In our understanding, the large slag-handling machine is the 160-type crawler slag-handling machine. Why do we say it’s large? Well, we should have a certain familiarity with the models of slag-handling machines—this one is actually the largest among them. So let me take a closer look at the 160-type slag-handling machine.
　　The Model 160 slag-removal machine comes in two types: crawler-type and wheeled. Let’s take a closer look at the large crawler-type Model 160 slag-removal machine. First, it uses crawler tracks for locomotion, making it ideal for use in mine tunnels with steep slopes. Its key feature is its highly efficient bucket, with a working capacity of 160 m³/h. This machine is suitable for tunnel cross-sections measuring 4.2 m × 4.2 m. The discharge height ranges from 2,200 mm (low) to 3,100 mm (high). The digging depth is 5,000 mm, and the digging width is 5,400 mm. The total machine weight is 7,200 kg, and the material dimensions are 1,200 mm × 700 mm. The conveyor belt speed is 0.57 m/s, and the motor power is 30 kW (two 15-kW motors) plus 7.5 kW.
　　Here are some specifications of the Model 160 scraper loader. By examining these parameters, you can get a good sense of the Model 160’s working efficiency. At the same time, tunnels with steep gradients require crawler-type scraper loaders. Since tunnels often have slopes, wheeled scraper loaders simply don’t provide the same level of traction as crawler models. Moreover, crawler scraper loaders can be configured—depending on the direction of the slope—to either use a crawler belt scraper loader or a crawler blade scraper loader. For example, in uphill tunnels, a crawler blade scraper loader is the ideal choice, whereas in downhill tunnels, a crawler belt scraper loader would be more suitable.
　　The large crawler-type muck loader has a fairly broad range of applications—for example, it’s suitable for use in quarries, sand mines, and mines. However, it cannot be used in small tunnels; this is the limitation of the 160-type muck loader. It can only be employed in large-scale construction projects.
