Product DescriptionZML90 rock anchor drilling machine crawler type drilling rig used for fundation pit ZML90 is a crawler-mounted multifunctional drilling rig primarily used in various engineering fields such as power plants, highway and railway slope stabilization with anchor reinforcement, advance support for tunnel pipe sheds, inclined pile anchor reinforcement for foundation pits, anti-floating anchor rods, geothermal wells, roadbed reinforcement, dam foundation and body anti-seepage treatment in hydroelectric projects, drainage holes, blasting holes in mines and quarries, and micro-pile holes. It is particularly suitable for deep hole drilling and casing advancement in challenging formations like floating, cobblestone, gravel, and fractured highly weathered rock formations. It excels in efficient and high-quality drilling through complex formations and finds wide application in various rock and soil anchoring projects. The drilling rig is equipped with a clamping device that enables automatic unloading of the drill rods. It features a variable pump and a load feedback system, which reduces the probability of getting stuck and allows for normal operation even in high-temperature weather conditions. Additionally, it has a rotating chassis and four hydraulic outriggers, providing enhanced stability and meeting the requirements of multi-angle construction. It performs exceptionally well in building foundation pit treatment and geothermal heat pump construction.
