Single-girder low headroom hoists (commonly referring to low headroom electric hoists or low headroom wire rope electric hoists) are lifting equipment specially designed for factories with limited building height. Their core function lies in breaking through spatial limitations, enhancing operational efficiency and safety, which is specifically reflected in the following aspects:

1. Solve the lifting problem in low-rise factories

Compact structural design: Through technologies such as C-shaped structure, hollow support shaft for cable concealment, and modular counterweight box, the equipment height is compressed by 200-500mm, maximizing the working range of the hook. For instance, the "C" size of the STK ultra-low headroom chain hoist is 60% smaller than that of the standard hoist. With a lifting capacity of 5 tons, the distance from the bottom of the crossbeam to the hook is only 210mm, completely solving the hoisting bottleneck in low-rise factories.

Improved space utilization: Suitable for factories with a floor height of less than 6 meters, it can be installed without expansion or renovation, directly reducing the construction cost of the factory.

2. Efficient material handling and precise operation

Multi-speed lifting and frequency conversion control: Supports single, dual-speed or frequency conversion stepless speed regulation, achieving millimeter-level positioning and meeting the requirements of precision assembly. For instance, the single-girder low headroom wire rope hoist is equipped with a 4-pole lifting limit switch, which can switch between fast and slow speeds to prevent the goods from swinging.

High load capacity: Covering a lifting capacity of 0.5 to 20 tons, suitable for scenarios such as mechanical manufacturing and warehousing logistics. For instance, the SHA7 hoist from Zhejiang Shuangniao successfully completed the hoisting of heavy components in a tunnel project in the UK.

360° rope ejection and quick modification: The square outer cover supports multi-directional rope ejection and can be quickly converted into a fixed type or a suspended trolley running type, flexibly meeting the needs of different workstations.。

3. Strengthen security guarantees

Multiple protection mechanisms

Overload protection: Automatically cut off power supply to prevent accidents caused by overloading.

Limit device: Prevents lifting or overtravel during operation.

Anti-sway technology: By means of synchronous operation of double chains (such as STK chain hoists) or electronic anti-sway systems, the load stability is ensured.

High protection grade: The motor adopts IP54 protection, and the electrical system integrates Schneider components, making it suitable for harsh environments such as humidity and dust.

4. Reduce operating costs

Energy-saving design: Variable frequency drive technology reduces energy consumption, and the braking energy feedback system further lowers electricity bills.

Easy maintenance: The modular design enables quick replacement of components. The counterweight box can be filled with scrap steel or stone materials, saving steel costs. For instance, the counterweight box design of low headroom hoists reduces the external dimensions compared to traditional counterweight blocks, thereby lowering the difficulty of maintenance.

Long-life materials: The hoisting reducer adopts alloy steel three-stage reduction, which operates smoothly and has a long service life, reducing the downtime for maintenance.

5. Adapt to diverse scenarios

Mechanical processing: used for equipment installation and hoisting of heavy components.

Warehousing and logistics: Achieve rapid stacking and sorting of goods.

Construction engineering: Hoisting prefabricated components, cement pipes, etc.

Special environments: We offer customized solutions such as explosion-proof and clean types to meet the demands of industries like chemical engineering and food processing.

6. Promote intelligent upgrading

Internet of Things integration: Supports remote monitoring and fault early warning to achieve predictive maintenance.

Collaborative operation: It can be linked with AGVs and robots to build an intelligent logistics system. For instance, in the automotive manufacturing painting production line, low headroom hoists work in conjunction with automated equipment to enhance the production pace.

Typical application cases

In the automotive manufacturing: Body painting production line, low headroom hoists achieve precise hoisting in confined Spaces.

Aerospace: Aircraft fuselage assembly station, high-altitude operations are completed through low headroom design.

In the scenarios of material handling and sorting in warehousing and logistics, low headroom hoists combined with automated systems can increase efficiency by more than 30%.
