30 Tons Double Girder EOT Crane

The 30 tons double girder Electric Overhead Traveling (EOT) crane is a heavy-duty industrial material handling solution designed for high-load, high-efficiency, and long-cycle lifting operations. Adopting a robust double box girder structure and advanced electric drive system, this crane delivers superior load-bearing capacity, operational stability, and working coverage compared with single girder EOT cranes. It is engineered to handle 30-ton heavy loads steadily and precisely, widely applicable for material lifting, equipment installation, cargo handling, and workshop turnover in heavy industrial scenarios. Complying with ISO, CE and national industrial crane standards, the whole machine features reliable quality, long service life and flexible customization, becoming the core lifting equipment for modern heavy manufacturing workshops.

30 Tons Double Girder EOT Crane Core Structural Features

The 30-ton double girder EOT crane adopts a mature and optimized double parallel box girder main structure, with integral welded steel structure that undergoes strict stress elimination treatment, effectively avoiding structural deformation and fatigue damage during long-term heavy-load operation. The double-girder load-sharing design disperses bearing pressure evenly, greatly improving the overall rigidity, stability and seismic performance of the equipment, enabling it to adapt to large-span and high-lifting working conditions that single-girder cranes cannot support.

Equipped with a dedicated electric trolley running on the top of the double girders, the crane achieves flexible transverse and longitudinal movement. The trolley integrates high-performance lifting mechanism, running mechanism and braking system, with compact structure and high transmission efficiency. The whole machine adopts modular assembly design, which simplifies installation, disassembly and daily maintenance, and effectively reduces later operation and maintenance costs. In addition, the reserved installation space supports the subsequent upgrade of intelligent control and automatic positioning systems.

Superior Product Advantages

Excellent Load-bearing & Structural Stability

The high-strength box-type double girder structure realizes uniform load distribution, with strong impact resistance and overload resistance. It can maintain stable operation under full-load and frequent start-stop working conditions, without shaking or offsetting, ensuring the safety of heavy-load lifting operations. The optimized structural design extends the service life of the whole machine to more than 15 years under normal working conditions.

High Operational Efficiency & Precision

Matched with high-efficiency electric hoist and variable frequency drive system, the crane realizes stable start, stepless speed regulation and accurate positioning, effectively avoiding cargo swing and positioning deviation during operation. The flexible dual-direction traveling mechanism covers a large working area, greatly improving the turnover efficiency of workshop materials and shortening the working cycle of heavy equipment handling.

Comprehensive Safety Protection

The equipment is equipped with a complete set of safety protection devices, including overload limiter, height limit switch, travel limit device, emergency stop button, buffer anti-collision device and brake self-locking system. All electrical components adopt well-known brand parts with stable performance and low failure rate. The IP54 protection grade adapts to complex industrial environments such as dust, humidity and slight corrosion, effectively reducing equipment failure risks and ensuring zero safety accidents in operation.

Low Maintenance & Strong Adaptability

Modular and standardized component design makes daily inspection, replacement and maintenance of parts more convenient, greatly reducing equipment downtime and maintenance costs. The whole machine can be customized according to user’s workshop span, lifting height, working frequency and environmental conditions, supporting fixed-speed, variable-frequency, remote control, cab control and other operation modes, with strong environmental adaptability and scene compatibility.

Application Scenarios

The 30 tons double girder EOT crane is a versatile heavy-duty lifting equipment, widely used in various heavy industrial fields with high load and high working frequency requirements. Typical application scenarios include machinery manufacturing workshops, steel structure processing plants, metallurgical workshops, construction material warehouses, hydraulic engineering bases, port freight yards, and large equipment maintenance bases. It is specially suitable for regular heavy-load lifting, precise equipment installation and batch material handling operations, and is an essential core equipment to improve industrial production automation and operational efficiency.
