YCR90 Rotary Drilling Rig
Stable and reliable performance
The pumps, valves, motors and reducers of the machine adopt the core hydrauliccomponents of imported brands, with superior performance, reliability and stability.lt can be widely used for drilling and construction of all kinds of soil layers and rock strata suchas strong weathering, moderate weathering and breezing.t can satisfy the pore-forming technology of many kinds of foundation, such as cast-in-place pile, continuous wall.foundation reinforcement, etc., and can be all-terrain to deal with the construction conditions of varous geological complex working conditions. The overall structure of small and medium-sized products adopts the advanced conceptof rod transportation, with high mobility, and can provide customers with specia customized services according to their needs.
Safety of equipment structure
The five structural parts of the machine, including frame, platform, moving arm and mastadopt new design and upgrade technology, the structure is strengthened and optimizedcomprehensively,and advanced finite element analysis technology is applied tocomprehensively improve the compressive, torsional, bending and seismic resistance ofthe whole machine structural parts, and the service life and safe construction are fullguaranteed. The chassis of the vehicle adoots self-developed special telescopic chassis that issuitable for the actual working condition load of rotary excavation, with super-large wheebase, widening and strengthened slewing bearing, which has super stability, can realizearbitrary construction within 360° range, and adopts heavy four-wheel belt, which isconvenient for transportation and has excellent walking performance.
