Gruniverpal Mini Cranes for Tyre Moulding | Detailed Technical Lifting and Model Reviews
Mini Cranes for Handling Molds for the Production of Tyres manufactured by Gruniverpal (GT Cranes) are mobile crane solutions specifically designed for lifting, transporting, and positioning vulcanization press molds in the tyre production industry. These electric mini cranes are optimized to perform precise, controlled, and safe lifting operations even in confined spaces within tyre manufacturing lines. For this reason, they are preferred by many of the world's leading tyre manufacturers.
The mini cranes are designed with lifting capacities of up to 12,500 kg, covering the majority of tyre mold weights; in addition, smaller-capacity models are also available within the product range.
General Design and Performance Features
Gruniverpal tyre mold cranes generally stand out with the following technical features:
• Wide capacity range: lifting capacities starting from 100 kg up to 12,500 kg.
• Electro-hydraulic electric drive: all models are equipped with electrically driven hydraulic systems that provide powerful and controlled lifting performance.
• Mobile wheeled chassis: polyurethane or high-strength wheels ensure mobility and easy maneuvering in confined areas.
• Proportional control: controlled lifting and lowering systems enable millimetric precision during mold positioning.
• Telescopic boom and height adjustment: selected models offer telescopic boom extension for greater reach and operational flexibility.
• Safety systems: overload protection, automatic braking, and stabilization systems enhance operator safety.

Operating Principle and Operational Advantages
The basic operating principle of Gruniverpal tyre mold cranes is based on electric-hydraulic drive systems and a mobile wheeled chassis for lifting, transporting, and positioning molds within press lines. Thanks to proportional controlled lifting, mold movements are smooth and achieved with millimetric precision. In addition, magnetic brakes, overload protection, and stabilization systems ensure a high level of safety both in tyre production lines and during maintenance operations.
Application Areas
• Mold handling in tyre production machines: loading and unloading molds to and from vulcanization presses.
• Positioning in press lines: millimetric placement of large tyre molds.
• Maintenance and service: rapid mold change and part handling during production line maintenance.
• Mold logistics: safe internal transport and storage operations within production facilities.
