Characteristics of Truck Crane Running - in Period

2017-01-19 08:51:33
Truck crane take-in period refers to the new car or overhaul after the early run stage, usually 1000-1500 km. What are the characteristics of the truck hanging go together?
Truck crane take-off period is characterized by:
(1) fasteners easy to loose.
(2) wear parts faster. Although the crane factory before running in accordance with the provisions of the running-in process, but the mechanical surface is still rough, coupled with the new parts more metal particles fall off, so that wear and tear increased.
(3) lubricating oil perishable. As the mechanical fit within the gap with the smaller, poor film quality, temperature rise, the oil easily oxidized deterioration. Coupled with more metal particles mixed with oil, so that the oil quality.
(4) fuel consumption. In order to ensure the run-in period of small-load operation, the carburetor installed a speed limiter, resulting in thicker mixture. At the same time, the friction between the larger parts of the friction also increases fuel consumption.
(5) more failures. As the mechanical processing, assembly, there are deviations, but also contains some difficult to find hidden dangers, in the process of moving is likely to stuck, fever and leakage and other failures.
Slow start, slow fuel, timely shift, slow braking, and strictly control the water temperature, often check the transmission, the use of high-speed, low-speed oil, Drive axle and hub temperature.
Truck crane during the abnormal move should be handled properly, not self-assertion. Truck crane to a certain mileage, it should be maintenance and routine maintenance. Change of lubricating oil at the expiration of the period of separation, removal of speed limit, comprehensive adjustment, fastening, the vehicle to the normal state of technology.
