ProductDomestic engineering construction and open-pit mining equipment have always had several major defects: (1) the equipment is single, and some processes still use manual manual labor; (2) The degree of supporting mechanization is not high and the efficiency is low; (3) For the mining of hard rock mines, the advantages of the top hammer drilling rig are more obvious, but the domestic full hydraulic top hammer drilling rig is not cost-effective, and the customer basically relies on the high-priced imported equipment, especially in the field of engineering construction, which has high requirements for the fuel consumption, speed and flexibility of the drilling rig. In view of the above situation, the R&D team of Chigo Machinery is determined to develop a cost-effective full hydraulic jacking hammer drilling rig to fill the market gap.

1. High efficiency and energy saving
The T635 adopts a combination of high-frequency hydraulic rock drill and anti-jamming system to make drilling smoother.
(1) Efficient walking: the whole vehicle adopts a combination of heavy-duty chassis and leveling cylinder, the machine is flexible and fast when moving, adapts to complex road conditions, and has good off-road performance. In terms of walking speed, the high speed is 4km/h, and the low speed is 2km/h.
(2) The drilling arm adopts folding arm, which has a larger working range and can punch holes in the corners and corners. (See map below).
(3) Energy saving, low fuel consumption: T635 is equipped with a high hydraulic rock drill and a traveling mechanism with strong cross-country performance, and the machine has lower fuel consumption when in use.
According to the actual data collection of T635, under the condition of rock hardness F=7, the impact pressure is 190bar, the machine aperture is φ89mm, the pure drilling speed is 1m/min, and the comprehensive fuel consumption is 0.35L/m, which is much lower than similar products.
2. Green environmental protection
T635 adopts double dust collection device, movable dust collection hood and pre-separation barrel to form a primary dust filtration; The two-stage dry powerful dust collection system makes the rock drill dust-free.
Dust Catcher - Primary Filtration Dust collector - secondary filtration
3. Safe and comfortable
The operation room of the T635 machine is designed to meet the top protection standards of labor safety in Europe and the United States. (1) Wide line of sight, clear and environmentally friendly glass design when operating the cab; (2) All-round viewing range, low vibration, low noise design to achieve the best comfort; (3) The standard configuration of audio and air conditioning systems allows operators to easily enjoy the working environment; (4) Easy-to-operate control system, strong operability, easy to learn; (5) All kinds of display, prompt, alarm functions make the equipment always maintain the best working condition.
three, can completely replace imported equipment, the product is cost-effective
full hydraulic top hammer drilling rig produced by Chigo Company can completely replace the same type of imported equipment in terms of function, and the purchase price and later equipment maintenance costs are only 60% and 40% of the imported equipment, below we list the comparison chart of T635 and the same imported equipment for customer reference:

In March 2018, the T635 machine was officially delivered to an engineering contractor in Gansu. The customer used the same type of imported equipment before, and the maintenance cost of imported machines from procurement to later stage was much higher than that of domestic equipment, and after repeated comparison, investigation, and understanding of Chigo's T635 machine, he decided to buy. At present, the machine is running smoothly on the construction site. During use, the advantages of fast perforation speed, low fuel consumption and flexible moving angle are obvious, which are completely in line with customer expectations, and it is expected to purchase 4-5 more units in the later stage. Below is a picture of the machine working on the construction site.
