Advantages
1. The latest version of the system optimizes some of the drilling assistance operations, making the operation smarter and easier than before. This upgrade can further reduce maintenance costs by 20%: extended maintenance cycle, reduced hydraulic oil consumption; elimination of pilohydraulic oil filter; Replace the shell drain filter with a magnetic filter; the new air filter has a stronger ability to accommodate dust; Fuel and oilfilters are "in one room"; superior part versatility reduces customer maintenance costs.
2. The TR158H rotary drilling rig adopts the new CAT electronic control chassis, and the upper frame is reinforced, which makes the working reliability of the wholemachine significantly improved.
Features
3. The TR158H rotary drilling rig whole machine adopts the electronic control system control, the sensitivity of the components is improved,and the work efficiency is improved.
4. The pilot pump and the fan pump are eliminate (using the electronic fan pump) increases the net power of the hydraulic system.
5. The power head of TR158H rotary drilling rig increases the guiding length of the drill pipe, prolongs the service life of the power head, and improves theaccuracy of the hole forming.
6. The power head of TR158H rotary drilling rig adopts a flip-chip gear box to reduce the maintenance cost.
