(-) series of ultra-powerful rock electric drills are used for drilling in rock formations below medium hardness in open-pit operations. They are manufactured according to non-explosion-proof electrical standards and are suitable for mountain road construction, tunnel construction, water conservancy and open-pit mining. Construction work in coal mines.
This kind of electric drill is suitable for blasting and blasting drilling of earth and stone in various engineering mines. Use voltage. Our factory uses silicon steel sheets and alloy aluminum steel produced by Baosteel to process gears and bearings. Advanced detection technology.

Suitable for drilling in rock formations below medium hard. The drill is non-explosion-proof and has good sealing and dustproof properties. It is suitable for open-pit mining of coal mines, dams, iron ores, aluminum It is suitable for construction of mines, gold mines, tin mines, gypsum mines, marble mines, shale, factories, mines, reservoirs, highways, etc.
The main structure of the handheld powerful rock electric drill. The rock electric drill is composed of a motor, a reducer, a switch and other parts.
Use and maintenance of hand-held powerful rock electric drill
. Appearance inspection: Check whether the fasteners of each part of the electric drill are loose, falling off or missing. The electrical switch action should be flexible and the fan must not collide with the casing.
. Insulation performance inspection: The grounding wire should be firmly connected to the casing. Use a volt-megohmmeter to measure the insulation resistance. The value must be greater than megohms.
. Inspection before operation: Before turning on the power, check whether the cable connection is correct and reliable and whether there is any damage. Then turn on the power and check whether the direction of rotation of the spindle is correct. Run idling for one minute and check whether there are any abnormalities in its mechanical parts.
The drill has the advantages of low temperature rise, high efficiency, large output, long service life and great convenience for maintenance and disassembly.
In order to operate the electric drill safely, the left and right handles, switches, handles, windshields, etc. are all made of insulating engineering plastics. The reducer reduces the motor speed to () through two pairs of gears. The drill has a simple structure and is easy to carry.
