichuan Construction Machinery the specific load chart at varying radii, wind speed operational limits, and whether the foundation design is included or requires separate structural engineering.

Sichuan Construction Machinery (Group)Co., Ltd. is headquartered in Chengdu, Sichuan Province, China, with a postal address at P.O. Box 102, Dongzikou, Chengdu 610081. The company holds an imported supplier tier designation and a harbor trust tier on the platform. The response rate is recorded at 0.00 percent with zero average response hours, indicating buyers should not rely on rapid quotation turnaround and should plan for extended communication cycles or direct engagement through alternative channels.

The group manufactures and supplies construction machinery including tower cranes for domestic and export markets. The source description references international standards compliance and flexible procurement terms, though no specific ISO certifications, factory audit reports, or named client projects are provided in the data. No information on manufacturing floor area, annual crane output, or in-service fleet size is stated. Buyers should request directly from Sichuan Construction Machinery their CE marking status for European markets, type examination certificates under EN 14400 or EN 14439, and reference installations of the SCM-C7050 model specifically.
