The DWS series single arm anchor rock drilling rig includes three models: DWS70, DWS90, and DWS31, which are specialized equipment developed for tunnel staggered support construction. This series of equipment is compact in size, flexible in mobility, and easy to operate. It can efficiently complete excavation and anchor hole operations for medium and large tunnel methods such as step method, CD method, core soil retention, and full section excavation of medium-sized tunnels. Specially suitable for parallel construction of multiple units using the up and down guide step method, it can perfectly replace manual wind drilling operations and has significant advantages in the construction of radial anchor holes, advanced support holes, locking foot holes, grouting holes, and anchor cable holes.

Efficient high-power hydraulic rock drill
Adopting Swedish technology international brand rock drills, our company provides various rock drilling machine configuration schemes for users to choose from, considering the rock drilling performance of surrounding rock structures. Different rock drills have different drilling costs, which enables higher drilling rates, shorter cycle operation time, longer drilling tool life, higher production efficiency, and lower drilling costs; Equipped with the standard Wosted A18D high-power rock drill, with a drilling power of 18KW, it can almost handle most rock situations. The dual buffering system can effectively reduce the consumption of drilling tools, making rock drilling work more cost-effective and efficient, and reducing operating costs.
Safe and efficient hydraulic control system
Adopting internationally renowned hydraulic systems, the optimized hydraulic control system ensures smooth and flexible movements, making operation more comfortable.
The safety alarm system and self diagnostic system provide higher operational assurance for the equipment.
The rock drilling system is equipped with automatic anti sticking fiber function, automatic fiber withdrawal and stopping rock drilling function after rock drilling is completed, and two-level protection functions of anti sticking and anti air hitting, which can reduce the consumption of fiber tools.
