Drill Rig with a Bracket (engineering benchtop water drill) for Railway Maintenance Concrete Sleeper Drilling and Engineering Driller

Product Description

BF 3500W Wet core Drilling Machine

Drill rig with a bracket (engineering benchtop water drill), this machine is a vertical bracket-type diamond drilling machine (water drill), equipped with aluminium alloy/steel lifting bracket and base, used for dust-free water-cooled drilling in concrete, brick walls, stone, asphalt, etc.; widely used for air conditioning holes, range hood holes, pipeline holes, fire/water and electricity installation, road sampling, bridge/tunnel drilling, and so on.

Specification

Install Processure:

1. Installation of the drilling rig 

Take out the drilling rig and first assemble all its components.

The column, base and motor should be assembled as a single unit.

2. Installing the drill bit

Carefully install the drill bit. The drill tail thread must match the thread of the rig's output section. After tightening the drill bit, perform a no-load trial rotation to ensure that the drill bit's run-out meets the requirements before operation.

To facilitate removal of the drill bit, apply grease to the threaded section of the drill bit before use. If the drill tail thread does not match the rig's output shaft thread, use a thread adapter. 

3. Securing the drilling rig

* Push rod fixing method: usually consists of two interlocking push rods. First, select the appropriate length of the two rods according to the height of the drilling position, then secure with locking screws. One end should press against the support surface, the other end against the adjustment screw at the top of the column. Then tighten the screw in the opposite direction to firmly secure the rig, usually without the need to drill expansion bolt holes. 

* Expansion bolt fixing method: according to the required drilling position, use an electric hammer to drill small holes at the positions where the expansion bolts are required. Install the expansion bolts, then fix the base onto the expansion bolts.

4. Connecting the water supply

The water supply must be connected before operating the drill. Do not use a damaged or leaking water supply hose.

Applicable
