     Core Structural Components

• Steel Gantry Structure: Utilizes a dual-girder design. All steel plates undergo pre-treatment involving sandblasting for rust removal, primer application, and primer drying. This process effectively eliminates internal stresses in the steel, enhances paint adhesion, and ensures structural appearance quality and corrosion resistance. The upper gantry features a U-shaped opening design, providing ample working space and accommodating a trolley maintenance frame for convenient equipment servicing. The crane travel mechanism employs dual-flange wheels with surface-hardened treads achieving a hardness of HB320–350 and a hardened depth exceeding 15mm. Paired with premium rolling bearings, this ensures smooth operation and extended service life.
• Hoisting Mechanism: Equipped with a high-precision hoisting winch system utilizing premium steel wire ropes and rolled sheaves. Gear tooth surfaces achieve a hardness of no less than 50 HRC with an effective hardening depth exceeding 2mm, delivering high transmission precision and robust load-bearing capacity. Telescopic lifting attachments can be configured per operational requirements, supporting single- or double-container lifting. Rated lifting capacities under the attachment span multiple specifications including 35t, 40.5t, and 50t, accommodating diverse container weight demands.
• Travel Mechanism: Includes traverse and gantry travel mechanisms. The traverse can feature a rotating design or be equipped with a rotating lifting device, enabling the entire crane to operate through portal legs. This significantly expands the working range and enhances operational flexibility. Travel speeds are precisely controllable: hoisting speed 0–20 m/min, traverse speed 0–30 m/min, gantry travel speed 0–40 m/min, adapting to different operational rhythms.
• Electrical Control System: Utilizes PLC centralized control technology for intuitive operation and precise regulation, enabling automated coordination of all mechanisms. Electrical components feature renowned brands, with power supply compatible with AC 380V 50Hz three-phase electricity (customizable to other standards). Comprehensive electrical protection devices ensure power safety and stable system operation.
• Safety Protection System: Equipped with comprehensive safety devices including load cells (overload protection), lightning arresters, anchoring devices, rail clamps, and wind guy wires. Effectively handles overloads, high winds, and other adverse conditions to maximize operator and equipment safety. Conforms to GB 14734 “Safety Regulations for Port Rail-mounted Container Gantry Cranes,” incorporating comprehensive limit switches, buffers, and other protective functions.
