I believe you are referring to the product characteristics of "pneumatic hoists," though the term "running pneumatic gourd" is not a standard or commonly used description in the industry. Pneumatic hoists, particularly those of high quality like the KA1 and KA3 models from KHC, offer a range of features and benefits. Below are some key product characteristics of pneumatic hoists:

Load Capacity:

KA1 model: Load capacity ranges from 250kg to 1000kg.

KA3 model: Load capacity ranges from 3000kg to 30000kg.

Operational Control:

KA1 model: Operated through control of the air circuit, with upper and lower limit switches for precise control.

KA3 model: Offers two-way (KA3S) or four-way (KA3M, including up, down, left, right) control buttons for enhanced maneuverability.

Durability and Safety:

Both models feature rugged construction and are designed for long-term use.

Equipped with overload protection and air cut-off protection devices to ensure safe operation.

Explosion-Proof Design:

The KA1 model is designed to eliminate sparks, electric shocks, and leaks, addressing explosion-proof requirements.

Speed and Adjustability:

Pneumatic hoists offer high-speed operation, adjustable to meet different lifting needs.

The KA1 model can operate quickly and its speed can be infinitely adjusted, up to 3 times that of electric hoists and 5-10 times that of manual hoists.

Environmental Friendliness:

Pneumatic hoists use compressed air as a power source, making them energy-efficient and environmentally friendly.

Both models produce low noise levels and are suitable for use in environments requiring quiet operation.

Ease of Maintenance and Use:

Pneumatic hoists have a simple structure, making them easy to maintain.

Operators can be trained quickly to use these hoists effectively.

Additional Features:

The KA3 model uses a chain as the lifting medium, which is more durable than wire rope and offers a longer service life.

Both models can be equipped with accessories such as control handles, chain bags, and hooks to enhance functionality.
