    product description

    FEATURES

    • SWDM 280BE adopts the high pressure screw air compressor as the power for impactor to realize the fast drilling. Using hydraulic servo and electric control system, the operation is safe and simple and easy for maintenance. The machine is equipped with double sets power system:  diesel engine and electricity. When the distance for shift of the sites is far, it adopts the form of diesel engine drive, to realize fast travel and avoid to drawing the electricity cable. At the working condition, to shift the hole position by using the electricity power. It is operated with both the manual control (in the cab) and remote control (outdoor of the cab). Drilling the holes less than 14 meters of depth, do not need to connect and unload drilling pipe, saving time and energy, high efficiency. The machine is equipped with hydraulic leveling legs to ensure the accurate drilling angle. The standard equipment includes the impactors, drilling-bits removal device, lifting tools.
    • This machine adopts wet type dust removal device equipped with water heating device in winter, water volume is adjustable. Dry type dust removal device is optional.
