KINOCRANES Custom RTG Crane for Steel Coil Handling

Client Background: A leading steel mill in the United States required a material handling solution for their new steel coil warehouse. The facility presented significant spatial challenges: With a ceiling height of only 4.8 meters, a clearance of 4.39 meters beneath the steel structure, and a span of 5.79 meters between bays, coupled with the need to lift 21.5-ton steel coils, traditional overhead cranes were deemed unsuitable. KINOCRANES provided a tailored 21.5-ton Rubber Tired Gantry Crane (RTG Crane) solution, effectively addressing the mill's challenges and enhancing their operational efficiency.

Client Requirements:

• Safe and efficient handling of 21.5-ton steel coils within a height-restricted indoor space.
• High maneuverability of the RTG crane to navigate narrow spans.
• Precise C-hook lifting for stable coil handling.
• Increased overall handling efficiency and reduced labor/time costs.

Technical Challenges:

• Spatial Constraints: The low ceiling height (4.8m) and steel structure clearance (4.39m) imposed strict design limitations on the RTG crane.
• Heavy Lifting: Handling 21.5-ton coils demanded a Rubber Tired Gantry Crane with robust lifting capacity and stability.
• Precision Operation: Accurate C-hook positioning and agile controls were critical for safe and efficient operation in confined spaces.
• Indoor Operation: The RTG crane's tires needed to minimize floor pressure and eliminate exhaust emissions.

Solutions:

KINOCRANES delivered a custom-engineered RTG crane solution to address the steel mill's unique requirements:

• Compact RTG Crane Design:
  • Optimized lifting and travel mechanisms to minimize overall crane height.
  • Engineered a reduced profile boom design to further enhance operational clearance.
• Custom C-Hook for RTG Crane:
  • Designed and fabricated a high-strength, precision C-hook tailored to the coil dimensions and weight.
  • Integrated sensors for real-time coil monitoring to enhance safety during RTG crane operations.
• All-Wheel Steering RTG Crane:
  • Implemented an all-wheel steering system for exceptional maneuverability in tight spaces.
  • Equipped with high-quality industrial tires to ensure stable operation and minimize floor impact for the Rubber Tired Gantry Crane.
• Electric Drive RTG Crane:
  • Utilized an electric drive system for emission-free and low-noise indoor operation of the RTG crane.
• Enhanced Safety for RTG Crane:
  • Integrated overload protection, limit switches, and an emergency stop system.
  • Constructed with high-strength steel for structural integrity of the Rubber Tired Gantry Crane.

Implementation Process:

• Detailed data collection with client collaboration.
• Professional design and optimization by our engineering team.
• Rigorous manufacturing and quality control.
• Expert installation, commissioning, and operator training for the RTG crane.
