Its durable structure and heat-resistant features make it essential for high-temperature industrial settings.

Overhead travelling crane with electric hoist

This integrated model combines an overhead travelling crane with a high-performance electric hoist, simplifying load handling. The electric hoist provides smooth and precise lifting/lowering operations, while the crane’s bridge and trolley enable horizontal movement. It’s widely used in various industries for general material handling, offering convenience, hiệu quả, and reliability in both light and medium-duty applications.

Customized overhead travelling crane for warehouse

Tailored to the unique layout and needs of warehouses, this crane can be customized in terms of span, chiều cao nâng, and control system. It optimizes warehouse space utilization, often featuring compact designs to navigate narrow aisles. Equipped with features like automatic positioning or remote control, it enhances efficiency in loading, dỡ hàng, and stacking goods in warehouse logistics operations.

European standard overhead travelling crane

Adhering to strict European safety and quality standards, this crane emphasizes precision, energy efficiency, and low noise. It uses high-quality components and advanced design concepts, ensuring smooth operation and long service life. With compact dimensions and optimized weight distribution, it’s suitable for modern factories and industrial facilities that require high standards of performance and safety.

Low headroom overhead travelling crane for limited space

Specifically designed for spaces with restricted vertical clearance, this crane has a compact trolley and optimized structure to maximize available headroom. It can operate in old workshops, buildings with low ceilings, or areas where vertical space is at a premium. Despite its low profile, it maintains reliable lifting capacity and performance, solving space constraints in various industrial settings.

Overhead Travelling Crane Key Features and Advantages

1. High Lifting Capacity: Overhead travelling cranes can handle loads of various weights, from light tons to hundreds of tons, meeting the needs of different industrial applications.
