70 吨桥式起重机核心特点 & 优势
- 1. 卓越的承载能力: Rated lifting capacity of 70 吨, with a reinforced main beam and high-strength steel structure that undergoes strict quality testing (包括无损检测) 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: 配备变频驱动器 (变频驱动) 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. 全面的安全防护: Integrated with multiple safety devices, 包括过载保护, 上限/下限开关, 紧急停止按钮, anti-collision device, 和电压保护. 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. 耐用的 & Low-Maintenance Design: 关键部件 (例如电机, 减速器, 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. 此外, 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), 举升高度 (12m-24m), and auxiliary devices (such as grabs, electromagnetic suckers). This flexibility ensures the crane perfectly adapts to various operational scenarios.

Structural Composition of 70 吨双梁桥式起重机

- 1. 主梁: 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, 电线绳, 起重机钩, 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, 减速器, wheels, 和刹车. 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, 和传感器. It is the “brain” of the crane, responsible for controlling the operation of each mechanism, realizing functions such as lifting, 降低, trolley traveling, and crane traveling. 同时, it is integrated with safety protection devices to ensure safe and reliable operation.
- 6. 安全装置: 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), 和防脱轨装置 (to ensure the wheels run stably on the track).
