As a professional heavy-duty material handling equipment, тот 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, этот мостовой кран delivers exceptional load-bearing capacity, точный контроль, и надежная работа, making it an indispensable asset in industries requiring efficient and safe handling of ultra-heavy loads.

70 Основные характеристики мостового крана тонн & Преимущества
- 1. Превосходная несущая способность: Rated lifting capacity of 70 тонны, 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. Precise & Efficient Control System: Оборудован частотно-регулируемым приводом. (ЧРП) 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. Комплексная защита безопасности: Integrated with multiple safety devices, включая защиту от перегрузки, upper/lower limit switches, кнопка аварийной остановки, 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. Durable & Low-Maintenance Design: Ключевые компоненты (такие как моторы, редукторы, 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. Кроме того, the crane is designed with easy access to components for convenient inspection and maintenance.
- 5. Настраиваемая конфигурация: Based on the specific needs of different industries and working environments, we offer customizable options for span (10m-30m), высота подъема (12m-24m), и вспомогательные устройства (such as grabs, электромагнитные присоски). This flexibility ensures the crane perfectly adapts to various operational scenarios.

Structural Composition of 70 Тонн двухбалочный мостовой кран

- 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, подъемный механизм, и механизм перемещения тележки. The lifting mechanism includes hoist, wire rope, Крюк Крюк, 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, редукторы, wheels, и тормоза. 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. Электрическая система управления: Includes control cabinet, operation console (cabin or remote control), преобразователь частоты, contactors, and sensors. Это «мозг» крана, responsible for controlling the operation of each mechanism, realizing functions such as lifting, опускание, троллейбус путешествует, and crane traveling. At the same time, it is integrated with safety protection devices to ensure safe and reliable operation.
- 6. Устройства безопасности: 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), и противосходные устройства (to ensure the wheels run stably on the track).
