Project Background
Recently, QLTEK Laser successfully secured a strategic equipment supply project with Lonking Holdings Limited (LONKING), one of China's leading construction machinery manufacturers and a globally recognized engineering equipment brand.
Founded in 1993, Lonking is ranked among the "Top 50 Global Construction Machinery Manufacturers" and is widely known for its strong capability in excavators, loaders, forklifts, and heavy-duty construction equipment.
As the industry continues to move toward intelligent manufacturing and digital production systems, Lonking has been actively upgrading its fabrication and structural component processing capabilities.
To support this transformation, Lonking has introduced QLTEK's high-power laser cutting and tube cutting solutions to enhance production efficiency, precision, and automation level.
Equipment Configuration
The delivered equipment includes:
2 × L2 Dual-Chuck Laser Tube Cutting Machines (6000W)
1 × G18025 High-Power Fiber Laser Cutting Machine (30000W)
1 × G112025 High-Power Fiber Laser Cutting Machine (30000W)
These machines form a combined sheet metal and tube processing solution, designed for high-efficiency structural manufacturing in heavy machinery production environments.
Challenge in Engineering Machinery Manufacturing
In construction machinery manufacturing, production typically involves:
Heavy steel plates for structural frames
Thick plate cutting for load-bearing components
Tube structures for machine arms and support systems
High-strength welded assemblies
Large-scale batch production requirements
Traditional cutting methods often face challenges such as:
Low material utilization rate in tube processing
Limited efficiency in thick plate cutting
High secondary grinding workload
Difficulty maintaining consistency in batch production
Inefficiency in multi-process structural fabrication
As product complexity increases, manufacturers require more stable, high-power, and automated laser cutting solutions.
