As one of the most critical components for power supply in cranes and hoists, the high-temperature 1200A rigid current collector is essential. How to choose a suitable one for yourself is crucial. Here, our company will briefly introduce how to select a suitable sliding contact line current collector during use. The sliding contact line current collector mainly consists of components such as the shoe box, shoe piece, spring, current collector bracket, and current collector support part. First, we can select the current collector based on the current of the sliding contact line. Current collectors are divided into heavy-duty and light-duty types. Whether to choose a light-duty or heavy-duty current collector is determined by the current of the sliding contact line. Generally, if the sliding contact line current is less than or equal to 500A, a light-duty current collector can be selected; if it is greater than 500A, a heavy-duty current collector should be used. Secondly, when selecting a sliding contact line current collector, it is important to consider whether it matches the manufacturer of the contact line. Do not arbitrarily choose a current collector, as this may affect the normal use of cranes and hoists, and may also cause greater damage to the sliding contact line. The brush piece on the current collector is made of copper-containing carbon-based pressed material. After purchase, check whether it matches the model of the sliding contact line. Since the current collector itself is a consumable item, long-term use will wear the brush piece, so it is necessary to regularly check the wear degree of the brush piece on the current collector and replace it periodically. The high-temperature 1200A rigid current collector is composed of components such as the collecting shoe, collecting brush, stainless steel connecting rod, rotating arm, coil spring, tension spring, limit plate, and support shaft. The quality of its sliding contact with the sliding contact line mainly depends on whether the structure of the current collector is reasonable, whether the material is excellent, and whether the design of the coil spring torque and tension spring force is reasonable. This device collects electrical energy. Therefore, the safe operation of the high-temperature 1200A rigid current collector mainly depends on: 1. The installation of the sliding contact line part; 2. The quality of the collecting brush in the current collector; 3. The good contact and contact pressure with the sliding contact line. In summary, these three points can be summarized as: three parts depend on material selection, and seven parts on installation and adjustment.
The high-temperature 1200A rigid current collector consists of two parts: the tension device of the mechanical structure and the collecting brush that directly slides in contact with the guide rail.
