First, since the crane maintenance is a special vehicle, the operator should receive training and guidance, have a full understanding of the structure and performance of the machine, and obtain certain operational and maintenance experience before operating the machine. The product maintenance and repair instructions provided by the manufacturer are the necessary information for the operator to operate the equipment. Before operating the machine, be sure to read the maintenance instructions and operate and maintain according to the requirements of the manual.
The second point, pay attention to the workload of the crane maintenance and running-in period, the working load during the running-in period should generally not exceed 80% of the rated working load, and should arrange the appropriate workload to prevent the overheating caused by the continuous operation of the machine for a long time. occur.
Third, pay attention to the maintenance and repair of the crane. Observe the indications of each instrument. If an abnormality occurs, stop it in time to eliminate it. If the cause is not found, the operation should be stopped before the fault is eliminated.
Fourth, pay attention to crane maintenance and often check the lubricating oil, hydraulic oil, coolant, brake fluid and fuel oil (water) position and quality, and pay attention to check the sealing of the machine. During the inspection, it was found that the oil and water were too much, and the reason should be analyzed. At the same time, the lubrication of each lubrication point should be strengthened. It is recommended that the lubrication point be filled with grease for each shift during the running-in period (except for special requirements).
Heavy steel grating refers to the special requirements for the carrying capacity of steel gratings. It is generally used in ports, offshore platforms, military factories and other areas, and the carrying capacity is generally more than 40 tons. The width of the flat steel of the heavy steel grid plate is generally 60-180mm, the thickness of the flat steel is generally 6-10mm, the diameter of the twist steel is generally 8mm or 10mm, and the spacing of the flat steel is generally 30-40mm.
Heavy load grid board classification:
There are two types of heavy load grid plates: pressure welding and pressure locking:
Heavy-loaded pressure-welded steel gratings are made by pressure-welding technology to form a permanent connection between the high-strength heavy-duty square steel and large-size load-bearing flat steel through high temperature and high pressure, so as to form a better lateral (Steel Grating width direction) carrying capacity. It is generally recommended that both sides of the steel grating be edged with edged plates.
The heavy-loaded grid plates can provide better lateral load-carrying capacity, and can effectively prevent the tilt instability of the load-bearing flat steel, and are used more as heavy-duty steel gratings.
Due to the special nature of heavy-duty grid panels, we generally advise our customers to inform them of the load requirements and support conditions. We select the most economically reasonable specifications for our customers.
