Used SANY STB550T5-8 Crawler Crane 55 t Capacity 62 m Lattice Boom Hydraulic Tracked Lifting Equipment
Used SANY STB550T5-8 Crawler Crane Product Description
This pre-owned SANY STB550T5-8 crawler crane is a large-capacity crawler crane purpose-built for heavy industrial lifting, wind turbine erection support, and petrochemical plant construction. Powered by a 360HP Weichai WP12G360E302 Diesel diesel engine and riding on a robust crawler undercarriage, this crane delivers exceptional lift capacity and on-site mobility across unprepared ground conditions. The lattice boom configuration provides a 62 m maximum boom length, while the full-power hydraulic system ensures smooth and precise load control during lifting, slewing, and luffing operations. This crane has been utilized in general construction and infrastructure lifting applications, with periodic maintenance and load-testing records available for review. It represents a practical investment for contractors seeking tracked crane capability for foundation work, steel erection, precast concrete placement, and heavy industrial component installation.

Crane Condition & Load Test Verification
This SANY STB550T5-8 crawler crane has received a thorough inspection encompassing structural, mechanical, hydraulic, and safety systems. The lattice boom chord members and lacings were visually inspected for straightness, corrosion, and weld integrity — no deformation or crack indications were identified. Boom pivot pins and boom foot connections were examined with no excessive wear measured by micrometer. The main hoist and boom hoist wire ropes were inspected over full length per ISO 4309 with no more than 3 broken wires in any single lay length. The hook block assembly was inspected for throat opening wear, swivel function, and safety latch operation — all passing. The crawler track chains, sprockets, idlers, and rollers show normal wear with track tension adjustment remaining within range. Hydraulic cylinders for boom hoist and luffing were checked with zero drift during a 20-minute static hold test at rated load. The rated capacity limiter and over-hoist limit switches were functionally tested and confirmed operational.
Crane Shipping & Heavy-Lift Logistics
Export of this crawler crane is arranged through break-bulk cargo service or on a flat-rack container combination, given the machine weight and dimensions exceed standard container capacity. The crane will be partially disassembled for transport: the boom sections will be separated and bundled, the counterweight slabs will be packed individually on timber dunnage with edge protection, and the crawler side frames may be detached from the carbody to reduce shipping width. All hydraulic hose quick-disconnects will be capped, electrical harnesses bagged and labeled, and exposed cylinder rods protected with anti-corrosion wrap. The machine serial number plate will be clearly photographed and documented. Complete export documents include commercial invoice detailing component count and weights, detailed packing list with crate/item manifest, certificate of origin, and ocean bill of lading. We work with project cargo freight forwarders specializing in crane logistics. Ocean transit estimates: Africa 25-35 days, Middle East 15-22 days, Southeast Asia 8-12 days, South America 28-38 days.
Post-Purchase Crane Support Services
Each crawler crane purchase includes the pre-delivery inspection certificate, boom assembly and erection manual, load chart booklet for all boom and jib configurations, and hydraulic/electrical schematics. We provide 7 days of remote support following shipment arrival to address any questions regarding crane reassembly sequence, boom section pinning procedure, hydraulic system commissioning, load moment indicator setup calibration, and functional test procedures prior to operational deployment. A recommended spare parts list covering hoist brake friction discs, hydraulic filter elements, boom pin keepers, wire rope clips, and slewing ring grease is provided. Through our crane parts supply network, we can facilitate orders for genuine or OEM-equivalent components with international shipping. We recommend the buyer engage a certified crane inspector for arrival inspection and commissioning verification before placing the crane into lifting service. This crane is sold as inspected used equipment.
