Features

Strong working pressure and climbing ability

The folding frame track and four-wheel drive are adopted; and track leveling and the walking motor of plunger piston improve the workingpressure and climbing capacity.

Meet the requirements of limitinapositon.

The expanded pitch and lifing-arm hydraulic cylinder enable it to meet the requirements of limitinapositon.

The dust colector is enlarged to produce a better effect on dust coection.

The rotary torque and ravoling speed are rased: the propusion molor and chain are used to ra se the lming force and ralablity The dust colector is enlarged to produce a better effect on dust coection.

The thickened profle folderis used for the housing

The thickened profle folderis used for the housing, thus improv.ing its level of intensity and rigidity, and the additional ring makes handling and lifting convenient
