Crane Slide Wire Manufacturer
Darui Electric recommends
(1) The power supply crane slide wire series products are innovatively developed and produced by our factory, referencing relevant foreign materials and advanced products, and targeting the accidents prone to occur with exposed slide wires in domestic lifting facilities. This series has three types: composite type, square tube type, and spliced type safety slide wires, which are our factory's products.
(2) The power supply safety slide wire series products developed by our institute are complete in variety and widely used. They can be used for lifting machinery in factories, mines, warehouses, stations, ports, and docks, such as electric hoists, beam and bridge cranes, elevators, automated production lines, and other mobile conductive equipment.
(3) Users can correctly select the appropriate specification of power supply safety slide wire according to the type of lifting machinery, to achieve both meeting the electricity needs of the lifting machinery and saving electricity, energy, and reducing energy consumption and other technical and economic indicators.
(4) Correctly selecting the power supply safety slide wire is the key to obtaining the best technical and economic effects. According to reliability research, using this slide wire can improve the system's reliability by two orders of magnitude. Users should refer to this manual in detail when selecting the power supply slide wire, fully understand the product performance, characteristics, etc., to obtain the best use effect.

2. Product working principle, characteristics, and uses
(1) Main components and their working principles
The power supply safety slide wire device consists of two main components, the conduit and the current collector, and some auxiliary components, as shown in the figure:
1. Conduit: It is a semi-enclosed special-shaped tubular component, which is the main part of the safety slide wire. Inside, 2-9 bare guide rails can be embedded as power supply conductors as needed. The guide rails are insulated from each other and from the shell, ensuring the safety of power supply. It also effectively prevents electric shock accidents for maintenance personnel during live maintenance. Each conduit produced by our factory is 4m in length and can be connected to any required length. Generally, conduits are made straight, but can also be made into arc shapes or other shapes according to special needs.
2. The current collector is a set of brush shells that run inside the conduit. It is driven by a fork (or traction chain, etc.) installed on the electricity-consuming mechanism (such as cranes, trolleys, electric hoists, etc.), making it run synchronously with the electricity-consuming mechanism, transmitting electrical energy through the guide rails and brushes to the motor or other control elements. The number of poles of the current collector brushes ranges from 3 to 16, corresponding to the number of guide rails in the conduit.
(2) Product characteristics of crane slide wire manufacturer
1. Safety: The shell of the power supply safety slide wire is made of engineering plastic with high insulation performance. The protection level of the shell can reach IP13 and IP55 as needed, protecting against rain, snow, frost, and ice attacks as well as contact with foreign objects. The product has undergone various environmental condition tests. The insulation performance is good, and there is no harm to maintenance personnel touching the outside of the power transmission conduit.
2. Reliability: The power transmission guide rail has excellent conductivity, fast heat dissipation, high allowable current density, low impedance, and low line loss. The brushes are made of metal copper and carbon alloy materials with high conductivity and high wear resistance. The current collector moves flexibly, has good directional performance, and effectively controls contact arcs and series arcs.
3. Economy: The power supply safety slide wire device has a simple structure, high allowable current density, low resistivity, low voltage loss, can save about 10% of electricity, realizes replacing steel with plastic and copper with plastic, has a novel design, does not require other insulation structures or compensation wires, and is installed on the same side as the crane control room. It saves installation materials and costs.
4. Convenience: The power supply safety slide wire device integrates multiple pole busbars into one conduit, making assembly simple. Its fixed brackets, connecting clamps, and suspension devices are supplied as universal parts. Installation, disassembly, adjustment, and maintenance are also very convenient.
(3) Uses: The power supply safety slide wire device can be used for electric hoists, electric beam and bridge cranes, stackers, automatic testing lines for electromechanical products, automated production lines, mobile electric tools and other mobile conductive equipment, as well as fixed busway installation in factories, mines, workshops, and office areas.
