In the field of modern industry and logistics, gantry cranes have become the "backbone" of material handling with their strong carrying capacity and flexible space coverage. Gantry cranes equipped with electric hoists continue to promote industrial upgrading with their intelligent and efficient characteristics.
1.Structural framework of gantry cranes: the cornerstone of stability
The core structure of gantry cranes consists of four modules: gantry, electric hoist, operating mechanism and electrical system:
Gantry: adopts box-type or truss design, consisting of main beam, outrigger and lower crossbeam to form a stable "gantry-shaped" frame. Jinghe crane incorporates high-strength steel and modular splicing technology into the design, which not only guarantees the carrying capacity (up to 200 tons), but also facilitates transportation and quick installation.
Electric hoist: As the core power unit, it integrates lifting motor, travel motor and hook device. Jinghe adopts permanent magnet synchronous motor technology, which saves more than 30% energy compared with traditional motors, and is equipped with a dual braking system to eliminate the risk of hook slipping.
Operating mechanism: including trolley (longitudinally moving along the track) and trolley (laterally moving along the main beam), and cooperate with electric hoist to achieve three-dimensional precise positioning. Jinghe's original variable frequency speed regulation technology can control the operation accuracy within ±5mm.
Intelligent control system: Jinghe crane is equipped with the Internet of Things (IoT) platform, which supports remote monitoring, fault warning and automatic obstacle avoidance functions, and comprehensively reduces the intensity of manual operation.
Working principle: Precision coordination of three-dimensional space handling
The operation process of gantry crane is essentially a perfect linkage of machinery, electricity and control:
Vertical lifting: The hoisting mechanism of the electric hoist drives the hook through a wire rope or chain to lift the heavy object vertically to the target height. Jinghe's patented anti-sway algorithm can suppress the shaking of goods within 1 second and improve loading and unloading efficiency.
Lateral movement: The electric hoist slides horizontally along the main beam track to cover the operating area within the span of the gantry.
Longitudinal movement: The whole machine travels along the ground track through the trolley wheels to expand the operating range. Jinghe cranes are equipped with a laser positioning system as standard, which can automatically align loading and unloading points with an error rate of less than 0.1%.
Collaborative operation: Through the integration of three-axis motion instructions through PLC (programmable logic controller), the continuous action of "lifting-translation-landing" is realized. Jinghe supports customized programming and can adapt to the process requirements of complex scenarios such as automobile manufacturing and wind power installation.
Technological breakthroughs and scenario empowerment of Jinghe gantry cranes
As a benchmark enterprise in the field of domestic gantry cranes, Jinghe solves industry pain points through continuous innovation:
High efficiency and energy saving: Adopting regenerative braking energy recovery technology, the downward potential energy is converted into electrical energy to feed back to the power grid, reducing the overall energy consumption by 40%.
Extreme environment adaptation: For scenes such as high temperature in steel mills and salt spray corrosion in ports, heat-resistant (-20℃~+80℃) and IP67 protection grade products are launched, extending the life by 50%.
Intelligent safety protection: Integrated weight sensor, wind speed monitoring and AI visual recognition system, real-time warning of overload and collision risks, reducing the accident rate by 90%.
As the "air carrier" of modern industry, the technological evolution of electric hoist gantry cranes has always been in sync with the needs of the industry. With "precision manufacturing" as its core concept, Jinghe Crane continues to deepen product innovation and service upgrades, providing customers with full life cycle support from design, installation to operation and maintenance.
