Their wide lifting capacity, powerful hydraulic system, and mobile/foldable design provide high functionality and ease of use for crane operators.
Series and Capacities
The Gruniverpal Electric / Semi-Automatic Mini Cranes product range is mainly offered under the JT-LINE series with different capacity options:
• JT400_TR – Mini crane with a lifting capacity of up to 400 kg.
• JT450_TR – Mid-range mini crane with a lifting capacity of up to 450 kg.
• JT600 – Professional mini crane solution with a lifting capacity of up to 600 kg.
These series offer high lifting capacity and versatile usage with a relatively low investment cost.
Design Features and Structure
Gruniverpal mini cranes stand out with the following technical and structural features:
Compact and Mobile Design
• Compact construction allows easy maneuvering even in confined spaces.
• Portable and foldable design provides easy storage and flexible use in different working areas.
• Operator-friendly use thanks to unique control handles and brake design.
Hydraulic System and Performance
• Fast and easy lifting is achieved through a double-acting hydraulic pump.
• The hydraulic system also allows close-range positioning of the crane around machines or work areas.
• All components are tested with a 25% overload before delivery, ensuring durability and safety beyond standard operating limits.
Durability and Warranty
• A 12-month warranty is standard for all mini crane components.
• The counter-balanced design optimizes crane stability, minimizing the risk of imbalance, especially in machine-side applications.
