The internal parts structure of a cold-resistant electric chain hoist includes various components that work together to enable the hoist to lift and lower loads in cold environments. While the specific design may vary among manufacturers, the following are common internal parts found in a cold-resistant electric chain hoist:

Electric Motor:

The electric motor is a key component that converts electrical energy into mechanical power to drive the lifting mechanism. In a cold-resistant hoist, the motor is designed to operate effectively in low-temperature conditions.

Gearbox:

The gearbox is responsible for adjusting the speed and torque of the electric motor's output. It ensures that the hoist operates at the desired lifting speed and with sufficient power. In cold-resistant hoists, the gearbox may be designed to handle low-temperature conditions.

Brake System:

The brake system is crucial for stopping the motion of the load when required. It prevents the load from drifting when the hoist is not actively lifting or lowering. Cold-resistant hoists feature brake systems that can function effectively in cold temperatures.

Lifting Chain:

The lifting chain is a load-bearing component that raises and lowers the load. It is typically made of high-strength alloy steel and is guided by the hoist's lifting mechanism. In cold-resistant hoists, the lifting chain is designed to remain flexible and durable in low temperatures.

Load Hooks:

Load hooks are attached to the lifting chain and provide the connection points for securing the load. They are designed to safely support the weight of the load without deformation or failure in cold conditions.

Lifting Mechanism:

The lifting mechanism includes components such as load wheels, chain guides, and sprockets. These components work together to ensure controlled and precise movement of the lifting chain. Cold-resistant hoists have lifting mechanisms designed to operate in low temperatures.

Electrical Components:

The electrical components include wiring, insulation, and control systems. In a cold-resistant hoist, these components are selected or treated to withstand low temperatures and maintain proper electrical functionality.

Seals and Gaskets:

Seals and gaskets are used to protect internal components from moisture and environmental factors. Cold-resistant hoists incorporate seals and gaskets made from materials that remain flexible and effective in cold conditions.

Lubrication System:

The lubrication system ensures that moving parts within the hoist remain properly lubricated for smooth operation. Cold-resistant hoists may use specialized lubricants that maintain fluidity in low temperatures.

Overload Protection:

Overload protection systems are designed to prevent the hoist from lifting loads beyond its rated capacity. Cold-resistant hoists include overload protection mechanisms to enhance safety in cold environments.

It's important to note that the specific design and materials used in the internal parts of a cold-resistant electric chain hoist may vary, and users should refer to the manufacturer's documentation for detailed information on the hoist's construction and operation in cold conditions.
