Hengtong Series HT5.1/D

Hengtong Series HT5.1/D is an industrial super large ceiling fan hub structural system designed with a precision mechanical locking and sliding mechanism for stable blade installation and safe operation.

The hub adopts an advanced multi-sliding cavity structure to ensure strong mechanical support and secure blade connection during high-torque operation.

Its design focuses on safety, stability, and long-term durability in large-scale ventilation systems.

Key structural features include:

• Hub circumference composed of four sets of hexagonal steel sliding cavities

• Each sliding cavity contains two precision-matched sliding blocks

• Concave-shaped front surfaces for secure locking engagement

• Blade stem equipped with a protruding lock block for precise fitting

• Central through-hole design allowing fastening bolts to secure all components

• Multi-point locking system ensuring structural stability under load

Key advantages include:

• Strong mechanical locking for enhanced safety

• High structural stability during rotation

• Precise component alignment and anti-loosening design

• Improved durability for long-term industrial use

• Reliable performance in large-diameter ceiling fan systems

It is commonly used in:

• Super large industrial ceiling fans

• Warehouse and logistics ventilation systems

• Industrial factory air circulation systems

• Large public and commercial indoor spaces

• High-ceiling ventilation environments

The HT5.1/D hub system is designed to ensure safe blade fixation, reduce mechanical risk, and support stable high-efficiency airflow in super large fan applications.
