DW1-31 Wheel Drilling JumboFeatures of DW1-31 Wheel Drilling Jumbo: 1. Hydraulic Drill Boom. 1) High Efficiency: Unique translation design of drill boom improves accuracy and parallelism of borehole spacing, which achieves accurate and quick positioning. 2) Flexible Movement: Rotary motor in the front of upper arm makes the whole feed mechanism move flexibly (± 180°).

DW2-50 Wheel Double Booms Drilling Jumbo Special design heavy duty with double tripod suspension for accurate hydraulic parallel holding in all directions. The rotary actuators is located in front of the boom, it can make the feed mechanism to rotary ±180 degree. The heavy duty slider with high bending and torsion resi- stance, the working life is longer. The surface of slider covered by stainless steel sheaf.

DW1-24 Wheel Drilling JumboIntroduction of DW1-24 Wheel Drilling Jumbo: 1) DW1-24 Wheel Drilling Jumbo can apply to the excavation drilling in the mining, hydropower tunnel, railway, road and other underground tunnels. If's full hydraulic drilling and traveling with diesel engine. 2) The hydraulic parallel holding can make sure the hole depth and space between, and improve the quality of blasting.

DWE1-31N Wheel Single Boom Drilling Jumbo1. Hydraulic boom Hydraulic boom with double tripod suspension for accurate hydraulic parallel holding in all directions; Direct, fast, easy operation, good accuracy and accurate positioning between holes. American HELAC rotary actuators with high rotation torque, high load capacity, no position shift, compact, good anti-pollution capacity, heavy-duty etc.

DW1-90 Single Boom Drilling Jumbo1. Hydraulic boom Hydraulic boom with double tripod suspension for accurate hydraulic parallel holding in all directions; Direct, fast, easy operation, good accuracy and accurate positioning between holes; American HELAC rotary actuators with high rotation torque, high load capacity, no position shift, compact, good anti-pollution capacity, heavy-duty etc.

DW2-120 Wheel Drilling JumboDW2-120 two booms drilling jumbo is specially designed for tunnels of high-speed railway, water conservancy and hydropower projects, national defense and other medium and large-scale tunnel excavation and drilling operations. It can meet the needs of drilling various blast holes, anchor bolt holes, small pipe support, grouting holes, etc. Two sets of independent hydraulic systems of drill booms are used to control each other without interference. A set of aerial work platform is designed for auxiliary work such as blasting charge, danger elimination, mesh hanging, etc.

DW3-180 Three Booms Drilling JumboWeight: 5000kg
Overall dimension: 16789*2926*3117 / 4917 mm;
Working scope (width×height): 16000x12580mm

DW2-180 Double Booms Drilling JumboDW2-180 Eagle arm full process double booms drilling jumbo is specially designed for multi-step synchronous and full face excavation. The design of lengthened drill boom solves the defect that the traditional drilling jumbo cannot meet the construction needs of all construction methods at the same time.

DR1-14 Rail Single Boom Drilling JumboFeather more, this tunneling wheel jumbo is of small body, compact structure, low center of gravity, mobile and flexible. It is ideal underground machine for rock drilling projects.

CMZY2-120/18 Mining Drilling and Mucking MachineCMZY2-120/18 is an efficient continuous operation equipment integrating rock drilling and loading. It is mainly used for excavation operations in mine rock roadways, diversion tunnels and other engineering roadways. The application improves the speed of excavation, reduces the labor intensity of the workers, improves the safety of the excavation construction work, and realizes the mechanized operation demand of the rapid excavation of the rock lane.

Description of Tunnel Excavation Equipment:

A tunnel is an underground passageway, completely enclosed except for openings for ingress and egress, commonly at each end.

There are three basic types of tunnel construction in general:

1. Cut and cover tunnel which is constructed in a shallow trench and then covered over.

2. Bored tunnel that is constructed in situ without removing the ground above. They are usually of circular or horseshoe cross-section.

3. Immersed tube tunnels, sunk into a body of water and sit on, or are buried just under, its bed. Here we mainly use drilling jumbo and road header as tunnel excavation equipment to excavate a tunnel cross-section around 3.8m×3.8m to 6m×6m.

In the tunnel construction, these factors such as the ground conditions, the ground water conditions, the length and diameter of the tunnel drive, the depth of the tunnel, the logical supporting of the tunnel excavation, the final use and shape of the tunnel and appropriate risk management should be considered when choosing tunnel excavation equipment. By using the tunnel excavation equipment, the tunnels are dug from soft clay to hard rock.

Different Types of Tunnel Excavation Equipment:

1. Tunnel face drilling jumbo

(1) Divide by traveling mode: Tyre, crawler, rail.

(2) Divide by working gradient: Big slope, level surface.

(3) Divide by power supply: Dual power of diesel and electrical motor, electrical motor power.

2. Mining drilling jumbo

3. Mucking loader

(1) Divide by traveling mode: Tyre, crawler, rail.

(2) Divide by working gradient: big slope, level surface.

(3) Divide by power supply: Dual power of diesel and electrical motor, electrical motor power.

(4) Special design: with hydraulic hammer three arms, or two arms; open pit ; narrow sized.

4. LHD loader

5. Underground truck

6. Minging wagon

7. Concrete mixer
