In 2014, as the high-speed rail construction boom subsided and demand for roadbed bridges decreased, driven by regional investment, industrial and civil construction became the main growth point of economic development in recent years, while rail transit, water conservancy projects, and urban circle construction became future investment hotspots; at the same time, the construction areas for rotary drilling rigs shifted southward, with operations mainly focusing on hard rock construction, requiring higher rock-socketing capabilities of the drilling rigs; and karst caves, quicksand, and groundwater placed higher demands on the rigs' construction method support and supporting processes; the global economic recovery, the rise of overseas investment, and the export of high-speed rail technology have led to the resurgence of medium-sized rotary drilling rigs originally suited for high-speed rail construction.

 

 

“King Kong Stands Proud” Lovol Rotary Drilling Rig Fully Upgraded

 

　　In light of current market conditions and taking product quality improvement as an opportunity, Lovol Rotary Drilling Rig actively carried out product upgrades and launched the “King Kong” series rotary drilling rigs, focusing on the 15-ton-meter class economical and efficient models suitable mainly for industrial and civil construction, the 28-ton-meter class highly efficient and reliable models suitable for hard rock construction, and the 22-ton-meter class optimized and upgraded models suitable for composite strata and overseas construction.

　　The Lovol “King Kong” series rotary drilling rigs basically meet the market demand for both large and small models, while also addressing domestic and international demand for medium-sized models. The products cover foundation construction for industrial and civil construction, rail transit, port bridges, water conservancy and energy projects. The series fully covers market hot-selling products of 10-ton-meter, 15-ton-meter, 22-ton-meter, 28-ton-meter, and 40-ton-meter classes. The Lovol “King Kong” series rotary drilling rigs use Lovol dedicated chassis or Caterpillar chassis as the carrier, combining Lovol's mature technology and industry-leading supporting resources to create cost-effective small and medium-sized rotary drilling rigs and highly efficient and reliable large and super-large rotary drilling rigs that meet market demands. 

　　During product development, the Lovol rotary drilling rig R&D team conducted hundreds of person-times of market research based on the latest market working conditions and geological changes, covering hot-selling regions such as Sichuan-Chongqing, Yunnan-Guizhou, Yunnan-Guizhou, Guangdong-Guangxi, Shandong, and Shanxi, traveling tens of thousands of kilometers. The R&D personnel conducted in-depth analysis and comprehensive investigation of all repair items that occurred in previous products, and applied a series of the industry's latest technologies and construction method resources to carry out more than ten major improvements and upgrades on the products, including hydraulic and electrical upgrades, pipeline optimization, structural reinforcement, and power head structure optimization, reflecting Lovol's product philosophy of taking customer needs as the starting point and market development as the focus.

　　In terms of product configuration and selection, the Lovol “King Kong” series rotary drilling rigs emphasize reliability design. Small and medium-sized models are guaranteed by the mature supporting resources of Lovol excavators, with Isuzu and Cummins engines providing economical and efficient power output, and Kawasaki and Rexroth hydraulic and electrical control systems providing precise and accurate response output. Under the same load, fuel consumption is reduced by more than 10%. Large and super-large models use the Caterpillar chassis as the platform, aiming at multiple safety prevention and performance improvement, adopting power heads with high-strength multiple damping design, advanced slewing locking, rear-mounted main winch, upgraded protection, and other strengthening measures. Structural strength is increased by 31.5%, and rock-socketing efficiency is improved by more than 20%. At the same time, guided by FMEA failure mode and effects analysis technology and guaranteed by PDI (pre-delivery inspection) measures, the design concept of high reliability is effectively realized.

　　In terms of equipment construction application, the focus is on improving product operating efficiency. Dual-pump confluence technology is adopted to increase the main winch working speed and shorten the operation cycle time; multi-stage control of the power head is adopted, and with multiple construction modes, geological adaptability is improved to achieve full-condition operation; optimization is carried out in the luffing mechanism, shaking slag discharge, seismic and torsional resistance, drilling tool combination, etc., comprehensively improving equipment construction efficiency. In addition, the product R&D team, combining nearly ten years of product design and use experience of Lovol rotary drilling rigs, optimized and upgraded the product's use, maintenance, repair, transportation, production, and design aspects.

　　“Splitting mountains and breaking rocks, Lovol King Kong; diamond quality, inheriting classics.” Over the past decade, Lovol rotary drilling rigs, with continuous efforts in quality, service, and construction method support, have become a good helper for users to start businesses and become rich; for example, the Lovol FR630D rotary drilling rig was honored as one of the 2013 China Top Ten Piling Machinery Products. The Lovol “King Kong” series rotary drilling rigs launched this time are products with outstanding competitiveness introduced by Lovol rotary drilling rigs on the basis of inheriting excellent quality through continuous product upgrades, management upgrades, and verification upgrades.

　　It is understood that in the coming years, Lovol rotary drilling rigs will continue to actively explore hydraulic and electronic control upgrades and strengthen cooperation with world-class brands such as Caterpillar, Rexroth, Kawasaki, and Cummins; focusing on creating safer, more reliable, economical, and efficient Lovol rotary drilling rig products to increase customer returns. In terms of construction method research, Lovol rotary drilling rigs strive to provide users with comprehensive support including engineering appraisal, construction method support, skill training, drilling tool optimization, drilling fault handling, and equipment improvement and upgrading, solving users' worries.
