Technical Requirements & Manufacturing Standards
Important Engineering Standard Notes:
- Design & Manufacturing Codes: The design, manufacturing, installation, inspection, and acceptance of this crane shall strictly comply with the GB/T19683 national standard.
- Insulation Resistance Testing: When measuring the insulation resistance to ground and phase-to-phase resistance, the entire power circuit and control circuit of the crane must be connected across all lines, with a value of not less than 0.5M$\Omega$ (insulation resistance can be reduced by 50% in humid areas).
- Grounding Protection: The shells of all electrical equipment on the crane must be reliably grounded; crane tracks are permitted to be used for grounding, and the metal structure of the facility serves as a grounding conductor.
- Environmental & Brand Assurance: Specifically designed for severe outdoor environments (-40℃ to 40℃) with a 310m gantry travel length. Core cable reel motors utilize the Siemens brand to ensure long-distance power feeding safety and reliability.

Frequently Asked Questions (RMG50t-32m-12.5m Drawing Technical Analysis)
Professional insights addressing core highlights including the 32m span, 11m left cantilever, trolley-traveling cabin, and 310m travel length.
1. What are the advantages of the 11m ultra-long left cantilever and stack 4 over 5 yard layout?
The 11-meter left cantilever easily spans external truck lanes, access roads, or railway loading tracks outside the storage yard. Combined with the 32m main span, it achieves high-density storage capacity (stacking 4 containers high and passing over 5), significantly maximizing space utilization and turnover efficiency at terminals or freight yards.
2. Why choose an operator cabin that travels with the trolley, equipped with hollow insulated glass and HVAC?
Having the operator cabin move synchronously with the trolley grants the operator a direct, wide-angle line of sight right above the spreader and containers, eliminating visual blind spots. Combined with heating/cooling air conditioning, hollow insulated glass, and video monitoring systems, operators maintain supreme comfort and productivity even in extreme outdoor environments (-40℃ to 40℃).
3. What special configurations are applied to the cable reel for the 310-meter ultra-long travel distance?
Because the total gantry travel distance reaches 310 meters, the system utilizes a single-side power supply equipped with top-tier international Siemens cable reel drive motors. This ensures smooth cable winding and unwinding with constant tension during long-distance high-frequency back-and-forth travel, completely preventing cable wear or jamming faults.
4. How do full frequency conversion control and the anti-sway/weighing systems work together?
Full VFD speed control (hoisting 1.2~12 m/min, trolley 3.8~38 m/min, gantry 7.5~75 m/min) ensures stepless, smooth transitions during startup and stopping, minimizing mechanical shock. Integrated with built-in electronic anti-sway technology and dynamic weighing functions, the spreader quickly secures containers and accurately stacks them with utmost stability, safeguarding semi-automated and automated operations.
