Whether the crane runs well or not, the air conditioning effect is very important. Today, let`s talk about the use and maintenance of air conditioners. How to operate the air conditioning system First start the engine, turn the wind speed to turn on the air conditioner, press the cooling switch to start the refrigeration function; turn the temperature adjustment knob to adjust the temperature, press the inner and outer circulation button to start the fresh air function, glass defrost, lower air outlet and upper air outlet are opened according to demand Or adjust the angle. When turning off the air conditioner, turn off the refrigeration switch first, and then adjust the wind speed knob to gear 0. What to do for air conditioning maintenance Daily maintenance of the air conditioner mainly focuses on cleaning the dust on the air inlet filter and the surface of the condenser. Open the trunk cover in the control room, remove the filter element bolt on the evaporator box, remove the fresh air converter plug, take out the filter element for blowing or replace the filter element; remove the protective net on the condenser to remove the oil on the condenser. What to do if the cooling effect of air conditioning is not good First of all, make sure that the air inlet behind the seat cannot be covered by objects; otherwise, the cooling effect will be greatly reduced. Check the air conditioner insurance in the fuse box, and replace it in time if it is damaged. Observe whether the refrigerant is sufficient through the sight glass on the dryer. If it is missing, please add it in time. Measure the pressure switch on the dryer, and it should be in a connected state after starting the air conditioner. After starting the air conditioner, observe whether the compressor is running, and if it does not work properly, perform maintenance in time. Have you gotten the tips for using and maintaining the air conditioner of the crawler crane?

Periodic Inspection And Management Of Crawler Crane Lifting machinery users must frequently inspect and maintain the lifting machinery in use, and formulate a regular inspection management system, including daily inspection, weekly inspection, monthly inspection, and annual inspection, and dynamic monitoring of cranes. Any abnormal situation Discovery and deal with it in time to ensure the safe operation of hoisting machinery. (1) Daily inspection. The routine maintenance items in charge of the operation by the driver mainly include cleaning and sanitation, lubrication of transmission parts, adjustment and fastening work. Test the sensitivity and reliability of the safety device by running, and monitor for abnormal sounds during operation. (2) Weekly inspection. It is carried out by the maintenance worker and the driver together. In addition to the daily inspection items, the main content is visual inspection, checking the safety status of hooks, retrieval devices, wire ropes, etc., the sensitivity and reliability of brakes, clutches, and emergency alarm devices. Observe whether there are abnormal noises and overheating of the transmission parts. (3) Monthly inspection. The inspection is organized by the equipment safety management department and carried out jointly with the relevant personnel of the user department. In addition to the weekly inspection, it mainly conducts state inspections on the power system, lifting mechanism, slewing mechanism, operating mechanism, and hydraulic system of the hoisting machinery. For deformed, cracked, and corroded parts and components, check the reliability of the power feeding device, controller, overload protection, and safety protection device for the electrical control system. Check the fault signs caused by the leakage, pressure, temperature, vibration, noise and other reasons of the lifting machinery through test operation. After observation, subjective inspection of the crane's structure, support, and transmission parts is carried out to understand and master the technical status of the whole crane, and to check and determine the source of abnormal phenomena. (4) Annual inspection. The unit leader organizes the equipment safety management department to take the lead, and conducts jointly with relevant departments. In addition to the monthly inspection items, it mainly conducts the technical parameter test and reliability test of the hoisting machinery, through the testing equipment, the hoisting machinery, the moving parts of the working mechanism The technical condition of the lifting equipment is evaluated through the test of safety devices and components. Arrange for overhaul, renovation, and renewal plans. To learn more, you can also pay attention to storage and lifting

Precautions for the Safe Use of Cranes 1. Crane operation must pass the training examination and hold a special equipment operation certificate before it can be operated; 2. Before driving, check the mechanical equipment carefully, inject oil strictly in accordance with the lubrication regulations, and keep the amount of oil appropriate; 3. Check whether the electrical parts and protective safety devices are intact and reliable. 4. If the main accessories such as the controller, brake, limiter, electric bell, emergency switch, etc. fail, it is strictly forbidden to lift it; 5. The driver must strictly abide by the company and workshop management systems. The operation can be performed after confirming the command signal, and the bell should be sounded before driving. However, anyone who issues an emergency stop signal should stop; 6. When the hook is placed in the lowest position, there should be at least two turns of the wire rope on the drum. Wire rope wear and corrosion exceeding 40% of the surface wire diameter, deflection around the ring, breaking a strand or breaking wire in a lay length exceeding 5% of the straight-winding wire and 10% of the inter-winding wire shall be prohibited. 7. At the beginning of the lifting operation, the first hook should be tested first. When the heavy object is lifted 200mm away, do a brake test to confirm that the large and small trucks are running normally and the lifting mechanism is working properly and the brakes are reliable before it can be put into production. 8. During load operation, the distance between heavy objects and obstacles on the running line shall be at least 0.5 meters. When no load, the hook shall be 2.5 meters above the ground. When approaching the winch stopper, large and small vehicles approaching the terminal or encountering adjacent traffic, the speed should be slow. It is not allowed to use reversing instead of braking, stop switches instead of stop switches, and emergency switches instead of ordinary switches. 9. You should walk and go up and down on the specified safe walkways, special platforms or escalators. The two sides of the cart track are not allowed to walk except for maintenance. Walking on the trolley track is strictly prohibited. It is not allowed to cross from one crane to another. 10. Operation after drinking is prohibited. Open-air gantry cranes should stop working when there is a storm, lightning strike, or strong winds above level 6, cut off the power supply, plug the front and back of the wheels to securely fix the hooks and wheels.
