Large-Diameter Crane Guide Wheels for Container Stacker Vertical Alignment
Item | Details |
|---|---|
Material | Medium-high carbon steel (e.g., 1045, 1055) – Chosen for an optimal balance of strength, toughness, and wear
resistance to withstand the high vertical loads and guide rail
contact stresses during container stacker operations. |
Design Feature | Large-diameter profile with deep flange – The increased diameter provides superior stability and
resistance to tipping, while the deep, precisely-contoured flange
ensures secure engagement with the vertical guide rail, maintaining
perfect stacker alignment. |
Main Application | Exclusively engineered for the vertical alignment systems of
container stackers and Rail-Mounted Gantry Cranes (RMGs) – Critical for ensuring straight, precise vertical travel in port
terminals, intermodal yards, and automated storage facilities. |
Production Process | Forging (for core strength) → Precision machining → Heat treatment
(flange hardening) – Forging ensures a defect-free core, while subsequent processes
achieve the exact geometry and localized hardness needed for
reliable guide rail contact. |
Inspection Focus | Flange profile accuracy, surface hardness mapping, and
non-destructive testing (MT/PT) – Rigorous checks ensure the flange geometry perfectly matches the
guide rail, hardness is consistent, and no surface cracks exist to
compromise safety. |
Service Package | Tiangong provides application-specific design consultation, batch
production with strict traceability, and comprehensive technical
documentation – Ensures seamless integration into container stacker alignment
systems and compliance with port equipment standards. |
