70 Ton double girder gantry crane

Manufactured in strict accordance with international ISO and CE safety standards, the 70-ton double girder gantry crane features optimized mechanical structure, intelligent control system, and reliable safety protection devices, ensuring long-term stable operation under harsh working conditions such as high load, ধুলো, and variable weather. It balances high working efficiency, অপারেশনাল নিরাপত্তা, এবং শক্তি সঞ্চয় কর্মক্ষমতা, meeting the heavy-duty production demands of modern industrial enterprises.

মূল কাঠামোগত বৈশিষ্ট্য

1. Optimized Double Girder Main Structure

The crane adopts a high-strength box-type double girder structure, which effectively disperses heavy load pressure and reduces structural deformation during long-span operation. Compared with single girder gantry cranes, the double girder design greatly improves overall rigidity, bending resistance, and torsional resistance, ensuring no obvious deflection under full-load 70-ton working conditions. The main girder is made of high-quality low-alloy structural steel, with integral welding and stress relief treatment, effectively eliminating internal structural stress and extending the service life of the equipment. The standardized walking platform, safety guardrails, and maintenance ladders are installed on the top of the main girder, facilitating daily inspection and maintenance for operators.

2. Stable Support and Traveling Mechanism

Equipped with reinforced rigid or flexible outriggers, the crane realizes stable gantry framing and uniform load distribution. The flexible outrigger design can effectively buffer structural stress caused by temperature changes and operational vibration, avoiding structural damage and improving overall operational stability. The traveling mechanism adopts heavy-duty track wheels and high-precision drive motors, matching standard railway rails or custom heavy-duty rails. It realizes smooth linear traveling with low noise and low friction, ensuring accurate positioning during long-distance material handling.

3. High-Performance Lifting Trolley

The matched heavy-duty lifting trolley is equipped with a professional 70-ton grade hoisting mechanism, কম্প্যাক্ট গঠন সমন্বিত, শক্তিশালী ওভারলোড প্রতিরোধের, এবং উচ্চ সংক্রমণ দক্ষতা. The trolley supports transverse traveling along the main girder, cooperating with the crane’s longitudinal traveling to realize three-dimensional flexible operation. The low-clearance trolley design maximizes the effective lifting height and expands the operating space, adapting to various complex on-site working conditions.

Outstanding Product Advantages

1. Super Heavy Load Capacity and High Stability

একটি রেট উত্তোলন ক্ষমতা সঙ্গে 70 টন, this double girder gantry crane easily copes with ultra-heavy material handling tasks. The scientific double girder structural layout ensures small structural deformation and strong anti-vibration ability during full-load operation, with accurate lifting and positioning, effectively avoiding load shaking and offset, and improving the safety and accuracy of heavy object handling.

2. Smooth and Efficient Operation

Adopting advanced variable frequency speed regulation (ভিএফডি) নিয়ন্ত্রণ ব্যবস্থা, the crane realizes stepless speed adjustment for lifting, ট্রলি ভ্রমণ, এবং ক্রেন ভ্রমণ. It effectively solves the problems of start-stop impact and load jitter of traditional cranes, making the whole operation process stable and smooth. The intelligent control mode improves working efficiency by 20%-30% compared with ordinary cranes, suitable for high-frequency continuous lifting operations.

• ◆ Overload protection device: Automatically cut off the lifting power and trigger an alarm when the load exceeds the rated 70 tons to prevent overload operation accidents;
• ◆ Height limit device: Set upper and lower limit protection for lifting stroke to avoid equipment damage caused by over-winding and over-releasing of steel wire ropes;
• ◆ Travel limit device: Install limit switches at both ends of the track to prevent the crane and trolley from derailing and collision caused by over-traveling;
• ◆ উইন্ড-প্রুফ এবং অ্যান্টি-স্লিপ ডিভাইস: Equipped with professional wind-proof clamps and rail brakes, which can firmly fix the crane on the track in strong wind weather to avoid sliding and overturning;
• ◆ Emergency stop system: Equipped with manual emergency stop buttons in the operating room and remote control terminal, which can quickly cut off all power in case of abnormal conditions;
• ◆ Real-time monitoring system: Optional intelligent monitoring module, which can real-time display operating parameters such as load, উচ্চতা, traveling speed, and equipment operation status, and record operation data for safety traceability.
