Container gantry crane technical specifications
Container gantry crane technical specifications
I. Overview
The core purpose of this technical specification is to comprehensively and meticulously detail the technical parameters, design requirements, and performance standards of the custom container gantry crane. As a critical piece of equipment in container handling operations, the performance of this crane directly impacts the efficiency, safety, and stability of the entire operation process.
To meet the demands of high efficiency, safety, and stability, we have implemented stringent controls in the design of the container gantry crane. From a technical parameter perspective, we have defined key indicators such as lifting capacity, working range, and operating speed to ensure optimal performance across various operational environments.
In terms of design requirements, we emphasize the structural strength, stability, and durability of the crane. Through advanced computational methods and simulation testing, we have optimized and improved each component of the crane. Additionally, we have prioritized the safety and comfort of operators by designing user-friendly interfaces and protective measures.
Regarding performance standards, we strictly adhere to international standards and industry regulations in our design and testing processes to ensure the crane maintains excellent stability and reliability under various working conditions. Furthermore, we pay special attention to the crane's energy efficiency, aiming to reduce energy consumption and emissions, thereby achieving green and environmentally friendly handling operations.
II. Environmental Parameters
Working Environment: Outdoor, suitable for railway freight yards or port terminals.
Climate Conditions: Suitable for normal temperature and humidity environments, capable of withstanding certain levels of wind, rain, and sun exposure.
Ground Conditions: Tracks are laid flat, with a solid foundation that meets the operational requirements of the crane.
III. Equipment Performance Parameters
Model: Custom container gantry crane.
Rated Load Capacity: 45 tons (under the spreader, including the container and spreader mass).
Lifting Height: Determined by the number of stacked container layers, with a maximum reach of 20 meters.
Span: 35 meters (distance between the centerlines of the traveling wheels on both sides under the crane's two-leg support).
base Distance: Determined according to design requirements to ensure crane stability.
Productivity: Not less than 30 containers per hour (under standard operating conditions).
Power Supply: Cable-type, with power supplied to the equipment via cables and cable reels to ensure stability and reliability.
IV. Main Structure and Technical Features
Gantry frame: The gantry frame features a specially designed U-shaped leg structure, which not only enhances overall robustness but also significantly improves equipment stability. The U-shaped legs distribute weight evenly, ensuring the equipment remains steady even under heavy loads, providing a safe and reliable working environment.
Trolley Travel Mechanism: The trolley travel mechanism employs a rail-based travel system, ensuring smooth movement along designated tracks. Advanced buffers and limit switches are also included to ensure safety and stability. The buffers effectively absorb impact forces during operation, preventing damage from collisions, while the limit switches precisely control the movement range, preventing the equipment from exceeding safe boundaries.
Hoist Trolley Assembly: The hoist trolley assembly is a critical component, featuring an upper slewing mechanism that allows the trolley to rotate flexibly in various directions. This design greatly enhances the equipment's adaptability, enabling it to meet the demands of different operational scenarios, whether in confined spaces or complex conditions.
Spreader: To accommodate containers of different sizes, the equipment is equipped with an electric telescopic spreader. This spreader can adjust its length as needed, easily handling 20-foot, 40-foot, and 45-foot international standard containers. The electric telescopic design not only improves operational efficiency but also ensures lifting accuracy and safety.
Electrical System: The electrical system, serving as the "brain" of the equipment, utilizes an advanced variable frequency speed control system, ensuring smooth and energy-efficient operation. Additionally, a PLC controller is included for automated control, allowing users to execute complex operational commands through a simple interface, significantly enhancing work efficiency and convenience.
Safety Protection Devices: To ensure safe operation, the gantry crane is equipped with comprehensive safety protection devices. The hoisting mechanism interlock prevents hook drops due to misoperation; the trolley travel mechanism safety device monitors the trolley's operational status in real-time, ensuring safe movement within designated limits; the trolley travel mechanism safety device prevents the trolley from tipping over due to exceeding track limits. Furthermore, an emergency stop button provides an additional layer of safety, allowing immediate equipment shutdown in emergencies to ensure the safety of personnel and cargo.
V. Materials and Manufacturing Processes
Main Steel Plate Thickness: Determined according to specific design requirements and project needs to ensure the overall structure has sufficient strength and stability. Appropriate steel plate thickness not only supports the structure's weight but also maintains structural integrity and safety under various external pressures and challenges.
Main Component Materials: We use high-quality alloy steel that has undergone rigorous screening. This material inherently possesses excellent mechanical properties and fatigue resistance. After professional heat treatment, its wear resistance and corrosion resistance are further enhanced, ensuring stable operation in harsh environments.
Welding: We employ industry-leading high-quality welding processes, ensuring each weld is robust and reliable through precise operations and strict monitoring. This not only enhances the overall structure's strength and stability but also eliminates potential safety hazards due to weld issues.
Surface Treatment and Coating: To ensure long-term stable operation, we perform rigorous sandblasting and rust removal on steel plate surfaces to eliminate corrosion and contaminants. High-performance anti-corrosion coatings are then applied, providing a solid protective barrier that significantly extends the equipment's service life.
