Description
The Double Girder Truss Gantry Crane is an efficient lifting system composed of a sturdy gantry frame, hoisting trolley, travelling mechanism, operator cabin, and electrical control system. Designed with an advanced open-truss layout, this double girder truss gantry crane delivers lightweight construction, superior wind resistance, and excellent overall stability for demanding outdoor material handling operations.
Core Structure & Engineering Advantages
The gantry framework integrates a main girder, upper end carriage, support legs, lower end beam, travelling bogies, maintenance walkway, and safety guardrails. Key structural features include:
-
Triangular Truss Main Girder: Features a high-strength triangular layout with top-mounted rails, enabling smooth transverse movement for the hoisting trolley.
-
Welded Truss Support Legs: Fabricated from structural steel sections to drastically reduce total dead weight while maintaining maximum load-bearing capacity.
-
Low Wind-Resistance Profile: The open lattice design minimizes wind resistance, preventing structural drag during harsh weather conditions.
-
Safe Maintenance Walkway: Outfitted with protective guardrails to allow convenient routine inspection and secure electrical equipment access.
Thanks to its lightweight design and durable construction, the double girder truss gantry crane is an ideal, cost-effective solution for shipyards, steel yards, precast yards, and high-wind outdoor environments.
