Hydraulic Drilling Rigs
In Top Hammer Drilling the hammer produces a percussive force on the drill rods or tubes, which is transmitted to the drill bit. The feed device is usually attached with a hinged boom to a mobile unit. The percussive system strikes the drill rod, for example 2,000-5,000 strikes per minute, and the rotation speed can be, for example, 60-200 rounds per minute. Together these elements make it possible to drill holes in the hard rock. The excess material (cuttings) is flushed up from the bottom of the hole by means of pressurized air or water. Top hammer drills are primarily used in mining, construction and quarrying of rock material. Top hammer drilling, combined with the “drill and blast” method, makes the whole excavation process extremely efficient.
SINOWAY SWDH102S Hydraulic Top-hammer drill rig, and is the ideal choice for surface mining or pre-split drilling in large quarries or open pit mines and construction sites. It is easy to transport and set up at almost any kind of site. The drill rig is operator friendly and thanks to easily accessible service points – very easy to maintain.

Highlights
Equipped with Cummins engine, turbo charge, and the air compressor and hydraulic pump are directly connected to egine to ensure maximum transmission of power and minimization of energy loss.
Hydraulic rock drill with independent intellectual property rights own the shanks rebound energy absorption debice.The working life of drill tools can be guaranteed;Machine reliability has stood the company strengthened test and jobsite application ordeal.
The floating hinged undercarriage allows for 10 degree adaptive floating,a nd a maximum gradeability of up to 30 degree give them extremely good rough terrain capacity.
An automatic drill rod chamber equipped with bionic manipulator, where the drill rods are arranged like a turnable when the rig rotates, enabling the extension and removal of drill rigs through a mere handle, which greatly reduces the operating difficulty and improves the efficiency and reliability. The rotation and feed in the extension and removal of drill rods are adaptively controlled through hydraulic pressure,which reduces the wear of threads on the drill rods and thus improve their service life.
The cooling system has two radiators,which enable the air conditioner and the hydraulic oil to dissipate heat separately, even at a teperature close to 50 degree.
