Classic model upgrade: Shanghai Jintai SD30 multi-function drilling rig
The SD30 is an upgraded product of the classic model SD28 of the four-link mechanism rotary drilling rig of Shanghai Jintai Company. On the basis of SD28, SD30 re-optimizes the hydraulic system to improve the effective power output efficiency. At the same time, by increasing the weight of the lower chassis and increasing or decreasing the weight, the pressure and pull-out force of the whole machine is more balanced. In order to increase the rock drilling capacity of the rig. SD30 has the following technical features:
1) Dedicated chassis: SD30 adopts a new generation dedicated chassis of Euro III emission (engine power 299kw). Compared with SD28, SD30's lower chassis is wider, more weight, lower center of gravity, and optional external weight. Improve the stability of the equipment in the construction state;
2) Power head: multi-speed control of the speed, the drilling efficiency is higher; the power head carriage adopts long-oriented three-side wear-resisting structure to ensure the vertical precision of the drilling; double buffer system, the protection ability is improved.
3) Energy-saving and efficiency improvement: multi-pump series, parallel system and special design main valve can be used to rationally distribute power, reduce energy consumption and increase main valve output power;
4) Counterweight: It adopts the recyclable standardization superimposed weight, which can flexibly increase or decrease the weight according to the actual working conditions;
5) The structure of the whole machine is more compact, and the radius of gyration is small (3715mm), which increases construction safety and flexibility of operation;
