Descrição
Descrição detalhada
Descrição
Double large triangular back variable amplitude mast
The deformation of the drilling mast in hard rock is minimal, and the verticality of the borehole is high; The mast can be placed backwards, and there is no need to dismantle the mast during transfer, resulting in high transfer efficiency
Three speed reduction power head
Low speed and high torque, strong rock penetration ability in moderately and weakly weathered rock layers, and can be used with a down the hole hammer to drive hard rock piles
Mid mounted single row rope main winch
Single layer drum, low wear and longer service life of steel wire rope, lifting speed of 72m/min, high soil lifting efficiency
Strengthen chassis+large slewing support
Low center of gravity design, strong stability for heavy load and steep slope construction, traction force of 557kN
Intelligent electronic control
360 ° panoramic monitoring, remote viewing of working conditions/fuel consumption/faults through mobile app; Multi speed power adaptive soil layer, fuel-efficient and efficient
