As one of the *key components for power supply in cranes and hoists, how to choose a suitablesliding contactlinecurrent collector is crucial. Here, our company will briefly introduce how to choose a suitable one during the use of sliding contact line current collectors. The sliding contact line current collector mainly consists of components such as the shoe box, shoe piece, spring, collector bracket, and 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. The choice between light-duty and heavy-duty depends on the current of the sliding contact line. Generally, if the current is less than or equal to 500A, a light-duty current collector can be used; if it exceeds 500A, a heavy-duty one should be selected. Secondly, when choosing a sliding contact line current collector, it is essential to consider whether it matches the manufacturer of the contact line. Do not arbitrarily select a current collector, as it 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 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 level of the brush piece on the current collector and replace it periodically. The 1200A high-temperature rigid current collector is composed of components such as the collector shoe, collector brush, stainless steel connecting rod, rotating arm, torsion 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 materials are excellent, and whether the torsion force of the torsion spring and the tension force of the tension spring are designed reasonably. This device collects electrical energy. Therefore, the safe operation of the 1200A high-temperature rigid current collector mainly depends on: 1. The installation of the sliding contact line part; 2. The quality of the collector brush in the current collector; 3. The **contact and contact pressure with the sliding contact line. These three points can be summarized as: three parts selection, seven parts installation and adjustment.
The 1200A high-temperature rigid current collector consists of two parts: the tension device of the mechanical structure and the collector brush that directly slides in contact with the guide rail. It consists of two parts: the tension device of the mechanical structure and the collector brush that directly slides in contact with the guide rail.
