Detailed Introduction
The hoisting mechanism is an important driving device of the crane. The QJ series hoisting mechanism is designed and manufactured based on forty years of R&D and manufacturing experience, and with reference to similar foreign products in recent years. The technical parameters and installation dimensions of this series of hoisting mechanisms are the same as those of similar foreign products, making it easy for users to select and replace similar foreign products.
The QJ series hoisting mechanism is suitable for various types of engineering machinery, such as automobile and crawler cranes, railway cranes, ship decks, wharf and container cranes. Due to its compact structure, it can be directly installed inside the drum to save space.
The QJ series hoisting mechanism is used in large quantities in well-known domestic and foreign engineering machinery products, and users evaluate its quality level as equivalent to similar foreign products.
The technical parameters and installation dimensions of the hoisting mechanism are basic. If you need to select, you need to communicate with technical personnel from both sides to sign a technical agreement to determine the technical parameters and installation dimensions.
We have years of design and practice experience to meet the special requirements of users. In recent years, the empty hook quick release hoisting mechanism developed by our company has been used in impact compactors, with reliable quality and high user satisfaction.
Structural Features
1. The planetary reducer is placed inside the drum for a more compact structure.
2. The hoisting mechanism is equipped with a multi-disc brake.
3. Low noise operation.
4. High efficiency.
5. Long service life, convenient oil injection and drainage.
Operating Conditions
The operating temperature range of the hoisting mechanism is -20℃ to +40℃.
Environmental influences such as salt water, salt air, sand, dust, overpressure, heavy vibration, severe impact, ambient temperature, ingress of media, and similar issues will hinder product functionality.
