This year, based on several months of communication and consultation between both parties, customers ordered two Model DW1-31 tire-type single-arm tunneling drill jumbos from our company. The mining means is below the horizontal level. The lead zinc core has a main inclined tunnel of 4.5m(length)×5m(width)×4.5m (height). The excavating lane has the same size. The section area is about 20-22m2. The gradient of the main inclined lane is 12-15°. The radius of the inner turning circle is 2800mm. The depth of blast hole is 3200-3300mm. According to different excavating means, the depths of blast holes are different. The working voltage is 380v. The floating scope is 350v-420v. The largest and the smallest working temperature is -15℃-40℃. This core is sulfide lead zinc core. The core has a very high content of silica (about 60-70% silica content). The rock has a very high hardness of more than 100Mpa. The ore here has a high hardness and a poor bore-ability. Boring a row of holes at the hardest silicon-containing ore layer would consume more than one drill. The difficulty of boring can be imagined. Whether continuous and effective rock drilling can be carried out under such a mine condition is the strictest test to various comprehensive performance of the drill jumbo. From October, Siton Model DW1-31 Tunneling Jumbo received the hardest challenge at this mine.

The tire-type single-arm tunneling drill jumbo was put into operation.

The tire-type tunneling drill jumbo is equipped with an automatic cable reel.

The after-sale engineers of our company and the technical operators.

According to the requirement, the customized Model DW1-31 Tunneling Drill Jumbo is equipped with French Montabert drill machine, translation motion technology drill boom, heavy-duty aluminum alloy boost beam and hydraulic control tunneling system, effectively controlling the 360° face of this lead zinc, capable of meeting the demand of customers for the safety, high efficiency, environmental friendliness, humanity and low cost of equipment.

In October, Hu Xinhua, an after-sale engineer of our company went to worksite and conducted monitoring guidance in the aspect of operation maintenance to customer end operators. According to the feedback of the after-sale engineer of our company, the equipment has so far been put into operation for a month, and the reliability of the equipment has stood a full test, and the equipment has never broken down. The equipment has a high boring efficiency. The operators at the end of customers can operate the equipment easily. The water seal, shank sleeve and shank guide bushing and other wearing parts of the equipment are in perfect condition with a very good stability. In addition, the customer has sent a written use feedback to express their high satisfaction with our equipment!
