Cembre offers various solutions for maintaining railway lines
"ECO" engines
The use of motors with a low emission value and conforming to the strictest global standards is now a Cembre tradition. These motors distinguish the drill lines called ECO and comply with “Phase 2” of the European directive.
DRILLING MACHINES
CodeLD-1P-ECO
Machinery for drilling tracks and railway equipment
Cembre Rail Drilling Machines, LD-1P-ECO have been specifically designed for use in Railway applications, to provide a consistent and accurate hole, in all types of weather conditions.
Due to their compact size, our drill can save considerable time by allowing direct operation in cases which would normally require removal of obstructions.
Special twist drill bits can be used for hole diameters 7 to 27,5 mm on rail up to 45 mm thick.
Whilst broach cutters can be used for hole diameters 13 to 40 mm on rails up to 50 mm thick.
The drills are provided with a coolant system consisting of a reservoir and pump for use with suitable cooling lubricants.
Connection to the rail drill is by a quick coupler.
The units are lightweight and ideally suited for one man operation.
Typical mounting of drilling machines
|
On the Rail Web This system is ideally suited to working when the track is under possession or if not under possession when adequate train sighting provision is in place, however removal from the rail can be quickly achieved if so required. Using this arrangement, a hole can be drilled in close proximity to a sleeper. |
 |
|
To the Rail Flange In this situation the drill slides under the rail and can therefore be left in position during the passage of a train. Work can be carried out either side of the four foot zone. |

|
For Vertical drilling This method of fi xing enables vertical drilling for the assembly of attachments to spring tongues and branch plates to switchgear boxes. |
