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?
The warranty period for new machine is one year or 2000 working hours, whichever comes first will be applied. Please contact with us for detailed Warranty Regulation.

2. What’s your service ?
We can offer professional technical support and good after-sale service to you. Modification methods will be different according to different models and configurations of your owned excavators. Before modifying, you need to provide configuration, mechanical and hydraulic joints and others. Before modifying, you need to confirm technical specification.

photobank (19)This project is a high voltage line project in Hunan Province. KR110D rotary drilling rig is mainly used for the excavation of the foundation. KR110D walking traction is 230KN, with the expandable chassis, it has the ability of slope climbing of 25°. The construction strata:
1. Soil sandwiched stone, strong weathered rock, drilling diameter of 1800mm, drilling depth of 12m, hole forming in 2.5 hours.
2. Strongly weathered and moderately weathered rock, drilling diameter 2000mm, drilling depth 12.8m, hole forming time is 9 hours. KR110D’s excellent operational control, strong construction power, and efficient construction results have won the customer’s appreciation.
