Focus on the production and development of top hammer rock drilling tools, TBM excavation tools, and raise boring cutting tools.
In 2008, Litian heavy Industry was established in Huludao city, engaged in the manufacturing and sales of rock drilling tools for mines and engineering.
In 2009, introduced foreign advanced TBM disc cutter production technology, began to produce TBM disc cutters. In the same year, the Chengdu office was established, narrowing the gap between the products and many northwest engineering projects.
In 2012, New factory was built in Huludao City, Liaoning Province, which completed the transformation of production from manual control to automatic control, mainly producing TBM cutters and top hammer rock drilling tools. Litian actively participates in the construction of major projects in China and becomes the first manufacturer with full supply of TBM tools in China.
In 2013, a mobile maintenance workshop was developed to facilitate users' maintenance and application; advanced integrated intelligent equipment was introduced, and the production of rock drilling tools was in line with international rock tools processing equipment.
In 2015, according to different geological conditions, new materials were used and new processes were developed, which greatly improved the wear resistance and toughness of the products. Expand the development and production of TBM cutter head accessories, soft ground cutters and other products.
In 2016, the one-stop production line of annealing, machining, carburizing, straightening and surface strengthening of rock drilling tools was put into use. Litian has become long-term cooperation unit with domestic heavyweight construction units such as CRCHI, CSIC, China's hydropower construction bureaus, and has established product service stations in many places.
In 2017, Litian became the largest supplier of hard rock TBM cutting tools in China.
In 2018, Began to develop and manufacture raise boring roller cutters, which has been successfully applied in domestic mines and infrastructure projects with good use effect.
In 2020, the Second factory in Huludao was completed and put into use.
China Railway 18th Bureau Group Tunnel Engineering Co., Ltd
The service life and quality of the TBM disc cutter provided by LITIAN is stable, and there is no abnormal damage such as partial wear and cutter ring fracture in the course of use. The disc cutter has excellent wear resistance and stable performance in passing through hard rock strata, and Litian disc cutter can be trusted.
In 2021, 70% of the disc roller cutter used by our company came from Litian heavy Machinery Co., Ltd. Litian also dispatched after-sales service personnel to assist in cutter loading and maintenance on site, and regularly exchange and study with the project department staff to provide consulting services to fully meet the needs of our project department.

Congratulations to your company for being selected as the 2020 Gold Supplier of China Railway Construction Heavy Industry Group Co., Ltd through the evaluation of the comprehensive capabilities of more than 1,000 registered qualified suppliers. Here, we thank you for your great help along the way, and thank you for your continued trust and support!
Yuxi Feiya Mining Development Management Co., Ltd.
According to the comparison of No. 36 Simba H1354 trolley using different brands of drill rods and drill button bits, Litian drill rods have a longer service life, and Litian drills have better drilling speeds, better slag removal effects, and long service life. In particular, the service life of the drill bit with 14 buttons is greatly improved compared to other brands.
China Railway Tunnel Group One Co., Ltd.
Litian rock tools have been used in our project with remarkable results, and the cost performance is better than other brand rock tool quality. Litan provided rock tool maintenance work and provide professional technical services and technical guidance for our project.
Geological conditions: It is an uneven stratum with the upper part soft and the lower part hard. The upper part of the interval is hard plastic cohesive soil and residual soil, and the lower part is fully and strongly weathered granite. The lithology of the tunnel section is quite different. There are generally 60m long bedrock protrusions in the interval, and the bottom protrusions are medium and lightly weathered granite, which intrude into the tunnel 0.5m-1.1m. The uniaxial compressive strength of the slightly weathered granite rock is as high as 120Mpa. The rock is very hard and extremely difficult to break.
China Railway 22nd Bureau Group Co., Ltd.
The TBM cutters replacement and maintenance service team dispatched by your company has devoted a lot of energy to our service since it came to our project, and went all out to overcome on-site difficulties, saving precious tunneling time for the project department. At the same time, it also demonstrates your company's fine traditions, excellent technology, and perseverance entrepreneurial spirit. For this, our project department would like to express our gratitude to your company.
In this use, Litian shank has reached the service life of the imported high-quality shank adapters, and the service life of Litian drill rods is also equivalent to that of imported high-quality drill rods. In the high-intensity operation, it shows excellent comprehensive cost performance, which is ahead of other similar products.
Chongqing Rail Transit Line 9 Phase II
In the second phase of Chongqing Rail Transit Line 9, the total length from the right line of the TBM section is 1962 meters. Litian TBM roller cutters have been tunneled for 1746 meters in this project. The tunneling thrust is usually 8000KN and the maximum thrust is 12000KN. The TBM cutters' performance is excellent during use, and the cutting tools are not replaced. There are no abnormal damages such as partial wear and disc cutter ring breakage, and the average wear is 1-3mm.
China Railway Twenty-third Bureau Group Co., Ltd.
The whole dress of Litian TBM cutters was digging 1215 meters in the bid section (Huilong-Longma section), and there was no abnormal damage such as eccentric wear or cutter ring breakage during use, and the average wear was 2-4mm. Due to the relatively small wear of the TBM cutters in this section, the cutters can be used in the next section of the 1300-meter.
Yuxi Mining Dahongshan Copper Mine
Litian drill rods are very wear-resistant, hard and tough, and the bolts are not easy to break in bolting.
China Railway Twenty-third Bureau Group Co., Ltd.
The whole dress of Litian TBM cutting tools was boring more than 870 meters in the bid section, and there was no abnormal damage such as partial wear and breakage of the cutter ring during use. In particular, the disc cutter rings exhibit superior wear resistance and toughness in the typical cobblestone formation in Chengdu. Litian TBM cutters have good quality and stable performance.
In this use, Litian drill rods have reached the service life of the imported high-quality drill rods used in the past, which are equivalent to imported ones and are cost-effective.
China Water Resources and Hydropower Fourth Engineering Bureau Co., Ltd.
Litian TBM cutters have been used in our project and have been tunneled for 1,840 meters. Only two single-edged hobs have been replaced. The wear value of the cutter rings is relatively small. It is expected that after the end of the two kilometers, some of the disc cutters can still be used with grease, seals, and bearings. Litian provides comprehensive technical support during the supply period, and the service personnel tracks it in place.
