300 टन डबल गर्डर ओवरहेड क्रेन

उत्पाद अवलोकन

The 300 ton double girder overhead crane is a heavy-duty, high-efficiency industrial lifting equipment designed for ultra-heavy load handling in large-scale industrial scenarios. Manufactured in strict accordance with GB/T3811 national standards and European FEM, DIN industrial specifications, this crane integrates optimized structural design, mature frequency conversion control technology and comprehensive safety protection systems. It is specially developed to solve the lifting and transshipment demands of 300-ton super-heavy materials, equipment and components, featuring stable operation, मजबूत भार वहन क्षमता, high precision and excellent durability. As a core handling equipment for heavy industry, it can adapt to long-term continuous high-intensity operation and effectively improve industrial production and hoisting efficiency.

Core Structural Design

This double girder overhead crane adopts a mature and reliable box-type bias-rail double main girder structure, which is the key to realizing ultra-heavy load bearing. The two parallel high-strength box girders evenly disperse the heavy load, completely avoiding stress concentration and greatly improving the overall rigidity and stability of the equipment compared with single-girder cranes.

The main girders are connected with high-precision end beams via high-strength integral bolts. Processed by professional precision processing equipment, the connecting surfaces achieve high matching accuracy, ensuring no deviation during long-distance operation and smooth trolley traveling. The end beam adopts an integral torsion-resistant box structure, which effectively resists torsion and vibration during heavy-load operation and enhances the overall structural stability of the crane.

The complete equipment set includes main girders, अंत गाड़ियाँ, traveling operating mechanism, heavy-duty electric wire rope hoist trolley, electrical control system and multi-dimensional safety protection devices. The overall structure is compact and optimized, with reasonable force distribution, convenient disassembly, परिवहन और साइट पर स्थापना, and low later maintenance cost.

उत्कृष्ट उत्पाद विशेषताएँ

1. Super Strong Load-Bearing & स्थिर संचालन

2. Intelligent Variable Frequency Control & उच्चा परिशुद्धि

3. टिकाऊ & कम रखरखाव

4. ऊर्जा की बचत & जगह की बचत

Optimized lightweight structural design reduces the self-weight of the crane and wheel pressure on the factory building track, lowering the requirements for factory building bearing and track foundation. The compact overall structure makes full use of the vertical and horizontal space of the workshop, effectively saving plant space, while the efficient transmission system reduces energy consumption and realizes energy-saving and environmentally friendly operation.

व्यापक सुरक्षा सुरक्षा प्रणाली

Safety is the core design priority of the 300-ton heavy-duty overhead crane. The equipment is equipped with a full set of multi-layer safety protection devices to eliminate operational risks in all directions:

• ◆ Overload Limiter: Automatically cut off the power and trigger an alarm when the load exceeds the rated weight to prevent overload operation damage;
• ◆ Height Limit Device: Dual upper and lower limit protection to avoid collision and wire rope breakage caused by over-lifting or over-descending;
• ◆ Emergency Stop System: Equipped with manual and remote emergency stop buttons, which can quickly cut off the power supply in case of abnormal conditions to stop all actions;
• ◆ Anti-collision Device: Infrared anti-collision induction installed on both ends of the crane to avoid collision between multiple cranes or with workshop buildings;
• ◆ Phase Sequence & Overvoltage/Undervoltage Protection: Protect the electrical system from damage caused by abnormal power supply and ensure stable electrical operation;
• ◆ Rainproof & Dustproof Protection: All electrical components adopt closed protective design, adapting to indoor and semi-outdoor harsh working environments.
