SINOVO
1 / 3
The machine is equipped with Cummins engine or electric power as the client’s special request.
Hydraulic rotary head and break in-out clamp device, advanced motor- chain feeding system, and hydraulic winch are reasonable matched.
This rig can be used by two drilling method in set covering layer and stratum soil condition.
The rig can be either crawler, trailer or truck mounted.
Use of efficient and durable oil mist device and oil mist pump. In the process of drilling, the high-speed running impactor is lubricated all the time to extend its service life.
Conveniently equipped with air compressor and DTH hammer, it can drill the hole in rock soil condition by air drilling method.
The rig is adopted with patent technology hydraulic rotating system, mud pump, hydraulic winch, which can work with circulation drilling method.
Two-speed hydraulic regulation is used in rotating, thrusting, lifting system, making drilling specifications match well working situations.
Separate air-cooled hydraulic oil cooler is standard; water cooler option is available for continuous efficiency in high temperatures.
Four hydraulic support jacks level the undercarriage rapidly. The optional support jack extension allows for easy self-loading onto trucks.

The SNR1200 drilling rig is capable of drilling to a maximum depth of 1200 meters.
It is designed for water wells, monitoring wells, ground-source heat pump air-conditioning projects, blasting holes, bolting and anchor cables, micro piles, and other vertical drilling applications.
The drilling rig is highly versatile and can be configured as crawler-mounted, trailer-mounted, or truck-mounted to meet specific operating requirements.
It supports multiple drilling methods, including reverse circulation by mud and by air, down the hole (DTH) hammer drilling, and conventional circulation.
The rig is powered by a Cummins engine or an electric motor upon request. It features two-speed hydraulic regulation for rotating, thrusting, and lifting, which helps match specifications with actual well conditions.
The hydraulic system features a separate air-cooled hydraulic oil cooler, and a water cooler option is also available to ensure continuous and efficient operations under high-temperature conditions.
