1. It is very important to install screw connectors in various industries. Of course, disassembly and maintenance are equally important. It can easily and quickly complete the task of the screw.
2. Some bolts are installed in very narrow spaces and cannot be tightened and disassembled by extending the arm or hammering.
3. Some devices have been used for a long time in wet places. The bolts are seriously corroded and cannot be disassembled manually, making maintenance difficult.
4. Fastening and dismantling the bolts on the high-altitude pipelines and high-altitude equipment racks, even if the seat belts are fastened, it is difficult for the staff to function. It is difficult for them to do their jobs safely.
5. According to the statistics of the equipment management department, more than 50% of equipment failures are caused by bolt problems, and major equipment accidents caused by bolt problems are also very serious. Therefore, the new equipment installation and maintenance specifications have strict requirements on the bolt tightening torque, which effectively ensures that it is difficult to achieve the required torque value by manual methods.
What are the precautions for using hydraulic wrenches?
1. Select the matching sleeve according to the size of the nut and install it correctly.
2. If the working place is far away from the power supply, when it is necessary to extend the cable, a qualified extension cable should be installed with sufficient capacity. If the extension cable crosses the sidewalk, it should be raised, or measures should be taken to prevent it from being damaged by rolling.
3. When the motor finds abnormal carbon sparks in use, it should stop working immediately, and check and deal with it to eliminate the fault. In addition, the carbon brushes must be kept clean.
4. Confirm that the power supply connected on site is consistent with the nameplate of the hydraulic wrench. Is an earth leakage protector connected?
5. Before powering on, make sure the switch on the electric wrench is turned off. Otherwise, when the plug is inserted into the power outlet, the electric wrench will turn unexpectedly immediately, possibly resulting in a risk of personal injury.
6. Try to find the support point of the reaction force distance as much as possible to prevent the reaction force from hurting people.
7. When working on a ladder or at a high place, measures should be taken to fall from a height, and the ladder should be supported by ground personnel.
