The GTH125 Gaston I-beam walking pneumatic hoist is a high-performance, high-reliability pneumatic handling equipment specially designed for the industrial and construction fields. With its unique I-beam walking design, this pneumatic hoist can easily achieve stable and smooth walking on various I-beam tracks, greatly improving work efficiency and safety.
Product features are as follows:
Efficient handling: GTH125 pneumatic hoist adopts advanced pneumatic technology to provide strong lifting force and stable walking speed, and can quickly and accurately complete various heavy object handling tasks.
Stable and reliable: The I-beam walking design ensures the stability of the hoist on the track and can maintain smooth operation even in complex or uneven working environments, reducing safety hazards caused by equipment shaking.
Easy to operate: Equipped with an intuitive and easy-to-use control system, operators can easily grasp the operating status of the equipment and achieve precise control. At the same time, the equipment also has an overload protection function to ensure that it automatically stops running when the load range is exceeded to prevent accidents.

| The figure shows typical pneumatic motor torque and power curves under two different air pressures. The speed torque and power of the motor decrease as the air pressure decreases. | The figure shows the torque and speed curves of the motor under two different air pressures. The speed and torque of the motor decrease as the air pressure decreases. The torque decreases significantly, while the motor speed decreases slightly as the pressure decreases. |
