For electric single beam cranes, their operation cannot be separated from the application of any accessory. Take the sliding wire as an example. Without its current transmission, the equipment would be difficult to operate. Due to the different types of contact wires used in different situations, today we will provide a detailed introduction to the use and classification of contact wires on electric single beam cranes.

Electric single beam crane

1、 Single pole safety sliding wire

The unipolar energy-saving combination sliding line is a widely used bridge crane sliding line in the current market. The conductor material is professional conductive aluminum or copper, among which aluminum sliding contact wire has a high market share. Its products have good conductivity, high cost-effectiveness, safety and reliability. The combination design is convenient for installation and maintenance, with a wide range of applications, and can be applied to various indoor and outdoor environments. The current range is available from 200A-2000A, which can meet the needs of different devices for the product.

2、 Tubular multipole safety sliding wire

The tubular safety sliding wire embeds the conductor in a polyvinyl chloride shell, making installation convenient and simple. It uses purple copper as the sliding wire conductor for bridge cranes, which has good conductivity. However, due to the limitation of the inner groove of the shell, it is mostly suitable for small power mobile devices.

3、 High temperature rigid body contact slip line

The contact sliding wire of a high-temperature rigid body crane is composed of copper conductors and steel structural frameworks or aluminum profiles. It has high mechanical strength and good rigidity, and can withstand strong impact currents. Copper is used as the conductor, which can withstand currents above 3000A. The contact sliding wire of a rigid body bridge crane does not have an outer shell for protection, has a large heat dissipation area, low temperature rise, and long service life. Due to its unique materials, it can be applied in high temperature, high pressure, high humidity, strong corrosion, and dusty environments, such as in industries such as steelmaking, metallurgy, chemical engineering, and docks.
