The General Situation of Machine

1. This kind of crawler drilling jumbo can save energy. For some excellent drills, the required power of hydraulic system is only one-third of the power loss of pneumatic drill. The power loss is small, so it can save energy.
2. The rock penetration performance of the crawler drilling jumbo is well and the speed is fast. If the rock type and the aperture are similar, the rock drilling speed of this hydraulic drill machine will be more than two times than the pneumatic drill machine.
3. The cost of drill pipe is low. Because the hydraulic drilling parameters can be adjustable, we can choose the optimum drilling parameters in different rock conditions. The hydraulic impact stress wave is quietly and the transfer efficiency is high, therefore, the drilling tool and drill rod can save 15% to 20% of the cost.
4. It can reduce the cost of rock drilling. The high pressure of hydraulic system is high. Therefore, in the same impact speed the piston stress area of hydraulic drill machine is small. The piston impact area is close to the drill rod area. The stress deliver loss of this kind of machine is small. It has the traits of even stress, long life, less malfunction, so it can reduce the cost.
5. The crawler drilling jumbo can improve the working environment and reduce noise. This machine can not give out harmful and waste gases during the process of hydraulic rock drilling. Therefore, there is no waste gas and oil pollution toward the environment. It improves the visibility of the work area and improves the operation environment. In addition to the emission of metal clang, there is no the voice of exhaust emission during the hydraulic rock drilling. It can reduce 5 ~ 10 decibels of the noise than the pneumatic rock drilling.
6. This machine can improve the construction quality. This drill car can guarantee the accuracy of the drilling depth and distance. After the blasting of hydraulic rock drilling the size and surface of the roadway is neat. Therefore, it can improve the quality of construction.
7. The drill is favorable for safety production. Because the operating location of the driver is far away from the working face and the operator work under protective cover, it can prevent the empty top operation and it will be helpful for safety production.

1. After the constant update of a few generation products, the hydraulic system design of the machine is reasonable. The main parts of the machine are from the famous brands at home and abroad, which ensure the stability of the machine.
2. The hydraulic system is open type, so the operator can control more easily.
3. The hydraulic system adopts the pure imported load feedback system.
4. The hydraulic spiral swing oil cylinder has the obvious virtues of compact structure, small space occupy, safety and reliability, no maintenance, no leakage under high pressure, great output torque when compared with "DF hydraulic spiral put oil cylinder", the traditional gear put oil cylinder and the blade-type oil cylinder. The hydraulic spiral swing oil cylinder is almost applied to every occasion where high torque swing movement is needed. The standards angle of most models provided is 0 ~ 360°. We are widely known for the novel design of the hydraulic spiral swing oil cylinder and engineering equipment accessories. The product we designed can provide great torque in compact space, unusual load support and solid, reliable performance. The technology fills the gap in the domestic field. It obtains the national invention patents and the utility model patents. We have established the continuous effective quality guarantee system. Meanwhile, we have the ability of fully independent product design, manufacturing and supporting.

Jackdrill
1. The energy consumption of this kind of jackdrill is low. The energy of the whole install is 15 KW. When drilling the same rock borehole the energy consumption is only 1/3 of wind consumption. The volume of jackdrill is small and the weight is light. However, the impact energy is more than 85 joule. The impact frequency is high. The drilling speed is over 800 mm when drilling the granite whose hardness is 14 and borehole is φ 40 mm in one minute. It means when the jackdrill work continuously, it can drill the rock about 50m in one hour.
2. The scaffold of jackdrill can fully guarantee the verticality of hole drilling and the equality of vertical borehole.
Carriage

The jackdrill adopts the special technical carriage which is researched independently. It has the traits of compact structure, light weight and strong rigidity. According to the different requirements, we can change the different length of the carriage. For example, when the short carriage is installed, we can drill anchor stock hole.

Ceiling

The jackdrill is equipped with the safety, elevating ceiling which can meet the requirements of FOPS.

Optional Parts
Hydraulic Control System

Due to the fluctuation of water supply system, water shortage and other reasons, the pressure of water effluent is low during the use of drill carriage. It can affect the normal drilling and slag discharge. Therefore, it will cause the borer obstruction and the borer block, etc. Hydraulic control System is through the detection towards the pressure of water effluent to control the impact of homework. It can avoid the above phenomenon. Therefore, it can protect the drilling car and drilling tools.

Diesel Power The diesel power has two types. Both of them adopt small power diesel engine for walking. The customer should ask specifically if they need high-power diesel engine for work. Cable Drum This kind of cable drum can make the other equipment charge and discharge the cable freely. It can save manpower and improve safety coefficient.
