76 - 86mm Diameter Hole Hydraulic Open Pit Drilling Machine Hand Operation

1.Introduction of blast hole drilling rig

KL551 Open-air full hydraulic drilling rig is equipped with standard 51 mm diameter drill

rod, can drill 76-127mm vertical and inclined and horizontal hole. Widely used in cutting excavation,

pipe laying, foundation engineering and the drilling in open-air mining.

KL511 equipped with heavy-duty hydraulic top hammer drill (23.4 KW). With its powerful rotary torque

impact power, Match enough washing ability and advanced control system, make it is fully capable of

in complex strata conditions exert its performance.

It is with 0-180°rotating ability of drilling rig’s frame, make a positioning drill coverage of 26.5 square

meters, greatly improve the efficiency of the rig's arrangement of holes and the ability to deal with

complicated working condition.

Drilling rig adopted high efficient screw air compressor , environmental protection and

energy saving, with completely independent intellectual property rights.

Drilling rig's power unit cross at the end of the upper rotary frame, as opposed to the drill arm and push

beam. No matter drill arm and push beam in any direction all have the effect of mutual balance.

Drilling rig's motion, crawler levelling and frame rotary can optional wireless remote control to operate

outside the cab.

2. Specification of blast hole drilling rig

     Kaishan group is a state-level large scale enterprise in China, which has been listed among the five industries of Zhejiang Provincial government, the 958 Technology Catching-up Plan and the key enterprises by Zhejiang provincial government. The group is the civilized enterprise of provincial level and contract abiding and trustworthy enterprise of state level.

In 2005, cooperating with Xi'an Jiaotong University compressor research institute and interlinking with the state 863 project, the group successfully developed a high-tech product: screw air compressor's core part : screw rotors . It marks the end of relying on import this unit from overseas only in China. The success has made Kaishan group the first in the industry which owns the intellectual property, core technique and competitive advantage among large-scale equipment manufacturers in China. In 2006, Kaishan group was awarded with a second-class outstanding technique invention award by Chinese government for this technology.
Upon the success, we are currently trying to list one of our subordinate company: Zhejiang Kaishan General Machinery Co., Ltd to the share market. Also, we are hoping to develop Kaishan group into a large-scale and diversified manufacturer with its own patent core technique and core competitiveness. We are striving to rejuvenate our national industry and develop as the pillar of Chinese air compressor industry in a yearning for greater contribution to China's harmonious society construction and national equipment manufacturing industry development.
