Product DescriptionRotary Drilling Rigs Soil Investigation Drilling
Rig XR320D for Foundation Construction Work Rotary
Drilling Rig widely used in boring operation of bored concrete pile
in foundation engineering of highway, railways, bridges, ports,
docks and high-rise buildings. It adopts dedicated hydraulic
retractable crawler chassis and heavy slewing bearing and has high
stability. It adopts the luffing mechanism of large triangle form
to ensure the stability of construction of big holes and deep piles
in hard formation. It adopts the front-located single-rope main
winch structure to greatly prolong the service life of steel wire
rope and lower the use cost. According to specific working
conditions, the users can select a corresponding gear of the
Cummins turbo-supercharged engine with three gears, getting the
drilling rig working as three engines. Unit head can switch between
Normal Mode and Rock Cracking Mode which are applicable for soil
and rock excavation respectively, improving the efficiency; Winch
pressurization and sleeve drive are both available for selection to
meet users' various demands. It is equipped with a centralized
lubrication system as standard configuration; maintenance is
easier. The complete machine has passed CE certification of TV
Rheinland group.Functionsoil investigation,
