What is Scraper Winch

Scraper winch, Also known as an electric rake, it is a widely used handling equipment in mining areas. The scraper winch uses a steel wire rope wrapped around a drum to pull the scraper bucket back and forth to transport materials, thereby completing the handling and filling of ores or slag.

Scraper winch is mainly used for raking slopes with a horizontal or inclined angle ≤ 50° and cannot be used as a lifting device. The maximum transportation distance is about 100 meters.

Application Scenarios

Scraper winch has a wide range of applications, mainly used for underground or open-pit ore handling and filling operations in metal mines, coal mines, and other mining sites. Specifically, it can be summarized as follows:

• Metal Ore: In the mining process of metal ore, scraper winch is an indispensable equipment used for ore handling and filling work.
• Coal Mine: The same applies to coal mining, especially on the working face underground, where scraper winch can efficiently rake and transport materials.
• Chemical & Building Material Mines: In addition to metal and coal mines, scraper winch is also widely used in mines in the chemical and building materials industries for mineral handling or filling operations.
• Underground Pit: In the underground tunnels of mines, scraper winch can effectively transport and fill ores, improving mining efficiency.
• Open Pit Site: In open-pit mines, scraper winch can also play its role in carrying out ore handling and sorting work.

Hot Types of Scraper Winches

Classified by Power:

• Electric Scraper Winch: powered by electricity, it drives the drum to rotate through a motor, and then pulls the scraper bucket to move.
• Pneumatic Scraper Winch: powered by compressed air, the drum rotates through a pneumatic drive mechanism.
• Electro-Hydraulic Scraper Winch: Combining electric and hydraulic transmission technology, it has higher transmission efficiency and better control performance.

Types On Basis of Structure:

• Planetary Wheel Scraper Winch: adopts a planetary gear transmission system, compact structure, and smooth transmission.
• Cone Friction Wheel Scraper Winch: transmits power through cone friction wheels, suitable for high torque applications.
• Internal Expansion Friction Wheel Scraper Winch: It transmits power through the frictional force between the internal expansion friction wheel and the drum, and has the characteristics of simple structure and easy maintenance.

Classified by Function:

• Conventional Scraper Winch: mainly used for ore handling and filling work.
• Specialized Scraper Winch: such as explosion-proof scraper winch, suitable for occasions with explosive gases or dust; And towing winches suitable for special working conditions (such as steep slopes).
