AM-20

AM-20 is a high-performance fully articulated top drive drill equipped with a vertical rotary table and remote-controlled travel system, enabling fast multi-angle hole alignment and safe ramp operation in tunnels.Featuring a load-sensing hydraulic system and turbocharged diesel engine, it is energy-efficient and suitable for high altitudes and harsh environments ranging from -25℃ to 45℃.Configurable with various power heads and stroke masts, it is widely used in complex projects such as tunnel pipe roofing, advanced grouting, micro-piling, anchoring and high-pressure jet grouting, improving construction accuracy and safety while resolving issues of difficult alignment, low efficiency and poor environmental adaptability of conventional equipment.

• •High-stability angle adjustment mechanism with large vertical rotary table enables flexible multi-angle adjustment to meet various engineering needs such as tunnel construction.
• •Remote control travel & crawler swing design, strong trafficability on complex terrain, safe and convenient operation, suitable for various construction sites.
• •Load-sensing hydraulic system with turbocharged diesel engine delivers strong power and high efficiency. Optional Euro 5 engine complies with overseas environmental standards.
• •High torque, high speed and strong power enable fast drilling in sandy gravel, crushed stone and other collapse-prone formations, ensuring hole quality. Construction in high water-bearing formations is available without down-the-hole hammer.
• •Drilling tools transfer impact energy from outside to inside, effectively preventing sticking and burying accidents, thus reducing construction costs and risks.
• •Construction applications: tunnel construction including advanced exploratory holes, horizontal coring, tunnel pipe roofing; various engineering constructions such as foundation pit support, pilot holes, micro-piles, anchoring and reinforcement.
