KR90A rotary drilling rig is widely applied in pore-forming work of the cast-in-place concrete pile in construction of foundation works, such as highways, railways, bridges, ports and high-rise buildings. Drilling with friction type and machine-locked drill rods. KR90A is equipped with the CLG chassis of extraordinary stability and reliability. The chassis adopts a heavy-duty hydraulic crawler to provide transport convenience and excellent traveling performance. It adopts the CUMMINS QSF3.8 electric control turbo-supercharged engine to provide strong power and conformity with Euro III emission standard.

1. KR90A pile driver is a relatively small pile driver with high use efficiency, low consumption of oil, and flexible and reliable use.
2. The hydraulic pressure system of KR90A rotary drilling rig adopted threshold power control and negative flow control the system acquired high efficiency and higher energy conservation.
3. KR90A rotary drilling rig equipped with a drilling depth measurement system displaying the reading in much higher precision than that of an ordinary drilling rig. New design of two-level operation interface is adopted for simpler operation and more reasonable man-machine interaction.
4. High-safety design according to European Union Safety Standards EN16228 compliances meeting the requirements of dynamic and static stability, and the weight distribution is optimized for higher safety, better stability and safer construction. And KR90A rotary drilling rig already passed CE certificates for Europe.
The KR90 small rotary drilling rig of Tysim machinery has been successfully entered the African country of Zimbabwe for construction. This is the second African country where Tysim piling equipment have entered after the KR125 entered Zambia. The KR90A rotary drilling rig exported this time is a leading brand of small rotary drilling rig of Tysim, which uses a customized chassis with Cummins engine mature excavator technology to build a high-end small rotary drilling rig for the international market.
1: What is the Warranty of the Rotary Drilling Rig?
