Zomax 80 tons Double Girder Overhead Crane is a double girder crane developed using a electric hoist trolley with superior performance and advanced technology as the lifting mechanism. The lifting capacity is up to 80 tons. The crane features lightweight, modular and parametric design.
The crane travelling mechanism is powered by a three-in-one drive system and controlled by an advanced variable frequency speed control system. It provides a perfect combination of mechanical excellence, lifting intelligence and service support. It has superior performance, safety and reliability, energy saving and high efficiency. It is ideal for lifting and handling tasks in workshops, warehouses, and power stations.
The 80 Tons Double Girder Overhead Crane is a heavy-duty lifting solution designed for handling loads up to 80 tons. Developed by Zomax, it features an advanced electric hoist trolley, double girder structure for enhanced strength, and a three-in-one drive system with variable frequency control for smooth, precise operation. Its modular, lightweight design ensures high efficiency, safety, and reliability, making it ideal for workshops, warehouses, and power stations.
The 80 Tons Double Girder Overhead Crane operates through three coordinated movements to lift and transport heavy loads:
Lifting Movement:
The hoist trolley, powered by a single or double-speed motor, drives the steel wire rope and hook to raise or lower loads vertically (up to 40m).
Cross Travel:
The hoist trolley moves horizontally along the double box girders, enabling side-to-side load positioning across the crane span (up to 50m).
Long Travel:
The entire crane moves along rails installed on the runway beams, allowing forward and backward motion across the workshop or site.
These three motions work together to enable precise, efficient three-dimensional material handling. Powered by a three-in-one drive system and controlled via pendant, remote, or cabin, the crane ensures smooth operation, enhanced safety, and reliable performance under demanding industrial conditions.
The three-in-one drive overhead crane offers significant advantages over traditional cranes by reducing operational complexity and maintenance costs. By combining the motor, gearbox, and brake intoa single compact unit, this system delivers smoother operation, lower noise, and higher efficiency, making it an excellent choice for businesses looking to optimize their material handling operations.
The Zomax 80 tons double girder crane with three-in-one drive is the perfect solution for lifting heavy loads efficiently while maintaining the highest levels of safety, reliability, and energy savings.
1. Handling Heavy Loads with Safety Risks
Lifting capacity up to 80 tons, ideal for heavy-duty applications.
Equipped with anti-sway system, dual braking, and overload protection to ensure safe operations.
Smooth and precise control with frequency inverter and three-in-one drive system improves safety during load positioning.
2. Low Positioning Accuracy and Unstable Movement
Variable frequency drive (VFD) ensures soft start/stop, reducing sway and improving control precision.
The three-in-one drive system ensures smooth travel and high positioning accuracy.
Optional load sway control further enhances safety in precision handling environments.
3. Space Constraints and Low Headroom Issues
Compact box girder design allows installation in restricted vertical space.
Custom span and lifting height options allow for non-standard workshop configurations.
Low-headroom trolley ensures maximum use of lifting height.
4. High Energy Consumption and Maintenance Costs
Energy-efficient three-in-one drive units reduce power loss and wear.
Low maintenance components such as long-life brake pads, sealed motors, and alloy steel hooks.
Reduced downtime and operating costs due to modular, easily replaceable parts.
5. Industry-Specific Challenges and Harsh Environments
Highly customizable options: explosion-proof design, corrosion-resistant paint, outdoor-rated enclosures, high-temperature insulation.
Suitable for industries such as steel production, energy, construction, shipbuilding, and more.
Operates effectively in temperatures from -20°C to +60°C, indoors or outdoors.
6. Lack of Smart Monitoring and Preventive Maintenance
Smart monitoring system (optional) tracks overloads, lifting cycles, motor starts, and brake wear.
On-screen alerts and maintenance tips help with preventive servicing.
Enables integration with factory MES/ERP systems for digitalized operations and equipment health tracking.
