CCM400B type open-pit down the hole drilling rig

CCM400B type open-pit down the hole drilling rigIt is developed on the basis of the original CCM400. Great Wall Company has conducted field experiments on the improved CCM400B based on the characteristics of CCM400, making it flexible and versatile, with fast rotation of the drilling arm and accurate positioning. It is mainly used for road construction, earthwork excavation and open-pit mining, water and electricity engineering blasting holes, and rock drilling processes for intended holes. It is an ideal drilling equipment for many users.
The drilling rig operates stably, has high reliability, and is easy to operate and maintain.
