HQR 400D Rotary Drilling Rig
- General Arrangement, Dimensions and Transportation Dimension
Features
1. The main winch is located at the bottom of the drilling mast to offer an excellent angle for checking line work. The unique design in the roll prolongs the service life of the steel line and enhances the construction safety. The excellent pulley design adjusts the steel line to the best position, and enhances the reliability of the overall rotary drilling rig.
2. A supercharging technique allows the crowd pull force to reach 44T and the crowd stroke to reach 14m. This design meets a variety of construction methods.
3. The rotary drilling rig features an original CAT374D engine and up structure. The crawler can adjust between 2900 and 4500mm. Customers can choose the counterweight, and increase the weight to improve stability and reliability.
4. Key parts in the hydraulic system are similar to those in the CAT hydraulic loop. Advanced main and auxiliary hydraulic systems achieve the flow allocation and sensitivity loading according to operation demands and drive functions. These features offer a more reliable performance throughout the construction process.
