Keywords：Gantry bridge crane, 100/20 t
Product Details
The 100/20T double-girder gantry crane is a heavy-duty outdoor lifting device, with a main hook rated capacity of 100 tons and an auxiliary hook of 20 tons. It operates at duty class A5–A6 and is suitable for open-air applications such as plant yards, material storage areas, and component staging yards—locations without overhead building structures. The complete machine comprises box‑type double girders, rigid outriggers, a hoisting trolley, a trolley traveling mechanism, and a comprehensive electrical control system, combining the load‑carrying stability of bridge cranes with the outdoor operational advantages of gantry equipment.
The main hook is designed for lifting heavy steel materials, large equipment, and steel structural components, while the auxiliary hook offers higher speed and is used for handling small parts and turning workpieces. This clear division of labor enhances operational efficiency. The equipment features a three-in-one drive system and disc brakes, and is equipped with multiple safety devices, including overload protection, height limiters, stroke buffers, and wind‑resistant rail clamps, enabling reliable performance even in strong winds. It supports both cab‑mounted and wireless remote‑control operation modes, delivering smooth running and robust load‑carrying capacity.
Compared with indoor operations, this machine requires no dedicated workshop support and is well-suited for ports, heavy‑industry zones, precast component plants, and steel‑structure fabrication facilities, where it handles the transfer, loading, and assembly of large workpieces. Its span, lifting height, and outrigger height are all customizable, offering robust load capacity and versatility across a wide range of operating conditions—making it a core heavy‑duty lifting solution for outdoor material handling.
Special lifting equipment and metal structural components
The company invested 100 million yuan for technological transformation and expansion, with an annual increase of 5,000 tons of metal structural parts, the products cover:
- **Large lifting equipment structural components**: such as bridge lifting components, port machinery support frames, etc. The products are manufactured with high-strength steel to meet the heavy-duty, impact-resistant industrial demand.
- **Architectural steel structures**: including beam and column structures of industrial plants and high-rise buildings, the products are manufactured through standardized production and modular assembly to shorten the construction cycle and reduce the comprehensive cost.
- **Environmentally friendly process**: the production process uses low VOC coatings and is equipped with an exhaust gas treatment system to ensure compliance with the “Comprehensive Emission Standards for Air Pollutants” and the “Standard for Control of Unorganized Emissions of Volatile Organic Compounds”.
