The company’s establishment date is independently listed as September 22, 2015, while its own materials describe the company as established in 2015.

Hunan Lieyan Technology was established in 2015 in Yongzhou, Hunan Province. The company developed around the engineering challenge of breaking and excavating hard rock using hydraulic and mechanical methods rather than relying exclusively on conventional explosive blasting.

Its early and continuing focus has been rock-drilling machinery, hydraulic drilling systems, rock splitters, and associated equipment. A patent record also shows Hunan Lieyan Technology becoming the assignee of a patent for an automatic lubrication device for a splitting machine, following a transfer registered in 2017.

The company’s corporate profile describes it as a technology-oriented machinery manufacturer serving open-pit mining, tunnelling, geological exploration, slope anchoring, blasting/crushing, and industrial construction applications.1

LIEYAN’s product range is centred on equipment for drilling, splitting, and excavating hard rock.

Integrated hydraulic rock drill and splitter machines

These are among the brand’s most distinctive products. Instead of treating drilling and rock splitting as two completely separate operations, the machines combine the processes into an integrated system.

The PL1000L, for example, is designed for installation on excavators in the approximately 24–36-tonne class. Published specifications list a 22 kW drilling system, drilling depths of up to 1,600 mm, and a hydraulic splitting system.

Other models promoted by the company and its distributors include:

• PL1000L
• PL1500L
• PL2000L
• Other customised/integrated rock-drilling and splitting configurations

The PL2000L is marketed as a larger integrated system intended for demanding hard-rock applications.2

Hydraulic rock drills

LIEYAN also produces hydraulic rock drills intended for drilling holes in hard rock before splitting, excavation, or other engineering operations. These machines are relevant to:

• Open-pit mining
• Quarrying
• Foundation excavation
• Tunnelling
• Geological engineering
• Slope stabilisation
• Anchor-hole drilling

Excavator-mounted drilling equipment

A major aspect of the LIEYAN product philosophy is adapting hydraulic drilling and splitting technology to excavators. This gives the equipment the mobility and positioning capability of an excavator while adding specialised rock-drilling or rock-splitting functions. The company’s current product portfolio includes excavator drill attachments and related equipment.3

Hydraulic rock splitters

Hydraulic splitting machines are designed to fracture rock through controlled hydraulic force. This approach can be particularly useful in situations where conventional blasting is undesirable because of:

• Nearby buildings
• Vibration concerns
• Restricted work sites
• Noise limitations
• Urban construction
• Underground excavation
• Safety or environmental restrictions

LIEYAN markets its technology specifically around non-explosive rock breaking.3

Supporting equipment

The broader product range includes equipment such as:

• Hydraulic drifters
• Handheld rock-drilling/splitting equipment
• Hydraulic power and drilling components
• Air compressors
• Rock-drilling accessories
• Excavator attachments
• Related drilling tools and components3

The central idea behind LIEYAN is mechanical/hydraulic rock fragmentation without conventional explosives. A typical process follows this sequence:

1. Position the machine
2. Drill holes
3. Insert/use the splitting system
4. Apply hydraulic force
5. Fracture the rock
6. Remove the broken material

This makes the technology particularly relevant when blasting would be difficult or prohibited. The company describes its equipment as being intended for non-explosive mining and rock excavation, with technological development focused on improving efficiency, reliability, and practical applicability.

The PL1000L is one of the more publicly documented LIEYAN models. Published specifications include:

• Drilling power: 22 kW
• Borehole diameter: approximately 115 mm
• Maximum drilling depth: 1,600 mm
• Drilling speed: approximately 1 m/min
• Splitting depth: 1,000 mm
• Maximum thrust force: 40 kN
• Maximum splitting force: listed as 80 kN in published specifications
• Rotation angle: 120°
• Machine dimensions: approximately 4,140 × 1,500 × 1,570 mm
• Recommended excavator: approximately 24–36 tonnes

Some marketplace listings contain unusual unit conversions or formatting errors; engineering specifications should ideally be confirmed directly with LIEYAN before being used for procurement or technical design.

LIEYAN equipment is designed for a relatively broad range of heavy-engineering environments.

Mining

The machines can be used for hard-rock excavation and mining where controlled mechanical fragmentation is desirable.

Quarrying

Hydraulic drilling and splitting can be used to break rock without conventional explosive blasting.

Tunnelling

The equipment can assist with rock excavation in confined environments and projects where blasting may be restricted.

