Product Descriptions
Plastic Injection Molding Gruniverpal Mini Cranes | Technical Details, Models, and Capacities
Mini Cranes for Plastic Injection Molding Machines manufactured by GT Cranes (Gruniverpal) are mobile crane solutions specifically designed for lifting, handling, and precise positioning of molds in plastic injection molding machines. These cranes enable safe, controlled, and highly accurate lifting operations in confined areas around injection machines where forklifts or overhead cranes cannot reach. The product range covers a very wide capacity spectrum, starting from 300 kg and extending up to 50,000 kg, making the systems suitable for both light-duty and heavy-duty applications.
In general, these cranes are equipped with wire-rope electric drive systems, telescopic boom extension options, mobile wheeled transportation, and proportional control systems. These features provide both high operational safety and maximum flexibility for the operator.

Operating Principle and Technical Advantages
• Mobile and wheeled design: Cranes are typically equipped with polyurethane or high-strength wheels, enabling easy maneuvering in confined spaces.
• Electric or hydraulic drive: The combination of electric motors and hydraulic pumps ensures controlled and precise lifting operations.
• Telescopic boom: Provides extended reach and allows operation at different working heights.
• Overload and safety systems: Integrated overload protection, automatic braking, and stabilization systems enhance operational safety.
• Flexible control: Proportional hand controls and optional remote control options ensure high positioning accuracy.
Application Areas
• Plastic injection molding machines: Mold loading, unloading, and precise positioning.
• Foundry and press lines: Heavy mold change operations.
• Maintenance and overhaul: Fast and safe intervention during equipment and mold updates.
• Confined space applications: Mobile crane solutions for areas inaccessible to forklifts.
