LD20T Single-Girder Crane
Keywords：LD20T Single-Girder Crane
Product Details
The LD20T electric single‑girder crane is a commonly used light‑duty lifting device in workshops, with a rated lifting capacity of 20 tonnes. It typically operates at duty classes A3 or A5 and is suited to indoor, ambient‑temperature applications involving standard hoisting tasks. The machine comprises a box‑type main girder, end beams, an electric hoist, a traveling drive, and an electrical control system. Its design is simple and compact, resulting in a lightweight structure that imposes minimal wheel‑load on the building and reduces capital‑construction costs.
The equipment uses an electric hoist suspended beneath the main beam to achieve lifting and lowering, while the trolley moves longitudinally along the plant’s track and the hoist travels laterally, enabling three-dimensional material handling. It can be operated via either a wired handheld controller or a wireless remote control, offering simple and intuitive operation. Standard features include an overload limiter, upper and lower limit switches for the hoist, travel buffers, and power‑off protection, ensuring smooth braking and low operating noise.
Compared with double‑girder cranes, LD single‑girder cranes offer lower capital costs, shorter installation timelines, and simpler post‑installation maintenance, making them well suited for medium‑ and small‑tonnage, low‑frequency lifting operations. They are not intended for use in high‑temperature, flammable/explosive, or highly corrosive and humid environments. Widely employed in settings such as machining, hardware warehousing, mold‑making workshops, and building‑material processing, they facilitate the handling and transfer of steel, workpieces, and equipment. Span and lifting height can be customized to match the dimensions of the facility, making this a cost‑effective, versatile lifting solution for small and medium‑sized plants.
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”.
