Powerful Rotary Head
Lifting chain adopts 28A roller chain, box type large section steel guide rail, to ensure that it has enough strength, one time can push 4 meters.
Strong Heavy Duty Guide Rail
The gyrator is equipped with four sets of hydraulic rotary motors, and adopts high modulus-straight teeth and large reduction ratio transmission to provide the rotary torque of up to 12000Nm for the drilling rig. It is suitable for the construction of foundation pile holes with large aperture
Frame Winch
Equipped with 1 ton frame winch for feed(optional), convenient for hoisting drill bit and drilling tool,impact device, etc. When used on large slopes, you can choose to use 8-ton frame winch for rig(optional) to ensure sufficient traction when using the drill rig.
Diesel Engine
Equipped with 86KW diesel engine, efficient desert-air filter,the maximum hole diameter can reach 500mm.
Oil Cylinder & Hydraulic System
Optimize oil cylinder,upgrade hydraulic system.The hydraulic cylinder is more reliable, the system flow is increased.Hydraulic system adopts high pressure cast iron pump.
Crawler
Widened and thickened walking track plate; Add track leveling cylinders.
