Yuchai YCR405 rotary drilling rig is equipped with Cummins engine

It is a large-scale rotary drilling rig developed by Yuchai rotary drilling specifically for rock-entry conditions, with a drilling diameter of up to 3 meters, a maximum drilling depth of up to 99 meters, a maximum torque of 405 kN-m, and a weight of up to 120 tons under the working condition, matched with the telescopic chassis special for rotary drilling rigs, which is of largest size compared with competitors in the same class, and is more conducive to the actual output of each main parameter. The actual output of the main parameters, high working efficiency and strong power, can quickly and accurately complete the pile foundation construction, thus greatly shortening the construction cycle. The new generation of electronic control system integrates a number of automatic intelligent controls, such as automatic drilling, automatic soil dumping, rotary self-reset, and multi-gear intelligent control mode of the power head. The single-row rope main winch structure effectively avoids the "rope biting problem" and greatly extends the life of the wire rope. Standard equipped with centralized lubrication system, maintenance is more convenient. The equipment adopts imported brand Cummins engine, EFI large displacement technology, enough power reserve technology, strong power, can realize the construction in deep hole, large diameter, hard ground and other harsh working conditions. The equipment is widely used in high-speed bridge construction and other projects.
