deeprotaryconstruction

JD series multifunctional drilling rigs are suitable for hole drilling in different geological conditions,such as rock stratum,gravel layer,clay layer,aquifer,etc. They have found applications in deep foundation pits of buildings,and in railway,highway,subway,tunnel,geological disaster control,etc. The drilling rigs are able to conduct the construction of grouting reinforcement,anchor rods or cables,mini-piles,swing-jet grouting,geological exploration,support of hole wall,pipe-roof protection,etc. Characteristics 1. The drilling rigs are of modular design, with a rotary-percussive drifter and a rotary drifter optional and interchangeable for different drilling operations. Besides a standard feed mast with a length of 4100 mm, a shorter feed mast is optional to satisfy narrow, low hole-drilling sites. 2. The drill rod gripper assembly provides a flexible configuration to meet the requirements of different drifters for the gripper and achieve highest efficiency. 3. The lifting winch can realize luffing (that is, the lifting positions are adjustable back and forth) for easy lifting operations. 4. The drifter-trolley is configured with a sideway mechanism for easy lifting of the drilling equipment (i.e. rods, bits and so on). 5. The feed mechanism is of stepless speeds. 6. The rotary-percussive drifter is provided with a back-hammering unit which is protected by an operating control. 7. The engine features an accelerator executor for the operator to regulate the throttle at the console. 8. The console is equipped with an elevator mechanism for easy control of the drilling operations.
