In the selection of transportation machinery , the main technical parameters to consider are productivity, delivery speed, filling factor , transmission length and lifting height.

       Productivity

       Productivity refers to the weight of the goods transported mechanical transmission in unit time , which is the main indicator of operating performance of the transport machinery , and its size depends on the weight and speed of work per meter length of the materials contained on the conveyor carrier .

       Conveyor speed

       Conveyor speed is the speed of delivery of materials , the term includes the conveying speed of the belt speed , chain speed and spindle speed. Wherein the conveyor belt or the traction means which is being conveyed in the forward direction of the tape running speed of the goods , is the speed of the traction chain of the chain is conveyed in the forward direction the speed of the goods , the spindle speed is the drum shaft or the drive shaft speed of the transmission chain .

       Filling factor

       Filling factor is characterized by bulk transport pieces of the loan or the degree of fill factor carrier machinery .

       Conveying length

       Mechanical loading conveyor length delivery point and the same distance to start unloading point .

       Lift height

       Lift height is the height of the material to be promoted in the vertical direction .

       In addition, the performance of the technical parameters as well as the safety factor transportation machinery , braking time , start time, motor power, shaft power, mass per unit length of the incoming point traction tension member , the maximum dynamic tension , maximum static tension , pre-tension , taut itineraries .
