container.
3.2 carrying device
A device capable of carrying an item and operating with a lift traction part.
3.4 conveying rate
The number of pieces conveyed in a unit time.
4 Types and basic parameters
4.1 Types
Conveyors are divided into type Z, type C, type E according to the conveying method,
as shown in Figure 1.
4.2.1 Conveying speed
The conveying speed shall preferably use the values specified in Table 1.
4.2.2 Width of carrying device
The width of the carrying device shall preferably be the value specified in Table 2.
5 Technical requirements
5.1 Working environment conditions
5.1.1 The working environment temperature is -5℃~+40℃.
5.1.2 The altitude of installation and use site shall not exceed 1000m. When it exceeds
1000m, the capacity of the motor shall be verified according to the provisions of GB/T
755.
5.2 Overall performance
5.2.1 The conveyor shall run smoothly without abnormal noise.
5.2.2 When the conveyor is running, there shall be no jamming and falling of goods.
5.2.3 The connection point between the carrying device and the lifting traction part in
the vertical lifting section shall be in a horizontal state. There is no obvious concave
phenomenon in the middle when loading.
5.3 Main parts
5.3.1 Traction part
When metal chains are used as traction parts, the chains shall meet the requirements of
GB/T 1243.
5.3.2 Carrying device
The mechanical properties of the material for the carrying device shall not be lower
than Q235A specified in GB/T 700-2006 and 6061 specified in GB/T 6892-2015.
5.3.3 Lifting transmission mechanism
