70 Tons Overhead Crane Core Features & সুবিধা

• 1. উচ্চতর লোড-ভারবহন ক্ষমতা: Rated lifting capacity of 70 টন, with a reinforced main beam and high-strength steel structure that undergoes strict quality testing (including non-destructive testing) to ensure stable operation under full-load conditions. The optimized beam design effectively distributes load stress, reducing deformation and extending service life.
• 2. সুনির্দিষ্ট & Efficient Control System: একটি পরিবর্তনশীল ফ্রিকোয়েন্সি ড্রাইভ দিয়ে সজ্জিত (ভিএফডি) system that enables smooth acceleration and deceleration, minimizing load sway and ensuring precise positioning of heavy loads. The control mode supports both cabin operation and remote control, allowing operators to choose the most convenient way based on on-site conditions, improving operation efficiency and safety.
• 3. ব্যাপক নিরাপত্তা সুরক্ষা: Integrated with multiple safety devices, ওভারলোড সুরক্ষা সহ, ঊর্ধ্ব/নিম্ন সীমা সুইচ, জরুরী স্টপ বোতাম, anti-collision device, and voltage protection. These devices form a multi-layered safety barrier to prevent accidents caused by operational errors or equipment malfunctions, safeguarding personnel and on-site assets.
• 4. টেকসই & কম রক্ষণাবেক্ষণ নকশা: মূল উপাদান (যেমন মোটর, হ্রাসকারী, and hooks) are sourced from well-known brands, ensuring high reliability and wear resistance. The sealed design of the transmission system prevents dust and debris from entering, reducing maintenance frequency and operational costs. উপরন্তু, the crane is designed with easy access to components for convenient inspection and maintenance.
• 5. Customizable Configuration: Based on the specific needs of different industries and working environments, we offer customizable options for span (10m-30m), উত্তোলন উচ্চতা (12m-24m), and auxiliary devices (such as grabs, electromagnetic suckers). This flexibility ensures the crane perfectly adapts to various operational scenarios.

70 Tons Overhead Crane Technical Parameters

Structural Composition of 70 টন ডাবল গার্ডার ওভারহেড ক্রেন

• 1. Main Girders: As the core load-bearing structure, the double main girders are made of high-strength Q355B steel, welded with advanced submerged arc welding technology. The box-type cross-section design enhances rigidity and load-bearing capacity, ensuring stable operation under heavy loads. Each main girder undergoes strict stress relief treatment to eliminate welding residual stress and prevent deformation.
• 2. End Girders: Connected to both ends of the main girders, the end girders are responsible for supporting the entire crane and connecting the traveling mechanism. They are designed with a rigid structure to ensure the overall stability of the crane during horizontal movement. The connection between end girders and main girders adopts high-strength bolts for reliable fixation.
• 3. Trolley Assembly: Composed of trolley frame, উত্তোলন প্রক্রিয়া, and trolley traveling mechanism. The lifting mechanism includes hoist, তারের দড়ি, ক্রেন হুক, and pulley block, which realizes the lifting and lowering of heavy loads. The trolley traveling mechanism drives the trolley to move along the track on the main girders, enabling lateral positioning of loads.
• 4. Crane Traveling Mechanism: Installed on the end girders, it consists of motors, হ্রাসকারী, চাকা, এবং ব্রেক. This mechanism drives the entire crane to move along the ground track, realizing long-distance transportation of loads. The adoption of frequency conversion speed regulation ensures smooth start and stop, reducing impact on the track and structure.
• 5. Electrical Control System: Includes control cabinet, operation console (cabin or remote control), frequency converter, যোগাযোগকারী, এবং সেন্সর. It is the “brain” of the crane, responsible for controlling the operation of each mechanism, realizing functions such as lifting, কমানো, trolley traveling, and crane traveling. একই সময়ে, it is integrated with safety protection devices to ensure safe and reliable operation.
• 6. নিরাপত্তা ডিভাইস: In addition to the safety protection components integrated in the electrical system, the structural safety devices also include rail clamps (to prevent crane sliding during power failure), buffer devices (to absorb impact energy during collision), এবং অ্যান্টি-রেইলমেন্ট ডিভাইস (to ensure the wheels run stably on the track).
