KUANGYUAN · Henan Mine Crane
China's largest privately-owned crane manufacturer — 110+ models built on 16 robot welding lines, engineered to order and working in 122 countries and regions.
Why Kuangyuan
1.62 million m² of built area, 3,500+ sets of machining equipment and 4,700+ employees make Kuangyuan the largest privately-owned overhead and gantry crane maker in China.
16 robot welding lines, including a 25 m single-girder main-seam line with four welding robots, keep girder weld quality consistent on every order.
Every crane is computer-optimised for its duty case and designed to the latest national standards aligned with international codes.
Products work in 122 countries and regions; references include Baowu, China Railway, MCC, CNNC and AVIC projects.

Product range
Overhead (bridge) cranes cover 46 models in 7 sub-categories, from light single girders to metallurgical, explosion-proof and insulated special cranes for steel, chemical and electrolytic-aluminium plants.
Gantry cranes cover 29 models in 5 sub-categories for yards, rail logistics and shipyards; light and small lifting equipment adds wire-rope electric hoists in 6 models.
Representative cranes
The first batch on this site uses models documented in the client dossier. Reference projects are shown where the dossier names them.

QD type
The mainstream choice for heavy factory lifting — a general-purpose double girder hook crane, computer-optimised and built to order.

LH type
Double girder crane with an electric hoist trolley — better value than a winch double girder at medium duty.

YZ type
Heat-proof double girder foundry crane with redundant safety design for molten-metal handling.

Grab type
Grab crane for ores, coal, coke, slag and furnace charge in yards and boiler houses.

ZJJB clean-room type
Explosion-proof crane with dust-free clean-room treatment for pharmaceutical, electronics and precision chemical plants.

Anode stacking type
Electrolytic-aluminium crane with combined clamp for anode carbon blocks, with weighing and gap monitoring.
Core capabilities
16 robot welding lines with CNC cutting, one-pass forming lines and an intelligent industrial park keep structural quality repeatable.
A national enterprise technology centre, a provincial industrial design centre and a Zhongyuan Scholar work station; 10+ senior experts and 200+ engineers design every crane to order.
A national joint laboratory with the provincial special-equipment inspection institute, X-ray and ultrasonic flaw detection, and a complete machine test bench on every line.
428 sales and service outlets across China provide total solutions and full life-cycle service to 7,000+ mid-to-high-end customers.
Explosion-proof, insulated, metallurgical, clean-room, unmanned and nuclear-grade cranes are engineered from the same platform for demanding industries.
Craftsmanship
The workflow follows the manufacturing process described in the client dossier, from raw material intake to complete machine testing.
Plates for girders and structures are pretreated on intake for coating and weld quality.
Plasma CNC cutting machines cut parts from the order-optimised drawings.
U-shaped channels and cover plates are formed without weld seams on dedicated lines.
Main-girder internal seams and end beams are welded on 16 robot welding lines.
Box furnaces and pit-type tempering furnaces relieve welding stress on key weldments.
Gantry boring-milling centres machine wheels, shafts and gears to tolerance.
End beams, trolleys and hoist components are assembled on flow lines.
X-ray and ultrasonic flaw detection, physical & chemical analysis and gear testing run through the process.
Every crane passes no-load, load and safety-device tests on the test bench.
Final painting, packing and dispatch inspection before leaving the factory.

Intelligent manufacturing
The Kuangyuan intelligent industrial park is a RMB 2.6 billion investment with 740,000 m² of planned building area and a single-shift capacity of 50,000 crane sets, according to the client dossier.
310 sets of intelligent equipment are already networked on the in-house big-data platform, with digitalisation and connectivity rates of 95% and 85% reported for the machine shops.

Custom cranes
Cranes are engineered to order. Buyers submit the duty case — material handled, capacity, span, building or runway layout — plus any industry-specific requirement such as explosion-proofing, insulation or clean-room operation.
The national enterprise technology centre returns a computer-optimised design with drawings and a quotation, and the crane is built, inspected and shipped with installation, spare parts and life-cycle support.