Foundation excavation

One example published by LIEYAN describes a project involving a 10-metre-deep underground garage where nearby residential buildings prevented conventional blasting. Two PL1000L machines were used for hard-rock excavation. The company reported that excavation efficiency increased approximately threefold compared with the hydraulic-breaker method used previously. This is a company-reported case-study result, rather than an independently verified benchmark.4

Civil engineering

Potential applications include:

• Building foundations
• Underground garages
• Roads
• Municipal projects
• Infrastructure construction
• Rock excavation around existing structures

Slope and geological engineering

The company’s equipment is also associated with drilling for slope anchors, geological exploration, and related engineering work.1

According to company information, LIEYAN operates manufacturing facilities in Yongzhou, Hunan. Its current company profile states that it has a 40,000 m² building area, including an approximately 18,000 m² factory, more than 120 CNC and testing machines, and more than 80 employees. The same source reports cooperation with universities including Central South University, National University of Defense Technology, and China University of Mining and Technology.

A separate industrial marketplace profile gives similar figures and identifies the company as a manufacturer, exporter, and supplier of rock-drilling and rock-splitting machinery.

R&D is an important part of LIEYAN’s positioning. The company reports 83 patents, including 13 core patents related to rock-drilling and fracturing machines. It also states that it has collaborated with universities on R&D projects.

Its patent history provides evidence that the company has developed proprietary technologies around rock-splitting equipment and hydraulic systems. For example, the Chinese patent database records a patent concerning an automatic lubrication system for a splitter, with Hunan Lieyan Technology subsequently listed as the assignee.

Although headquartered in China, LIEYAN positions itself as an export-oriented manufacturer. Company and marketplace materials identify overseas markets including:

• India
• Brazil
• Southeast Asia
• Africa
• South America
• Middle East
• Other international construction and mining markets3

The company’s international strategy appears to focus particularly on countries and regions with significant mining, infrastructure development, and hard-rock excavation activity.

LIEYAN’s brand identity differs considerably from consumer machinery brands such as Caterpillar or Komatsu. Rather than being a general-purpose heavy-equipment manufacturer, LIEYAN is positioned more narrowly as a specialist technology manufacturer for hard-rock drilling and controlled rock fragmentation. Its key positioning can be summarised as:

Hydraulic technology + hard-rock drilling + non-explosive rock breaking + excavator integration

This specialisation allows LIEYAN to compete in applications where conventional hydraulic breakers or explosive blasting may be inefficient, impractical, or restricted.

LIEYAN’s main differentiating characteristics include:

Specialised product focus

The company concentrates heavily on rock drilling, splitting, and related hydraulic equipment rather than producing a broad range of construction machinery.1

Non-explosive excavation

Its products are specifically promoted as solutions for situations where conventional blasting is undesirable or unavailable.

Excavator integration

Several systems can be mounted on excavators, providing mobility and positioning capabilities.

Integrated drilling and splitting

Products such as the PL-series machines combine drilling and splitting operations in a single platform.

Export orientation

The company has developed international distribution and export channels, with products promoted across multiple regions.

LIEYAN’s company materials state that its production system has passed ISO 9001 quality-management certification. The company also identifies itself as a Chinese High-Tech Enterprise and a “Little Giant” enterprise—a designation associated with specialised, innovative small and medium-sized enterprises in China.

These are company-reported credentials and should be independently verified against the relevant certification or government databases when they are important to a procurement decision.

The company describes its approach around:

• Customer orientation
• Manufacturing quality
• Technological innovation
• Continuous improvement
• Service
• Value creation

Its materials emphasise the idea of using technological innovation to provide more efficient rock-breaking solutions and to promote non-explosive rock-mining technology.

The Chinese name 烈岩科技 can be romanised as Lieyan Technology. The company and its machinery are also presented internationally as LIEYAN, while product listings frequently use LIEYANKEJI as the trademark/brand name. For example, the PL1000L marketplace listing explicitly identifies LIEYANKEJI as its trademark.

“Keji” (科技) literally refers to technology/science and technology, making LIEYANKEJI essentially the branded form of “Lieyan Technology.”

LIEYAN is best described as a specialised Chinese B2B industrial machinery brand, rather than a consumer-facing brand. Its parent company, Hunan Lieyan Technology Co., Ltd., was established in 2015 and is headquartered in Yongzhou, Hunan. Its principal technological field is hydraulic rock drilling and non-explosive rock fragmentation.

The company’s best-known equipment includes integrated hydraulic rock-drilling and splitting machines such as the PL1000L, PL1500L, and PL2000L, along with hydraulic drills, excavator attachments, splitters, and supporting components.3

Its target industries include mining, quarrying, tunnelling, foundation excavation, geological engineering, slope engineering, and civil construction.1

Note on founding date

While one LIEYAN-branded website states that “Lieyan Technology was founded in 2009,” the company’s corporate information, Chinese business records, LinkedIn profile, and multiple industrial profiles consistently identify Hunan Lieyan Technology Co., Ltd. as established in 2015 (September 22, 2015). Therefore, 2015 is used as the company’s founding year unless LIEYAN itself provides documentation explaining the 2009 date.4
