The suspended door primarily operates on the lever balance principle. A trackless suspended door has a fulcrum and then balances the weights at both ends. The door is supported by two guide roller sets beneath the door leaf, lifting it off the ground.龙门架 ensures the door leaf remains upright, thus enabling the opening and closing function. When closing, as the door leaf moves forward, the roller sets provide upward support, pulling the door leaf downward.


The components of a suspended door include:

Primary Controller

It serves as the command center for the trackless suspended door, issuing commands through a broad integrated module programmed with instructions to control motor or electromechanical locking systems; simultaneously, the main controller adjusts parameters such as door opening speed and range.

2. Trackless Suspended Door Infrared Proximity Sensor

Serve as a collector of external signals, akin to human eyes, and upon detection of a moving object within its operational range, it sends a pulse signal to the main controller.

Three, Trackless Suspended Door Power Motor

Provide the active power for opening and closing doors, controlling the door's acceleration and deceleration operation.

Four: Trackless Floating Door Traveling Track

Just as train tracks guide the wheels, the hoist equipment's wheel system confines the door body to move in a specific direction.

Five. Trackless Floating Door Body Hoisting Wheel System

Used for hanging sliding door bodies, while simultaneously driving the door bodies to operate under power traction.
