The overhead crane is easy to power off during use, and sometimes sparks are generated in the transmission pipe. In severe cases, there is the sound of firecrackers on the sliding contact line, which causes the current collector to be replaced too frequently, which affects production. For this reason, the following improvements have been made to the overhead crane:
1. Increase the chamfer of the collector brush and polish it smoothly;
2. Increase the spring strength and elasticity between the two opposite brushes of the current collector to ensure that the spring recovers freely;
3. Deepen. Reinforce the spring seat in the current collector to ensure that the recovery spring of the brush is not easy to "cross position" during work;
4. The overhead crane manufacturer tells you that the connecting block at the connection of the two sections of safety trolley wires must be chamfered to ensure a smooth transition of the collector. At the same time, in order to ensure the normal use of the safe trolley wire, the standard operation of the operator, the regular maintenance and inspection of the maintenance worker are also indispensable.
Due to the influence of vibration, wear, pressure, temperature and other factors on overhead crane trolley reducer, oil leakage often occurs in the static sealing parts of each joint surface. The traditional treatment method involves disassembling the reducer, replacing the sealing gasket or applying sealant, but it is time-consuming and laborious, and it is difficult to ensure the sealing effect, and leakage will occur again during operation. The manufacturer of overhead crane tells you that in contemporary western countries, polymer composite materials are often used for on-site leakage control, and the most widely used Blessing Shilan series. The manufacturer of overhead crane tells you that polymer materials can be repaired without disassembly, and the material has superior adhesion, oil resistance and 350% stretch, which can well overcome the impact of reducer vibration, and the repair effect is better than traditional methods. efficient.
