LQ300 down the hole drilling rig for amphibious operations

Since the 1980s, the development of drilling machines has been relatively rapid worldwide. Due to the strong connection mobility between components, centralized and labor-saving operation, and large range of torque and speed changes in hydraulic technology, fully hydraulic drilling rigs have been widely developed and applied. In order to meet the requirements of various drilling process parameters, multifunctional drilling machines that can achieve multi process drilling have been introduced one after another. They can replace several different performance devices with one equipment.
