Workshop heavy-duty trolleys and railcar climbing capabilities
In general, the maximum climbing capacity of the so-called workshop factory heavy-duty truck refers to the slope that the transfer vehicle can climb when overcoming the wheel rolling resistance and air resistance on a good road surface. The maximum climbing degree of the trackless transfer vehicle refers to the maximum climbing capacity of the trackless transfer vehicle when it is fully loaded. Only when the traction of the trackless transfer vehicle is greater than the upward resistance (trackless transfer vehicle retreat) and rolling resistance (air resistance is not counted), the trackless transfer vehicle can climb uphill. Therefore, the engine must have enough power to overcome this slope resistance to make the trackless transfer vehicle go uphill.

Materials in the process of handling often encounter sloped ground, the maximum climb limit in addition to the car itself engine traction is related, but also related to the car's load, slope length, slope height, wheel size, floor.
For trucks with the same road conditions and load size specifications, the maximum climbing angle of the track transfer vehicle is smaller than the maximum climbing angle of the trackless climbing vehicle, and the friction coefficient of the track and the track wheel is lower than that of the trackless rubber wheel and the ground, and it is easier to slide downhill.
For example, the maximum climbing angle of the trackless climbing car with a load capacity of 20t3m*2m wheel width of 35cm is 15° and the maximum climbing angle of the rail car with the same specification is 11°.
