70 تن جرثقیل سقفی

به عنوان یک تجهیزات حرفه ای حمل و نقل مواد سنگین, را 70 tons overhead crane is engineered to meet the rigorous demands of large-scale industrial lifting operations. Designed with advanced technology and robust structural design, این جرثقیل سقفی delivers exceptional load-bearing capacity, precise control, و عملکرد قابل اعتماد, making it an indispensable asset in industries requiring efficient and safe handling of ultra-heavy loads.

70 تن ویژگی های هسته جرثقیل سقفی & مزایا

• 1. Superior Load-Bearing Capacity: ظرفیت بلند کردن امتیاز از 70 تن, with a reinforced main beam and high-strength steel structure that undergoes strict quality testing (از جمله آزمایش های غیر مخرب) to ensure stable operation under full-load conditions. The optimized beam design effectively distributes load stress, reducing deformation and extending service life.
• 2. دقیق & Efficient Control System: Equipped with a variable frequency drive (VFD) 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. حفاظت جامع ایمنی: Integrated with multiple safety devices, از جمله حفاظت از اضافه بار, سوئیچ های حد بالا/پایین, دکمه توقف اضطراری, 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. بادوام & Low-Maintenance Design: اجزای کلیدی (such as motors, کاهنده ها, 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. علاوه بر این, 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), ارتفاع بلند کردن (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 تن جرثقیل سقفی دو تیر

• 1. تیرهای اصلی: 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, lifting mechanism, and trolley traveling mechanism. The lifting mechanism includes hoist, سیم طناب, قلاب, 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, کاهنده ها, wheels, و ترمز. 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, contactors, and sensors. It is the “brain” of the crane, responsible for controlling the operation of each mechanism, realizing functions such as lifting, پایین آوردن, سفر واگن برقی, and crane traveling. در عین حال, it is integrated with safety protection devices to ensure safe and reliable operation.
• 6. دستگاه های ایمنی: 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), and anti-derailment devices (to ensure the wheels run stably on the track).
