70 톤 오버헤드 크레인

As a professional heavy-duty material handling equipment, 그만큼 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, 이것 오버헤드 크레인 delivers exceptional load-bearing capacity, 정밀한 제어, 그리고 믿을 수 있는 성능, making it an indispensable asset in industries requiring efficient and safe handling of ultra-heavy loads.

70 톤 오버헤드 크레인 핵심 기능 & 장점

• 1. 우수한 내하중 용량: 정격 리프팅 용량 70 톤, with a reinforced main beam and high-strength steel structure that undergoes strict quality testing (비파괴검사를 포함한) to ensure stable operation under full-load conditions. The optimized beam design effectively distributes load stress, reducing deformation and extending service life.
• 2. 정밀한 & Efficient Control System: 가변 주파수 드라이브 장착 (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. 포괄적인 안전 보호: Integrated with multiple safety devices, 과부하 보호 포함, 상하한 스위치, 비상 정지 버튼, 충돌 방지 장치, 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. 튼튼한 & Low-Maintenance Design: 주요 구성 요소 (모터와 같은, 감속기, 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. 추가적으로, the crane is designed with easy access to components for convenient inspection and maintenance.
• 5. 맞춤형 구성: Based on the specific needs of different industries and working environments, we offer customizable options for span (10m-30m), 리프팅 높이 (12m-24m), 및 보조 장치 (such as grabs, 전자기 빨판). This flexibility ensures the crane perfectly adapts to various operational scenarios.

70 톤 오버헤드 크레인 기술 매개변수

Structural Composition of 70 톤 더블 대들보 오버헤드 크레인

• 1. 주요 대들보: 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, 와이어 로프, 크레인 후크, 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, 감속기, wheels, 그리고 브레이크. 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, 저하, 트롤리 여행, and crane traveling. At the same time, it is integrated with safety protection devices to ensure safe and reliable operation.
• 6. 안전장치: 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).
