When the 30KW electric rake winch for coal mines is used to rake the mine underground, the temporary fixing method is generally adopted, and there is no permanent fixed foundation. The fixing must be firm, and the fixing pile of the machine must be checked frequently for signs of loosening. Any problems should be dealt with in time to ensure the safe operation of the equipment.

Overview Cable check and cable, cable lookups are a bit a bit of arbitrary wiring no need to publicly line. It can greatly improve the construction progress, which is a new test tool in on site construction such as electricity, telecommunications, automation control. The cable calibration equipment is based on the characteristics of foreign new types of wire tools, combined with the actual situation of China, using digital identification technology, making the test work simple and accurate. Technical parameter Parameter Display the maximum row of LEDs 1000, the maximum distance of the quilt is 40km 1.5mmmmmmmmma size Transmitter Size 135 70 24MM Receiver Size 135 70 24mm Function The entire instrument consists of a transmitter and a receiver; There is no need to determine the public line to make it easy to use Wire recognition, distribution, application to a part of the wire or multi-heeled wire One item can be identified, if you need to distinguish more wires can measure or use multiple instruments Can determine whether there is a short circuit or disconnect between the wires The receiver is also a disconnect detector that can be used to measure whether the wire is turned on The structure is small and easy to operate.
