Z20 Full Method Straight Boom Rock Drill Trolley

Z20 series full method straight arm rock drilling cart is designed for multi-step synchronization, step method, full section and other full method of excavation and designed a digital straight type flat moving double-arm excavation rock drilling cart, to solve the traditional rock drilling cart can not simultaneously meet the needs of a tunnel of multiple methods of construction needs of the excavation defects. It can meet the needs of multi-step micro-step excavation and full-section excavation, which makes the equipment adapt to a wider range of excavation methods and working conditions, and redefines the value of tunneling dobby trucks. According to different users' demands, this series has 3 models: Z20 standard model, Z20C (with basket), Z20E (intelligent full-working method straight arm rock drilling cart), for users to choose under different working conditions. It is a rock drilling equipment specially developed and manufactured for high-speed high-speed railway, water conservancy and hydropower projects, as well as national defense and other medium and large-scale tunnel boring and operation to meet the needs of rock drilling and boring of all kinds of holes, anchor holes, small conduit support, grouting holes, etc. The machine works with full hydraulic pressure. The machine works with full hydraulic drive, electro-hydraulic proportional valve control system remote control of the drill arm rock drilling, smooth movement and positioning quickly, rock drilling speed; diesel engine for walking, four-wheel four-wheel drive. Strong power, flexible transfer, compact structural arrangement of the machine, low center of gravity, flexible, stable system, not only to enhance the safety and efficiency of the work, can reduce the work intensity of the laborers.

Applicable range

One stopping operation range: 6x5m-16x12m, full section excavation, and can meet the three steps synchronized excavation spacing 10m deep, 10m high; 

Especially suitable for highway and railroad tunnels to leave the back arch full section excavation or sub-step method of excavation in the work of the rock drilling hole operation.

Main features

Increased power options: not only doubling the efficiency of rock drilling, but also to meet the through-wall anchor cable, over the pipe shed support.

● Standard 18KW, according to the need of 22KW, 25KW high-power rock drill options, the user can choose a variety of different power according to different working conditions to choose the rock drill.

● The rock drills can be used in different working conditions to obtain better drilling efficiency.

● The 25KW rock drill is 20% faster than the 18KW rock drill in hard rock conditions.

Straight Flat Drill Arm

● Automatic leveling of the propeller beam angle for fast and accurate drilling positioning, uniform hole formation angle, and better blasting quality.

Safe

● Liftable cab and operating platform, away from the palm surface.

● The operator works in the cab, preventing injuries, and the operating platform is 8 meters away from the face of the palm, reducing the number of injuries caused by flying rocks.

● The cab meets FOPS (Falling Objects Protection Scheme) requirements, providing safety protection for operators.

Elevated console for better control of over and under excavation

● The elevated operating platform is 3m high from the ground, which is intuitive to the positioning of the boom on the top of the palm surface, without angle visual difference, and the peripheral external insertion angle control is more accurate, so as to better control the over-digging.

Dual-mode control, streamlining personnel

● Centralized console + remote control, mode switching at any time, long hole drilling can be operated by one person to control two jibs, streamlining personnel, lower cost of use.

● Manual mode: used for rock drilling operation, controlled from the cab, the cab can be raised and lowered, in line with FOPS anti-falling object impact requirements, high safety.The cab can be lifted to a high position during operation, which is easy to locate the step or the whole palm face excavation with better visibility and more accurate and faster positioning.

● Remote control mode: when used for anchor construction, the operator can carry the remote control to detach from the operating station during the header anchor construction, which makes the positioning more convenient and fast during the anchor construction.

Adaptability to all working methods

● The design of the extended boom not only meets the needs of full-section operations, but also meets the excavation methods such as upper and lower channel excavation and micro-step synchronization. Since the walking state size of the straight boom design is the operating state size, it also meets the construction capacity of 6x5m small holes. The 2500mm long-stroke telescopic drilling boom is designed to meet the three stages of synchronous excavation, and the equipment stops at the lower steps to meet the “upper, middle and lower” synchronous blasting, and the total depth of the steps is 10m.It solves the problem that the “short” depth of the drill arm of traditional rock drilling equipment cannot meet the step spacing.

Multi-purpose machine

● According to the requirement of anchor construction, it can meet the rock drilling operation of system anchor, locking foot anchor, small conduit in advance, 30 meters deep grouting hole and so on.

Deep hole drilling robot automatic connecting rod (optional)

● Optional robotic automatic jointing device, to meet the 6/9/12m deep hole anchor construction.

Short set-up time

● Equipped with water pipe reel and cable reel, no need for several auxiliary workers to pull the cable and water pipe, safe and efficient, equipment entry preparation time of only 10 minutes.

Multiple push beam configurations

● According to the requirements of the site, it can be equipped with different lengths of 3.7/4.3/4.9/5.5/6.4m drill pipes to realize the deepest drilling of 6m holes with one pipe.

Equipped with truck-mounted lubricating oil gun and truck-mounted cleaning water gun

● The on-board lubrication system lubrication gun makes the maintenance work easier, and the water gun is used for daily cleaning, which makes the equipment cleaner.
