DW2-180 Eagle Arm Double Arm Rock Drill Trolley

DW2-180 Eagle Boom Full-Process Double Boom (Hydraulic) Rock Drill is designed for multi-stage synchronized and full-section excavation, and is a rock drilling equipment to meet the needs of all methods of excavation, and is designed and developed to meet the needs of multi-stage synchronized excavation. Adopting the extended Eagle Drill Arm design solves the defects of traditional rock drilling carts, which can not meet the requirements of all methods of excavation due to the fact that the excavation of a tunnel involves many methods. It realizes the problems of synchronous excavation of multiple steps and full section excavation, and can meet the excavation of small tunnel guideway, which makes the equipment adapt to a wider range of excavation methods and working conditions, and adopts two sets of independent hydraulic system control of drilling arm without interfering with each other, so that the drilling arm can be retracted to cover a wide area, and there is a set of high-altitude service cradle which can provide lifting and lowering platforms for the auxiliary work of loading, de-exploring and hanging nets, etc. It is suitable for high-speed high-speed railway, water conservancy and hydropower. For high-speed high-speed rail, water conservancy and hydropower projects, as well as national defense and other large-scale tunnel boring drilling operations and research and development of rock drilling equipment, to meet the needs of rock drilling a variety of holes, anchor holes, small conduit support, grouting holes, etc., the machine works with a fully hydraulic drive, electro-hydraulic proportional valve control system to control the drilling arm rock drilling, smooth positioning and fast action, rock drilling speed, diesel for walking, four-wheel four-wheel-drive, flexible, the turnaround. Compact structure, low center of gravity, flexible maneuverability and stable system not only enhance the safety and efficiency, but also reduce the work intensity of the laborers.

Applicable range

Suitable for high-speed high speed railways, water conservancy and hydropower projects, and national defense tunnels below 8.5x6.8m.

Main features

High efficiency and high power hydraulic rock drill

● In order to consider the structure of the rock drilling, provide a variety of configurations for users to choose, standard Worsted A18D/L (optional A22L/D), or other types of rock drills, different rock drills drilling cost is different, so as to obtain a higher rate of drilling, shorten the cycle of operation time, extend the life of the drilling tools, higher productivity, lower drilling costs.

Hydraulic system

● Adopting international famous brand piston pump hydraulic control system to directly control the rock drilling system, with reliable quality and long service life.

● It is equipped with full-automatic anti-jamming function, brake failure warning and other protection functions.

● The hydraulic oil tank is equipped with a refueling pump for easy maintenance of the equipment, and the oil tank is equipped with a sensor to protect the machine from shutting down when the oil level is low.

● The rock drilling control is controlled by electromagnetic pump proportional valve, which makes the rock drilling system stable and safe.

● Hydraulic oil pipes are made of multi-layer oil pipes of international or domestic famous brands such as Ma brand, and oil pipe joints are made of big brands such as Sugerqiang, and most of the hydraulic pipelines have safety valves, so as to reduce the oil leakage phenomenon from the quality of the components and the source of the hydraulic system.

● With multi-faceted safety alarm system, usability and safety is very high, such as fuel oil level is too low, water temperature is too high, hydraulic oil temperature is too high and other anomalies, with alarm prompts or automatic shutdown.

● Fully-automatic anti-jamming and automatic braze withdrawal function protects the rock drill and drilling tools from damage, and there is a collision valve that automatically withdraws the braze rods to protect the rock drill when the rock drilling is completed.

Wear-resistant rock drilling propulsion

● Aluminum alloy propeller beam wrapped with stainless steel skin, polyurethane (solid lubrication block) wear-resistant liner between the movement gap, light weight and high flexural and torsional strength, long service life, can be equipped with different specifications of drilling tools to meet different drilling needs, in the drilling of large-diameter trenching holes, there is a key switching protection function for large and small holes.

Fully hydraulic flat-action telescopic drilling arm

● Adopting the brand-new double-delta hydraulic flat-action drilling arm, the telescopic distance is enlarged, and the working range is wider and higher, and the supporting propulsion assembly of the arm makes the trenching vision better operated.

● The pins on the drilling arm are designed with expansion shafts to avoid the possibility of loosening, safe, easy to dismantle, retractable, 1500mm secondary compensation to increase the drilling range, and one stop to meet the full cross-section of the rock drilling operation without the need to move the equipment.

Safe and efficient electric control system

● The electrical system adopts Schneider electric control system, which is safe and reliable.

● It has impact timing, digital voltage/current display meter/phase sequence indication, leakage shutdown protection, overload, overcurrent, short circuit and other shutdown protection.

● With emergency stop switch button.

● Equipped with horn, signal light, traveling warning.

Hydraulic Automatic Cable Reel

● The cable reel is a hydraulic automatic cable reeling system, which is equipped with a lower cable tension reversing valve group to control the cable winding and unwinding, to reduce the cable friction and prolong the service life of the cable, the length of the flame retardant cable with the vehicle is 90 meters.

Optional equipment

● Rock Drill

● Centralized lubrication system

● Grease machine, grease reel

● Hose reel

● Enclosed cab

● DANA front and rear axles

● Plateau type

● Automatic fire extinguishing system

● Alpine preheating system

Safe and efficient traveling chassis system

● Specialized wet axle and dual-road braking system, to ensure the safety and reliability of driving, chassis articulated frame, hydraulic power steering, four-wheel drive, corner ± 40 ° turn flexible, walking faster, better stability.

● With traveling brake, parking brake, emergency stop, fully enclosed wet axle, double brake system hydraulic control of the traveling brake, spring release, braking effect safety, maintenance is simple, reliable, direct, low failure.
