Winter maintenance is crucial for excavators as the cold temperatures and harsh weather conditions can have a negative impact on the machine. This article will provide some key winter maintenance measures to ensure that excavators operate efficiently during the cold season. Fluid Protection: In winter, condensation of fluids can damage critical components of the excavator. It is important to ensure that the engine coolant and hydraulic oil maintain the appropriate temperature and viscosity. Use antifreeze to protect the coolant and ensure that the hydraulic oil has the proper viscosity to ensure the normal functioning of the machine. Battery Maintenance: Low temperatures can adversely affect battery performance. Regularly check the battery's charge level and electrolyte levels, and ensure that the battery connections are secure. If possible, use a heater to maintain the battery at an optimal temperature. Fuel Management: In winter, fuel can freeze, affecting the fuel supply of the excavator. Use fuel additives with anti-freeze properties to prevent fuel from freezing, and ensure that the fuel filter is functioning properly. Additionally, regularly drain off waste oil and water to ensure the proper operation of the fuel system. Tire and Track Maintenance: Low temperatures and snow in winter can have a negative impact on the tires and tracks of the excavator. Inspect and adjust tire pressure to the manufacturer's recommendations, and consider using winter-specific tires if necessary. For excavators with tracks, ensure that the tracks are free from ice and snow buildup and check for any signs of wear or damage. The operator's comfort and safety are essential during winter operations. Ensure that the cabin is properly insulated and equipped with heating to keep the operator warm. Pay attention to visibility by clearing snow and ice from the windows and mirrors. Also, check the effectiveness of the defrosting system.

Agricultural excavator walking without strength is the most common fault in the walking process, sometimes it is a unilateral fault sometimes both sides of the walking are faulty, resulting in this fault is generally due to the following reasons: 1, the central rotary joint internal leakage, oil leakage. Agricultural excavator central rotary joint is the upper body hydraulic circuit connecting the important hub of the chassis, when the central rotary joint sealing effect is poor will produce internal leakage or oil leakage phenomenon, drive the hydraulic motor of the hydraulic oil can not fully reach the hydraulic motor, part of the hydraulic oil through other circuits to return to the tank, resulting in a loss of pressure in the hydraulic circuit, resulting in hydraulic motors are not strong. 2、Walking motor internal leakage, failure. Walking system by walking balance valve, walking safety valve, walking speed switching valve, walking speed switching cylinder, walking brake cylinder, throttle valve and walking motor composition, when a valve group produce internal leakage will cause the walking system hydraulic circuit pressure loss, resulting in walking no power. 3, hydraulic pump pressure is insufficient, pump control circuit failure. Hydraulic pump pressure is also an important cause of walking without power, leading to hydraulic pump pressure is mainly due to pump leakage, pump control system failure, resulting in pressure loss. 4, the main control valve internal leakage. The main control valve is a multi-spool valve group, when the working time is long or when the hydraulic oil contains impurities will lead to wear and tear of the spool, when the control of the hydraulic circuit of the walking system spool wear and tear is too large, there will be an internal leakage, resulting in a loss of pressure in the hydraulic circuit, resulting in the walking of the lack of strength. 5, the pilot system secondary pressure oil pressure is insufficient. Pilot system secondary pressure oil is output by the proportional control valve, when the agricultural excavator cab walking valve leakage, jamming will lead to the pilot secondary pressure oil pressure is insufficient to push the main control valve spool in place, resulting in a reduction in the walking system hydraulic circuit flow. The above points are the main reasons for the agricultural excavator walking without strength, understand these, when encountering similar failures in the future, the constructor can be resolved by himself.

Jining City 2023 first half of the green low-carbon high-quality development and investment in key projects on-site observation will be held from July 31 to August 2, a total of 48 observation projects, with a total investment of 53.319 billion yuan, each county and municipal area (functional area) to observe 3-5 projects, are more than 100 million yuan of the "top ten" industrial projects, with strong In the afternoon of 31 July, the delegation walked into the Jining City Economic Development Zone Hightop Factory with an annual output of 5,000 units of intelligent equipment manufacturing project. The project is a key investment project in Jining Economic Development Zone, invested 620 million yuan by Shandong Hightop Group, a high-growth foreign trade enterprise. The company attaches great importance to product research and development and scientific and technological innovation, and owns more than 40 utility model patents and invention patents for mini excavators, sprayers, lawnmowers, skid steers, and crawler trucks, etc. The products are all sold to Germany, Italy, Italy, and the United States, and the products are all sold to Germany, Italy, and the United States. All products are sold to Germany, Italy, the United States, Canada and other 40 countries and overseas regions. The project makes use of the existing workshop of 30,000 square metres, and puts on 8 new production lines of intelligent excavators, purchases more than 40 sets of bending machines, drilling machines, CNC machine tools, welding robots, laser undercutting machines, etc., with an annual production capacity of 15,000 sets of intelligent unmanned excavators, intelligent lawn mowers and polyurethane foam sprayers. In March, April, May and June this year for four consecutive months of micro and small excavator production of the country's first, the export volume of the country's first. After the completion of the project, it can achieve export earnings of 50 million US dollars per year and create more than 200 new jobs. Source: Qilu.com

Wheeled excavators are excavators that can be driven on the ground, and they typically use a hydraulic system to control the movement of the arm and bucket. Wheeled excavators are generally better suited to working on flatter ground than crawler excavators because they can move faster, which increases productivity. wheeled excavator  Most foreign wheel excavators travel at a speed of 25-40km/h The wheel excavator is a construction type wheel and tire walking excavator with fast walking speed, long-distance self-transition and quick replacement of various operating devices. The advantages of mobility, flexibility and efficiency have won over customers. At present, the driving speed of foreign wheel excavation is mostly 25-40km/h, and most of the domestic excavation speed is 20-35km/h, and some can even reach 54km/h. It can be said that although wheel excavators do not occupy a mainstream position in China, their technical level is not behind. However, it is important to note that a wheeled excavator is not a vehicle specifically designed to travel, but rather a tool for digging and moving earthmoving materials. Therefore, when using a wheeled excavator, extra care is required to avoid collision or damage to other facilities or personnel during driving. In summary, the top speed of a wheeled excavator depends on many factors, including the size and power of the machine, ground conditions, and the skill level of the operator. If you have specific questions about a particular machine or excavation project, it is recommended that you consult a professional contractor or equipment dealer for more detailed information.
