    The internal structure of a low-temperature-resistant hand chain hoist is designed to withstand extremely low temperatures while maintaining smooth and reliable operation. While the specific design may vary among manufacturers, the following are common components and features found in the internal structure of such hoists:

    Chain Mechanism:

    The chain mechanism is a crucial component of the hoist, consisting of load chains and hand chain. In low-temperature-resistant hoists, the materials used in the load chain and hand chain are selected to withstand cold temperatures without becoming brittle or losing flexibility.

    Load Brake System:

    The load brake system is responsible for controlling the descent of the load and preventing it from free-falling. The brake components, such as brake discs and pawls, are designed to function effectively in low-temperature conditions.

    Gear System:

    The gear system includes gears and transmission components that facilitate the lifting and lowering of the load. Materials used in the gear system are chosen for their ability to operate smoothly in cold environments.

    Housing and Enclosures:

    The housing and enclosures of the hoist protect internal components from external elements. These components are designed to provide insulation and prevent the ingress of cold air, moisture, or ice. Materials used in the housing should be resistant to cold-related stresses.

    Bearings and Lubrication:

    Bearings within the hoist are selected for their ability to function in low-temperature conditions. Special low-temperature lubricants may be used to ensure that moving parts remain adequately lubricated and operational.


    Load and suspension hooks are critical components that need to withstand low temperatures without becoming brittle. Hooks may be designed with materials that maintain strength and toughness in cold environments.

    Pawl and Ratchet System:

    The pawl and ratchet system is responsible for securing the load in position and preventing reverse movement. These components are designed to engage and disengage effectively in low-temperature conditions.

    Control Mechanism:

    The control mechanism, including the hand chain and brake lever, is designed for ease of use in cold weather. Hand chains are typically coated or designed to remain flexible at low temperatures.

    Seals and Gaskets:

    Seals and gaskets play a crucial role in preventing the entry of cold air, moisture, or ice into the internal components. They are designed to maintain flexibility and effectiveness in low-temperature conditions.

    Labeling and Certification:

    Low-temperature-resistant hoists are typically labeled and certified for their performance in cold environments. Certifications ensure that the hoist meets industry standards and specifications for low-temperature operation.

    Manufacturers of low-temperature-resistant hand chain hoists may use specialized materials, coatings, and design considerations to ensure the hoist's reliable performance in cold climates. Users should refer to the product documentation, specifications, and certifications provided by the manufacturer to understand the specific features and capabilities of a particular low-temperature-resistant hoist.
