Updated AKL-150Y diesel engine bore well drilling machine, now we adapt cooler for the hydraulic system, in that way to ensure the hydraulic system work well all the time. As we know, the hydraulic oil will get hotter and hotter during working, if no cooler, the hydraulic power will be much weaker, so cooler system is a must for the hydraulic system, This AKL-150Y use hydraulic motor and hydraulic lifting. so hydraulic system is the very important part for the drilling rig.
